Horrible idea. It would void your warranty, and be too clunky to use

 

General idea: ok why not

Problem: i guess there simply is no place for a heatsink.

You should look for some disassambling videos before opening
your device to see if there is any place..

i yes i think the it could look like a large plate taking the heat to several directions
and then hope it will be enough ( and it wont touch anything ) or you have
to isolate this too.. plus theres no airflow.. this reduces the chances
it will work but there could still be a small possibility imo.

I think the OP is aware of this.. but still, theoretically there is a very slight
possibility. So if the op want to have fun with some amateur engineering, why not

But yes, there are a bunch of things that could go wrong and let the OP
get mad at himslef and the device

 

Yeah i know it will void my warranty but I can live with that. Airflow, on the other hand is a thing to be concerned about because I have a silicon case and that will cover the heatsinked area.

 

You have to find out the thermal specifiations of the materials you use.
Like i said, there was no airflow before in that device and there will be none

The reason i way sayin this is because you shouldnt expect some mirracles.
But it could indeed save you a small amount of degrees.

Depends on the mass of the heatsink you want to use and how it spreads the
heat.

 

I was just going to use makeshift block of copper and cut it to fit the contours of the phone.

 

BLOCK? you mean something more like paperthin
piece of metal / copper or what so ever..

Lets hope there are some 0.01milimeters for it to have place
and it wont touch anything that has electricity otherway you
have to isolate the whole thing what can take some place you dont have ^^

And again.. try to find guys that already have disassambled the phone
before opening it and having all the stress...

 

Yeah I meant sheet lol. I have watched dissection videos but none of them have this sort of modification.

 

I doubt there is a video about this sort of modification.

What i meant was more to (try to) see if its really tight inside there or
if you maybe got some little tiny space / possibility for your idea..

 

Having been a cell phone technician and working on this particular phone, this is a terrible idea. Seriously. Don't.

You will have much better results just reinstalling Android or running a custom kernal. Faux Kernel is pretty nifty.

 

Maybe he is right.. even without modification of your kernel you could downclock the phone.

@Salamachaa
but theoretically, there is still a chance it works.. it just isn´t specified by the manufacturer
so you never tried something like this, it indeed could help a little. Like i said
you are maybe right too but you cannot tell until you tried and laws of physics tell
that there is a chance

Haha yeah I'll mod a closed loop cooler and use my battery to power it all.

 

It seems like the only reasonable thing to do, lol.

 

I don't understand why rooting and down-clocking your GNex isn't an option.

You don't even have to downclock. Some kernels just run better/cooler.

Exactly. Taking the hardware modding route to current smartphones is a noob's route, unlocking/flashing is where it's at to unlock better performance/battery life. I'd look at unlocking/flashing a new kernel BEFORE I did any hardware mods.

 

check theese forums here
http://www.xda-developers.com/

 

I've been flashing ROMs and kernels since the OG Droid days. Some kernels/ROMs do run smoother and stabler but none really make the phone run cooler. Underclocking only really saves battery.

M kernal makes my Nexus 7 run about 10 degrees cooler under load.

It definately can make a huge difference.

I would put this in the same category as putting your pc in the refrigerator for better temps. Even IF OP successfully put a really small piece of copper on the thing, the heat would be trapped. There is nowhere for it to go. The copper would actually insulate because it is going to get smashed up against the side of the case. It would be like sticking a ball of aluminum foil on your desktop cpu and wondering why the temps went up.

 

I understand your pont, but heat cannot be "trapped" .. it can just migrate slower.
And - only theoretically - if there is something in direct contact to the heat producing spot
and has a larger surfacve then the chip, the heat will spread at least a very little better in the
device until it slowly gets out the phone.. this is physics dude, i did not invent it :/

no offense, and i do not want to start a flamewar here

 

I can cut out a hole in the case where the heatsink would be so the air wouldn't be "trapped".

 

lol, that wouldnt work.. theres still a cover and a battery..
i´d say try it with a kernel / custom rom first´.. you can still cut your mobile phone in half if you need to

 

Yeah, Try a Kernal and down clock the thing. I would maybe add a Few Copper Paper sticky sheets for more cooling.

Semantics. If it is moving more slowly out of the phone you are defeating the entire purpose hence the "trapped". It is just a bad move.

Also that isn't how it works at all. You are essentially taking the better conducting copper and moving it up against the case that is really poor at conducting heat. All that is going to happen is that the copper will heat up quickly and the heat won't dissipate any faster (probably slower)
