since u have no knowledge on how to do it....i suggest starting with something alot simpler.... a simple high-off-low switch.

what this basically does is switch the voltage going to the fan..so if u put it to 12v..itll get full speed and if at 5/7v ull get the low speed... the lower the volts, the slower the fan.

12v/7v switch

12v/5v switch

wat u need is an on/off/on switch. wires and all necessary connectors to connect it to ur PSU and fan. heatshrink/electrical tape bla bla bla...(All this u can get in Jalan Pasar)

this is VERY easy to do..and i successfully did a few when i had ZERO soldering knowledge. its just a matter of following the very simple diagrams in the link and u have urself a fan controller.

FYI, i made this to control my 1x12cm and 1x8cm Delta FFBs and alot of other noisy fans i used to have in my case.
EDIT: i had 1 switch controlling the 2 FFBs and 1 more switch controlling around 4 fans.

point to note: whatever fan ur trying to control, ensure that they are able to run at 7v or 5v (whichever one ur planning to do). reason i state this is because in the case of my 4x 12cm Delta FFBs, only ONE of them can work at 5v. the other 3 wont, even if i give it a 'kick start'. but ALL of them can work at 7v.
