CPU cooler air flow

Last response: in Systems

I'm building/upgrading a system for someone and wondering what the best way to point the cpu cooler was?
The cooler is a Arctic Cooling Freezer 7 Pro.
As I'm building in an existing case which has no case fan slots, front or back, am I best to point the airflow at the PSU?
The PSU has a 120mm fan which draws air out of the case which blows out of a grill at the back of the PSU.

Are there any potential problems from doing this?

nb. I'm aware that I may have to mod the case to add a fan, but only if i really have to. :)

You would be best served by putting in a rear exhaust case fan. 120mm if it will fit, and point the freezer 7 fan at it. Case modding can be time consuming, but it will be worth it in this case.

Thanks for the reply.

Yeah, you're probably right. I'll built and install, then run something like Everest to monitor the tempertures.
The case wont take a 120mm but I should be able to stick in a couple of 80mm fans, if necessary.

I finally got the system built and it ran nice and cool til I tried making the PC work hard with a test DVD encode. Tempertures were fine for system and CPU but the PWM sensor went sky high, which caused a shutdown.
One 80mm fitted to the back of the case solved the problem :)

Nicely done McPhisto. :-)

I know it's hardly rocket science but that was the first time I've had to alter a case to add a fan and with it not being my own case, I was nervous that I might make a mess of it. Fortunately it all worked out and next time I'll have no worries.
