[SOLVED] How to slow CPU and system fan

[sutho]

Hi there I have resurrected an old computer this year in preparation for my first build of my own. The issue I have is I need to know how to access the bios or other system to slow the fans or reset the CPU temperature. The computer I have fixed is a rather old one (I plan to connect it to a smart TV for kids to watch their movies on the screen only, it will not be connected to the internet).

Basically three years ago the computer died. I was not confident enough back then to fix it so I bought a new one. This year I decided to play around with it to see if I can get more use out of it as a home entertainment system for the TV. So I pulled it apart, removed all the dust, cleaned the heatsink, took apart the video card and did the same. Applied new thermal paste and the computer now started running like brand new. However before I fixed it the fans both the CPU and system fan were running at full pelt. After I fixed it this stopped. However I encountered a problem. As I copied data from the hard drive to a new computer by removing it the hard drive had errors and I could not operate normally so needed to do a full reset. That was all well and good.

Then after I fix it and the reset is done the operating system and computer work flawlessly. However there is one problem. The fans are now running at full pelt again. I have accessed the bios and it appears I cannot adjust the fan speed there.

Does anyone more experienced than me know how I can achieve this, thanks.

AMD usually has something like Cool n Quiet, which is a mode you can engage. Not so sure on a OEM board though. Lots of people seem to report this problem with the motherboard. It should automatically control fan speed.

If you aren't on the latest BIOS revision give that a go.

Or replace the CPU cooler with something larger and quieter, if possible.

Thanks for that, I have a feeling you are right. The bios appears to be the latest version but then again if no updates are available perhaps it is no longer supported by HP given it is a 2013 model. It works, its just the fans are loud.

Also please take into account that the fans themselves can be the reason of the problem. Newer fans are better. Replacing the fans can make a change. Even after finding the right application, you may need to replace the fans.

Back then, MSI had Control Center, a software program downloaded from the MSI website. That'll give rudimentary fan curves, only 2 points, but you can set the slider as you wish. The other option is SpeedFan, which works like a champ, has multiple ways to setup fans, speeds, temps etc BUT is a serious pita to get setup in the first place. Easier to learn Microsoft Office products.

In uefi bios, there is the option to control fan speeds, but it's an all or nothing option, you set the range of operation and min/max duty cycle, and hidden fan curves do the rest, no changes possible.
