Had a Nepton 120XL for about 11 months and then the pump stopped working. Got a new one from the warranty but when i install it the pc keep restarting every 3-5 second. When i remove it i can see it has contact to the cpu but maybe not fully contact or hard enough. When i apply the stock cooler it works like normal. I have tried different pin connectors for the pump. The fan works as i can see it spin. Is there a sensor on the cpu(Intel 4770) maybe that keeps making it to restart?
