The stock fan that came with the cooler always stops spinning, randomly.

Strangely, it "tries" to spin, but then stops for a few seconds, and repeats, as if it is struggling to rotate.
I would have to give it a spin boost with my finger to get it going.

Sometimes it just works as it should.
It is plugged into the motherboard (CPU Fan 4-pin).

Can anybody give me some insight as to how to fix this, without having to connect directly to the PSU?
Could this be a MOBO or BIOS issue?

Basically, the fan is running in PWM mode. When your CPU gets hotter, it will spin up accordingly, and when the CPU is colder, it will spin slower, down to nothing.
Had the same "problem" with a Scythe Shuriken before.

This is the issue, if your bios has temperature control, lower the temperature at which the fan "bottoms out".

but even if my cpu is under load, it won't spin.

honestly, the only possible way it will spin, is if I give it a boost.

Just now, as I turned my computer on just a few mins ago, my fan wasn't even spinning.

I had to open my case and give it a boost.

Plug the fan into a different header. You can also try using a molex adapter and use a 4 pin. If neither of those things remedy the situation, the fan is junk.

I've plugged it into the other only 4-pin on my mobo (system fan 2), and it runs at all times, but only at 400rpm or less.

Wouldn't it only run at 400rpm as well, if plugged directly into the PSU?

Seems to work best under CPU Smart fan control when plugged into the CPU Fan 4-pin. It gives me 1200 or more rpm.

+1, try a different power connection.

If it fails to spin with a MOLEX connection or separate power connection then it may be trashed.

You could try spraying the inside with some WD-40 or lubricant of sorts and just give it a good spin in each direction to grease the gears abit.

Have you tried connecting it to a 3 pin header on your motherboard? That should get it to spin at it's highest rated speed, 2000rpm's I believe.

how are you measuring the rpm? - you do know the bios and monitoring programs don't always get it right

I can still connect to a 3-pin header, even if it's 4-pin? okay ill give it a try.

Yes, the fan will run at the voltage from the header(12V).

The fourth pin is for PWM support which regulates the voltage to the fan and thus automatically controls the rpm of the fan.

im using speed fan or bios.

Edit, what temps are you getting?

what temps are you getting?

on idle, i get 41/38, according to RealTemp.

if I run prime95, i get 50 on load, and 60 on load from IBT.

I just connected the fan to the 3 pin header. still not spinning on its own.


EDIT: just gave it a boost with my finger... now it works :confused:

If you have a fan of the right size, ad it as replacement, else it is time to use the warranty.

If you just purchased the cooler, get an exchange. Otherwise, MC sells the exact fan for $11.99 (CM BladeMaster 120mm PWM). I am surprised to hear that you are having problems with it, as I own three of these that perform quite nicely. I suppose there will always be defective units.

Problem has been solved.

Plugged it into a 3-pin header, the one beside the CPU Fan 4-pin header.

Works perfectly now, with 1200rpm or higher at all times.

Thanks a lot for all the help people! :)
