[Official] NVIDIA GPU Mod Club - AKA "The Mod" - Page 556

post #5551 of 8626
So I recalibrated the temp gun and set my fan speed to 55% for max load (the max I can endure without getting annoyed) and read the temperature again and it read, after 20 minutes, 63-64c..
I feel the stock heatplate is doing what it was before with minimal loss in cooling performance due to the block being there instead of the heatsink.

Anyone know a gtx 570's safe max temp for the VRM under load? If mid 60s under max load is too high I'll have to look into re-doing the mod. Idle temps for gpu is 27-28c still and max is still only hitting 39c. So if 64c for VRM is not terrible I hope to skip taking the gpu apart again.

Mid 60°C on the VRM is perfectly fine, I wouldn't worry about those temperatures at all.

Sorry about that the first time. My temp gun doesn't show in Celsius and I was too lazy to do a Google conversion the first time around =D.

I hope these are okay temps since I'm using the stock shroud and fan. Fan is set to 40% and fan profile to go up to 50% when the gpu temp reaches 39c+.

Hi, I did "the Mod" too (will post pictures later) and was a little paranoid about VRM temperature since my card doesn't shows it, so I attached a CPU heatsink fan to the back of the PCB behind the VRM's, just in case.
I saw this solution somewhere here at OCN.

Nice, if you could take some pictures I'd love to see what you mean. I was thinking about buying a backplate to help cooling for the 570, but they're hard to come by.
post #5557 of 8626
Here goes my working log for The Mod.

My main goal was to get out of the case the heat generated by the graphic card. My former card was a Gainward Phantom GTX570 that wasn´t so hot and I could overclock my FSB to 260 MHZ. Since I upgraded it to a Palit Jetstream GTX 770 I had to pull it back to 220 MHz and even so my motherboard (Sabertooth 990FX) sensors were showing temperatures over 50ºC at several places.
The GTX 770 was hiting 81ºC when playing Grid 2. I didn't run any stress test with this setup. I really didn't want to see the result biggrin.gif.

I opted for the zip ties solution since getting any bracket or adapter would be difficult, living in Brazil. Post service and our Customs are something to avoid if you can.

I got the Kraken X40 because of the lengthy tubes (40 cm) since I mounted the radiator on top of my case.

I can´t say how happy I am with the results. Running a lot of stress tests (OCCT, Furmark, Unigine Heaven and Valley) the card reached 54ºC at ambient temperature of almost 30ºC. In games it barely reached 50ºC.

To start the work I had to do a little case modding as my case isn't intended for water cooling. I cut out the top openings and made some way for the coolers tubes. Something like this:

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90




To help keeping the VRM's cool I decided to keep the original heatplate and as I didn't want to use a shim, I had to adapt it so that the X40's block touches the GPU core:







Enough space for the X40 block:



And now the zip ties:







Installing the Graphic card and a 92mm fan to cool the heatplate:



Almost the final assembly:



The "paranoid factor", as this card is factory overclocked and doesn't have VRM temperature sensors I decided to install another fan (from a an old CPU heatsink) on the back of the PCB. More zip ties here (the white ones are just a kind of "suspension" to keep the fan away from the board and get better ventilation, the black one holds the fan in place):







That blue led fan is to cool the motherboard's VRM's down

nice mod bro
what case is that?
why not try mount the gpu's x40 in the hard drive cage erea?(just an idea)

cables? you might get lower temps with a bit of tidyin up the cables..

non the less..awsome mod.

i ran a mem usage test on far cry 3..400mb only on the gpu's 1gb..gpu usage @98%
max temps 45°c...cpu 49..cores 44/44/49/44..
ps..ac unit not turn on..all windows closed.ambient room temp 22.
