In this tutorial I will show you how to fix a seized computer fan. All fans, especially cheap ones, will eventually slow down or seize sooner or later. This is definitely true of case fans that are never clean regularly. The case fan is a fairly simple piece of hardware and as a result it a pretty easy fix. The hardest part is sometimes getting the fan out of the computer case, but after that it’s straight forward to bring a fan back to life. The purpose of the case fan is to keep the computer hardware cool by blowing out the hot air from the case. This method of cooling is very effective and a great idea if you want to preserve the life of your system. If you notice that your fan is not running smoothly or not rotating at all then the lubrication in the bearing has burnt off so you need to add some more to get it working again. I’ll show you how.


Steps:

1. Before getting started you’ll need some general purpose lubricating oil and a utility knife or pointy tool. Any hardware store or big box store carries these items.

2. Remove the faulty fan from your computer case and unplug it from the power supply or motherboard.

3. Next, place the fan with the stick side facing up

4. Now use a utility knife or point tool and gently peel back the sticker until you see the bearing cover. Do not peel back the sticker all the way as you’ll need to put the sticker back after the repair.

5. Remove the bearing cover and pour a tiny amount of lubrication onto the bearing and manually rotate the fan to allow the lubrication to permeate all the areas.

6. After pouring sound lube on the fan bearing replace the cover and the sticker and then plug your fan into your power supply or motherboard. Now turn on your computer.

7. Let the fan run for a few minutes and then shutdown your computer.

8. Screw the computer fan back into the case and your done.

Tips:

– Try not to get any oil on the fan sticker as it will remove the stickiness of the sticker and you won’t be able to re-apply the stick to the fan.
