Direct air duct for GPU?

post #1 of 14
Thread Starter 
My GPU is a pretty big contributor to the case temperature, running at 60c just with some flash windows open. So would it be a good idea to directly connect its exhaust port to case holes? And if so, what material should I make it out of?

The exhaust port is like 2.5cm x 1.75cm (and inch and a half inch)

what gpu do you have? and what type of cooler is on it? does it exhaust heat into the case or is it a reference style cooler that blows the heat out the rear of the case?

Brother, it blows air right into the case, however the exhaust port is very near some case holes.

It's an XFX 6870 btw.

does your case have a windowed side panel? If not it would be best and easier to mount a fan on your side panel as exhaust.
I can't think of any way that is practical to run any type of exhaust tubing from a gpu.

It's a silenced case, so it doesn't have any holes in the side panel. sad-smiley-002.gif

well a friend of mine had a case with no side fan mount and I made one, you can buy fan grills then cut a hole and
mount a fan and the grill.
other then that just have good exhaust for your case, that's about all I can come up with.
I'm sure someone else will chime in here and might have some other ideas that might work better for you. smile.gif

You can try to remove the expansion card slot covers at the back. If your case intake fans are doing more work than the exhaust fans, air will get pushed out through those slots and no dust will come in so there's no downsides to doing this.

Thanks guys. Good ideas. I have 3 intake fans and 1 exhaust fan.

Which XFX 6870? Reference with blower fan, 1 92mm side fan, 2 side fans?

What case do you have?

Sorry for late answer. A single blower fan. The GPU was at 77c today during gaming. My case is a Cooler Master: Silencio 452 with 2 extra 120mm fans. 1 for exhaust, 3 for intake, and one of the intake fans is ghetto-mounted with some sponge in the optical bracket. I have been thinking lately, and I could probably direct the GPU exhaust air using a 3-walled box around the GPU. Let me show you:



As you see, the exhaust is right next to the holes and it would be very mountable. Good idea or just stupid tho?
