Had to install this as my refurb H100 started to leak!
with the hydro 100 , fans set to high on the pump I was idling at around 30 degrees, after installing the h70 I am idling at 40-50!
4770K at 4.6GHZ
Part of the problem is I have is I am not able to get all fans running at full speed using the motherboard headers. Currently using the performance Corsair SP120s on the rad, using the H70 pump to control the speed is useless so I have connected them to the m/b headers and the pump to CPU_Opt, using as gigabyte x87x-ud5h. Using gigabyte smart fan tool works on extreme, but the minute you exit they default back to stock. Tried using the BIOS to set them but nothing changes. Hopefully will only be using this setup for a couple of weeks until my h100 comes back from Corsair
Any suggestions please?
