The installation process is easy with a typical install time of under 10 minutes and it does not require the use of any other tools other than a scredriver to remove and/or secure the motherboard. An included fan speed controller allows you to quiet down the fan to just the right balance of noise and performance for the most discerning user.Ĭomes with a 120mm fan with fluid dynamic bearings for years of reliable performance and no need to purchase a fan, though you have the option of adding a second fan for more performance, hardware for second fan installation is included. A universal mounting bracket supports the widest range of current AMD and Intel sockets, including the latest multicore Phenom and i3/i5/i7 processors. A combination of high performance and low noise in a package designed for use with 120mm fans, no need to push the limitations of your case space with a 140mm fan based heatsink! The EFZ-120HA4 utilizes five 8mm heatpipes that directly contact the CPU and are intertwined to provide ten effective heatpipes worth of thermal dissipation. It provides among the best thermal performance in the industry at the lowest noise levels possible. An extreme performance heatsink designed for the most demanding gamers and overclockers, it'll satisfy any user in any application. 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.We had to build a successor to top our new heatsink line and the EFZ-120HA4 was designed just for that role. 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 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. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. 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. 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. The size of fan you need will generally be determined by the size of the fan fitting position in your PC case.
