550D Fan Setup

post #1 of 5

Airflow Experts!

I am setting up a new case and trying to figure out the best fan positioning. The rig will be a 3570k+Hyper212 and a 780 classified as the main heat-producing components.

What I have to work with:
3x 120mm Cougar Vortex 1200rpm (non-pwn)
3x 120mm Corsair stock fans (af-120s?)

My plan so far is to have the Cougars as intakes in the front and bottom, with two of the corsair fans as exhaust at the top/rear. Not sure about the last corsair fan. Picture for reference, the yellow spots are the places I was unsure about.

The rear fan and the yellow fan on the HDD cages are optional.
if you can ghetto rig into the 5.25" bays, only do this if the bay slots are mesh, you can get replacement slot covers from some websites.

The AF 120s are not great fans at handling restriction, so only place them in places there there will not be stuff blocking their airflow.

mam72's layout looks good.
  • Intake in the 5.25" bays is always good for supplying CPU cooler.
  • Top intake may or may not help. Test and see.
  • Remove all unused PCI slot covers and grommets from back to exhaust airflow.
  • Raise case 30-40mm on blocks ( I use caster base) greatly improves bottom intake airflow.
You might find second link in my sig interesting.

Thanks guys, ill see if i can macgyver a fan into my unused optical bays. What about the side panel? My video card produces a LOT of heat and has a tendency to eat its own exhaust, would it be worth putting an intake/exhaust over it?

Also, would it be worth grabbing a few more cougars or some other fan brand to completely ditch the stock fans? (within reason, I'm not paying $20+ per fan)

With good intake fans and PCI slot covers removed the GPU exhaust should be pushed out side and back. I say should because air is a fickled witch and often does things we don't expect.

ehume here has a long thread about converting optical bays into intake vents.
