Case fan installed correctley?

post #1 of 11
Thread Starter 
I installed the Arctic Cooling 92mm F9 PWM fan & its super quiet spinning very slow, just enough to feel a small breeze from behind. Im just curious if ive installed it right? I just pluged the power connection into the motherboard on a vacant 4 pin type connection. And some small 3pin connection which details teh fan rpm speed.

The instructions say I can change the speed in the bios. But not sure exactly how to do this?
In the bios, under PC health status. It has 2 options.

CPU smart FAN control [enabled] - not fixed speed, but varies accrording to cpu temp. (is this my new case fan or just the cpu fan itself?)

CPU smart FAN mode [auto]

thanks.

disable smart fan for max speed. your sig doesn't say what mobo you have so its hard to find out.

it depends where you plugged it, if you plugged it into the CPU fan spot then yes, if its just some random spot then no thats not it, but you can set smartfan mode for the fans if you want to, but i would set it to voltage instead of rpm. or just turn smartfan off and have your fans at full blast

No sure what your motherboard is but with mine I can control all of fans through a software that ASUS has. Try to find software for our motherboard.

It just spins at 900rpm all the time at all cpu temps, so ill disable that smart fan. My mobo is a gigabyte p-55 type, (forget the rest of the number)

So you know, there are two main types of fan headers on boards now days.
CPU_Fan and SYS\\CASE_FAN.
CPU fan can is variable with respect to CPU temp under bios, if you would like.
SYS\\CASE fan is typically 100%, and not in respect to CPU temp. (I think).

Either way, on the SYS_FAN2 i believe on Gigabyte motherboards, it wasn't pushing out 12v... something like 7v instead! I don't know if it's in the p55 revisions, but I think it is.
It'll say which header it is, printed on the motherboard. Check if it's SYS_FAN2 \\ 3 or similar

The 2 only options in my bios are CPU smart FAN control & CPU smart FAN mode. Both dont make a difference. Still cant get the fan to always spin at its max which is 1800rpm irrc.

I'm sorry if this sounds obvious, but did you follow the installation guide provided by AC (assuming your fan is of the PST variety)? I remember having a similar fan of the 120mm variety and I was slightly confused at first. If the RPM-sensing wire is not connected to the vacant plug in the fan, the RPM values will not be displayed correctly.

As far as I can tell, plugging the fan into the 4-pin CPU header and setting the Smart Fan Control to disabled should allow the fan to spin at full tilt.

Its plugged into the separate sys_fan2 with the 4 pins. I dont get why it shouldn't just go at the full 1800rpm speed? And I cant find anything in the bios that allows to set it at full. The voltage must be limited, but im lost. Ill might try the cpu header now.

My old Gigabyte board had a separate Smart Fan control in the BIOS for the system fans, but it really seems yours doesn't

I assume you have your CPU cooler plugged into the CPU header so even if that would work for your case fan it will be no good for you since you still need your CPU cooler connected somewhere and the CPU header is the preferred spot.

If you find out the specific model for your motherboard can you post it here? There may be others here who own the same board and can give better guidance.

The control utility for Gigabyte boards is EasyTune, I think. As a last resort, if you happen to have it installed, you can check if you gain any control over the fan operation from there but if you can't control it from BIOS, there's a chance that the software won't help you either.

I apologize I couldn't be of any real help here

I have the GA-P55A-UD3 (rev. 2.0)

Could I get an adapter that allows me to just plug the fan into a direct feed off the power? So it should be full 12v?
