CPU Fan speed error

[luke]

On boot-up I get beebs with an " CPU Fan error" & have to click on "F1" to continou booting.

"Real Temp" sudenly shows 30c instead of 23-25 degsC it used to show.

I reinserted the Fan cable & fan spins freely.

Any Ideas about this?

Use PC ProbeII & Real Temp.

Upgraded mobo upwards 16 Sept 08.

The fan error comes up 10 secs during post in bootup.

Pluged the fan cable to another socket on mobo too.

Fan speed shown as Zero although spins fast & follows Q Fan settings.

Fan speed threshold 600.

Real Temp Tmax was 95 & I set it 100
