Placing of the fans - does it matter?

Recommended Posts

Does not have to go out. When you got a 230 at the top to get rid of it all, you fine.
It is still going out isn't it ? hahaha

I have mine blowing in and the case temps are probably still cooler cos it is blowing in over the radiator. There is still a 230mm for exhaust so ot may be different for you.
I good strategy is to have match in and out, i.e., have the same CFM blowing in at whatever you are trying to cool, plus an equivalent amount of fan cfm pulling air out of the case. This keeps pressure equal and makes the process more efficient. Noel EDIT: oops, been said already ;o)

A long time ago I decided to put a thru-the-wall air conditioner, a lil 8K BTU one, right behind my PC tower, in part for room cooling in summer, and in part as an experiment for PC cooling. I then created a ducting system w/ 4" metal flex hose that directs cooled air, when needed, directly over the CPU HSF, mainboard, GPU and DIMMS w/ the rear case cover off. Most of the time I only operate the A/C without a/c on now, i.e., I just have outside air coming in which is all I need for o'clocks up to 3.8 or so Ghz. When I was o'clocking to 4.2Ghz, I ran the A/C on (not just fan only) which kept core temps down to around 54C at peak load. Since I can get 3.8Ghz now w/ only 1.325v to the CPU, I don't need to run the A/C unit w/ cooling on--I just use air alone. I didn't see enough improvement at 4.2Ghz to warrant exposing my CPU to the kinds of voltage it took to run stable at, around 1.45v, even though as I say temps were still quite good. I killed a pricey QX9650 doing that!
