Cheap SLI Cooling
 
I recently switched back to SLI and although I wasn't satistisfied with the high GPU temperatures, like some of you I keep the side of my case open since I swap out graphics cards frequently.

With an SLI configuration using the GeForce GTX 280, I was able to knock of 13 C (from 98 C to 85 C) in the Furmark Benchmark at load using a quiet running 120mm fan! This was accomplished by affixing the 120mm fan to blow hot air away from the GPUs like so:

A 120mm fan is perfect for this type of application as it does a great job of pushing the heat generated from the graphics cards out of the case while running extremely quiet.

At idle the GPU temps are running at 50 C / 49 C with a default GPU fan speed of 40%. At 50% fan speed, temps drop to 48 C / 47 C and at 60%, temps were 45 C / 43 C. Room temperature during testing was 70 F / 21.1 C.

Nice. I did the same with my 280 SLi setup and put two Yate Loon 120mms.

Helps a lot.

Is that fan facing the wrong way?

Just kidding. ::D:

Nice use of electrical tape. Although I would have used duct tape. Would have matched the silver a bit better. :D

I have that for my hd4870x2 as well (but it's primary purpose was to cool the north bridge but actually it is cooling the hd4870x2s ram heatsink as well).

Excellent idea,


I've been doing this for years.

Good idea. Maybe I should just take the side panel off mine and put a fan there like that.

I gave it a try but, it didn't help me much. This case does have a ton of air flowing through already though.

I have 2 120mm fans blowing directly on to the cards. Is reversing the fans and taking heat away a better solution?

Yes, I have duct tape and I know exactly where it is!
