    I have a dv7t and it does the same thing. I have not figured out why nor a fix for it.

    Monitor the CPU load and temperature as there might be a process behind this.

    Yeah.. I pretty sure its the new nvidia driver. I rolled back to the driver that's still on HP's site. The one on windows update is also the newer nvidia driver as well. I'm not sure how nvidia managed to mess with the fan management on a graphics driver but there is no doubt about it, the new graphics driver does just that. If you installed the new driver from WU then that's probably what happened.

    So thats probably why my DV9774ca suddenly started to do pretty much the same thing a couple weeks ago. I had updated the nvidia driver and a couple other things, and the next day I notice that when I boot the laptop and its clap cold the fan will run full speed for a few minutes! It never did that before. It does that every day now. I also notice other odd on/off fan behaviour I never had before. Such as when just browsing on the net the fan will come on for a couple seconds and then off again, now and again. Drives me nuts wondering why it even bothered! I'm on Balanced in power settings and have not changed anything there, thats what was confusing me. And I was thinking my processor was overheating at boot up or something, causing the fan to come on full blast for several minutes.
    I might revert back to an older nvidia driver or wait for a newer one.

    Just go to the device manager and select roll back driver.. pretty easy to go back.. I think the fan management sucks on the new driver.
