I have an Asus P5S800VM motherboard with Intel processor.
It has just recently started booting to a warning that requires "F1" to
continue.
The warning is "CPU Fan Error! Press F1 to resume".
When I look in the BIOS the fan speed is shown in RED at around 1650 RPM.
I am thinking this is too low.
How can this be fixed?
regards
PeterH

It all depends of the fan you mounted on the CPU. Up to recently, normal
spin speeds were minimum 2000 rpm; however, some "silent" fans like Zalman
are spinning at very low speeds like 800 to 1200 rpm. When booting, the bios
detects this as a fan failure and gives you the warning. Sometimes, an
upgrade of the bios might help. Otherwise, you have to disable the warning
in the bios, or live with the warning.
If you have a stock Intel cooler, 1650 rpm is indeed too low and you should
check the fan.

Fan's failing. Common problem with
crappy sleeve-bearing fans supplied as
original equipment.

Clean the fan and heatsink, and/or replace or get replaced the fan and
heatsink..

....a squirt of WD40 lubricant on the fan spindle can help as well.

Jerry

This might be a little safer to use..

but will eat up the circuitry inside. WD-40 contains
some pretty damaging solvents. Which can be flung all
over the inside of your computer by whirling fan blades.

If you really want to overhaul a fan, you need to take
it apart, clean it up, lube the shaft and bearings with a very
small amt. of white lithium grease.

But you're just postponing the inevitable ;-)

Could this also account for the PC wanting to reboot occasionally after
opening as far as the desktop.
Although this seemed to only happen after installing Trend Micro PC-Cillin
anti-virus software.
Without PC-Cillin installed it seemed OK.
Could be a different issue?

No, WD40 is not a lubricant and is a short-term fix at most.

No, that is another inappropriate product.
There is no spray lube that should be used on fans.
There is no low-viscosity lube that should be used on fans.
There is no spray cleaner that should be used on fans.

The correct lube for a worn fan is very high viscosity oil
applied in non-aerosol manner (drip, applicator, or syringe
are typical methods).
