Hi there,
I installed my Noctua NH-D14 according to the manual, and I used the SecuFirm2 Mounting system. However, while the heatpipes to transfer heat out, and the fan is working quite well, I am concerned if I overclock a bit and give it 100% load, it may overheat. Because my motherboard is a GIGABYTE one, I do know that I may have to give it more voltage or something. However, when I go into my BIOS, it only lets me raise the fan speed, and does not allow for extra voltage.

How do I make the fan fins move? Thanks!

My Specs:
Gigabyte FM2-A55M-DS2
AMD A8-6600K
Memory is low profile, it is compatible with Noctua Fan

If the fans don't both work when connected to the Y-adapter, you should try connecting them separately, but a fan controller is not your only option - I looked up your motherboard, and there are two fan headers, one labeled "CPU_FAN", and one labeled "SYS_FAN", though the second might be too far for the fan cables to reach. If it's too far or you have some other fan connected to the second one already, there are fan adapters that allow connecting the fans to molex connectors from the psu, and they tend to be less expensive than fan controllers.

Your message is confusing. If the fan fins aren't moving, that means the fan isn't blowing - Noctua fans aren't like Delta fans that have some fins that move and some that don't - so how can you say it's working quite well? Also, are you trying to increase the voltage to the fan or to the apu?

Sorry for making it not clear.
The BIOS reports the fans with 0RPM, and from what I saw online it said to increase voltage to the fan and that may move the fan. However, I cannot find the fan voltage increase thing. I checked the fan fins and they aren't blowing, but cold air is coming out of it for some reason.

If the center fan is blowing but not the front fan of the nh-d14, that would cause some airflow. If neither fan is running, I don't know how to explain air coming out from it.

As far as increasing the fan voltage, that might only happen indirectly by increasing the target fan speed - see the 4th reply (currently listed as being by "Anonymous") in this thread: http://www.tomshardware.com/forum/266476-29-difference-3pin-4pin-connectors

Okay, it seems that the 140mm fan is moving but the 120mm is not. However what can I make so the 120mm fan moves? I just want to have adequate cooling in case something happens

I haven't actually used the nh-d14 myself, but I looked up the online manual, and there are different options for how to connect the fans. Could you please describe how you connected them? (i.e. did you use the included y-adapter, and did you use either or both of the ultra-low-noise adapters?)

I used the Y Adapter- did not use any of the Ultra Low Noise adapters because my motherboard only has one fan connector hub. Not sure if I would go out and buy a fan controller but if that's my only option then...
