If you have been using Desktop, Laptop or Note computer for quite some time, you notice some noise coming from internal cooling fan area.  Worst case scenario is the internal cooling fan completely stopped turning. You can clean the fan yourself or asking local computer repair person for the job.  Most of the cases, your cooling fan does not have to be replaced as it’s a rather low tech parts comparing with other sophisticated parts in your computer.  If you require internal cooling fan cleaning service (Sydney CBD, Sydney North Shore – particularly in Chatswood, Roseville, Lindfield, Killara, Gordon, Pymble, Turramurra, Wahroonga, Warrawee, Hornsby, Macquarie Park and St Ives area) please contact Harry 0417 424 909.  Or refer to our Service page.

Having appropriate air flow inside of your computer system is very important as heat is the worst enemy of your favourite computer which shortens your computer life.

There are many “How to clean and revive internal cooling fan” articles and videos available.  But 90% of the time, they are doing one thing wrong.

Application of Lubricant is not right.  Most of them use ordinary grease or quick lubricant spray which are not suited for Plastic component for the fan.

Ordinary grease or spray may damage the plastic.  It’s best to use Silicone Base Grease.

Unfortunately, Silicone Base Grease is hard to get in Australia.  Most of hardware stores, electrical stores do not have them in stock.  I use Sil-Glyde made in the US.  (As to specifications, please refer to the last section of this article)

Desktop type computer internal fan cleaning is relatively easy.  Please refer below images for my main desktop PC internal cooling fan cleaning process.

Fig 1 Main exhaust fan attached to back of my main PC running 24/7 (Brushless Fan).  Carefully peel the back seal (to be reused), take out plastic washer (you need 2 flat head screw drivers – it may take some time and please be careful as it may fly away if you use too much force to remove it.  Also, remove underneath very small O-Ring)

That’s it!  Now put it back and your internal fan works as normal again.

Below images are internal fans of Laptop computers.  You need extreme caution removing the fan as you have to remove other very important parts, cables etc. first to get to it.    Best ask your local computer repair person to do the job.  If you do anything wrong in process, your laptop or note computer may not be able to turn on again.
