What fan should I use?

[BladeZX]

I am looking to mount a fan in the bottom of the cabinet to blow on my video cards to keep them cool.

I have 2 GTX 670 cards in SLI and I want to make sure they stay cool.

What fan would be good but not too big? Would be great to be able to mount it somewhere in there.

Thanks

This may fall on the too big side but it looks like it would keep it cool and move a lot of air. basic 6

Have you actually monitored what your current heat temps are? Why don't you enable the GUI portion of the NVIDIA driver that shows you on screen what the cards are actually doing. I think you'll be amazed how little of a work out they actually get. Correction, how much of a work out ONE of the cards get. I could be wrong here, but I'm not personally aware of any emulator that can make use of SLI. So SLI for a Hyperspin setup is pretty much a waste of money. If this system doubles as your PC gaming rig then I guess I could see the additional cooling need.

Honestly stock cooling in most situation is enough (most cards have the ability to increase fan speed if needed) but if you want to add something I'd probably just add the back plates (additional passive cooling) that also help stabilize the card (eliminate heat flex) and they run ~$30 a piece.

Or you can go for quiet and effective - liquid cooling. While not so cheap, much quieter than trying to use fans to blow hot air around.

I run liquid cooling on my CPU and nothing additional on my cards. I also use an Antec case that has an adjustable speed 8" fan on top. The bigger the fan the more air that moves around at a slower speed also making it quieter.

Same thing here I use SLI in my gaming PC but not in my cabinet as no emulators use it that I ever seen.....but if you game full pc games not emulator games on your cab then ya makes sense.
