On boot up (after using the computer earlier in the evening) I got a message saying the CPU fan wasn't working *but* as soon as I disconnected my modem and restarted computer the computer is letting me post and look . I get no warning sounds, and it doesn't feel hot *at this moment* but I don't know where to look or turn to test to see if it is working using Windows 10.
I've had Nothing but problems since installing Windows 10. any suggestions for a computer newb to go & test my fan out other than a shop?

I have a rather peculiar problem on a windows 10 upgraded notebook:
The system consists of a VAIO SZ4 Laptop, Intel Core(2) 2,13 Ghz, 4BG Ram and SSD.
Every single time at cold system start, the CPU fan start going crazy, speeding up to maximum noise, rumbling and rattling and audibly overspeeding the fan bearings. Electrical substation handbook pdf.

After a few seconds (usually 30-60 seconds) when the system is fully up and operating, teh CPU fan calms down and runs at usual speed, with low noise and no significant audible distortions, even when high performance programs are run.

Nevertheless, because of the initial high speed uncontrolled run, I have the suspicion that the bearings of the fan will deteriorate soon and create addition running noise even during regular operation.
My investigations (with a HW low level fan control tool) indicate that windows 10 is maximizing the fan current until the mainboard is reporting valid data on CPU temperature and three other measuring points on the system board.

The fan control tool is displaying an unknown temperature at the measuring points at cold start and a few seconds after the mainboard reports valid temperature ranges, windows 10 is starting to level the fan down to reasonable speeds.
It is remarkable that this is only occuring with windows 10, I had before Windows 7 and Linux installed and neither of those displayed this behavior.
unfortunately, there is no way to control the fan speed in BIOS, so I need a specific solution for the OS, otherwise windows 10 will be kicked off this PC.
