Psu fan direction

post #1 of 9
Thread Starter 
So this may be a noob question, but I've never had a case that has the PSU on the bottom. I have this psu for my Haf X. Should I be placing the PSU with the fan face up or with the fan face down pulling air from the bottom? I wasn't planning on using the wheels for the case, as I almost never move my case. Would this ruin the airflow in the case?

Thanks

The fan should go face down to pull cool air up from under the case, otherwise you'll be pulling away cold air destined for your graphics cards.

Does the HAF X have any rubber feet if the wheels are taken off?

Don't really think so. I'll go ahead and keep the wheels on it. Even though I never move it, it will be worth it for the airflow.

As in there is almost no temperature difference?

As a note, there are also no dust filters on the bottom venting of the case.

Well I don't know what temperature difference there might be. I can tell you that people stress out way too much over their airflow. It's not like your PC has these tightly channeled flows of hot and cold air and such, like the people who diagram show it... You're more suggesting that air go in a particular direction. One fan in an out of the way corner of your case probably won't have much impact on the temperature of your major components no matter how it's oriented.

Thanks. Personally I had more wanted to face PSU fan up. Wasn't planning on using the wheels as it might not fit under my desk then. Also the lighting with the PSU will be nicer facing up. Just wanted to double check that it wouldn't cause some negative effects on the case.

Doesn't matter which orientation, either way it is pushing air out the grill. the only reason it would is if your PSU runs super hot, which is VERY VERY VERY BAD tongue.gif. People usually have them intake bottom orientated just so it isolates the PSU from the rest of the case and doesn't effect any temps or air pressure what so ever (negative=bad so it facing down doesn't lower the air pressure). My PSU is currently orientated facing up but I have x5 1850 rpm gentle typhoons on a controller so the air pressure is pretty easily adjusted.

If you are coming down to PSU orientation for temperatures, your issues are elsewhere. It won't make a noticable difference.
