Fan at high speed, but not an overheating issue

Good Day,
I'm attempting to get an old Gateway XP desktop running again and the tower's fan is running at very high speed the moment I power it on, so it can't be an overheating issue. Anyway, I have the case open and the vents are clear, the fan free of dust. Where can I go to change the fan's speed through a setting manually? Oh, it is able to boot into the desktop BTW, but it only runs for about 10-15 before it actually does overheat and shuts down from the fan's over-working. Mods, I put this in CPU since it's clearly not a cooling problem. Thanks guys for your time.
 
Solution
What temperatures do you see when it is at the desktop, and in the BIOS? It is possible that the thermal paste is all dried up and is impacting thermal conductivity between the CPU and the Heatsink.
When you first power up system, generally all pumps and fans spin up to max speed and then "Chill out" and slow down once in Windows.

Stock Cooler ? See if it hasn't jarred loose.

Reseating or adding an inexpensive 3rd party cooler of you are going to go thru all that effort.

Yeah, it's powering up as usual with the high speed, and it never slows down. If it was purely overheating, it would need to run long enough to overheat, but it's running full bore even when it's ice cold. I'm thinking a fan setting?

Will do, I used Speedfan obviously and jacked up the settings which is why it won't slow down. I wonder if I uninstall it, if my fan will revert back to prior settings?

You called it on the nose, thanks so much. The second I pulled the heat sink, cleaned the dried up, cracked paste with alcohol and put new paste on, my PC ran as cool as a cucumber, not to mention running as quiet as it has in years. I didn't have thermal paste but white lithium grease worked perfectly and it doesn't break down until 393 F.
