Hi and welcome to the forum.

Some notebooks have noisy fans and some are very quiet, I never hear mine but I know that it is working because when the CPU temperature rises to 56 deg C it soon reduces to 54.

Download
MobileMeter and check out the CPU temperature.

If your CPU control is set to ‘Adaptive’ then you may very well be running at 800mhz until such time as more processing power is called for. Try playing a video and see if the speed increases to 1.7.

Which model Vaio do you have?

I have the

Sony Vaio VGN-FJ1S

I just have never seen the fan moving at all. Even when I boot up the fan does not move at all. How do I see what my cpu is set at. As the bios is nothing there it very basic

Right click the power/battery icon in the system tray and select Edit/Create Profiles…

Then look under System > CPU Control., for the profile that you are using. You will probably find that it is set to Adaptive which is the best setting for keeping temperatures down.

If your temperature is not rising above 58 I would guess that the fan is working. Run a few applications and monitor the temperature, it should rise and then reduce when the fan kicks in.

In that case all is working as it should. The processor fitted in your model has a critical temperature of 100c, but passive cooling will kick in before that (probably around 85C) and slow the processor in an attempt to reduce temperature.
