![]() ![]() When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.Īnother avenue to explore is the possibility of using a bay-mounted fan controller. The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. The P12 is available in black, white, and transparent similarly, the P14 is also. Both prove that you don’t need to spend a lot of money to get quiet, high-performance fans for your rig. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows. Overall, we think that the Arctic P12 and P14 are some of the best PC case fans to come out in recent years. But it lacks a USB Type-C port, which is understandable as the case is very cheap, under 50. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. We certainly recommend the Antec NX800 as the Best Budget PC Case with RGB Fans, considering its admirable traits. Screw hole spacings and fan sizesĮlectrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally. If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. ![]() If you have any questions about which fan you should order, please don’t hesitate to get in touch. All our fans are 25mm thick unless otherwise stated. Alternatively, the NF-F12 is a pressure-optimised fan that excels on heatsinks and radiators and the NF-S12A is an airflow-optimised fan that provides excellent. This isn’t really dictated by customer preference, but more by recent designs of PC cases.Īs for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. And when they have a single fan, it’s usually mounted in the rear exhaust. The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. Rear Fan Only: Some PC cases, especially very cheap ones, come with a single fan. ![]()
