CM HAF X 942 fan setup help!

post #1 of 5
Thread Starter 
I just recently got a HAF X 942, and I was wondering if you guys could give me some tips on how to set up the fans. Currently I got the H50 blowing out with the top fan blowing in, while the front and side fan blowing directly towards the GPU. since the front and side is shrouded I figured itd be best to have the top fan blowing in for the H50 but I just ordered another top fan and am trying to figure out the best position for all the fans. I dont want the top fans to blow out too much air and setting up the H50 to blow in would most likely just blow too much hot air in the case (im using the http://www.newegg.com/Product/Product.aspx?Item=N82E16835213006 in push pull config).

Any suggestions?

To be blunt I think you've got it backwards. I also have the 942 and in its original configuration it was fine. Top should blow out, h50 should blow in. Case air is always warmer than outside air and warm air should be vented out the top. Your side fan and top fan will blow against one another and the h50 isn't going to exhaust enough to keep air moving through the case. My suggestion, also having an h70, is to intake with the h50, exhaust with your top, intake with the side and fronts. This will shift your primary exhaust of warm air up- where it's going to tend to want to go anyway. Say what you want about moving air under pressure against the Norms of nature- but you might as well not work against those forces. You make your case more efficient by assisting nature, instead of wasting fans to oppose it.

I see Im gonna try that when i get home.
Only thing i was concerned with that is that my top fans might be insufficient in pulling out the air that the fans on the H50 push in.

Maybe someone else can chime in with exact specs on that top fan but with its size it moves a ton of air. I'm looking at eventually getting a second one- but my ambient case temp is such that I'm not concerned. (31c)

Keep in mind that though you have two fans push pulling on your h50 they're still only matching their individual cfm not adding to each others. The top fan can easily manage that flow smile.gif

So i tried both a minute ago and i got an odd result. When I take your advice I get 1 or 2 degrees cooler on idle but if I put all the fans on exhaust, (except for the side and front fan) I get 1 or 2 degree hotter in idle but during load I get 1 or 2 cooler.
Hows your temps?
