There are loads of youtube videos that will help you with this so i'm not going to go into any more detail than that.A fan controller is probably the last thing that comes to your mind when talking about PC accessories. Unplug the leads into your motherboard and drives, un screw the PSU and it should lift out of the case. If you don't have an old/separate PSU I reccommend removing your PSU from your PC to test this. If you have an old PSU, use that! Once again it's not my fault if you break something (Including yourself) during this stage or any other. I don't reccommend LED fans, mine were LED and the change in voltage from changing the speed makes them go dim, not a massive issue but you might not want thatĪ computer or computer powersupply to give the fans power The 3 speeds will be off, half speed and full speedīeing able to turn case fans off helps you keep your computer quiet when you don't require the extra cooling, the two fan speeds allow you to turn the fans up when necessary and dow to keep the system quiet while still coolingĭC fans - I used 2 i bought on Ebay for about £1.50 each from China, they came with 2 wires for power(+/-) Not PWM 3 pin/wire type and a molex plug so they would run at 12v constantly (Loud) Please comment I can't be held responsible if you break stuff, i have tried to describe things as thouroghly as possible but if stuff breaks it's your fault not mine. This is my first Instructable so I hope it's alright :) I couldn't find a decent tutorial on fan controllers so i've made this simple one. This instructable should help you build a simple 3 speed fan controller for any 12v dc computer fan.
