Hi,

I've slowly been getting parts for my new PC and I was wondering how I should arrange the fans in my case. I have never used a CPU water cooler before and I am now, and I read you should have the water cooler fan being an intake fan so it gets fresh, cool air over the radiator. I have a Corsair Carbide 500R case for my build and it's going to have 6 fans. 2 stock 120mm front fans, 1 stock 200mm side fan, The radiator fan replacing the rear fan and 2 120mm fans added to the top panel. I was thinking, since I read that the radiator fan should be intake, that I would arrange them as follows:

2 front fans intake
side fan intake
rear radiator fan intake
2 top fans exhaust

Would this be the ideal way to set up my fans? Thanks in advance for any advice you can provide.

My other specs for the computer are:

Windows 8 Pro
Intel 3670K CPU
Asus Z87-A Motherboard
16GB DDR3 2400MHZ Memory
500 GB Samsung SSD
2TB Toshiba HDD
Dual Geforce GTX 660s in SLI
Asus DGX Sound Card

That configuration might actually work nicely. Everything is coming in all sides but one, which is the exhaust. Just make sure to filter all intakes as best you can. If you can't find a suitable filter for the side fan, I would consider not using it, making the two top fans intakes, and the radiator an exhaust.

If you want to know why I'm leaning more on more intake than exhaust...
Spoiler: show
  • This creates more air pressure in the case than outside. This means every tiny hole in the case will blow out. This prevents dust from getting in. The opposite effect, while it draws in cool air from every hole, it also draws in more dust.
  • Because there's less dust able to get in, your case is effectively like a clean room. You'll find your parts less dusty over time. The only thing you have to remember is give the filters a cleaning once a month
  • Also because all the holes in the case are blowing out, there's no chance exhaust gasses can be inadvertently sucked back in.
  • Because there's more relative air volume in the case, you potentially have more air to work with.

I used to be concerned about airflow, but then I realized: parts that need airflow have something called a fan. The airflow produced by the fan is orders of magnitude higher than any natural airflow in the case.

Hi LatiosXT,

Thanks for your reply, you've been helping me quite a bit lately =)

How should I go about filtering the fans? Is there something I should use to put over them?

You can use that or get filters from FrozenCPU.com.
