Hope it helps!

Bytheway, The fan comes with an adapter with 2 wires red and black just like the one in the picture, Does it work?

That adapter is for connecting the fan directly to the power supply using a spare molex connector instead of connecting it directly to the motherboard.

A fan controller like Shootist linked to will work. Another option would be to return the fan you bought for one that is PWM capable; uses a 4 pin connector on the motherboard instead of a 3 pin like the one you have, and can be controller by the bios (yes I checked your motherboard manual and there is one 4 pin/PWM connector in addition to the one for the CPU fan; as well 2 3 pin headers, one of which you are using with the new fan).

Sry I'm afraid i need more explanation, May you tell me if i get that "3 to 4 pin adapter" and mount it to the 4 pin place in my motherboard will let me control the fan speed? it would be great if you send me a picture for it, If not possible to control my FAN by using that adapter, I can buy another PWM FAN with 4 pin wire like you suggested. Hope u understand my bad English.(would be good if you use simple words to let me understand ur meaning).
Thank you

It seems your motherboard only has some rudimentary fan controls in the BIOS. But you do have 2 4 pin fan connectors. one 4 pin for the CPU fan and the other 4 pin can also be used for a second CPU fan, a push pull arrangement on certain types of heatsinks.

But you can still connect a 3 pin fan to that 4 pin connector.

The adapter shown in the other post allows you to connect a fan that would normally connect to one of the motherboards fan connector, 3 or 4 pin, to a standard power supply 4 pin molex connector.
No it does not give you speed control without using a separate speed controller like I linked to in my other post.

A 3 pin to 4 pin adapter won't allow for fan speed control for one very simple reason, there is no 4th wire from the fan itself which is what is needed for that to happen.

I understand, I have CM Hyper 212 plus HS and i use only 1 push FAN and only 1 4 pin connector and the other 4 pic connector is not used.
I'll buy a separate speed controller like u linked before or i think it will be more better to buy PWM fan and throw this CM Blue LED noisy fan in trash, I think PWM is close price to separate fan controller.
Thank you.

Ohh, u mean the fan itself has only 3 wires and there's no 4th wire that is responsible for fan speed control so whatever adapter i use will not work.

Thank you for your explanation.

Not really. I have 3 120mm 3 pin case fan and 1 120mm CPU fan in my system. 2 of them connect to 3 pin headers. The other one connects to the secondary 4 pin header, CPU fan to the CPU header. All of them, including the CPU fan which is 4 pin, are controlled by the BIOS settings and set to Silent which makes them run at around 800RPM, including the CPU fan. If the system starts to get hot the BIOS raises there speed accordingly. CPU first as that is what gets the hottest.

The BIOS lowers or raises the voltage supplied to the fans to increase or decrease there speed.

Hi Un4GiVeN78

To make Speedfan work you need to put a tick in Automatic Fan Speed honey
