Prime cooling - Asus Eee Pad Transformer Prime

Does anyone here have any insight into how the prime is cooled? I am wondering if the backplate is being utilized at all to assist in cooling?
Is the soc facing the screen or the backplate?
As much as the backplate may interfere with wireless signals, it may be able to help in other places..
Also, while it may be minor, decreasing temperature at a particular clock speed and voltage will decrease power draw on full load. Maybe able to squeeze a few more minutes during gameplay.

for wanting to know which way the Soc is facing. just look at the GPS teardown thread. I know I posted tons of pix in there that'll answer that. can't remember which way it was facing.

---

The tear downs have like a grounding ribbon going over the chip and it provides some of the cooling, or at least that's what the tear downs call it.

---

Has anyone taken the motherboard out yet? I am waiting on my thermal paste to implement a custom cooling solution but do not want to break the motherboard in the process.
Thanks.

Why do u want a custom cooling solution? This thing ain't getting very hot lol..

Someone has been reading about the new iPad temp reports

I'd like to be able to dissipate heat better. The Prime generally stays pretty cool, but when running at strictly 1.6 GHz for about 5-7 minutes mine can get as high as 39-42 C. But it's not like I ever have a reason to actually run it at the maximum for any extended amount of time
*EDIT:
Well, something must have been off when I did my OG test, because doing the same thing I used to (set SetCPU to 1600/1600, ran AnTuTu Tester battery test) I'm 10 degrees cooler than I was. Something that allowed the use for all 4 cores must have been running in the background at the time without me noticing. As soon as I find a good way to monitor temp while doing other things I'll engage all 4 cores and see if that brings me back up to the same levels.

Heat is a by-product of current (resistance). Decreasing the temperature has no impact on power draw. There's no convection cooling, thus no fan to draw power in order to cool the internals.
I'm all about efficiency myself, so it's cool you want to do this, but just make sure you're going to end up with the results you want.

Maybe I am misunderstanding?
Look, I have a cpu that requires say 1.4v at 60c to perform at 3.6 ghz.
I then put that same cpu under water cooling. It can now run at 1.35v at 40c to perform 3.6ghz.
1.4v x (???)amps = (???)watts
1.35v x (???)amps = (???)watts
As temperature increases it becomes inherently harder for electrons to flow therefore requiring additional voltage. Additional voltage alone increases power. Now as the temp goes up more current is required to perform the same task which means even MORE power. Temperature means exponential power draw.
I'm not arguing this is just what I have learned by surfing pcper for the last 6 years or so, if I am wrong please let me know why so I can feed my hunger for hardware knowledge =)

Like I said, I would love to lower temps so i can run over 1.7ghz. My prime runs decently hot at this frequency.
Also, I will not be stopping with cpu, I need moar gpu power too! Rawr!
Edit: I suppose I didn't say I wanted to run higher but yeah, I want to overclock this b?!# until it melts. Tegra 3 on phase change anyone? Lol.
Also it seems like its going to be crazy easy to help with the temps once I get the motherboard off.

What do you use to monitor temp my friend?
Edit: it seems like if I can get my penny mod to the correct height it will have direct contact with the backplate!!!!! Probably a 2-10 fold increase in both dissipation and heat load. Exciting stuff!

Just the SetCPU widget on the homescreen, and AnTuTu Tester shows you the temperature when you test the battery. Right now Tester only uses two cores though.

I would love to see the prime pushed to 2ghz.......wow
im all for pushing a machine till it melts...lol lets do it. i would def impliment a/your cooling method if it gets going.

Two cores on one die? IE core 0 and 1?

Right, only cores 0 and 1 (of course I don't know about the Ninja core, no app will ever be able to see it) get fired off using the AnTuTu Tester app.
Soon as I find a taskbar "widget" to display temp (or optic76 updates TabletCPUMonitor to display it) then I'll go about stressing all 4 cores at once. Now that I think about it, SetCPU has some configurable stress tests huh? *hops off to have a look*
*EDIT:
Actually, no, no it does not

Metal-clad units like the iPad and Prime have slightly better cooling, simply because the aluminum transfers heat better than plastic. But the shell isn't directly used as a heatsink per teardowns.
That would actually be a bad idea, as while internal temp may be lowered, surface temp would drastically increase. Given that the surface is in direct contact with your hands/skin, it can cause great discomfort and possibly burns. Ever touched a heatsink?
There is no good cooling solution for tablets/handhelds because of the lack of space.

I'd like to see some screened grilles/grates and tiny little dyson fans or something lol

Yes I have touched a heatsink. In fact I've touched, cut, modded, complained about, and raved about heatsinks. I'm all about the thermals. What your saying makes perfect sense and all but I've already considered all of the above. When I unlocked my prime I had one goal in mind. Overclock it until it melts! Why? This is how I have fun with my toys, I enjoy it!
Now the facts: yes it will be hotter, but it will dissipate quicker due to better/ more efficient thermal transfer. So that means it will cool down quicker, while also taking strain off other internal components such as power regulators due to a much lower ambient temperature. In turn this will allow for cleaner power delivery and hopefully higher cpu and gpu clocks.
Plus....all the cool kids are getting burned by their tablets. See: new ipad.
