I was wondering if someone could help me with the following computer issue:
My wife has a Compaq Pressario V2000 that has always had a small issue with the fan. Due to some design flaw, the heat sink clogs with dust every 6 months or so. One can tell when it gets clogged because the fan runs at high speed non-stop. This is not the problem, I just take out the fan and heat sink and blow it out with some compressed air.
The problem is that this time, after doing this process, the fan now is rather loud. Sometimes it quiets down, but it is usually quite loud. I ran a temperature monitoring program and it shows that the CPU temp is fine (also the fan does shut off). I can't seem to find any program that will show the actual fan speed.
I have never had first row seats to the death of a fan.
Does this seem like the fan is going or is it something else?
Thanks for any replies.

I don't know much about CPU fans but unusally loud normally means bad bearings in most fan motors. The only thing I'd look for is something else vibrating that is mimicing a fan sound. Just my 2 cents...

Have you looked at the fan since you've replaced it... A fan getting "louder" can be a wire that strayed too close to the blades and is rubbing... Happens all the time :) Quite annoying too!
If there's nothing touching the fan/blades, then it's probably the bearings or brushes burning out, and it's time for a new fan :)

If you put any pressure on the sleeve bearings when you cleaned it, assuming it has sleeve bearings, that can cause the noise and the eventual death of the fan. I would try to find a new fan.

"I just take out the fan and heat sink and blow it out with some compressed air."
Common mistake. This overspeeds fans and ruins bushings and bearings.
If you have to blow one out, keep it from spinning.

+1 to that. I blew out a fan with compressed air on a power supply once, it spun so fast one of the fan blades flew off :O

Yeah, if I forget to do that, my fan spins like crazy. =D

Thanks for all the inputs.
There was a misspeak on my part.
I take out the fan and heat sink, seperate them, and blow out the heat sink. They come out together but seperate easily. I never blow out the fan.

Replace it.

Speedfan:

It shows fan RPM, temps, voltages, etc.

And S.M.A.R.T hard drive info!!! definitely a great tool, and it's free.

I tried that one earlier today, for whatever reason, it only shows the temp on her computer and no other data.

Sounds like your settings are off somewhere in the program.
I run SpeedFan on all 7 computers in this house, including two Dell notebooks.
They all show fan RPM, and for the big IBM workstations, that's 5 separate fans being monitored each.
It gets to be a pretty busy display:
