Hi,
2 weeks after I removed the 120mm blowing on my NF7-s mosfets, one got to hot and unsoldered itself, I was only running 1.95v @ 2.8GHz..
The mosfets were sinked, and normally they don't ran so hot, but I was running distributed.net for 2 weeks and, yeah, the mosfet with the smallest heatsink unsoldered itself resulting in a 12v rail shortcut on the mainboard. I removed the mainboard from the case, unsoldered the 2 pins with were still connected to the board, then the shortcut in the board was gone..
Now I have a board with only 5 mosfets anymore :/
As I used a little to much AS adhesive and a little to less AS3 I think it will not be possible to remove the heatsinks from the mosfets..
Now I want to solder the one that had fallen of back on .. But how you get the board and the mosfets hot enough so the solder will aplly to both sides?
Some pics..
