Speedfan does not recognise laptop fans
Hi, i have a new Samsung R710 laptop, and have noticed that the case fan only comes on when it is overheating, ie when i am playing a game. I was looking for software to control fan speed, or set the temperature threshold lower. I was advised by samsung to download speedfan, which i did, but it does not recognise any fans. Any suggestions ? thanks

Take a look in Device Manager to see if you have any yellow exclaimation mark items such as "SM Bus Controller". It is an indication your chipset drivers are missing.

No, everything is normal in device manager
I can't see SM bus controller anywhere, but everything is fine otherwise

Contact the author of SpeedFan via email after visiting the website to look for your MB/processor combo. Your processor/MB combination may not be detected. The SpeedFan website should have some information on your combo if it is detected (or not).

Hi SlashRevolver,

Your MB/processor may not support temperature sensors that are recognized by Speedfan despite the fact that your rig apparently has a fan, or it may not have any which, of course, Speedfan would not be able to detect.
