So last night, I finally got enough motivation to figure out how to get my Power LEDs working in all my computer cases. All my computer cases have a 3-pin connector for the Power LED, while all my motherboards have only 2-pins for the power LED. What’s interesting is that there’s really only 2 sockets inside the 3-pin connector that are used? I always thought it was a new convention that new motherboards will be using, but the last 2 motherboards I got (one last summer: ECS P4M800PRO-M, and one just a month or 2 ago: abit IL9 Pro) both have only 2 pins for the Power LED.<\/p>\n

I actually started searching online to see where I can buy a 2-pin to 3-pin converter for the Power LED and found this at Directron: 3-Pin Female to 2-Pin Male Power LED Adapter\/Connector<\/a>:
\n\"2-pin<\/a><\/p>\n

Unfortunately it’s out of stock, but most importantly, it’s not the correct adapter. I have a 3-pin connector and 2-pins poking out on the motherboard. What I need is:
\n\"2-pin<\/a><\/p>\n

The adapter that Directron was selling was converting cases that have only 2 pins for its Power LED connector to have 3 sockets. What is the purpose of the 3rd pin\/socket anyway? A quick search online didn’t result in anything that provided a reasoning. It’s also unclear to me if the 2-pin connector is newer or the 3-pin connector.<\/p>\n

Anyway I ended up on this thread: Case LED power indicator connector 3 pin, mobo 2 pin?<\/a> which redirected me to this page: REWIRING A MOTHERBOARD HEADER CONNECTOR<\/a>.<\/p>\n

Don’t let those pictures intimidate you. It’s in fact quite easy to rewire these connectors. The only tool you need is a very thin and firm tool and a pair of hands. I ended up using a razor blade. Initially I tried it with a small flat head screw driver, but it was still too big. On the connector, there are these little tabs that hold the wires preventing them from sliding out of the connector. Use the razor blade and slightly lift up the tab that is keeping it from sliding out. Do be careful as I didn’t know how flimsy these tabs were and managed to snap one of them.<\/p>\n

Anyway, you should also make sure you know which wire you want to move where. One end of this connector will be sticking out and the reversing the cables is not an option. My first try was a failure which ended up with my Power LED blinking when the system was off and the Power LED completely off when the system was on.<\/p>\n

I hope this helps! Now all 3 of my computer cases have a functional working Power LED. I couldn’t believe the solution was so simple.<\/p>\n

While I was working on one of file server box, I noticed that the 2 hard drives which are currently ghetto-rigged into the system were very hot. I had swapped out some 80mm fans because they were starting to make noise in my main box and thought I’d be able to use one of the less nosier fans with these hard drives. The final result is:<\/p>\n

\"ghetto<\/a><\/p>\n

They were originally stacked one on top of another and I was actually trying to stick pens in between them to allow air flow. But then I got to thinking what if the fan goes out? Would these pen melt? So instead, I have it set up like how my Lian Li case does it where they sit sideways and have the fan blowing at it from the front.<\/p>\n","protected":false},"excerpt":{"rendered":"
