Having problems with your Sony CPU FAN CPU Fan ?

My sony laptop computer has big noise when the fan start.

Answers :

Hi there,

It is normal for the computer to do this. When an application you are\015\012running makes greater use of the CPU, memory, video card, and disk\015\012drives, power consumption increases, and the fan either kicks up in\015\012speed or turns on. If the sound is annoying, you may be able to\015\012reduce the fan cycles by cleaning the dust out of the computer case.
\015\012Get a can or two of Dust-Air or a similar product.
\015\012Open the case of your computer by removing the screws on the back. Some\015\012computer cases have easy-open latches, so you may not need tools. Use\015\012a vacuum cleaner to get the bigger dust bunnies out of the case, then\015\012use the Dust-air to blow out all of the nooks and crannies. Make sure\015\012to blow out the heat sink for the CPU; the vanes tend to clog with\015\012dust. Blow off the vanes of all the cooling fans, too. There will be\015\012one on the CPU, and probably a few others, e.g., most video cards have\015\012their own fans and heat sinks now.
\015\012Replacing the case fan with a quieter model, such as a Vantec, can also help:
Computer makers build systems with the\015\012cheapest parts they can get their hands on, and if you're handy, it's\015\012worthwhile upgrading.

Warm regards,
