How To Setup & Use SpeedFan?
If you know how to set up automatic fan speed then you should use custom fan curves and set up a fan speed that will increase in proportion to CPU temperature.
However, if you are a newbie and for the first time you are using this CPU fan control utility, then you may damage your computer with a utility like SpeedFan.
First you should learn the tutorial and instructions so that you can safely configure fan settings. You can also read a quick guide on how to set up SpeedFan to test fan speed.
How Read SpeedFan Temp 1, 2, 3?
Many users still ask on forums what Temp 2 on SpeedFan is or which temp is accurate CPU. First, understand that SpeedFan is a flexible temperature monitoring utility.
It detects and labels thermal sensors according to the various motherboard, chipset, and super I/O chip configurations. That’s why you will see the Tcase label as the CPU core, Temp 1, Temp 2, or Temp 3.
However, if you have installed an aftermarket graphics card then you can also see GPU fan and GPU temp readings. Unlike temp 1, temp 2, and temp 3, the GPU-related readings are easy to understand.
You can also run prime95 and while stressing the CPU, take note of readings that quickly increase, it should be your CPU core temp. This utility usually shows it as Temp 2 or Temp 1 but it’s still uncertain
Where does Speedfan get the information it uses to monitor the computer? This software utilizes S.M.A.R.T and DTS sensors placed on motherboards and gathers data. Then it shows you the information in a simple way.
How To Control Fans Speed?
This fan temp monitoring utility can easily let you change the CPU fan speed. If you are certain that your CPU fans are not running at their ideal RPM speed then you should take control and adjust the fan speed manually.
How to Make Speedfan Start with Windows 10
Use Windows Task Scheduler “taskschd.msc” to enable automatic startup. Here’s how:
- Go to start, type Run, alternatively press Windows+R
- Type shell:startup and press Enter
- Copy and then paste the shortcut of Speedfan into that folder
- Restart your PC, it should start once you’re in.
- To remove it from running at startup, delete the shortcut.
Fix SpeedFan Not Working or Detecting Fans
Recently due to the release of modern CPUs and motherboards, SpeedFan reads CPU temp wrong or it simply won’t detect/show fans. To fix this problem you have to configure its settings a little or make sure that the motherboard is compatible.
Here is a complete guide if it’s not showing fans. The same driver not installed problem also occurs in Windows 10.
Is it Possible to Damage a Computer With a Utility Like SpeedFan?
Yes and No…!
Yes because if you don’t know what you are doing you may end up causing CPU fan error problems.
No, because if you simply saw some tutorial to use this utility then you won’t need to worry about any errors.
CPU Fan Speed Software Alternatives
If you are looking for programs like SpeedFan then you should try Argus monitor and MSI Afterburner. These are the best alternatives to control fan speed.
Rainmeter is another PC customization utility you can use to install SpeedFan skin and it will perform the same functions.
We conclude the SpeedFan review on a line that if you want to control the CPU fan speed then give a try to this tool.
