[resolved] Zalman CNPS3100+ Air Direction

Stealth3si · 08-20-2005, 08:30 PM

I got this CPU cooler and an arctic cooling pro case fan and want to know what air direction is the best for the setup. So far, I have the case fan, located near the cpu, blowing air out towards the back of the case and the cpu fan blowing towards the cpu. Should it be away from the heatsink/cpu/mobo or towards it? Thank you.

Sounds right to me, the fan on top of the heatsink/cpu, blows down on
heatsink. Then you have a fan in the back of case underneath the power
supply sucking hot air out, right.? If you have a fan on the side cover,
I prefer to have that fan blowing in, on top of mobo/videocard/cpu.
But factory setups have that fan blowing out/exhaust for some reason.I
have tested mine and found I have better temps with the side fan blowing
inward.

That's right. I have case fan underneath power supply. I don't have a fan on the side cover or enough opening on the side to suck/blow in air into the case. So I plan to install a fan in front of the case to suck air in that blows air inside the case towards hard drives. Then the air will flow from that point to the cpu fan and then out to the back. Hopefully I will get some ventilation. Does that seem right?
