Hi,

Is there a way of monitoring the rpms of the fan
If so, how fast should it be spinning
Thanks

You can use Speedfan to monitor your fans.

If so, how fast should it be spinning

This really depends on the PC manufacture, motherboard used, fan manufacture... and current temp of whatever device the fan is being used on. Most fans run in the 1000's of rpms... depending on which fan it is.

thanks for replying

in the speedfan window on the readings tab
it says:
fan1: 0rpm
fan2: 2500rpm
is fan2 the power supply fan or the cpu fan?

Fan 2 is usually either the CPU fan or a case fan.

It's not usually possible to monitor the RPMs of the power supply fan, but as long as its actually spinning and pulling hot air out, I shouldn't worry. Anyway the electronics are more likely to go first.

ok
it just that when i boot up the power supply fan spins really fast making a loud sound. then it slows down and gets quieter but is also changing speed (sound)
i suppose this is normal

Again... it depends on the manufacture. Did the PS do this from day one? You might contact the manufacture via email to query about it.

unfortunately the manufacture has gone bust
it was fine at the start but it seems to get worse
it seems really erratic and sometimes it takes ages to start
what happens if the fan suddenly stops?
if i do need to get a new fan, what would i be looking for (just need average fan but pretty quiet)

If the fan stops, the power supply will overheat and probably die. During that time, it could spike and also kill your system components. Not good!

I've never replaced a fan in a PS, I just go out and buy a new PS. I really can't recommend a fan because manufactures use different sizes and the fans may be spec'd differntly. I wouldn't know what to suggest you get. Some fans are also hard-wired internally, (soldered to the PS motherboard) so you would also have to own a soldering iron if you were to go in to change it.

Power supplies are a very important component in the system. If you buy cheap, then you can't expect them to perform for very long. The only thing I can recommend is you take a look at your system requirements then check Newegg.com and replace the entire PS so you don't have to worry about it. Newegg buyers leave a lot of good/bad feedback for the products they buy (myself included!). You should be able to get a good feel for which power supplies are popular and have good ratings. There are a ton of power supplies on Newegg... with varying price ranges... I'm sure you'll be able to find something suitable.

WARNING>>> If you own an OEM computer... ie, Dell... you may have to call the manufacture for a replacement PS. Manufactures like Dell use proprietory power supplies. The pin configurations are not the same and replacing a PS in a Dell with something off-the-self may kill your computer.
