Kingp0dd Posted April 11, 2016 Share Posted April 11, 2016 (edited) I've had my H100 for 4 years now and had no problems with it. I replaced my thermal paste so I: - cleaned old thermal paste off the H100 backplate using paper towel and 70% alcohol - did the same to processor - put back the H100 - plugged the 3pin fan connector to H100 power slot in the wrong position Reference image of H100 controller, not actual: http://i.imgur.com/mwhKtjL.jpg Correct positioning of 3pin fan connector: o x x x What I did was: x x x o x: used pin o: unused pin I noticed that my temps were higher than before I replaced the thermal paste so I went to check what's wrong. It is only by this time that I noticed the LED lights on the H100 controller are off the fans not working. After that, I tried the following: 1. Correctly replugged the 3pin connectors to the right slots 2. Removed all fans from H100 controller Both attempts didn't make the controller light up again. Do you think that this killed the H100?

Genghis_Tron187 Posted April 11, 2016 Share Posted April 11, 2016 If you accidentally supplied power to the Y connector port on the H100, then it is likely fried. Link to comment Share on other sites More sharing options...
Kingp0dd Posted April 11, 2016 Author Share Posted April 11, 2016 (edited) This is where I plugged the 3pin connector incorrectly: http://i.imgur.com/mwhKtjL.jpg This outputs power, right? Not the other way around? Edited April 11, 2016 by Kingp0dd Link to comment Share on other sites More sharing options...
red-ray Posted April 11, 2016 Share Posted April 11, 2016 All four of those are for fans. There should be a Molex connector that the H100 gets power from. http://www.guru3d.com/miraserver/images/2011/corsair-h100/IMG_5008.jpg Link to comment Share on other sites More sharing options...
Kingp0dd Posted April 11, 2016 Author Share Posted April 11, 2016 (edited) Yes, you're correct. I plugged my 3pin fan connector to the H100 incorrectly. Correct way: o x x x What I did was: x x x o After this the LED lights on the H100 controller which indicates fan speed profile stopped working even after correcting the 3pin position. Very stupid mistake Edited April 11, 2016 by Kingp0dd Link to comment Share on other sites More sharing options...
red-ray Posted April 11, 2016 Share Posted April 11, 2016 So basically you connected the tachometer input to +12. I would half think you might be lucky and not have caused any issue, but maybe not. Link to comment Share on other sites More sharing options...
itto Posted August 28, 2020 Share Posted August 28, 2020 Same mistake here. Took out the fan for a quick cleaning and put it back in the wrong way on first try and the lights are out since It slid into the wrong position easily. Bad design no doubt.
