HAF X Air duct

Tavalin · 18 Feb 2011 at 21:09

Hi guys,

I've got an MSI GTX470 Twin Frozr and since it blows the hot air into my case I was thinking of using the air duct and buying a fan to exhaust some of that air out the back of the case instead.

I think the air duct takes 120mm fans so I'm looking for recommendations for the best fans to push the air out.

The GPU cooling duct which takes a 120mm fan sits in the middle of the case and blows air over the GPU.

I don't see how it can exhaust air from the case.

You could reverse the side 200mm fan and use it as an exhaust.

I think you're confused about which bit the duct is. I've linked the picture from the Cooler Master site.

I don't want the fan to actually exhaust, but I want it to push the air to the back as the grills have holes in.

If you're referring to the "Air duct designed to cool modern graphics cards" then this is designed to attach a fan to blow cool air over the GPU allowing the GPU to draw in cooler air.

No fan is going to blow with sufficient force or direction to push much air out through expansion slot blanking plates.

Is that on the assumption you're using stock cooling where the fans suck in air from the case to cool to the GPU and then exhaust the hot air out the back?

You've lost me there.

No fan attached to that bracket is going to blow air out of the back of your case. Well, possibly a very high RPM sounds like a tornado fan might.

Sorry! My last post referred to:

My point was, when they make that claim, is that on the assumption you're using stock cooling where the fans suck in air from the case to cool to the GPU and then exhaust the hot air out the back?

Do you think something like this would help then?

That product is presumably designed to draw air away from the bottom of the graphics card and out of the case. It will be pulling air away from the fans on the GPU.

I'm not even sure that the duct on the 200mm side fan will fit with one of those installed.

If you have the 200mm fan on the side of the case blowing cool air over the GPU that should keep it cool. The hot air produced by your GPU will rise and be drawn out of the top and rear of the case.

Unless you're having particular problems with temperatures I would just leave things as they are.

the best thing you can do for gpu cooling is remove the hdd bay completely and put hdd's in the 525 bays.
