Recently I’ve been running hashcat for some proof of concept WPA cracking with the below specs:

  • CPU: i7 4790k (mild overclock @ 4.5GHz)
  • GPU: 1 x Powercolor RX580 Red Devil ,1 x NVIDIA GeForce GTX 660
  • Motherboard: MSI Z97-G43
  • Case: Cooler Master 370 Elite
  • Cooling: Air: 1 x 140mm fan intake (front), 1 x 140mm fan intake (side), 1 x 120mm exhaust fan (top rear)

With this set up it would run about 245KH/s but I after some time (minutes to hours) it would hard power off with similar symptoms to a dying or overheating PSU, only I wasn’t convinced. I’ve long fancied upgrading to an all in one CPU liquid cooler but I don’t fancy messing around with a DIY version – I’m sure this gives the optimum cooling result, and a the engineer in me loves to build, fiddle, and optimise things, but I just wanted a drop in solution, so I opted for the Corsair H100i Pro as it was readily available is probably one of the best 240mm coolers (2 x 120mm fans).
