Fans everywhere.

post #1 of 5
Thread Starter 
I've got a HAF 932 and I'm thinking of crossfiring my 6870s. I hate heat just as much as any of you guys. So to keep my 2 6870s at a reasonable temperature I was wondering if I should replace the side 200mm with 4 120mm fans AND/OR replace the top exhaust (a 180mm fan I think) with another 3 120mm fans.

I dont know much about after market fans and we're talking abou buying up to 7 fans. What's the best price performance 120mm fan out there (I'd like it to not be too loud also) and what kind of temperature change can I expect (ambient between 25 and 35 Celsius)? Is it even worth the effort?

If you're looking for price/performance fans I'd recommend Yate Loons. Also the big fans on the HAF are actually 230mm fans. (Can use 200mm fans as well though.)

Thanks but after a quick search I found that no one in Australia sells Yate Loon fans.

Any other recommendations?

The big fans in your haf 932 flow quite a bit of air (110 CFM according to their site). If you add 120mm fans I don't think you will gain much without adding quite a bit of noise from the smaller fans spinning faster.

Using two HD6870s Twin Frozr II inside a HAF932 needs some good planning. I recommend:-

1) First and foremost, make sure there is (at least) one empty slot space between the two cards. I cannot determine your motherboard just from your sig rig. But if your mobo gives two empty slots in between, it will be much better because this type of coolers (Twin Frozr II) needs space for good intake.

2) I recommend a 'top-exhaust' approach to manage the airflow inside the case. Simply put:-
2.1) four 120mm fans on side panel as intake (speed controlled by a fan controller). These supply cool air to the 2 cards as well as to the NH-D14.
2.2) three 120mm fans on case top as exhaust. These create a strong upward draft to extract all hot air inside the case via the top
2.3) case rear fan as slow exhaust. It mainly serves the sole purpose to prevent warm air from case rear to creep in.
2.4) case front fan as slow intake. This cools the HDDs.
2.5) your NH-D14 to be reoriented so that it exhausts upward. This is necessary so that hot exhaust from the the cards' front will not go through the cooler

3) Read thoroughly this thread for an actual practice of handling two graphics cards with Twin Frozr cooler inside a HAF932. The CPU cooler was a Corsair H50 but your NH-D14 can just do similarly.
