HP dm4: Fan won't throttle down

Hi people looking for some help here. I bought a hp dm4-1046 at Comex and the exhaust fan is just stuck on high all the time. I've disabled the 'fan always on' setting in bios already and it hasn't changed anything. It's equally noisy after a minute of prime95 (coretemp ~75C) as it is when it's idling (~30C). Nothing appears in speedfan also and I can't find a way to manually throttle the fan myself. It's far too noisy to be normal and from what I've read online about the dm4 no one has reported such an issue before.

Has anyone experienced this before? I'd really appreciate any advice that you guys can give me. Thanks!

I have the same problem. It's causing my battery to drain pretty fast as well. It just started recently. I wonder if it might be due to a faulty sensor on the board. Did you ever find a way around it?
