Maximum PC

I just took my own advice and pointed a fan into my GPU from the side.
8° C cooler!!

nice, I had to sticky tape two 80mm high CFM fans onto my gpu's so that they get enough forced air into all three cards. It got pretty toasty over the last few days as the weather improves, finally we are back down to 60 degrees outside so I can leave my windows in the pc room open with two window fans; one in, one out; front to back. lol

Who knew that one would use a house as a case for a computer.

It's also pretty crazy how its 60 outside right now, two window fans sucking cool air in, pulling hot air out, and I still hover around 80 degrees in the room! And its a sizable room, 30x45', two stories tall.

Yes, definitely. I have a 14 CM fan in the side panel blowing directly onto my GPU. And I have the ASUS EN.GTX580 Direct CU II dual fan and heat-pipe model that takes up THREE slots.
The ambient air temperature around the computer is maybe 65 or 70 F while the temp of the ASUS GTX580 is 147 F (64 C) running full tilt 100% on a project 8033 work unit.
In Southern California I would not go with any less than this level of ventilation for an air cooled GPU.

BTW, the CPU has it's own single fan Corsair water cooler.

I'm hoping prices for the 570/580 full water blocks get uber cheap once the 600's come out so I can finally LC my setup like point's. I can't justify spending $140 per block, but $50? hell yah! Although a number of my friends may jump on the 680 ship so might grab their LC blocks. Probably need to get a new case since I can only fit a 2x 140mm rad in it; been eyeing the nzxt switch 810.

I have 2 23 CM fans on my side panel, really helps keep heat down.

I have no fans on the side of my case, its one big window... hehe
