Tips to keep SLI GTX 460's cool on a Gene-z mobo

post #1 of 9
Thread Starter 
As you all probably know, ASUS's Gene-z mobo is a SLI/XFire capable uATX board. I recently switched out my 6870 for SLI GTX 460's. The problem I have is that the top card idles at 50-60C and hits 85C at load. Does anyone have any tips that might help keep the temps on that top card down? The bottom card has no issues, hits 50-60C on load and idles at 30-40C, even with the top card blowing all its hot air onto the back of the pcb.

The cards are MSI GTX460 Hawks running at stock clocks.

Thing is about the Twin Frozr coolers is that most of the heat gets expelled out from the GPUs into your case. You will need good exhaust in your case (rear and top) and good intake fans from the front and bottom to help improve the cooling for these cards.

But honestly 85c on load isn't too bad. It's not like it's going to overheat and burn out or anything. I think the cooling potential is really within what your case and fans can offer. Air Penetrator fans are good for pushing air up and out of the case.

How many case fans you got rocking? Id have a fan in every spot my case will let me. In fact I do! Ive got 5 fans. 4, 120mm and 1, 140mm. 3 of the 120mm's are running intake and the 140mm and one of the 120mm's is running exhaust and Im getting very nice temps on my CPU and GPU.

I was thinking about replacing the stock case fans with fans that can push more air. The stock fans are REALLY weak.

YIP, more fans.

Ive got 10 right now and thats not including 2 for the gpu another in the psu or ram fans. Just havent had the time to hook the rest up yet thumb.gif

I have had excellent results by simply mounting a fan at the rear of the case, exhausting the two 460s. Dropped temps by 4-5 C.

Also made a side fan, which dropped the top card's load temp by 2-3 C.

Running unigine heaven benchmark at 825 core 0.9875 volts, cards are maxing at 54 and 53 C.

Another thing you could do if you have the room, is cable tie a 120mm fan on the inside of your HDD cage at the top. (Motherboard area side)
That way it'll blow air directly between the two 460's, feeding the one in the top slot, aswell as dispelling the head from the backside of the bottom card toward the PCI slots (I meshed all my PCI-Slots).

I'll try both those things and see how the temps fair. Thanks for the tips.

Just put some IC diamond on my gpus...

Temps have dropped 3C for each card! specool.gif

Max temps after running heaven benchmark for 30 mins with an OC of 825 mhz core are 51C and 50C.

Just to make sure, all my recordings have been done with similar ambient temps with difference of 1-2C.

Good Luck!
