2x 5850s + summer weather = absurd 2nd GPU temperatures.

post #1 of 13
Thread Starter 
So it was very hot out today here on LI. At least in the low 90s with humidity. My room is an attic, not wonderfully constructed so my ambient temperatures can get close to what it is outside. For example, with the air conditioner on it my room it's still at least 60 degrees in my room, maybe 70. I don't know... it's still hot.

Onto the more important matters, my second GPU kept climbing slowly in The Witcher 2 earlier. Usually on bearable days the temperature of the second GPU will hit maybe highest 80-82c and it'll fluctuate around there. However, earlier it kept climbing until it hit 90c.

Question... is playing at those temperatures even safe, and how quickly will it degrade my card? Watercooling is absolutely not an option at this time. Money is ridiculously tight. I can't think of anything I can do since the second GPU will always be warmer than the first. Which is really stupid because the first GPU never even touched 70c.

I am going to give my rig a nice summer clean soon, but I doubt that will change much.

And before you ask, yes, I use custom fan profiles. When the GPU hit 90c the fan was at full blast (100%).

90c is getting hot but it won't degrade the card. Try placing a 120mm fan behind the cards. When I had my 480 sli setup it reduced temps by 10c.

With that motherboard you have about a 1 inch gap between your two cards right?

Are they both reference cards? Internal or external exhaust?

Having a fan on your side panel would help if you could somehow make that happen.


Also, make sure no wires are blocking airflow from the front of the case. You could try removing hard drive cages to see if that helps any.

Side panel fan.... also you can temporarily disable Crossfire and temps will drop a LOT.

No idea how I would get a side panel fan since I have a plexiglass window, I'm not good with tools either.

Could always just get a 200mm fan and lean it up against your side panel if you have room between that and your cards.

Wouldn't be pretty, but it would be effective. xD

Ok then just take off the window and tape on the fan or something.
I would really reccomend disabling crossfire and see yours temps. Should still max most games..

Yea, quick fix. Just take off the panel. Second you could get a external fan and have it suck the hot air out.

Third, get a better case or just move to a cooler place in your house or spend the money on a AC for your room.

You might also want to get some canned air or use a cheap method and get a ball pump and try push any dust out.

Take off the window an replace it with mesh. I actually prefer the understated look.

You could always strap a fan behind the cards helping to push the air out the back. Use some zipties and get creative.
