Cooler Master Nepton 280L All-In-One Water Cooling System Review


Installation was easy but the options are limited.

Most casings would have difficulty fitting the 280L due to the thickness, often conflicting with the motherboard mounting.

I have the HAF XB that seems to fit the 280L but it wasn’t opened at the time of the review, so I just tested it with the radiator placed on top of another casing.

The Verdict

The Nepton 280M is huge and at full speed it’s noisier than a screaming banshee as it’s using 2 units of 140mm JetFlo fan from Cooler Master.

I think what’s disappointing is that it’s priced at around RM 400 bulky and doesn’t perform that much better than many air coolers, even the Seidon 120M proves to be of better value due to the size, price and casing compatibility.

In short – the 280M is not impressive and certainly not worth spending the amount of money for.
