GPU fan speed set too high on system startup

[ralph09]

Hey guys,

I'm finding at the moment that everytime I startup my system, the GPU fan spins continuously at 50%, or about 3100 rpm. This is quite noisy and it's always previously idled at 30%.

My main suspicion for the cause of this problem is Speed Fan 4.45, which I had installed recently and looked at the fan speeds while diagnosing a problem with the CPU. I typed in different speeds for the GPU fan to spin but didn't set any rules or anything. I've tried uninstalling and nothing changed, so for now I'm stuck with running Speed Fan on each startup to manually set the fan speed to lower.

Another possible cause could be I recently updated video driver, now have AMD Vision Engine Control Centre, but haven't changed any settings in this.

If you have any ideas of how to resolve this, or places to go to ask the question, I'd love to hear them.

For some AMD cards the driver can have higher fanspeed as default profile. Take my 5850 for example I think it is 55%. I use MSI Afterburner to set custom fanspeed profile, so the fanspeed will go up and down according to the temp.

It seems quite a big change to my two and a half year old 4890 to suddenly increase the idle fan speed by 1500 rpm with a new video driver! Do you think this is an intentional change?

What are your idle temps like on the card?

Do you know if they've gone up recently - as they could be high enough to kick in the next incremental fan speed for cooling. If so perhaps your card needs a dust off.

Also, there's a chance that the new drivers have a lower temp tolerence before the fan speed ups for cooling.

If your temps are OK i would set a up your own profiles via ATi CCC or similar.
