CPU Fan Failure Warning

[fxv300]

CPU Fail warning. Message appears at random times maybe once or twice a
week.
When this happens sometimes you get a chance to say ignore and it will carry
on working till you switch off.
Other times it just freezes, a reset and all is well ...went to the BIOS to
check temperature but at 40C nothing to worry about.

Why do I get a message when at the BIOS I have CPU Fail warning turned = off?
I don't think I was getting this message when I was running W7 64bit RC.
Have swapped CPU stock cooler with Arctic Cooler v7 rev 2
Also swapped 750W PSU with a brand new 850W.
Not using that much power to be honest.

Et6 from Gigabyte seems to make things worse.Various fan speeds have been
reported by ET6 so I have totally removed it from the system.
I have now turned off all FAN warnings including CoolNQuiet at the Bios but
the issue remains.
Also turned the Core voltage down from 1.35V to 1.25V ...same problem.
Have turned off all scrensavers and power saving utilities at the OS.
Any ideas would be welocme.

Run Speedfan and have it log everything. Fan speeds, temps, voltages, etc. Maybe something is happening under certain conditions to where it's causing that to happen.

You could alternatively put in a spare drive and reinstall windows to see if maybe if it's installed. Other things you can do while you're away is run Prime95 and Memtest to see if maybe it's your RAM or something else that's just incompatible in the lamest way.

I have another drive with a different OS on it, I will check to see any events in the event viewer. I have re-arranged the fans in my PC now and it is cooling better ...ie all rear fans =exhaust and front and side =intake. No crashes since 11th ...Thanks for the advice
