I have a HP Pavilion 8805 and when I start up the computer it says CPU Fan
failed system will shut down in 5 seconds, so I opened the case and the cpu
fan was not working which is a small 6cm by 6cm and 1cm thick. So I take out
the fan and tried in on another header in another computer's motherboard and
the fan is working ok, what would be the problem?

cheers
 
The copper traces that supply the header could be burned through, creating
an open connection = no power.

I plugged the fan back in and it started running but only for a few seconds
and stopped, turned the pc on again and same thing! so it's a motherboard
problem?
 
You could try plugging the fan into a different fan header. Please note
though that if the fan is drawing excessive current (defective) it could
burn out additional fan headers. Fans are cheaper than M/B's. Try a new fan
first.

Unfortunally I only have 2 fan headers on the M/B, 1 is the cpu fan and the
other is p/s fan
 
Do you really think it could be the cpu fan? it appears to be working ok on
another computer
 
Time to call HP and talk to India.

I brought a new fan today and everything is working fine now, strange how
this old fan worked ok in another computer.
Just one more thing, I noticed there is a cable with a 3 pin plug amongst
the power supply cabling, does this cable plug into the p/s fan header on
the motherboard? as it wasn't plugged into anything, or is it there for
monitoring?
 
On my Antec power supply that cable is for monitoring the power supply fan
speed. You need the requisite connector on the M/B. Not all have it, I
imagine.

Use the P/S_FAN header.
