Need Fan Config Advice

post #1 of 4
Thread Starter 
I've decided I want to turn my intel e2180 into my gaming machine.
I'm using the Antec 900 Case.

I'm going to start off by changing the heatsink to a scythe Mugen (right now it's a tuniq tower). The scythe has the capability to attach a 120mm fan to any side of the heat sink. I'm thinking I could put a 110CFM fan on the bottom blowing up towards the 200mm fan on the top of the case.

Another idea I had was to have 3 fans total on the heatsink. One on the front blowing towards the back, one on the back blowing towards the front (both 78CFM), and then the 110CFM on the bottom blowing all that air towards the top. I don't know if this would be too much for the heatsink to expel or not?

Heat is the limiting factor right now in my intel overclock so I'm hoping swapping the heatsink will help me out, especially with the advanced cooling of the antec 900.

Only one fan (two optional) is needed for a CPU heatsink. It's best to keep air flowing in the same direction, with the exception of the top exhaust fan. Having 3 fans on the heatsink would be useless, 2 would work, but the 3rd would mess up the airflow of the other two.



You could either run 1 or 2. If you use 1, use the fan on the right side of the CPU heatsink, so air is being blown through the fins.

Why would you not use the Tuniq? Great cooler. As far as the A900 goes it is great for cooling. If you want to lower your ambient work on your cable management. For your cooler the best thing would be a single 120 with over 100 cfm.

The A900 is already set-up great fan wise. You want a continuous stream from front to back and upwards. The other thing to keep in mind is how pressurized your case is. If you have more air intake, than your case won't be as cool but will be cleaner. If you have more air going out, than you are dissipating more heat inside. The best set-up is to find a balance between intake/outtake and keeping the air moving in the same direction.

so what should i do with the side fan?

right now my power supply sucks air out the bottom of the case, i have the stock 78cfm dual 120mms in the front, an additional 78CFM 120 in the middle case spot, as well as one on the back. plus the obvious 200mm fan on the top.

the heatsink is using a scythe 110CFM and the heatsink is lapped. I'm just thinking the scythe mugen may be better if i were to have the air intake on the side with a 110CFM blowing up to the top 200mm

i could still have the front and back fans as intake and exhaust, but the heatsink airflow would be going straight up towards the hugest exhaust point in the entire case..

no?
