What is the best fan setup for a case

[SuperS2k]

Hey, I have a Nzxt Phantom case with the H100. My original setup was going to be:
2 Top case fans Intake The H100 would be under this with the fans blowing downwards as well.
2 Side case fans Intake
1 Front Case fan Intake
1 Rear Case fan Exhaust

Would it be better if i changed the Top case fan and the H100 for Exhaust rather then Intake?

Interesting question... was dealing with similar one lately (check my latest thread)...

My best guess/advice is try different setups! I was choosing before the top exhaust option, but it turned out that having an AC outlet over my pc makes it much better with H100 on top as intake...

So, it depends on multiple factors...

Generally the top fans are better as exhaust but this isn't always the case so as Zka said above try different setups and if your really concerned you could even look at different fans to put in.

you can attach like this or even with extra spacer. I use 2 200mm in the top as exhaust. 1 200mm in the side and 2 120mm in the side and a 140mm up front useing the fan controler built into the case. I mount mine outside like that to take all the bend out of the hoses and if the rad leaks or the hoses that go into the rad leaks it is outside the case. Of course if the waterblock/pump input/output leaks I'm up the creek.

Hey there!

This, as always, depends.....

It depends on the set up in your case, how freely air can flow in and out, cable management in the internal space, placement of internal case supports hdd cages etc.

If you have your fans as an intake for the radiator you will see better temps, since the cooler air is outside your case. However, this is in the ideal world where the flow into your case is not meeting positive pressure which will reduce the flow and the cooling efficiency. So to make the ideal world you could make both side fans exhausts and this would ballance intake and exhaust perfectly. This of course assumes free air flow within the case. At the end of the day each setup is different and a bit of experimentation will show you what your case likes.

At the moment your config would give a positive pressure case. Negative or neutral pressure cases are coolest. If you have a fan as an exhaust get rid of as much intermediate blocking as possible...i.e. remove dust filters. Dust will not get in through an exhaust fan and filters or plastic grills etc. reduce airflow.
