4 out of 5 eggsKind of loud

This review is from: Cooler Master Nepton 280L – All-In-One CPU Liquid Water Cooling System with 280mm Radiator and 2 JetFlo Fans

Pros: Cools very well, cores on my i7-5930K at stock speed stay between 24-28C when not gaming or benchmarking.

Cons: The fans for this are loud, very loud. I intend to swap out the fans for a couple Noctua NF-A14 FLX 140mm fans to see if it improves the noise level and cooling capability. Sometimes it makes some odd noises, and I'm not sure if it's the fans or the pump, guess I'll see soon enough.

Other Thoughts: This is my first liquid cooled cpu.

2 out of 5 eggsYou have Been Warned!!!

This review is from: Cooler Master Nepton 280L – All-In-One CPU Liquid Water Cooling System with 280mm Radiator and 2 JetFlo Fans

Pros: Runs almost silent, currently running an Intel Core i7-5820K @4GHZ and even gaming encoding system stays around 50 C. I really like the water cooling system and I'm letting the MB handle throttling and my bed room doesnt get nearly as warm as my previous system which was Air cooled.

Cons: 1) Stripped the threads out of the casing around the radiator one one bolt hand tightening.... -1 Egg
2) The most important aspect of any cooling system is that it works. This unit will fail to initialize(power) the water pump when power the system on at random times. I've tried every possible way to connect even bypassing and going stright to the PSU same result. Luckily one can hear the pump running if you listen closely and it can be resolved by turn the system off and on again. Sometimes this takes up to 3 tries. This is the one thing about this system that has totally turned me against this product and I would not recommend it to anyone -2 Eggs Due to the fact you could totally burn out a cpu using this product....

Other Thoughts: I will replace this product at some point in the future at the moment I cant afford the cash or time to replace.

4 out of 5 eggsGood AIW cooler

This review is from: Cooler Master Nepton 280L – All-In-One CPU Liquid Water Cooling System with 280mm Radiator and 2 JetFlo Fans

Pros: Easy install, Included fans are great, Keeps CPU nice and cool. So far Reliable

Cons: Radiator screws don't exactly match threads on fan mounting screws. They Strip out easily. Pump does not support PWM or Linear speed control. Works *sometimes* off the motherboard, requires a separate voltage regulator for pump control on Z77 MPower. Makes an occasional "fart" sound when an air bubble passes through the pump.

Other Thoughts: Tech support was great. Answered all my questions. Yes the pump really is supposed to run @ 6000 rpm

This review is from: Cooler Master Nepton 280L – All-In-One CPU Liquid Water Cooling System with 280mm Radiator and 2 JetFlo Fans

Pros: Excellent performance, one of the best closed loop systems, outperforms corsair closed loop systems

Cons: tubing failed, i am a huge coolermaster fan and was disapointed with this. i found it to be shocking.

Other Thoughts: i am not mad at coolermaster, i simply wish to find a resolution to this issue

4 out of 5 eggshappy with my purchase

This review is from: Cooler Master Nepton 280L – All-In-One CPU Liquid Water Cooling System with 280mm Radiator and 2 JetFlo Fans

Pros: overall great product. obviously being a 140mmx2 rad installation can be cumbersome. that should be expected unless you are working in a very large case. for a pre-built kit everything is what i expected. easy-ish to install and simple. average performance if you compare them to custom water kits that are 3x the price.

Cons: i am used to installing custom water cooling solutions and when i was installing the pump/waterblock onto the CPU i actually snapped a screw in half tightening it on (you can really crank down those custom blocks). coolermaster support was great and sent me out a new accessories package to replace the screw. however, i would still have beefed up everything a bit so you can torque down the screws more.

in addition the water block is a bit lackluster (when compared to custom options). it isnt doing the greatest job of transfering heat from the CPU to the internal coolant to circulate up to the rad. overall performance is similar to the corsair equivalent though. it would be nice to see coolermaster just go the extra step with the water block.

1 out of 5 eggsQuestionable fitting

This review is from: Cooler Master Nepton 280L – All-In-One CPU Liquid Water Cooling System with 280mm Radiator and 2 JetFlo Fans

Pros: Large 140.2mm radiator
Two high speed, high static pressure fans included

Cons: The screws included to hold the radiator in place,on the side with no fans, do NOT have big enough heads. They were also too short for my case.

Either this radiator uses non-standard 280mm mount points or this just does not fit with my case. The top mounting holes only align with 4 of the 8 top fan holes. The other four are forward of the holes by like 1/4"

Other Thoughts: Case - Corsair C70

Manufacturer Response:

5 out of 5 eggsWorks as described

This review is from: Cooler Master Nepton 280L – All-In-One CPU Liquid Water Cooling System with 280mm Radiator and 2 JetFlo Fans

Pros: Keeps temps below 40 degrees Celsius running games while overclocked. Thick raditator, and powerful fans.

Cons: Fans are pretty loud, but easily controlled by cpu fan header. Had to connect pump to a random header on the mother board to get it to run above 0 Rpms for some reason, but it was probably just my motherboard itself.
