I have a Corsair H100 with 4 AP15s cooling my 2600k at the moment. It works pretty well to be honest, and I have been pretty happy with it. The only problem was that I had to mount it in the bottom radiator bay of my CM690-II case as there wasn't enough clearance on the motherboard heatsinks in the top bay - even with two of the fans mounted in the roof section. Everything is fine while the system is running, and the pump can circulate the water well. The problem occurs when the system has been switched off for a period of time. An air pocket seems to form in the pump and therefore no water is circulated! I have to move the case around to get the water to get into the pump before it starts to cool the system - I am guessing this is because the radiator is designed to be fitted above the pump. Looks like I will be sending it back and getting a proper loop after all, unless someone can come up with another suggestion?
Totally agreed. I had my H50 mounted upside down flat in the roof and normal and never had any probs with it.
my h80's radiator goes glug glug glug when i fiddle within my pc no difference in temperature or performance though whetever the position i have on it.
It will be the second time I RMA one - the first had the fan controller pack up shortly after installing! Will contact supplier on Monday for an advanced replacement...
hmm, never liked the closed loop setups. I'd deffo RMA it, and i'd think about investing a little bit more moneys and getting a nice loop. with a custom loop you can always mod, add to it and transfer to new build! I've got the same case as you with 2 240 rads.
I used to run a loop in the same case with an XSPC RS240 and an RX240 but gave up and went back to air with the same results - my aim then was to cool a 1090T in the most silent way possible. The H100 performs very well, its just the air issue - I will give it one more chance with an RMA and if not will ask for a refund and will build a loop again.
All closed loop cooling solutions will have a small amount of air in them to allow for the water to heat up and expand. I've had both the H50 and H70 and both had air in them. I would be surprised if the retailer took it back as an RMA for that reason, I think you may be better off repositioning the rad above the pump.
