Fan on full all the time

Following my problems with the display freezing / going blue etc my local computer shop installed a new motherboard. All seems well except the fan seems to be running at full belt all the time and is very noisy whereas before it idled until the heat built up and switched to high only when necessary.

Is there a setting in control panel or similar that switches the fan to high/low intermittent under temperature control ?

Usually it's a setting in the BIOS that controls the fan speed.

Not all motherboards have fan speed control for the case fan, just on the processor cooler. I fitted one of these fan speed controllers and it lets you turn it down to the level you want. My AMD never gets warm even on the lowest speed.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Thanks guys.

It's the processor fan that thinks it's a Dyson.

Is the CPU fan plugged into the correct header on the mobo (probably labeled CPU fan)?

had a thing called speed fan (or fan speed?) on one of my old laptops because it always ran really hot. you can control the fan speed, and it tells you the temperatures of various bits. might be useful? its a free download i seem to remember

Thanks for suggestions. yes it's in the correct header. It's gone back to the shop to see if they can fix.
