Now am sure many people have tried this but i thought id try be helpful (Perhaps)

Instead of buying these premium led lighting i went for a simpler approach which allows more flexibility in the sense i can add as many as i wish not be restricted by cable lengths etc.

What you will need
  • Soldering Iron
  • Solder
  • Fireproof surface
  • 4 Pin molex (With only red and black wires 12v) OR 3 pin fan connector with red and black wires (12v)
  • 30cm LED SMD Strip 3528 (You can get these for a pound in any colour you wish on that bidding place)
  • Insulation Tape

Tutorial is simple as this..

Take either your 3 pin fan connector or your 4 pin molex and cut the wires and strip the end insulation, Do the same with the wires on the SMD LED Strip.

Take the exposed cores of the wires and twist them together from plug > Strip. So black to black and red to red.

Apply solder to exposed cores to secure them together well and wrap in insulation tape (Wrap individually don't let the red and black touch at all else it will short out)

Test and apply lighting to were you want it :) This is my results on a 12LED SMD Strip in Ice white

I aint sure if a tutorial exists like this but i was just doing mine properly today and thought id make one and share.

Added benfits of using a 3 pin fan plug like i did. My controller can adjust the brightness and turn them on/off too as LED's are dimmable on these strips :)

Total cost for me was about 1.50 :) Simples!

Yep :) if you look around you will find some and in the description they state they have 3M Sticky backing on which seems to work just fine. If they fall off you can try numberplate tape :D

Got my obsidian 350d windowed coming on friday, so will defo do this now....
Have a load of old fans in the office, will cut the 3 pins end off to save me some money...

Thanks again for this thread

Edit: do these need to be plugged into a fan controller?
