P182 Top fan which way
I took out the took fan in my antec p182 case and replaced it with a better fan. Now I forgot which way it was going. Do I put the fan in so it blows air down towards the cpu or do I put it up so it blows air up and out? I also have a rear exhaust fan as well. I want lower cpu temps so what would be the best way to place it?
Thanks
Thanks

try both?
pushing in may bring in fresh air and help lower cpu temps--but could be very dusty
pulling out may help reduce cpu temps if there is heat build up at the top of your case
Everyone's configuration is different, so you just have to test it yourself. Looking at the p182, at stock, the top fan is used as exhaust.
Hope this helps

Thats abit strange isn't it? I wonder why it is louder going in. How much cooler is it? I guess you will have to balance between cooling performance and noise.
Here is another idea: why not try using the rear exhaust fan as an intake fan to feed your heatsink, and then have the top fan as an exhaust fan to pull the heat from the heatsink? This may work better and may reduce both noise and temps!

This really depends on how much power your CPU draws.
If you have an old Pentium 4 (or worse yet a Pentium D), then you will see noticeable temperature differences with various fan orientations. For example, with a Ninja on a P4, having one of the fans blow in reduces the CPU temperature significantly, and raises the system temperature only a little.
On the other hand, if you have a more efficient CPU (Athlon or C2D), it is best to have both fans blowing out (or else just using one fan), and turning the RPMs way down.
EDIT: Hmph. Just saw your signature, which says C2D. Unless your system is quite exotic like mine, you will get very good cooling and low noise with the rear fan blowing out, and the top fan removed and its hole blocked off.

I imagine it might be caused by either the grill (or the "spoiler") being too restrictive for the amount of airflow.derekchinese wrote:Thats abit strange isn't it? I wonder why it is louder going in. How much cooler is it?
Or maybe it's some bearing issue?
I was under the impression that fighting convection like that is a bad idea - I would expect the case temps to rise over time...
