Best CPU fan control software?

wrong!!

Speedfan can alter any voltage or PWM of a fan -- IF the sensor chip supports it!!!!!!!

The big problem nowadays is so many mobo mfgrs are skimping on what used to be a very common feature -- allowing software to modify the voltage of a 3-pin header. If you get a good board that can do this, it means that you can software control fans by directly changing their voltage, without the 4-pin pwm. I have had systems before with 3-4 fans, 3-pin, entirely controlled by software cooling.

I found that the boards that came with a vendor supplied/advertised 'cooling software', such as ASUS generally had awesome support for changing 3-pin voltages via software. A board that isn't advertising software cooling might not have this feature and you are going to have to adjust the fans with a 'fanmate' resistor + dial device.

I have a Tyan S5211GNR socket 775 server motherboard with six fan headers, including the CPU. According to the Tyan manual:

System Management
- SMSC SCH5027 and EMC6D103 with hardware monitoring
- One (1) 3+1-pin CPU fan header with smart FAN control (by SCH5027)
- Five (5) 3+1-pin system fan headers with tachometer monitoring, three (3) of them support smart FAN control

I see the EMC6d103 chip in the Advanced configuration, but PWM 1 to 3 do not give me the option 'Software Control'. I see only:

On zone 1 auto
On zone 2 auto
On zone 3 auto
Always on full (this was set for all three)
Disabled
Controlled by hottest of zone 2,3
Controlled by hottest of zone 1,2,3
Manually controlled

Try manually controlled. Every i/o chip has it's own terminology. MrK6 has a Gigabyte board and has to choose 'software controlled', I have an Asus board and have to choose 'manual'.
