Noisey fan?

Im assuming that this is my fan that all of a sudden just started from its quietness to this horendous loud noise it goes on and off and on and off constantly. I guess its the fan I could be wrong but does this mean it needs replaced? I have had it a little less that a year now. And it just started doing this a couple days ago.

 

Find/Fix the fan

It sounds like a fan. Take the cover off of your case and power it up. Listen around until you find the right one.

If it's a case fan:
Case fans are standard sizes, remove the fan and measure it (in mm), buy a replacement.

If it was the CPU fan:
You'll probably have to replace the entire CPU cooler, might want to try to fix the fan instead.

If it was the PSU fan:
You may need to take apart your PSU to get the fan out. Be careful, there are components in there that hold a charge despite the unit being unplugged. Some PSUs are riveted shut, so you may need to replace the whole unit just to fix the fan.

If you don't want to buy a new fan, PSU or CPU cooler, try this:
Take the fan out of the case and use a "can of air ", or a powerful blast of air from an air compressor and hit every nook and cranny. Then try this:

The article explains how to use sewing machine oil to silence a fan. I've found it works great at repairing broken fans. I have 8 case fans that have all needed that treatment at one time or another and it's worked every time.

Hope that helps!

 

Yes its a dektop. As far as taking the cover off that wont happen LOL. I will just have to take it somewhere to be done. I know nothing about them at all well hardware that is.

 

Do you have any computer knowledgeable friends? It might just need cleaning the dust out.

 

No unfortunately I dont. I will just have to take it in to a shop to be fixed.

 

There are many low quality fans these days to cut cost. If its the sound of fan spinning fast to compensate for temperature increase, cleaning the heatsink can help, but if it's the bearing, you have no option but to replace the fan.

Adding a drop of lube may help if you can get it to the bearing, but it's only a band-aid fix.

 

Check if there is a disk in the CD/DVD drive. The disk could be out of balance or the DVD drive has become loose and is vibrating the panels.

 

Nope no disc in there. I never even have used it but once or twice. I think it is the fan cause if I shut it down at night when it starts up it makes no noise what so ever untill I click on IE then it starts it vrooming LOL.
