I recently built a pc using a z420 motherboard and an e5 2670. Everything boots just fine, using ecc memory with an 24 pin to 18 pin adapter. However, every time i boot the pc, the cpu runs at .24 ghz then shuts down due to thermal issues. I am using the EKWB EK Fluid Gaming A240 cooling kit that was given to me by a friend. The kit worked just fine on my old i5 3470 but that was when i used real coolant. This time, i am using plain tap water for a little while. Any help would be much appreciated.
