Corsair 450d fan orientation

[kramal]

Hey there

I'm building a pc for a "client" and the specs are determined. I was just wondering with the fan orientation. The to 780's are obviously going to spew out hot air. So i was wondering with the bottom fans (bottom cage is removed) which orientation they should have?

I was thinking exhaust, so they could take atleast the bottom cards heat. But I'm no sure, so post your ideas!

Thanks!

You want them as intakes, to get that airflow going. Also, it will keep positive air pressure in the case, so dust will not enter it as its passivly exausting wherever it can.

i'd not bother with them at all tbh, just looks cleaner
2x intake in the front and i'd switch the rear fan around and add a filter
top 2x exhaust with the h100i

That means that most of the heat produced by the gpu has to go through the H100i, doesnt it?

depends on which one he gets
the picture just says gtx 780, not dc2, so i'm assuming they're the reference ones

True, I guess it depends on his card then

Oh, don't think I made it clear but it's the Asus 780 oc

If it's an overclocked version it's a DCII for sure ( or at least a non reference one )

As a general rule for every ATX case:

- on air (or with a 120/140 rear mounted AIO): front, bottom and side as filtered intakes, up exhaust and rear exhaust ( air ) or intake ( AIO; however it's good as exhaust too)
- top mounted AIO (for the CPU): same as before for intakes, but you may have the rear fan as intake too
- custom loop: same as top mounted AIO, more or less.

I personally don't like putting top mounted AIO with fans as intakes

Positive pressure is usually the best option, like MaddenShadow wrote

I'm gonna do that then. Thanks for the input guys!
