OT: Computer power supply on its side?...

[John Doe]

My PSU has an \"economy mode\" that turns off the fan most of the time the
computer is barely being used (you know, like posting to USENET).

However, naturally the design assumes it will be right side up. Does
having it on its side and allowing the fan to stop present any
overheating hazard to components? Of course normally heat rises.

I just cleaned it out. You know how dirty stuff gets when a fan is
running 24/7. My GPU fans turn off when the system is idle most of the
time. Would be nice for the PSU fan to be off during most of the time
too.

Thanks.

I thought most computers were designed to do that as the fan is
thermostatically controlled. If the circuitry isn\'t generating heat, why
should the fan be on anyway?

I doubt it would make any difference provided you keep all ventilation
slots clear. Although usually seen upright, I have seen lots of boxes
kept on their sides without problem for many years.

I just cleaned it out. You know how dirty stuff gets when a fan is
running 24/7. My GPU fans turn off when the system is idle most of the
time. Would be nice for the PSU fan to be off during most of the time

It doesn\'t even have to run 24/7. Fans and ventilation channels
eventually get filled with crud even if the fan is on very intermittently.

There aren\'t any vents for convection on the top side of any ATX power
supply I\'ve ever seen, if it\'s running high-power it expects forced air
front to back.

They\'re often mounted sideways in compact ATX enclosures as you can see
here:

So nah I don\'t expect it expects any particular orientation when it\'s
low-power enough to shut down the fan. Not the same situation as what
I\'ve heard about some LCD and plasma displays that expect convection in
the vertical orientation and may overheat when mounted horizontally.
