PSU blowing hot air into case

post #1 of 39
Thread Starter 
Hey guys its my first time starting a thread so please be patient with me smile.gif

I have a problem with my PSU and Antec 900 case.
The way the case is designed is a little silly. I have nowhere for the PSU hot air to escape, except for straight into my GPU. The PSU is at the bottom of my case with the fan facing upwards. The case does not have an opening at the bottom for the fan since it sits flat onto the ground.
The only way for me to re-direct this hot air is to somehow cut an opening below the PSU and raise the tower.
Does anyone have a better suggestion?
I will post pics soon

Get airflow and it shouldn't matter, not like it does now.

Well, if you can't figure out how to put intake fan in the front and one blowing air from case in the back slot you shouldn't try to cut your case.

Already have that set-up. The problem is my PSU is right against my GPU. The air doesn't have time to get sucked out.. I also have water cooling on my GPU and VRM's a little exposed. Is this ok?? I will have to take some pics and show you what I mean, its kinda hard to explain tongue.gif

I cut a hole in the bottom of my 900 for the psu and it dropped case temperatures slightly.

That is my plan also Evil Genius but my case sits flat on the ground.... there would be no place for the air to go. Is this going to stuff up my PSU?
I'm thinking of making something at work to raise the case and give the fan some space

Most power supplies blow air outside of your case through the rear vent. Do you have a picture of the power supply?

Just because the vent is facing upwards doesnt mean air is being exhausted into the computer. You have to look at the fan blades to determine direction of flow if not indicated otherwise.

what power supply do you have?

If your fan is oriented like this (note the angle/rake of the blades):


it is intaking air from the fan grill and pushing it out the back.

My 900 had feet on the bottom.

The psu would originally take hot air from the case and exhaust it but now it is much more efficient to have it draw cool air from outside.
