How frequently to clean CPU heatsink ?

[Asaph]

hello everyone

Well, I wanna know how frequently should I clean the heatsink inside the CPU cabinet to keep my system well-maintained ?
Anyone any ideas ......

It completely depends upon the usage of the computer user.

Normally, the PCs used for the office purposes experiences heavy loads at times and are under continous processing. As a result, they need to be cleaned every 5-6 months atleast to maintain the performance.....

However, if you are using the PC for the personal/home use, then it's OK to clean-up once in a year.....

You just need to power down your system and dispatch the heatsink and clean it periodically....may be say once in every 6 months.
This will help your system to be protected from overheating and hence achieve performance maintainence.

Well, I had not cleaned any internal part of the cabinet from last 2 years.
Few days back, when I installed an additional hard-disk I noticed there was a considerable amount of dust accumulated on top of the vanes. I tried to cleaned it off with a stiff stencil brush and a tooth pick to clear out as much as I could from the vanes and set the vacuum cleaner nozzle on the job too. However, it is still far from completely clean.
