Blocked CPU Fans
There’s no such thing as a short cut when it comes to doing the job right. :
Is your laptop running hot? Is it burning your leg all the time?
Don’t ignore this as it indicates there is a bigger problem….
The cpu heatsink in a laptop will naturally get blocked after a period of time and will need to be cleaned out.
The ONLY way to clean a blocked cpu fan properly is to dismantle the laptop, remove the motherboard and the heat sink and then extract the fluff manually.
After the heatsink has been removed, the cpu fan removed and the dust and fluff cleaned away, then the thermal paste MUST be removed and replaced. The laptop is then reasembled and your machine now has a new lease on life.
Blowing into the heatsink with “a can of compressed air”, which may seem like a really clever way of cleaning the fan is actually dangerous and you run the greater risk of blocking the cpu fan as shown in the picture below. The result is that the fan just gets blocked up, stops spinning and that results in an overheating laptop cpu.
The next thing that happens is it goes “poof!!” and you end up blowing up the cpu or even worse the laptop motherboard.
Regular maintenance is the key here guys, once every year or so, bring it in and get it looked at properly.
Blocked CPU fans, get them cleaned properly.. It’s just a thought…
