    LED Head
  1. This cooler is a great performer, and I have put some nice fans that have a lot of static pressure to get some good performance. I wanted this cooler as soon as I read about it, and even had to buy a replacement motherboard just to fit this beast. I even tried replacing this with a 360mm aio cooler, but went back to this since it rocks so much. I'm a proud owner. I have had this cooler for about a year on a computer that is on 24/7 and have run into a problem. The Cooler Master logo started to get dimmer and dimmer and dimmer. Being one who likes to tinker with things, I took it apart. I found the LED's being connected to 12V and found three 5mm LED's in series with no current limiting resistors. A very bad design indeed. The LED's are probably being over-driven for the sake of brightness. I figure it's not a question of if the LED's will fail, but a matter of when. After doing some testing, the white LED finally failed and all 3 LED's went dark. I've since replaced them with some pretty cheap LED's that have resistors for 12V operation. It's all I had on hand, and these aren't ideal but I'll get better ones later on. Considering the price of this cooler I'm disappointed this was done so cheaply. Hopefully Cooler Master will take this feedback and design LED's to last in future products.
