Semi passive cpu fan

Hello,

I am planning to buy this motherboard: K8NF4G-SATA2.
I will undervolt and underclock the cpu.

I would like to have cpu fan always off until cpu reaches very high temperatures.

Is it possible? Does this motherboard supports pwm fan control? Or I need to buy another one?

Thanks in advance for any reply!

Alternative motherboards

In alternative, can you say me if you have obtained some good results with motherboards on this list?

K8NF4G-SATA2 does not support PWM fan control. Biostar Tforce 6100 has Smart Fan Control and allows underclocking/volting.

Do I need a special fan?

Ok thanks, I will search a tforce 6100. A little question, do I need a special pwm fan or a normal cpu fan can be controlled too?

Normal (3-pin) CPU fan can be controlled.

recently i tried a revoltec fan controller - it made all of my fans (but one) whine and make loud, irritating noise when below full 12v - making it a useless p-o-s, grrr. pwm in itself seems to be fine but you've got to be lucky with your choice of fans as some are just not getting along with pwm. i was unlucky as only one fan in my collection (and i tried few brands and sizes and makes) was ok with pwm. i'm not sure tho if pwm though mobo works the same as pwm through a rheobus. anyway, what i'm saying is stay away from 3,5 revoltec pwn controllers - i talked to some people who had these and most of them experienced this kind of problem.

also, i guess there are special 4pin fans to work with pwm but they are v difficult to get as only one company makes them - it's been discussed somewhere here

hope my blabbing helps tho it's bit off-topic
