My fan is not working as intended, is it faulty?

My fan doesn’t spin when I start up the PC, is it faulty?

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your motherboard, it's possible that the motherboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors or deactivate your motherboard's automatic fan controller in the BIOS.

I get a CPU fan error although the fan is running, is it faulty?

Some motherboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.

Can I power fans via a wall socket?

We don't recommend running a 12 Volt or 24 Volt fan via your power outlet. One of the main reasons for that is the lack of a universal standard for 12V and 24V power supplies, whereas there is a USB standard. This means that you potentially need several adaptors to be able to connect fans properly to the power supply. Therefore, we would recommend using a 5V fan instead of a 12V or 24V fan.

Can I connect multiple fans to one fan header?

Yes, with certain things in mind, it is possible to connect several fans to one fan header. 
The most important point to consider is the collective current draw of the fans used.
The maximum input current for a specific fan can be found on the product page on our website in the "Specification" section.

The fan clips are almost touching my graphics card, what should I do?

On some motherboards, the fan clips may be very close to the rear side of VGA cards installed in the first PCIe slot. In this case, please insulate the fan clips using duct tape or shrink-on tubes where they come close to the VGA card. Alternatively, you can also avoid this issue by installing the cooler turned by 90°.
