Power supply fan facing side ? a problem ?

[northZephyr]

Hi
Just a little thing I noticed when completing my build :

THe power supply I chose Corsair 620HX Link

must fit in to the case I chose : Antec 900 Link

But the case offers a bottom-PSU socket... is there going to be a problem if I place the PSU upside down so the fan could face upward ? ('cause reading comments, many ppl say the fan is facing downward...

Thx

Turn the PSU "upside down" and magically the fan will face upward.

Exactly, unless the PSU is liquid cooled, gravity has no effect on it. 😉

Flip it around so the fan points up.

I'd rather cut a hole in the case below the PSU than turn it upside down.

why? Other than the logo being upside down it makes no difference.

Exactly. Why? So it can suck up dust bunnies off the floor?

The PSU would be sucking in cooler air since it wouldn't be sucking in off the graphics cards, but if you have a decent PSU it shouldn't make any difference to it's output capability or longevity if you have an appropriately sized PSU to begin with and case temps don't exceed 40°C.

Well that was my point in the matter. Maybe a full-blown hole is a bit too much but some smaller ones for the PSU to breath through. I clean my apartment pretty often 🙂

Has it been tested that it has no effect? I just thought that it MIGHT trap some air inside the PSU as the airflow isn't designed for the PSU to be upside down and the hot air would try to escape through the fan.

You using forced air to begin with, so the "hot air rises" theory doesn't apply. The air is going to push out the back with the fan up just like it would with the fan down.
