Hi I recently made a custom 1.2 metre cable which I am running to a D5 pump and a fan controller which controls 6 fans. The strange problem I am having though is that I get random hard freezes when gaming or benchmarking. My pc will freeze, the sound will buzz and then the system needs a hard reset before coming back to life. I changed PSU and didnt use the custom molex wire that I had made and the system ran fine. I also used my original PSU and was able to use one of the original molex connectors provided and connected the pump and fan controller. This too worked. The only variable seems to be the custom made cable which I was using. Has anyone else encountered this? The PSU i have is a Corsiar HX750i. Many thanks.
