Is it safe to use the PSU as another cooler

Hi forums,

I'm having trouble keeping my GPU cool. Mainly because I built the airflow so it could flow over all of my motherboard's heatsinks.
My PSU's right next to my GPU, is it okay to use the PSU as another fan?
Would it just be beginner's unguided idiocity? Or would it be crazy enough to work?

Power supplies as a case exhaust was common before, but most cases now allow for other cooling options.

It is still important to know that some power supplies can operate at temperatures upto 50c(maybe higher) and will just speed the fan up to compensate for any extra case heat.

It sounds like a SFF system so you may not be able to improve performance/temps much.

Here is my SFF and the power supply is an exhaust taking air right from the cpu fan(it blows air up and the power supply takes a good portion of it out.).

If you think outside the box, You may be able to perform some mods to get better cooling.

I would be interested in a picture of the inside of your case.

My case's airflow's kind of bad on the interior. The GPU is pressed right up against the PSU, and it's a AMD Radeon HD 7850 made by Powercolor. The wires don't play friendly with the case either. Hence why I need as much cooling as I need.

I'm using an Asus M5A97 R2.0 with an AMD FX 4350. I have it on the "bottom" of the two slots to allow the mobo heatsinks some air, as I've noticed those under the top slot get really hot.

I'm also using a Raidmax Cobra as my case. (You know, the one with the green interior, green LED front fan, black exterior, wide chassis because I keep cutting myself on narrow chassis) Also maxed out fans all pointed in the correct directions without custom mods.

I've had other issues with my computer as well, such as a few BSOD issues, moving the gpu did some good, but when my new PSU comes (another thread I made) I might be rearranging the interior a bit.

I would not expect heat issues in a fairly large case.

I would keep the video card up top especially if it is a open fan cooled instead of a blower type card.

The case has vents on the floor allowing the power supply to get outside air. This is the recommended configuration.

As for the chipset, they can get pretty warm without issues(You may be able to add a fan near it to help cool it while still having the video card in the top slot, but this would be more diy than anything since your case lacks a side panel fan mount.). You may have to check some other hardware for your BSOD issues(memory can be bad for this if not setup right or just defective.).

Just to confirm your case front fan is intake and the top/back are exhaust right?
