Decided on this AIO after going through various reviews. Installed it into my new build (i5 4690k, in a NZXT H440 case).
Installed in the top , and assembled as per the enclosed instructions (fans at bottom so running in push config), bit of dexterity needed due to the springy tubing, but no great dramas.
No fancy application of the enclosed TIM.
Testing: with the i5 at stock Realbench stress test was run for an hour, using hwinfo to monitor temps and fan speeds.
Highest temp on any core was 62, ambient was 22, after testing temps dropped down to 27. Fans speeds started off at 760rpm and during testing went up to 1000, they were inaudible above the 440 fans, warm air could be felt ejecting out of the top of the case so no apparent problems (as others keep saying about the 440s restricted airflow).
Cooler master support: now while the fans were silent the pump wasn't, there was a ticking noise like a fan catching quite audible, not loud, but invasive. I raised a support ticket this morning on CM fanzone website, then went on to Live Chat, advised to record the noise and upload the file to the support ticket.
Recorded with headset Mic (almost touching the pump) and windows sound recorder, uploaded the file and then back to live chat.
Chat confirmed he pump was faulty and needed replacing.
They also provided the following guidance when installing (not included in installation guide.
'When you have the new Nepton, do not install it, but: connect the pump of the Nepton to your system and hold the pump and radiator in your hand when the power is on.
Then wiggle very gently with the pump and radiator and you should hear a sloshing sound. (sound of moving air bubbles)
When the noise is gone, then the air bubbles are no longer trapped in the pump area and you can install the Nepton to your system.
These steps are to make sure that there are no micro airbubbles trapped in the pump area.'
So all in all a good cheap priced AIO , efficient and quiet, good manufacturer support, just let down a little by their QC dept.
