Hot Power Supply

[LarryXtreme]

I recently built a computer for a friend of mine. He tells me that the top-rear (power supply area) of the case is very hot. I also noticed the heat while I was testing it, but didn?t pay much attention to it since the system ran very stable. I put it through an 8-hour Burn-In test and I left it on for 2 weeks (with a few restarts). I also ripped some DVDs with it as well.

The case is made by Fudin, but I don?t remember the PSU brand. I am certain it is AMD approved. I believe it is Future Power. There are 2 front intake fans, and 1 rear exhaust fan, which is the PSU fan. Should he be alarmed that the power supply area of the case is hot? It is touchable for maybe 5-6 seconds. Again, the system itself runs rock solid.

I am going to send him a PCI slot cooler, which should release a respectable amount of heat from the case and video card, but I doubt it will have any effect on the power supply being so hot.

Any help is appreciated, thanks in advance.

Anyone?

Well I think power supplies are always going to be hot, but as long as there is a fan inside that is running you should be fine. It will always be hotter than an area of the case with no equipment though, no matter what kind of fan you have, so unless it's like blister-the-paint hot I wouldn't worry too much about it.

If the PSU is mounted at the upper rear of the case, make sure it is not mounted upside down. There should be no vents on the side of the PSU that is the UP side. All of the vent slots should be on the bottom, sides or rear (toward the drive bays) of the PSU. And, of course, make sure the PSU fan is working. If it is a variable speed fan the temp sensor may have failed, perhaps replacing with a one-speed or higher air flow fan would help.
