CPU fan speed too high and too loud

You're very welcome, John.

That is great news to read.

Paul,

Any thoughts on why this happened in the first place?  Thinking back on things I'd noticed a few months back when I was running some games the fan would run a bit louder than normal but ultimately would slow back down again when I stopped with the games.  But now the fan runs like it did when the computer was brand new.  It is literally not possible to hear it even with the case open.  I can't believe it.  Well at least I learned how to use thermal paste.  I've done a lot of hardware installation over the years but have never dealt with a heatsink and CPU.  When I started with computers there was no such thing as a heat sink because the small CPUs never generated enough heat to need one.  My first computer was a Commodore 64 and we thought we went to heaven when I got my first 286.  Things sure have changed.  For all of your incredible help and kindness, a heartfelt thanks.

You're very welcome, John.

It is really hard to say what could have caused it. It is possible the processor heat sensor got stuck and clearing the CMOS fixed it.

I would also say that you must have done a bang-up job installing the processor, heat sink and thermal paste because of how nice and quiet the processor is running. That means there is an optimum heat transfer going on there.

I have done it a few times. I once put on too much electrically conductive paste and blew up my processor and motherboard. I have put on too little and it was running too hot, so I had to re-do.

I have also done it successfully several times as well. I wasn't a total klutz.

I started out with an Atari 800 and you could buy the optional BASIC language cartridge for it. I took a BASIC programming course in college, so I could write some elementary programs, but mostly I bought it to play Pac-Man, Space Invaders and Centipede . 

My first "real" PC was an old Acer with a 486/66 DX processor, 8 MB of memory, a 512 MB HDD and a 2x CD-ROM, Windows 3.1.

Once again, I am very happy that you were able to get your PC back to like new condition, for the price of some thermal compound, and a few gray hairs.

Paul, The gray hairs were there a long time ago.  If you ran 3.1 then you are too familiar with writing autoexec.bat files and config.sys.  I felt robbed when W95 came out.  It spoiled all the fun I used to have and ended my guru status among my friends.  I would have done a lot for a 486 man!  Take care and thanks once again.
