Cooler Master is known in the enthusiast community for their innovative designs with product offerings ranging from cases to desktop and laptop cooling implements. Cooler Master also offers their own line of all-in-one (AIO) CPU liquid cooling solutions for better system performance without the noise of a typical air cooler. With their Nepton 240M cooler, they enhanced the existing design of their previous AIO products, optimizing its performance with an enhanced pump and radiator design. We measured the unit's performance against that of other high-performance liquid and air coolers to best illustrate its abilities. The Nepton 240M's premium performance comes with a premium price, at a $139.99 MSRP.

The Nepton 240M AIO liquid cooler features a 240mm aluminum-finned radiator tied to a base unit consisting of a 120 liter per minute pump and a micro-finned copper base plate. Unlike the Glacer model, the Nepton 240M does not feature the ability to drain and refill the unit. Cooler Master designed the Nepton 240M with a 27mm deep, 2x120mm copper radiator with brass internal channels, bundled with two of its 120mm Silencio model fans. The Silencio fans are optimized for low noise and high pressure, perfect for use with a liquid cooling radiator. The radiator and unit base are connected by ribbed FEP (Fluorinated Ethylene Propylene) tubing, allowing for high flexibility without the worry of tube kinking.

The unit's base block consists of a copper water block mounted to an acrylic housing for the pump and unit electronics. The pump direct mounts to the housing with flow directed through the micro-fin channels integrated into the base plate. Both integrated barbs in the CPU block are 90 degree barbs and allow for a full 360 degree rotation.

Were you able to tell if the holes stripped easily? From my experience, even hand tightening the screws will strip the holes on the radiator.

Didn't have issues with the radiator fan screw holes....

Is this a bot? Every post is exactly the same: baseless insulting of whatever company was being mentioned, in favor of some other "godly" alternative. I just wonder why someone would take the time to produce a shitposting bot.

That's truly hilarious to read, coming from a typical 4channer kindergarten troll that uses "Anonymous" nickname on this site. Scram already, kiddo.

Excellent review as always Morry! Under pricing you have Cooler Master Glacer 240L listed with links to the 240M

Please review the thermaltake 360 mm Ultimate 3.0,
plus I would love to see a rig with noctua premium fan difference for the whole rig, I have seen upto 5 degrees lower and at lower power and less noise.

I second the excellent review, keep up the good work Morry :)

If you have a case that can at least support the size of a noctua u14 cooler than paying more for an AIO water cooling solution is foolish. The u14 tests within 1-2 degrees of the big d15 and the d15 hangs right in with the water cooling at a much quieter and cheaper price and the u14 is only 75 dollars.
