R7 260x PCB help

Recommended Posts

Posted · Original PosterOP

Getting started on a project and took apart my R7 260x, need help identifying what on this PCB needs a fan on it.  Im assuming (this is actually my first GPU taken apart in yearrrrrs) to much and couldn't find good info on this - any help is appreciated. 

 

Ive put the shroud back on and have slim 90mm 2 pin fans (PCB has 1 2pin header) so I plan to only put 1 fan (hopefully can mod to fit on the inside of the cage) in use, but will do 2 if I can find a splitter lol (and it can fit) - just not sure which shroud hole should take priority - pics of GPU befores afters as reference.

red - absolute, must have heatsink and fan , best to keep it below around 70-80 degrees Celsius - i think that's the thresholds for that generation of cards but i may be wrong, it may handle a bit more temperature..

yellow - metal heatsinks are a must, fan blowing air over them is kind of optional (would be good but not a must) vrm , the dc-dc converter which converts 12v into the smaller voltages (~ 0.8v..1.2v) the big processor needs. Those chips are often rated for 125c or 150c but it's best to keep them up to 100-110c

cyan, light blue - the vrm controller probably - it probably doesn't need heatsinks, but it wouldn't hurt to have one... it would probably be kinda hot, maybe 50-60 degrees celsius on its own, but that's safe temperatures.

green - memory chips, these will get warm, up to around 40-60 degrees celsius, and that's safe temperature for them... they're good up to around 85 degrees celsius. They'll spread the heat through the circuit board.  Sometimes, the manufacturer puts a thermal pad which connects the chip to the cpu heatsink and some heat gets radiated into the big heatsink.

Sometimes, there's holes in the big cpu heatsink and the fans move a bit of air over the surface of the chips cooling them down

So basically, you don't have to put heatsinks, but again it wouldn't hurt to have some heatsink.

AFAIK these are the most important components to keep cool: VRMs, memory and GPU chip.

@mariushm @Morgan MLGman thank you so much!  Water block with acrylic (customizable footprint) mount inc from china for the chip.  I meant to order copper HS's will do that today, and put little HS's on each of the outlines presented.  Ill attach the fan closest to the IO and there will be some airflow (1 intake fan 2 or 3 exhaust depending on fit in the case) in the case as well.  Card will be facing fan up (left handed proprietary mobo) - going to drill some holes later today :)  

 

EDIT - scratch that - aluminum heat sinks, so much cheaper lol  50 little aluminum guys with double sided thermal tape for $3.69 shipped, not bad!
