cooling advice intake vs. exhaust

[Freshgeardude]

hello I am building a computer and a small problem arose when thinking about it. I want to use this case(from mfg website)
case from newegg
which states that there are (3) 80mm fans(1 on top 2 on side) (1) 120mm fan(back) and a 120mm optional(for front). In the MF website it says that all fans are exhaust and the optional 120mm in the front is for intake. I am planning to change the fans withthis 120mm and this this 80mm
is this the best way to have the fans set up having all exhaust except the one in the front intake or does anyone recommend having a different set up? thanks in advance

I vote for front and side because my side fan blows straight onto my northbridge which helps a me lot...I think.

I've built 5 this past year of different config, 2 water, 3 air cooled. If noise is not a consideration then best is 50/50 top- back out, side- front in for that case. For less noise use a baybus to control your fans, kill the top and back exhaust first, your psu should have a fan so you still have some forced exhast but most is simply positive pressure on the inside. Use a program like MBM to watch your temps and decide what is best for your situation.

well with the fans I wanna get I think I'm going to get a fan controller because they will get loud probably

if nosie is a concern, AVOID 80mm fan cases. try an antec p180 or 900 that use 120mm+ fans. those things will run quiet.

bump, if u guys vote please explain why

Well if you have a fan in front, you can often mount the HD's right behind the fan and keep them cool. Heat can kill the drives just as easily as the motherboard or processor or video card or RAM.

if you have more intake then there will be a negative pressure which spaces out the air particles more making the temperature lower, although this will pull dust in through all the little cracks it can get through so as evenly as possable would also be good.

I think im gonna put it front and side intake while top and back exhaust

i voted for side and front intake, and rear exsaust. my reasoning- 1. front intake cools HD's. 2. side intake cools gpu and chipset. 3. rear exsaust means not rear intake, which is bad cause hot psu air is right there.

also- def. make the top fan exsaust. this is known as a blow hole fan, and since hot air rises, its nice to have it blown out the top of the case, even if the psu takes care of most of it.

I use front intake and top/rear exhaust. Heat rises intakes are lower then exhaust. I let physics help out meaning i can run the fans lower = quieter Im a silent freak i need to get my vf-900 quieter now...
