CPU Fan Error but Fan is Working + Increase in Temps

Steves1982 · 10 Jan 2011 at 21:02

This problem doesn't need solving as such as I'm building a new rig soon so I'm not too worried, just curious.

Recently when I have been booting my machine I have been getting a CPU fan error message now and again. However the cooler fan is running as are all the fans on my machine so not sure why I'm getting the error.

Funnily enough (or not) my idle CPU temps are up 8-10 degrees C. It normally idles at between about 28-30 and now I'm getting 40C in realtemp and 45C in core temp (not sure which is most reliable).

Any suggestions?

your fan could be on its way out. download fanspeed see what its doing

it's also not the ice age outside anymore

Ok thanks, will have a look using fanspeed.

It's the ice age in my house, the heating is broken!

The fanspeed is reading as 2458 RPM and it's rated at up to 2500 so that seems to be ok.

I always use to get the CPU fan error on cold boots. But my mate gave me this since I was setting up a pull-push configuration on my cooler and it seemed to have solved it. Might be the Asus board just not giving it enough power on boot.

As for the temperature rise, have you tried cleaning your CPU cooler? Could be dust buildup.

Yeah, I gave it a clean a couple of weeks ago when I installed my 6950.

I'm probably going give this pc to a friend when I get my new one anyway (minus the GPU) so will try the fan splitter then. If not he'll have to live with it, it is free after all!

Ah, so you also recently installed a new GPU. I would try out your old GPU and check your CPU temps. Sounds like it could be heat rising from the 6950!

I don't think so. Iit was idling at 30 a few days ago even with the new GPU. Plus my old GPU was a 4870x2 which was a heat monster (idled at 72C) so if anything I would have thought temps may drop a degree or 2?!
