UPDATE:
I wish I'd done some temperature benchmarking beforehand, but instead sourced the community to help out. Check out the various results on XDA... there are also results from two TF700 owners (in Europe) who were gracious enough to help me out.
http://forum.xda-developers.com/showthread.php?p=28051518
First, it seems clear that my mod really didn't mitigate the heat issue enough... so don't bother.
Second, comparing the numbers between other A700's and the TF700... well, I'll let you draw your own conclusion on that one. :-(

Hi all,
As many of you have experienced, the A700 can get very hot under certain conditions. Mine got extremely hot to the touch after just an hour of gaming (Heavy Gunner, NFL Flick QB, and Cut the Rope), and crashed 2 or 3 times.
Well I decided to do something about it. Reading through the Service Guide (thank you paugustin!!!) & A700 teardown photos from another site, I came to some conclusions. First, from the looks of things, the back panel has some kind of metal plate lining, and 3 "pads" that closed the gap between the metal plate and several surfaces of the mainboard. My hope was that these pads were not simply foam pads but were actual thermal pads. I guessed that a bit of thermal paste might help the efficiency of those thermal pads... and if I got really ambitious, I could replace the thermal pads with larger ones (and paste those too).
Service Guide:
http://forum.xda-developers.com/showthread.php?t=1716922
I followed the instructions in the Service Guide & opened up my A700 earlier tonight. I'm pleased to report that as long as you take your time, it's super easy to open up.
And lo and behold, my conclusions were accurate... the back plate is copper and the pads were thermal pads!

Afterwards, I slapped everything back together, fired up NFL Flick QB and played for a half hour. I'm pleased to report that the A700 got warm but nowhere near as hot as it did in my prior gaming session. The "level of warmth" was what I'd consider mildly warm, comparable to my fiancee's iPad3, so definitely within reasonable tolerances.
I still intend to put the A700 through some more intense gaming tomorrow, but I wanted to write this post up and share it with everyone first. Hope folks find this useful and insightful!
Nice discovery, but yikes! Thermal grease is meant to go on in a translucently thin layer or it ends up having the opposite effect! If you put that much between a CPU and it's cooler, you'd kill the CPU! :S
superawesome!
Yet still i'd like to wait for more people to evaluate the hardwaremodding before i go in there myself.
Still, kudos to you. :good:

Except in this case, the thermal grease isn't going up directly against the CPU... it's going up against a thermal pad & large metal plate that is covering the entire mainboard.
Additionally, unlike a heatsink & CPU which are fitted together tightly, the back panel of the A700 & thermal pads do not contact anywhere near as tight to the mainboard plate. I fitted the two halves together, then pulled them apart again, to see how much the paste really spread out. This way I could better gauge how tight the contact was & remove any excess that got squished out. However, not much paste really did, telling me that the compression between the two isn't that great. That is why I'm toying with the idea of replacing the thermal pads entirely.
Hey, good stuff. Keep us in the loop on this....
Thicker thermal pads might be in order, or a better paste job under the plate on the CPU/GPU...
Bigger pads to spread the heat out more since the back looks to be one copper heat sink..

Then be happy that you're amongst the enlightened!
CAUTION!!!!!
OK maybe that's a bit strong, but as an engineer I have to question the logic employed.
First of all, the heat generated by the CPU, battery, etc. must exit the device. ALL OF IT!
Temperature of the back plate is determined by two factors alone: thermal resistance (e.g. insulation, heat pipes, air flow, fins, etc.) and the amount of heat transfer. I'm serious!
It appears that you have done nothing to affect the thermal resistance between the back plate and the air (e.g. adding cooling fins or increasing air flow). Therefore if your back plate temperature has decreased (and the air temp stayed the same), then we would conclude that heat transfer between the back plate and the air has DECREASED.
If hea
If heat transfer from the plate to the air has decreased, then that means the heat transfer from the CPU etc. to the plate must have decreased as well!
My guess is that your thermal paste is producing a higher thermal resistance, as predicted by FFM! And it's deceptive because it's insulating the back plate from the CPU etc.
So where's the heat going? (I hear myself asking... myself.)
My guess is that it's dissipating through the tablet, getting distributed and absorbed and ultimately emitted more uniformly from the device. This would raise the internal temperature of the device, including the CPU! Hence the CAUTION!!!!!
Your idea could have some benefit, though, and here's how i see it playing out:
If you decrease the thermal resistance between the CPU and the back plate, then the CPU would be closer to the temperature of the back plate (i.e. lower). But the back plate temperature won't really change because you still have the same total heat coming through and the same thermal resistance with the air.
As for spreading the temperature across the back plate more, I'm not sure you can do it more effectively than the copper plate that's already there. Not without insulating the most direct heat transfer path!

Right, I'm aware of this.
The exact problem I was attempting to mitigate, is the transfer of heat between the mainboard cover plate and the back panel copper plate. I was theorizing that the thermal pads being used were not fitted well, thus not functioning optimally as designed to begin with. As a result, not enough heat was being transfered to the back panel copper plate for proper dissipation.
So either heat is being transferred to the back copper plate more efficiently now and dissipating more effectively... or the opposite as you proposed.
However, if heat transfer has decreased, wouldn't heat buildup would still occur within the small area between the back panel & mainboard? While it wouldn't be absorbing the same amount of heat directly from the thermal pad, heat would still build up over time and that should still be noticable no matter what, right?
I'd also note that the BETTER solution would be to NOT combine thermal paste with the thermal pads, since as you point out, that can adversely affect thermal resistance.... but rather to replace the pads with better pads.
But I decided to be a guinea pig and try it out anyway.
Sorry I got distracted before posting my conclusion:
So my conclusion (prior to your latest comments) is that you can effectively lower the temperature of the CPU but not of the back plate. (unless you're insulating it from the CPU, which will spread the heat around and raise the temp of the internals!!!!).
I will consider your latest comments and repost!
The way I see it, the heat was not effectively transferred to the radiator. We have to remember that the case heat-up experienced by touch is not only the radiator, but the case itself heated by both the radiator and the air.
I'd assume that lack of crashes indicates smaller temperature of the CPU\GPU, as the heat is conducted more effectively by the paste to the radiator and dissipates evenly, instead of building up in one place and transferred to the case by air.
It's times like this, that highlights the one minor missing flaw of the A700... there's no bloody temperature sensors that we can poll!!!
*bashes head against desk*
So unfortunately, all findings are really subjective unless yeoldeusrename's conclusions are correct and mine are totally incorrect, and my A700 decides to fry itself.

Well, i wouldn't be that sure. The A510 has them (at least separately for cpu and battery) and can be read by certain apps from the store. (E.g system tuner and battery monitor widget) so i would guess the A700 has them too.
Perhaps that helps

The two apps I tried, didn't show anything for temperature, but I just grabbed system tuner & it does register cpu temp! Yay! Will explore the app further to figure out how to record history for accurate metrics. Thanks for the hint.

Beginning to wonder if the heat and touch issues are why the 700 is priced the exact same as the 510. Nothing else apparently makes sense.

I think I'm going to look into creating a heat shield to place against the rear cover.
2 to 3 inches across and 4 down on the right side should do it.
This is a great tablet otherwise and don't want to give up on it just yet.
Besides the Asus sound system is inferior.
Hi I had purchased a Galaxy Note 10.1 recently and have been playing around with it. A concern I had was that on the upper left backside of the device, below the silver plate on the white surface, the device feels warm compared to other areas of the tablet when using any apps. Is this normal or not?

Hi erica, how long have you had your tablet? Has it ever really bothered you too?
"Feeling warm" is normal for anything with a modern CPU inside it. If you put your hand directly on the CPU (or the heatsink covering it) in a desktop or laptop computer you may burn your hand since it can reach huge temperatures of 60 degrees plus.
This review shows the Galaxy Note 10.1 to reach 45.9 C on one corner of the back when under maximum load:
The Samsung Galaxy Note 10.1 had no issues regarding temperature. Even after long periods of full utilization during our stress test, the Galaxy Note did not become excessively warm. While the upper left corner exhibited slight hot spots on both the front and back side with temperatures of 45.9 degrees Celsius (115.6 degrees Fahrenheit), this temperature is still rather trivial considering the fact that our test was conducted on a hot summer day. During daily use, the surface temperatures of the tablet remained comfortably cool and under 33 degrees Celsius (91 degrees Fahrenheit) at every measurement location. The internal components showed no risk of overheating in any case and even the AC adapter barely warmed up.

Since it's plastic, that'll never feel "hot", just warm.
You should rarely reach maximum load if you use well-behaved apps, though some games will tax it a bit. It's actually pretty amazing what processor power can be achieved in this thing without getting too hot or requiring a fan, thanks to the ARM architecture.

So if the tablet reaches 52 C, thats alright? I really don't know specifics like this at all but would a tablet such as the asus tf700 feel the same way? I mean heat wise on a everyday medium load?
They actually get considerably warm being they are made out of aluminum. I had the tf201 and 700. It's not too hot though but you notice it
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
I am using system tuner to see the cpu temperature and I am getting high as 55 C. So I am in the green right? What is the highest the temperature can be and my tablet can still have a good lifespan?
A few things:
1. When I pointed out the review of this device that said it got to 45.9 degrees, that's the surface of the outside of the case. That's different to the CPU temperature, which will invariably be hotter.
2. Tools that report CPU temperature are invariably misleading. There are so many different ways to measure it that mean different things and sensors can be calibrated differently on different devices. I'd say leave it up to the engineers that built the tablet and trust that they built it to tolerate any heat it generates, which they will have had to.
3. Aluminium of the TF201 won't be getting warmer because it's aluminium, it'll just *feel* warmer because it's aluminium - even if it were the same temperature. It conducts heat to your body more efficiently as a metal. As a result, the case itself will actually help cool the tablet better, but don't go assuming this makes aluminium cases better - the engineers would have accounted for this in their thermal design, and we're not talking about all that much heat here anyway.
At any rate, this tablet doesn't get hot enough to worry about - far, far from it. The amount of warmth you feel is normal and in a tablet like this will never get close to approaching the heat required to reduce the CPU's life (unless something goes terribly wrong or you put it in an oven or something). It's not even worth worrying about. I'd worry more than in 3-5 years' time the battery capacity will have deteriorated to the point where it'll give you noticeably less battery life - because that will happen. If you're going to worry about overheating, worry about your laptop instead. If its little fan stops, is blocked or fills with dust, it is actually *quite likely* to overheat the CPU eventually - not that you're likely to notice, as the CPU will just throttle down.

I am wondering if anyone has thought of or even tried removing our new GPS/ WiFi panel from the back of the Tablet. What I am thinking of is to cut/ drill holes in it to increase ventilation to allow the heat to dissipte easier. I have seen something similar built it from the new Asus ZenBook. I am thinking that this could possibly allow us to run some of Clemsyn's higher 1.9 or 2.0 Over Clock kernels easier or allow him to go higher with the GPU? I would be willing to try this myself if I could find an easy way to remove that back piece without needing to remove the screen from the rest of the tablet. I am however not sure if it could harm the tablet more then it could help it. I would love to for some advice and suggestions.

Hey fellow GR TF700 owner! Nope, unfortunately there is no way to remove the back piece without removing the screen, ect. You are really talking about a full tear down of the tablet, and rebuild after adding the vents. Sounds like fun though, I am an avid PC modder and if you are looking for a partner in modding, look no further!
If you want an idea of what you are in for.. check this out:

Thanks for the input. I didn't know there were so many XDA member from the West Michigan area. I am still debating on performing the operation on my Tablet and I have in fact seen that tutorial. I am just still not sure if it would in fact be a positive. I know that I would have to put some sort of mesh on the inside to prevent dirt from getting inside. I just always notice that my tablet can get arm on the top left corner after a while even if I am using the keyboard. I noticed this even before I unlocked and also recall it happening on my Prime.
It would seem that your warranty may not cover this if you messup on it. I got this info here. Just thought I would give a fair warning
Thanks for the fair warning. I already figured that the warranty would not be valid after i put holes in my device on purpose. I am just trying to figure out if it would in fact help lower the temperature of the device with ventilation holes. I know that our tablets may not be up to standards with actual lap tops or computers, however I do believe that we have better processors internals then early PC's and they even had cooling fans and better ventilation. I do know that we have devices now that are way to thin to put cooling fans or liquid cooling tubes, but why would it not help to put well places ventilation to help our device run cooler and more efficient. I notice that the biggest difference when my devices starts to get hotter is that the battery drains quicker. I have noticed this with any device I have overclocked that once the temperature starts rising, the battery starts dropping quicker.

Heat is a form of energy, so the reason for this should be obvious.
When I get the parts delivered I'll be doing a touchscreen and battery replacement on my TF300T. Looks a lot easier than the phones I have repaired -- more room to work -- the several videos spell it out well.
But I ask: Is it a wise idea to replace the thermal paste on the copper plate? And if so any brand recommendations or are there any incompatible thermal pastes out there to be avoided because of their composition? I notice the back of the tablet gets quite warm at times.
As for the touchscreen: I can see the screen is badly marked after close to 7 years of use. The letter "i" on the virtual keyboard is dead, and I can no longer swipe properly in twrp recovery. Swiping the wipe page will cause other partitions to be selected. Fortunately the swipe never succeeds in launching the flush or format.
Could this be a symptom of another more serious hardware issue -- the fact that the touchcreen is totally useless in twrp but only a little broken in user mode?
Thanks
Cheers

Please note, you don't need any clue because the thin copper heat sink, shown in step 1 of the video, is self-adhesive. Take off the heatsink carefully by a light spin. Some glue fixes it on the CPU. On the left and on the right site are black or grey tapes. Remove the tapes carefully. Keep all together safe during the repair.
As you can see on the video the last step will be to put the thin copper heat sink back again with a light press down. It will stick again like before.
Did you meanwhile get the touchscreen of your device replaced successfully?

Get the aeroactive cooler or reduce your gaming settings using Armory Crate. The hardware was designed with the assumption there would be additional cooling available.

I already use lowest settings for my phone but it's still hot even when I play it at room with air conditioner. Is it normal for this phone to reach 43 or 45 degree when I use to play games?
I never actually tracked the temp, but mine does get warm. If you're in a room that's already warm, that will add to it. If you have a case that isn't properly vented, that will add to it. If you are playing games with intense graphics or constant internet, that will add to it. It's really built for speed and performance, but it seems like they didn't test heat much in real world scenarios.
Check the autostart manager and remove any apps you don't need booting with the system (ie. If you use root explorer, but not the automatic launch, it can be disabled). This also helps with battery life.
You can tweak memory management in Developer Settings to kill background apps faster so less is running both in the background and when it's not being used. This is more for if you are switching between a lot of apps.
I would avoid messing with voltages much unless you know what you're doing, but you can always cap the cpu using a kernel management app. If the issue with building kernels ever gets sorted, we will also have better thermal control.
In addition to lowest possible settings - Undervolting the GPU by 1-2 levels (e.g. using Konabess) definitely does help as well as debloating unnecessary background running apps and sync. Also disable 5G. The Aero active cooler helps a bit too.
But this device is ultimately lousy with both temperatures as well as battery life considering it packs 6000mah. It seems to be clocked way too aggressive for real life use including gaming...

Apps like Google play Services, Backup Transport, Framework and anything running in the background or using data needlessly is the enemy. Cloud crap is just that. Carrier, app and manufacturer feedback not needed.
Optimize the device and take out the trash.
A damp microfiber cloth can be used to cool especially if it's a dry environment.
Don't depend on thermal shutdown to save your device... it can fail you miserably.
There is no IP rating on the ROG Phones, meaning they are not even the least bit water resistant. Just something to keep in mind.
https://global.blackshark.com/products/black-shark-gaming-cooler is a little bit more complex than the aeroactive cooler and ironically about 1/3 the price.

Most phones have some sort of water resistance in 2021, so it's only fair that some may not think too much about pushing a bit too hard on a damp cloth and getting the phone wet.
... You could also just put a cloth in the freezer for a minute and save the trouble of having to worry if you used too much water.

As hot as it's running it would drive any moisture out ie an old school hot box. A moist microfiber cloth will do no harm, but eventually it won't thermal shutdown in time... game over.

... You could always feel the device is getting hot in your hand and shut it off manually before allowing it to fry, but that is common sense.
Edit: Seems the verdict is that the warning should remain posted.

I live in the desert and have seen thermal shutdown fail to protect devices.
I use what works.
I never assume "waterproof" devices to be so... many are not.
You once a guarentee? Where will you be in a 100 years?

There is no IP rating on the ROG Phones, meaning they are not even the least bit water resistant. Just something to keep in mind.
https://global.blackshark.com/products/black-shark-gaming-cooler is a little bit more complex than the aeroactive cooler and ironically about 1/3 the price.

I feel like I read somewhere that these coolers were causing discoloration on the phone itself. Others have also cautioned that the extreme cold vs extreme heat of the 888 may create moisture inside the device. This stuff is a bit over my head, and I have no proof of either of these being true.
Have you heard or have you seen anything in regards to his cooler? Its very clear the Aeroactive cooler is not enough, but is the blackshark one too much?

Ironically, I was the one who posted about that. Some reddit users reported it, but that was for the previous design. I'm not sure if this one has the same issue, but it appears to have taken the right steps.

I have the Aeroactive and have used it. No discoloration noticed (at least yet). It's mostly gimmick with respect to cooling however. I mainly use it for the trigger buttons and the kickstand when doing video calls.

Not that one. The Black Shark. The shape of the clip limited how much the cooling could be spread over the back of the phone.

It's hard to see in the photo, but the side facing the phone is now a full plate that will spread the cooling a bit more evenly.
You could always put a damp cloth under the fan and hot box your car.

Not that one. The Black Shark. It was because of the cooling chip being too focused on one specific point (see below).

The new design added a cooling plate the full "height" (landscape) that will spread the effect a little more evenly.

Ah my bad. Haven't tried the Black Shark. A more efficient solution for these external coolers might be if the device case section above the hot chips are made out of high conducting material (like CPU lids) and in direct touch with the chip surfaces on the inner side of the case (again, like a CPU lid).

Active peltier cooling can do this if the inside of the phone drops below ambient room temperature moisture in the air can condensate. If the cooling isn't temperature regulated above ambient temperature, the RH is high and the device is poorly sealed this maybe an issue.
Simple fan cooling won't do this.
Heat displaces moisture rapidly which is how a hot box ie dry box* works even in the tropics. This is why you can get away with a damp microfiber cloth as long as you don't drip/seep water into the phone. Because of the heat generated by the phone small amounts of moisture inside dissipate rapidly.
*a small incandescent bulb in a semi sealed cabinet. For cam lenses, surgical instruments, or anything that's moisture sensitive. Some are huge glass cabinets heated with sealed steam radiators, some glove box small heated with a 5W bulb.
