Help me Cool my GTX 570 SC HDs

post #1 of 4
Thread Starter 
Hello all,

This past week I installed my 2 EVGA 570 SC HDs (my rig is listed in my signature). (Please note: that the HD version changes the cooling from the stock 570) The cards run well but I am having some heat issues. The two cards idle at 37C and 35C but in games the top card sometimes gets into the low 80s with the fans at 85% and at 100% utilization. (The second (lower) card runs about 8C cooler at 100% utilization, usually topping out at 75C, which I am fine with). From what I understand, 85C or below is fine for long term use, but I would like to get the temps down anyway.

I do have the latest drivers and I run custom fan profiles through Precision (basically whenever the temps go over 75C the cards go to 85% fan speed). I haven't downloaded the fan unlocker because these cards are too loud anyway at 85%. This is the one area I am disapointed with these cards. My old 2 x EVGA 8800 GTS 512s were never nearly as loud even at 100% fan but I guess that is beside the point.

My case has front and side 200mm fans for intake and a 200mm on the top for exhuast as well as my H70 in place of the rear fan as exhaust.

I was wondering what would be the easiest steps to reduce the temps on my top GPU (i've done a fair job with the cable management and any improvements probably won't make much of a difference). One possible solution I've seen is fan cards. The following are two examples: http://www.newegg.com/Product/Produc...-112-_-Product or
http://www.newegg.com/Product/Produc...-065-_-Product

These are few complications, however. First, I only have two PCIe slots available, and they only have room for single slot cards/fans. One PCIe is right above the top GPU and one PCIe slot is right between the top and bottom GPUs. Both GPUs face downward (fans face down). Also, I have only been able to find fan cards that plug into the MOBO that use normal PCI and not PCIe. So, that may limit what I can use.

So, my first question is what type of cooling solution should I try? For example, is it best to get the cooler that uses two fans to blow additional air on the top GPU? Does it matter if the cooler is above or below the GPU? Or, it is better to use one of the coolers that helps vent the hot air out of the case? Any other relatively easy possible solutions?

Thanks for the help!

I don't know where your comp is but when I have high temps I just throw a box fan next to my rig with the side panel off (doing so right now). It brings down temps on my GX2 by a fair amount and it's cheap. If your rig is in an area where you could do that I'd try a box fan. Though if you really want low temps you could buy an aftermarket cooler for your 570s like an Accelero Xtreme, that would lower your temps while letting you keep the side of your case on (though it would be expensive). I don't really believe in those fan cards that you linked to as they just move hot air around in my opinion. So if you are low on cash I'd buy a box fan, and if you've got money to spare I'd buy an aftermarket cooler.

You are going to have to do something about removing that hot air from the case. Sniper owners will know best, but it looks like replacing the top 200 with some good 120's should do the trick.

So, my top GPU, the one that was running hot, crapped out on me today! The card never went above 80C, but in the middle of playing BFBC2 for a few hours my computer just turned off suddenly. I tried running other games or 3DMark and after a few seconds my computer would just reboot. I was afraid that my PSU might have gone bad. But, I tested each GPU by itself and the top GPU caused constant reboots whenever a load hit it (starting a game, 3dMark). The other GPU, however, ran 3Dmark on extreme with no problem. Also, it runs a lot cooler! So, maybe the relative high heat on my top GPU (compared to the second GPU) was indicative of a bigger problem with the card.
Time to RMA!

UPDATE Part 2:

So, the non-defective GPU runs a good 10C cooler playing the same game BFBC2, topping out at 70C. (The other GPU would previously go up to 80C on BFBC2 whether in SLI or not.). Pretty interesting I think
