If your fans are not running well in your system, it could be that your PC is running at too hot, leading to slow and reliable systems, often with occasional crashing.
I use Speedfan to test the temperatures in my system and this can be downloaded freely from…
Click on the link above to download Speedfan and then select Run
Accept the license terms by clicking I agree
Select the shortcuts you want to install
Select the installation location (if unsure leave as default)
Speedfan will now install and you will see a screen similar to this…
Once install has finished you should see this icon on your desktop…
Double click on the icon to open Speedfan.
On opening Speedfan will scan your system to monitor fans, voltages and temperatures.
To find out what temperature your processor should be running at you should refer to the manufacturer’s information for your motherboard, however when the system is in ‘normal’ use, a rough guideline for the processor is that it should not exceed 60 degrees C – that’s the Core temperatures in the table.
The item marked GPU is the temperature of the graphics processor. Again you should refer to the manufacturer’s information for operating temperatures. If you run 3D gaming cards this is an important factor to check as the 3D cards can run very hot when processing graphic ‘heavy’ games and you may need to improve your cooling by adding more fans or changing to more efficient units.
On the left you will see the fan speed. Don’t worry if some of these show as 0 rpm as the fan may not be monitored by your motherboard. There is a fan on the processor, usually a fan on the graphic processor (GPU), a main system fan and usually a fan inside the power supply unit.. If you see zero values on the table in Speedfan then visually check that all the fans are working. Generally you only need to worry if your system is running too hot though.
