My laptop has been getting a bit warm and the fan was always running and blasting out hot air. I recently opened it up and hoovered out a fair bit of dust. Now it is always running but blowing out cold air. I was hoping now it is running cooler that it would throttle back a bit as it is a bit noisy. A bit of googling suggests this might be something to do with a recent upgrade to Windows 10 but I've tried reinstalling Lenovo drivers and nothing has changed. Any ideas where to look?

Have a look in the task manager at what is running - Windows has this process that goes round rebuilding assemblies after an upgrade in suppossed 'idle' time.
How long has it been running with a high fan activity now it is cold air?
A couple of weeks.How long has it been running with a high fan activity now it is cold air?
It is a lot cooler than it was (ie room temp rather than hair drier) so I'm thinking software rather than still blocked.
I have been shutting down every process I can find. The fan starts slow on power up but as soon as the windows boot screen comes up it kicks into high and stays there.
Got the same thing and tried task manager as well as procmon in case there is something hiding itself. Not a sausage. It's very annoying but its not showing itself easily. Im guessing that there may be done thresholds where the fan kicks in that have changed but I've not heard the time to track them down yet
Interesting... could coincide with my fault. I'm running 64bit Win10.
of course there's always the possibility of a hardware fault - it *could* be the temperature sensor.
Would that be on the motherboard?
er. maybe. I've not fiddled with that sort of thing in windows for many years but I'd guess you need something like this -

Let the laptop get properly cool overnight and see what readings you get at start up and after a short while.
My little used laptop started bugging me as the fan was always running. Task manager showed the svchost.exe running at some 40%. I did an event viewer log dump and the fans now off and running silent again.
