The Nepton 240M is a 240mm radiator based AIO with some rather nice little features, but how will it fare in the torture tests?

Cooler Master Nepton 240M Review

Wow I didn't expect that, who am I kidding it's a CM "M" series AIO, they all suck, of cause they will later release a "V" version and temporarily redeem their honor then follow it up with another "L" this seems to be the case time and again for CM. This was painful to see especially as it gets a whooping from a Air cooler, OK it's the D15 but still a 240mm AIO being out classed by air. Poor show Cooler Master.

Quite a few 240 AIOs are on par with the D15. Its a beast.
 
I've watched some reviews of the 240M and I was looking for one to buy (based on the reviews I watched :confused: ), I guess it's good, I didn't find one, so I went with the 100i.
 
Thats a real letdown considering cooler master was slowly improving their AIO lineup and slowly climbed up the ranks, but then this.
 
Agreed! To be on par or a knats in front is ok but the 240m got spanked in those graphs.


When looking at those graphs there are a few other coolers that perform worse then expected. The two that pop out the most are CM Eisberg and Swiftech H220. On all other reviews I have read they are the best performing 240mm AIOs, sometimes even beating the 280mm competition. But here they are more or less the middle of the pack.
The biggest difference being OC3D is using lga 2011 with extreme i7s while most other reviewers are using "normal" i7s on lga 1150.

So my question would be is there some thermal limit those coolers hit and after that their performance plummets, because that is the only explanation I can think of? Unless they just refuse to work well on lga 2011 :headscratch:

Basically we have kept the 2011 rig to stress everything to within an inch of its life - like a worst case scenario. Thats why we ignore people that says "such and such a review said it was 5c lower" unless its on our rig you cant compare it.
 
Only AIO I would love to see an OC3D torture review is the Raijintek Triton.
I mean that thing is 25 euros cheaper than an h100i + modular
 
You wont have to wait long but the modular isnt a + point for us

I would say that any modular *AIO*ish would be a good thing IF it is well made. As the possibilities to fit it in any small form factor would be a great help as you dont have to think where your pump and res would have to be.
 
I recently picked up the Nepton 240M. Although Tom recommended the Kelvin S24 over the Nepton, I was put off by the negative reviews concerning its pump and the compatibility with RAM. Also, the numbers between the S24 and the Nepton 240M were not that big anyway. If the Corsair H100i GTX had been available at the time and this review had been out, I would have bought it, but sadly it wasn't—I didn't even know it existed. Or if I had known the Nepton would have been this troublesome, I may have invested in the Swiftech H220X and put up with its ugly ass.

As a whole, I am somewhat disappointed with this cooler and probably should have stuck with big air. I think the performance you gain and the better aesthetics are not enough to warrant the hassle of installation and the noise of the pump. My case couldn't fit a 280mm radiator or anything larger and the original H100i did not interest me at all. From that standpoint, I should have picked up a better air cooler. For instance, the Cryorig R1 Universal would have suited my white/black themed build, but again, I didn't know it existed until after purchasing the Nepton, and I'm past the 30-day money back guarantee now. Plus, my motherboard was damaged somehow from installing the Nepton and I had to replace it. Everything that could have went wrong, went wrong.

Although the numbers are perfectly fine and the noise of the fans is low, the pump had collected all the air bubbles and was driving me insane. After talking with Cooler Master customer support, I eventually silenced the bulk of the noise after many re-installations and a whole tube of €10 thermal compound. Although the pump is still audible, it is not as annoying any more. I'll put up with it for now, but when I upgrade next time, I'll keep this fucker as a backup cooler (even though it's a bitch to install) and go back to big air or buy a Swiftech H240X for its silence and performance or a H110i GT for its aesthetics and performance.
