Fan troubles!

i am planning a new pc build in a few months and my case is a Bitfenix Merc Alpha, a Corsair 600W Gamer Series and 5 NZXT FZ120 case fans.
My problem is im not sure how to connect all 5 fans into the 4 pin socket on the motherboard (Gigabyte Z87M-D3H Intel Z87).

Please i need help!!!! :confused:
 
Either use a fan controller with the available hookups or you will have to use adapters if needed to hook up to the psu.
 
Also, some motherboards have a 3 pin connector for 1 other fan besides the CPU fan. You can keep that in mind when running fans.

Question: Why so many fans? Are you planning on having a lot of hard drives in there or something that generates a lot of heat? If you get a PCI-E GPU that will have its own way of getting rid of its own heat out the back. I don't see how you're going to fit that many fans at 120mm in that case.

You're going to need to make sure that you have an equal constant flow of air with no stale air within the case. With 5 case fans I don't see how you're going to maintain that.

I would assume he means that the OP's case would have to have equal inflow and outflow of air, but I feel like that wouldn't be a problem as long as two fans are blowing air out while the other three are blowing air in. I would also think that the two fans blowing air out should probably be the two on the top.

Nonetheless, to the OP: you would probably spend the least amount of money by just buying a few Molex Power to Fan Connector adapters. However, with this configuration, you would not be able to monitor your fan speed.

Well if thats the case its incorrect.

You either have positive or negative pressure based air cooling in a case - but never equal.

Positive pressure means more fans push air in, this is less effective than negative pressure (where more fans push air out), but has the benefit of less dust problems.

Never equal though. Negative or positive, depending on the environment it sits in. In a clean environment, you want negative pressure (more fans sucking out air).

Good to know. :good: I personally have a DIYPC "caseless" case, so I guess maybe I technically have equal pressure. :P

There ya go, I just never knew the exact way to put it. My bad for saying equal. I always heard that having a continuous air flow was good, but never had heard of the negative effect that you stated. That's good to know that it causes less dust though. Even though it probably wouldn't help in my case as I keep the side off of my case.
 
Just to be clear, negative pressure increases dust but improves cooling performance, positive is the other way around...
