Most Sony Vaio systems are pleasant and aesthetic. They come with well polished cases of glossy-looking finished works. That is one of the first things to notice about the products. Apart from that they usually come with good quality features and well equipped more often than average systems out there for corporate uses.

The major problem with them is *whizzing fan noise that disturbs when they multi-process information or pressure to run high GPU games, even at times they make much noise when they are not doing much works.
This fan noise can be reduced to barest minimum by anticipating some minor changes. You'll have to notice the noise often times before taking any action to apply these changes.
Before you go about the minor changes know that it is healthy for Sony Vaio system fans to make noise, but when they make noise often times than normal then it is not normal. There are rare cases of bad fan with loose spin which you might be required to purchase new one for a replacement.
The following step-by-step process will help in minimizing the disturbing noise.
Note: Before proceeding with this process it is required of you to have much idea about system hardware. If not, kindly take the system to your Sony Vaio Costumer Care Center and explain this process to them.

STEP 10: Cover it back and place the screws at their appropriate holes. Make sure they are tightened (not extremely tightened).
STEP 11: Start your system and the noise will become normal.
* The reason why some new Sony Vaio systems make much noise is due to the old nature of the thermal paste or has hardened loosing its cooling effect after long time in stock.
