General i7 Fan Question

post #1 of 7
Thread Starter 
I have a Cooler Master 212 and I am using speed fan to control the speeds of the fans on the heatsink. The problem is no matter what speed I set speed fan to the RPM's never go up. They always stay at around 760ish... I made sure I went into config and then fan control...I then made a profile for my cpu fan and set up the speed chart so that it would rev up and slow down depending on the temperatures...

I should also note that the fans are brand new.

Anyone have any suggestions?

Have you checked if your motherboard's set to react with the heat levels on the CPU automatically? Also is the fan set to have 750/800RPM max?

Are these fans 3 pins or 4 pin fans? If not 4 pin then they will just go full speed. Which is weird for 760rpm... although these are the stock fans and all. They aren't very good.

The original fans were replaced. I tried going into the bios to change the speed of the fan but had no luck in doing so. The bios just tells me how fsst the fan is spinning.

The fan is a 3 pin fan connected dirextly to the cpu fan spot.

So you're certain the fan you have is over that RPM; Fans may be limited by the RPM maximum

What fans are they??

212 is shipped in two versions -> one with fan 1600 RPM and another 2000 RPM! Most likely that you replaced original fan with cheap case fan (or two) which are for case but not for CPU -> they are limited to 800 RPM max. I will recommend Cooler Master blade series CM120 2000 RPM if you can't find original.
