CPU fan problem?

[Reyaz123]

Ever since I cleaned out my laptop fan with compressed air, my CPU fan is making very loud noises and shuts my power off. I check my temperatures for my CPU and mothererboard and they seem to be fine (49 Celsius or lower). However, my CPU fan runs at speeds over 4900 rpm. What is my problem, and how can I fix it?

Note:I sprayed the compressed air too hard in the fan and it may be damaged?

Replace the fan. Couldn't you use a vacuum cleaner to clean it?

I found out that i didn't need to replace the fan. The fan was not screwed in tighly enough with the heat sink
