One out the two rear fans on my HTPC started to make a lot of noise. As in really loud. This happens as soon as I turn the PC on and last for about 5 minutes and then the case is silent again. When I unscrew the fan and just have it dangling then there is no noise either but as soon as I screw it in the noise happens. It was working fine for about 9 months then all of a sudden happened one day. I've made sure the screws and really tight. Any suggestions?
Pl remove the fans. Use compressed air to clean the fans. Make sure that you hold the fan centeral area firmly so that fan blades won't move during cleaning. Once cleaned, install them again. Don't let dust accumulated on the fans particularly on the bearings.
My one SP-120 started making noise. After cleaning, no noise was there.
Ok I will give them a good clean and put it some rubbed washers. Thanks!
But if the bearings were gone or the fan was dusty then when doesnt it make any noise as soon as i unscrew it from the case? Strange..
Thanks easylover and everyone else! it seemed to be a dirty fan. Cleaned and no no more noise!
Now I have another problem When I put everything back together the pc starts for a few seconds then dies for a few seconds and then continues to start but theres nothing on the monitor. Ive created a new thread about this problem.
