![]() ![]() Postage), with cost rapidly falling depending on how many you build. It was quick and simple to build on stripboard/Veroboard and works perfectly, taking less than an hour to build and total cost less than £3 (most being This is a logic level MOSFET, other alternatives areĪvailable (like NTE2985, IRLz24 and FQP30N06L mentioned). Having plenty of 10k resistors and 5.1V Zener diodes, I decided to order some IRL530N N-channel MOSFETs. Note fan wire colours are a guide only and may not match My addition to it is a couple of easy board layouts you can consider, and a confirmation that it works This isn't my own design, it's lifted straight fromĪ TechPowerUp forum post and a similar version is onĪ post on Electrical Engineering Stack Exchange. System fan reduce to a nice quiet speed is welcome, but it has the ability to pick up speed when you stress the CPU or other hardware causing the internal ![]() Only premium or more recent motherboards have the ability to speed control 3 pin fans, and it's a nice ability because when the PC is mostly idle, having the I have a couple of old Intel H61 based (released 2012) Mini ITX systems where the motherboard has 4 pin system fan header, but the case contains only 3 pinįans, and thin varieties that are hard to get in a 4 pin version.Ĭonnecting the 3 pin fan to the 4 pin fan header makes it run full speed, all the time. The quick and simple PWM to standard 3 pin fan controller ![]()
