Morning all. I recently purchased an HP Z840 work station 2 socket e5 2620 v3 12 core. 1125 power supply. I want upgrade processors to e5 2680 v4 14 core. that would increase watts from 85 to 120. Can I use the standard coolers and that may increase overall fan and blower speed. or should purchase HP N3R5AA coolers at extra cost. Thanks in advance Bob. Weiterlesen...
