I've just bought 3 120mm fans, two to replace the fans that were already on the case, and an extra to mount on the top in the special bay that the case has.

So I now have an intake at the front bottom in front of four hard disks, and two exhaust, one behind the CPU tower cooler (both blowing out, so my 2600k idles at 30-35 and peaks at about 75), and I've set the top fan to exhaust as well.

When running stress tests I am getting a decent amount of heat out the back, but none out of the top (it is spinning, rpm monitoring from mobo confirms this). So I'm wondering-would I be better off switching it to blow in?

Finally, the two fans I replaced do still work, so I've considered mounting one on the very bottom, to suck air up into the case to get more cool air in. Its easier than cutting the side grill to mount it as a crossflow; apart from the potential dust factor (can be mitigated with a dust filter).

Is this fan-setup a good idea?

you could try flipping the top fan to help with the circulation of wind :) – Shakehar Jul 10 '11 at 19:04
Yeah I'm thinking it wont to do any harm if no heat is coming out now! I'll stay away from the curry tho ;) – Andras Zoltan Jul 10 '11 at 19:08
Why does your CPU peak so high? What frequency/voltage are you at? (your idle temps are fine). General rule of thumb, looking at the case from the front (where the 5.25" drive bays are), intake fans on the front/left/bottom, exhaust on the right/top/back. – Breakthrough Jul 11 '11 at 10:23
@Breakthrough - Good question about the CPU peak (and part of the reason for the question). I'm running the 2600k with a turbo speed of 4.5Ghz with medium Load-Line-Calibration on my P8P67 Deluxe mobo. CPU-z tells me that at peak speed the voltage is something like 1.325v (from memory). It's certainly not above 1.4. If I run normal speed it gets up to about 65c – Andras Zoltan Jul 11 '11 at 11:53
