View Full Version : Problem with power supply fan

08-23-2002, 09:47 AM

I have an Athlon 1GHZ Box with 256 MB RAM and a 300 watts power supply.
Recently the fan of the power supply began to decrease its speed and
ended to stop completely.I open the power supply and i saw that the
components were fine..I disassemble the power fan to clean it out
all the dust.But it stills give me problems.It makes noise and i donīt
know why the power fan is failing..Do you know the reason?
I entered the BIOS and at the health monitor(An ASUS motherboard)
the voltages of the power supply are correct..The CPU fan also
is good..
Is it correct that the power fan throw out the cold air at the beginning and later as you use the PC,the air becomes a little hot?
Please i need advice..

Ok, first, is this a custom build or an off the shelf system?

Many of the cheaper power supplies use the cheapest fans possible and they are prone to the type of failure you are describing. You can replace the fan, but depending on what your power supply is, you may want to consider upgrading it.

Second, yes it is normal for the temperature of the air being exhausted for the PC to start cool and increase as you use it.

Probably the case of a fan with a
sleeve type bearing.

Good ball-bearing type fan will
last a looong time.
