I decided it was time to upgrade my dual core 1.8 GHz CPU and found one that is compatible with my HP motherboard. The unit was built in 2008 and can only take 4 GB RAM.
The new CPU is 3.0 GHz. I found it for $5 plus change on eBay.
I had to wait a few days for thermal paste as well.
The installation went smoothly. I removed the cooling fan and cleaned the old thermal paste off the cooling fan and old CPU with rubbing alcohol and cotton balls.
I replaced the CPU and added the new thermal paste, spreading it around evenly. There was no guesswork on the amount to use, as the paste came in individual packets. Very convenient.
I then put the cooling fan back on and everything looked right.
The system runs much smoother and faster now. It wasn't too terribly bad before, it was just starting to become noticeable that things weren't as quick nowadays.
My only complaint?
The cooling fan is much louder now. This was a quiet machine but now you know it's there. It could be worse though.

Cool, hope it works out, you'll know its a door stop or other use otherwise.
Last time I did a CPU upgrade was going from 33 to 66MHz.

That's when I got my 486DX which came with 66 MHz. I still have it. I don't know why lol. First CPU upgrade for me, but I did have to replace a CPU cooling fan like 22 years ago, so this would be the 2nd time dealing with thermal paste.

I couldn't find anything that was relevant in the BIOS unfortunately. The machine is HP Compaq from 2008. I did try this solution with fancontrol and eventually got the fan to chill out and act normal. askubuntu.com/questions/22108/how-to-control-fan-speedIt was close to 4300 rpm. A nice workout for it. It's now bouncing around 1600-1625 rpm which is much less distracting.

Yea, that is great tool. I know it. It should have option "on demand" to increase the fan rpm in case of higher performance and decrease on idle. Try to play with settings...

Yep, 1994. It was I believe a 486SX 33MHz, turned into 486DX 66MHz. But threw the computer away many many years ago.
Sounds like your upgrade went without a hitch, for the most part.

Stefan Apparently that's too much to ask, because that was my first thought, why not have a manual way of adjusting. Then I thought of this, adding a physical control and found this on a website. I might do this, because I can't find a way to lower the fan speed to 1400+ which is what it used to spin at. bit-tech.net/guides/modding/adding_fan_speed_control/1/

Be very careful!!! You can not decrease fan speed to very low value. Be aware you need to cool the CPU, lol! That's why I told you to search for "on demand" feature. When PC increases the performance, CPU needs more rpm and vice versa. Manual fan control is not the best idea...You can easily burn your CPU.

I'm just trying to get the CPU cooling fan to go slower, like at 1400 rpm. It's stuck at 1600+ which is 200 higher than before.
It would go to 1600+ before when needed but now it won't go any lower.
I can't find on demand feature for this software.

Trust me. It is a desktop cpu. I have tortured cpus with synthetic benchmarks, overclocked cpus... They all have survived. It is not easy to damage your cpu. Besides i believe after a temp or cpu state it takes control to protect itself by shutting down... These when i was younger and had some high end cpus. Nowadays with the help of bodhi and all software chosen i am in the opposite side. I am happy with as low as possible cpu usage...

I found a controller on Amazon that might do the trick. Looks interesting. www.amazon.com/Temperature-Control-Speed-Controller-Module/dp/B019P0FLHW I read that the voltage connector can be sensitive and I opened up the case and gave it a nice whoosh from the duster can and reinserted the connector to the pins, but it didn't change anything. I don't know if it's the sensor just not working right, or this CPU just demands more cooling even though it doesn't seem to really need it, or it's just a mixup with the BIOS. I don't care to put back in the old CPU just to test the fan. I don't want to deal with having to apply more thermal paste. I don't want to buy a new fan just to test since this one works. My older computers all have smaller fans and they wouldn't fit. Anyway I'd like to get it down to 1200-1300 under normal usage. It hovers a bit over 1600 as of now. That is the old rpm when I needed extra cooling. Now the lowest I can get it is 1600 using fancontrol software. First World Problems
