I recently purchased an H150i Pro, Installed it on a 5930K Stock CPU
Temps were much higher then my 4+ year old H110.
Both coolers were mounted on the top of a 760T as Push/Exhaust.
H150i | Idle-33°c | Max-51°c | Ambient-71°F
H110 | Idle-28°c | Max-38°c | Ambient-71°F
I tried mounting the H150i twice.
Tried first without iCUE software
Second remount with iCUE software 100% fan.
Second time with the same TIM I always use.
However I could not find any pump RPM setting it was always grayed out.
I know these temps are not terrible but, the performance gap is huge IMO.
However my entire system was warmer, Ram, VRM, even the plastic RGB Corsair logo was very warm to the touch 89°-90°F measured with a laser thermometer. 82°F with the H110 installed.
I ended up returning the 150i, Corsair's excellent RMA service replaced my failing fans on the H110 so I have it back in the system working perfectly.
Some people seem to think this was a faulty pump or something.
I've remounted the H110 probably 6 times in total on this PC for cleaning over the past 4+ years. twice in past couple weeks, and the temps are always the same.
Is the 280MM radiator supposed to perform that much better?
Possibly larger copper block?
I will keep this H110 forever.
