Can't monitoring fan speed

[nicolafrosi]

I have a Samsung NP350Ev4 - S05IT. I tried to monitoring fan speed but without success. The BIOS is an American Megatrends P08ABE and it doesn't read nothing about fans. I tried also with fanspeed and other software with the same results. What can i DO?
thanks

Check if you CPU cooler fan has a 3-pin or 4-pin cable connecting to the CPU fan header on motherboard. AFAIK (and I might be wrong) is that you can do RPM control of the CPU cooler fan if it has a 4-pin cable, connecting to a 4-pin header on the motherboard, via PWM. Bios is support to report that RPM. The RPM is set by Bios based on the temperature sensor reading. The fan RPM is a result of temperature.

You may have to look at your motherboard's documentation and see the type of cabling your CPU fan has to the motherboard.
