Re: Need help..... my internal PC fan is extremely noisy
You right on the mark about finding the root cause instead of just changing the fan.
Its most likely the 2 things.
1) you're overheating, and could be a couple reasons. Most likely its dirty. You've probably not cleaned out the dust. Depending on the age, the thermal paste between cpu and fan could be dry.
2) You've been warm for awhile, and the fan is wearing out now.
So, as 95 said, use speedfan, or hardware monitor to check your temperatures, and open your case and check how dirty the fans are.
Thats step 1 and free.
