eVGA GTX 570 HD Cooling Mod ( Black plate,vrm,vram )

post #1 of 5
Thread Starter 
Hi guys,

After solving shut down problem at higher voltage , i decided to make a cooling mod . i figured out something and it is quite efficient. I had an xbox gpu cooler lying around so i took it and attached to blackplate surface area at the end of the card next to power input. I used Gelid Extreme TIM to surfaces between black plate and cooler and luckily put a rubber biggrin.gif ( rubber wont be permanant btw , i'll find someting more rigid biggrin.gif ) to tighten it between the case and cooler. Anyway, here it is ;







In photo third i tried to show that adding extra cooler didn't effect the air flow. Exhaust holes are still open.


Here are the results ;


Tested at 23 C room temperature and eVGA Furry Test ( OC scanner ) Test time 10 minutes

Stock voltage 0.95 V
Default clocks 732/1900
GPU temp 68 C Fan % 68 Extra cooler temp 42 C without fan
GPU temp 69 C Fan % 67 Extra cooler temp 31 C with a fan blowing at 1500 rpm
PCB vrm area 74 C without mod
PCB vrm area temp not tested with extra cooler

At 1.0 V
Clocks 872/1900
Gpu temp 74 C Fan % 74 Extra cooler temp 51 C without fan
GPU temp 73 C Fan % 71 Extra cooler temp 32 C with 1500 rpm fan
PCB vrm area 69 C without fan
PCB vrm area 58 C with 1500 rpm fan (blowing on extra cooler not directly to pcb )
PCB vrm area 65 C with 550 rpm fan (blowing on extra cooler not directly to pcb )
PCB vrm area 59 C with 1200 rpm fan (blowing on extra cooler not directly to pcb )


As you see I have better results with 1 V overclock with a 1200 rpm fan ( 1500 so loud for me wink.gif ) than default voltage and clocks without mod .Difference is 15 C plus %20 overclock performance. The goal wasn't the GPU temperature because i didn't add anything to directly gpu heatsink. I am more relax now i have good temperatures with a 5 bucks cooling mod smile.gif Hope you like it...

Lol nice man! biggrin.gif

I have a bunch of those gpu coolers too, maybe I should try it out...

Anyways, very very nice!

Can I see how that is done with it outside the case please? I'm just not seeing it right.

it must be done inside the case because i did not use any screws to attach heatsinks. i used some thermal paste between heatsinks ,nothing more.after that i used my 3.5 inch bay to tighten heatsinks
