Step aside outdated "Speedfan" app, here is your successor.
If you want full control of all your fans (Including GPU fans) then this app is King and it's free. When I say, "Full control", I don't mean that you can just control all your fans, I mean fully control all your fans simply and creatively. The app is call "Fan Control". JayzTwoCents has a great get started video:

Here is how I have mine setup: https://imgur.com/nzEz9z4
Here are a few things you can do with "Fan Control" (Look at the picture in the link above to get an understanding):
-
Create as many fan curves that you want or need
-
Each fan curve can be assigned to a thermal sensor (CPU, GPU, or whatever sensors the motherboard is reporting).
-
You can combine individual fan curves into a Mix group
-
You can assign a fan curve to fan that is connected to a fan header, or you can assign it to a "Mix group". Any fan or set of fans that is assigned to a Mix group will automatically be assigned to the fan curve that has the highest temperature sensor (it will switch back and forth between the hottest sensor that a Mix group is assigned too). Remember each created fan curve is assigned to a sensor (CPU, GPU, or whatever sensors the motherboard is reporting).
-
You can do the same thing with GPU fans and anything connected to fan headers that some GPU cards have.
-
There is a lot more features
-
The Fan Control project is quite active with timely updates which can add new features.\
For those resisting by saying that FanSpeed is good enough or FanSpeed is simple and easy to use also need to know that the last day FanSpeed was updated was 21st of February 2015. That is over 7 years now, and it wasn't even built for Windows 10 or Windows 11.
Please NOTE: The app doesn't install on your computer; it runs with the unzipped folder. This allows you to move the folder to wherever you want (Even on a flash drive).
FYI - For Mac users running Windows: Most of you probably have a MacBook/Pro which is a laptop. It will not work as the developer states that laptops are not supported.
I got a similar issue.. My laptop fans started to operate constantly even though it's in idle. I checked my task manager.. It appeared that my CPU was in 100% usage and the process that took the most of my CPU resource is Microsoft Windows Search Indexer & Microsoft Windows Search Protocol... When I stopped those processes, my laptop fans started to slow down...
Windows updates these days may update your BIOS and that is the most likely cause of the problem, since there is no setting in Windows to affect the fans, the setting is therefore in BIOS
