I have seen some supposedly quiet PSU with 120 or 140 mm exhaust fans on the top side of the PSU. My case doesn't have exhaust holes at the top. There probably are cases that accommodate PSUs like these, but I can't remember seeing any. I guess I need to make some modifications to my case if I want to install one of these PSUs, does anyone have any good suggestions on how to proceed with this?

The big fans are on the bottom. That way, once it's mounted over top of the CPU, the heat will be
grabbed by the PSU fan, before it can spread around inside the case. Keep
the dremel away from your case for now. :wink: GL

OK, I just assumed that it was an exhaust fan because at least on some PSUs I've seen there is no fan in the back. I guess that would be OK though, cause a PSU is quite small, and the air would have no way to go except out the back grate.

yep those big fans suck air into the psu. the hot air exits out the back withouth the need of an additional 80mm fan.

although it wouldnt be a bad idea to have the large fan as an exhaust..... pitty cases dont come that way.

You wouldn't want one on the top blowing out anyway, all the dust & other $h!t can then go & settle in your power supply when it's off then.

If I got a quieter PSU my system would burn up. I'm externally liquid cooled (Zalman Resorator 1) and the only thing keeping the rest of the system cool is my 120mm power supply fan. It is quiet though.

If dust did fall into the PSU wouldnt the dust come out agan once the PSU starts up?

eg Lian Li PC 60 plus has a 92mm case fan on the top and it blows hot air out of the case. works quite well and it hasnt collected that much dust (3 months now).

Not all the dust will move & will build up over time, lots of places to catch in a PSU.
