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.

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*

Actually, no, no it does not
>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?
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.

Hey guys. I've heard multiple people comment on how the glass on the front of the Nexus 4 is smoother than any phone screen they've ever touched. Nothing to do with the software or jellybean but like the actual glass surface of the screen.
Does the LG Optimus G have this same buttery smooth glass? Has anyone been able to compare the 2 side by side?
My Nexus 4 will be arriving this week, but as I've always had SD storage on my phones, and I'm on AT&T in Vegas where LTE speeds are 15-50mbps and HSPA is 1-3mbps I'm really thinking I may sell the Nexus and pick up the Optimus G instead. But this butter screen I'm hearing about intrigues me, hopefully it's on the E970 too

Not sure about "buttery", but it is slippery as **** all over when you first get it. Be careful with this phone! After a few days of use where your hand-oils get on it, it's not as bad.
As others have remarked - build quality is amazing, battery life is great. Loving this phone... just need to get Google Wallet on it somehow
It has the same glass as the N4 gorilla glass 2.

We do also have the latest technology from LG, where they have incorporated the touch sensor into the glass. This makes for better response as well as better clarity since the pixels are closer to the screen.
I'ver noticed that this screen gets small scratches much quicker then my Galaxy SII, I had that phone for 2 years and it seriously only got a few tiny scratches through all my use. But after only 4 weeks with my OG, it has the same amount if not more haha. I may return it for a replacement as soon as my screen protectors come in.
What's your source for that info?

It feels buttery smooth to me. It's the most slippery feeling glass I have ever touched on a phone. Let me put it this way: I felt compelled to purchase an insurance plan for the phone. I have NEVER had an insurance on a phone before this phone.
if you set the phone down on any surface that is not perfectly horizontal...it WILL slide off.

I actually had it on a completely horizontal surface and it slid off LOL.
I had my phone sitting on the AT&T box that the phone came in, completely flat on my desk. 2 seconds later the phone slid off of it. This is my definition of buttery smooth.
You should check out that room with a level. I bet the room isn't flat

The other thing I've noticed is that in addition to the smoothness, it doesn't get as smudged up as my prior phones. And it cleans much easier as well, making it awesome. I hate having all kinds of fingerprints on my phone, and this one never has any due to the way the glass is engineered. Awesome stuff.

Yeah that sounds awesome, it always looks so clean in pictures.
So it's pretty much safe to say the screen, touch screen, and glass are basically identical on the Nexus 4 and Optimus G?
My Nexus 4 says it shipped days ago but still no tracking information shows up...was supposed to come yesterday and didn't and yet UPS doesn't know where it's at lol. I just ordered an Optimus G off ebay at a great price so if anything I can try both phones and sell whichever one I don't like, but I really do enjoy LTE over AT&T's horrid HSPA in Vegas. It's basically same exact speeds as 3G. So I'll probably end up keeping the OG even though I love the look of the Nexus. Just put a damn LTE radio in there Google!
This is exactly why I got the first silicone jelly case I could find even if it is normally for an LS 970 instead. Getting tired of picking my phone off the floor..

I'm concerned that because the nexus 9 uses almost the same nvidia chipset as the nvidia shield tablet, that the nexus 9 will have overheating problems. The nvidia shield got so hot that it basically cracked the case. Please let me know what your experiences are.

Hello,
From playing with mine for around an hour, it does get pretty warm but not hot enough to cause concern for me. I have seen tablets get much hotter in the past.
Subjectively, the back of mine feels about as hot as my Shield Tablet (departed). But the side/frame is aluminum, unlike the Shield which was plastic. So I'm not concerned.
Mine got a little warm but nothing hot

Mine definitely gets warm on the top half (holding in portrait) but I wouldn't say hot. Nothing unreasonable...my LG G3 gets warmer/hot.
I think the overheating problems mainly occur when playing graphic intensive games. The GPU (not the CPU) is probably the reason why it gets so warm. I wonder what would happen after a couple hours of playing Trine 2. Overheating probably won't happen under normal usage.
Anybody was able to compare how hot does it get compared to ipad? (especially ipad mini 2)
Mine gets warm, not hot.
Compared to my Shield Tablet, it's not even close.
Mine has not gotten even warm...its been plugged in for 3 hours now...setup up apps, browsed web, played a few YouTube videos fired up a few games..candy crush, slots and what not...nothing graphic intensive. Its maybe a degree or two warmer on top vs the bottom...barely noticeable. My g2 will get really warm,even hot if its charging and the screen is on. Not the case here.

Maybe the battery temp is a better indication of what the internal temp is. The outside could be warm, but the inside could be much warmer. I'm not really concerned about cracked corners like the nvidia shield had with this device, but high internal temp could potentially damage the circuits.
On a side note, it has come to attention that if you press in the middle of the back of the device, there is a lot of flex in the casing. If there is flex when pressing on the back, then there must be a space behind it. Maybe that space was intended to prevent the back of the device from feeling warm. So, it could definitely feel much cooler in the back than it really is inside.
Mine gets randomly hot. Like not even when under heavy load. I was browing the web the other day and it got to 43 C
The area near the rear camera gets warm, however I remember the Nexus 7 getting a lot warmer. I think you can probably run a Google search and find someone concerned about the heat put out by any tablet on the market (iPads included).
It's not something I'm concerned about because these chips are built to withstand a lot of heat and I suspect with future updates they may some refinement with how it runs and certainly when custom kernels start appearing it would be something we'll have a little more control over with having the ability to (hopefully) undervolt and adjust the CPU frequencies.
The Nexus 7 with the Tegra chipset or the Nexus 7 with the Qualcomm chipset got hot?
Just received mine today, when it downloaded and installed the OS update it got really hot, not unlike my Nexus 4 when it's being taxed. Battery drained a lot during that time as well.
I played asphalt8, simple rockets and plague inc for about an hour each, all games that used to set my optimus g on fire, and destroys my g2 battery. I can honestly say my battery took a noticeable hit, but it only got slightly warm. My optimus g used to get too hot to hold and then turn off. My (white 32gb ordered oct 17 delivered this morning) nexus 9 does not get hot, maybe warm like holding someone's hand. I know, this is 100% scientific, but all my other devices have gotten much hotter than what I tried to get this to. /2¢
Yes i know, i know higher speed, means more volts, more volts means more heat. however, I've come across a solution even more effective then the one mentioned in the general forum here ->. http://forum.xda-developers.com/nexus-9/general/nexus-9-mod-cooling-heatsink-mod-t2989626 that's still not enough i didn't think. so i upgraded from passive to active cooling! put part of a laptop GPU heatsink on the SoC, cut a hole in the back of the case with scissors and a sharp knife(i have no dremel or other means of hole-making) right above the newly seated heatsink and the air blows out of the top. the darn thing never goes over 50~58 degrees Celsius at full load (with a 2.5 GHz CPU OC and 985 MHz GPU OC constant).
so if it is possible, as in not hardware locked or anything, can the system handle it?
c'mon guys, anyone have an idea?

Ask USBHost. I think it would be possible to go beyond 2.5Ghz but Denver is fast...read anandtech's review of the Surface 3 & it's slower than the N9 in many areas.

I don't have the phone yet, but all the reviews have said it does make a difference in long term performance. I think it's supposed to keep things about 5°C cooler and reduces/eliminates thermal throttling. Doesn't sound gimmicky to me.
In the reviews that I have seen, that showed the backside of the cooling fan, it doesn't look like there is actually any ports that directly interface with the unit itself. But rather, from what I have read, it keeps your hands cooler and not as sweaty. So, maybe that is where the 5 degree difference comes in. If your hands are cooler and not transferring heat to the unit, then that would make sense why it would help keep it cooler by 5 degrees.

Yeah, it's the surface temp that goes down 5°C, not internal. I haven't seen any tests on internal temps, but several reviews have shown a definite increase in the amount of time before thermal throttling kicked in, and not at all in some cases.

I read somewhere the tested temp drop with the cooling fan was something like 5C to 10C on the back of the phone and 2C to 4C internal temp drop.
Allright thanks a lot guys. Maybe I'll be getting the Acc after all.
This Active cooling fan doesn't drain much battery, it's like you don't have it at all.
It's surprisingly lightweight, it doesn't make the phone heavier at all.
It comes with adhesive hard-rubber cushions you can put under it, to make the phone stand alone, just like having a pair of shoes on its feet.
The writing "Republic of gamers" on is is also RGB-backlighted, and it's really bright!
The cooling stand extends itself for half centimeter, so you can attach it easily on the phone.
And it does the job! Also, keeping your fingers refreshed, neither too much nor too little, so they won't sweat.
Above all, keeps the phone cooled enough. A must have accessory, for Asus ROG Phone 2!
I love the aero cooler, it works and cools your fingers at the same time.
