Cooler Master Nepton 240M Review

Conclusion

A quick look at the performance and testing page tells the story of the Cooler Master 240M and it's fair to say we didn't get the results we were hoping for.  It all started off well enough, but our hopes for the 240M were dashed on the rocks of reality when we started cranking the voltage up.  As things got hotter the 240M basically failed to cope in any way, shape or form, and began its slide down the charts.  So sure were we that it should have done better that we actually re mounted it and repeated all the testing, but alas the results we gained the first time were essentially repeated all bar a fraction of a degree here or there, and not always in its favour.

We're not exactly sure why the 240M has done so badly, but it's not the first 240mm Radiator based cooler from Cooler Master that has failed to impress us. (Yes, we're looking at you Eisberg series).  However we thought it might be an idea early on in the conclusion to compare the Nepton 240M to some of its immediate competition, and in doing so, it's the H100i from Corsair that springs most readily to mind, the radiators are almost the same size, bar a coat of paint, and with all other things being equal they should have very similar performance.  Thing is, they don't.  The 240M isn't even close to the H100i.  We could lay the blame at the feet of the Cooler Master fans, they have a lower RPM than the Corsair units, but stated figures from both manufacturers have them at about the same airflow but with a slightly higher static pressure from the Nepton, so maybe it's not the fans fault.  Perhaps then it could be the cold plate, the Cooler Master unit is an in house design which is intended to maximise cooling potential, however, it just might be the case that they've tried to fix something that wasn't that broken in the first place and not done it any good in the process.  Then of course there's the density of the fins in the radiator to be considered.  If you remember we noted at the start of the review that although the fins were perfectly formed, we thought the fin density was actually quite low, with us able to photograph straight through them.  This then could be the culprit, however, it turns out that the 240M has 21 fins per inch and 12 channels, which is to all intents and purposes the same as the H100i which coincidently shares the same 27mm thickness of radiator, and uncannily similar to the Seidon 240 which actually appears to have an identical radiator to the Nepton 240M.  In reality what is causing the poor performance is of little consequence.  It could be one of many factors we've not even begun to touch on.  What is important is that as AIOs go it's not high on our shopping list.  Granted quality is good, but no better than the competition, and although the 240M does have a light up logo, there's no RGB functionality enabling you to change the lighting theme as there is with elements of the competition, neither do you get the facility to monitor and control the Nepton via USB and linked software, as is the case with others.  To top it all off, we can't even say the 240M is well priced and despite its failings is cheaper as in fact it rocks up at about the same price give or take a quid or two as the 1H100i and the H105.

Sorry Cooler Master, we loved the 280L and the performance it offered, but the Nepton 240M just doesn't cut the mustard and because of this we have decided not to award the 240M at all. There are too many better options in all respects around the same price and quite often....Less. Take our advise and stick to the old faithful Corsair H100i or give our review of the Fractal S24 a look.

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.Quote

I've watched some reviews of the 240M and I was looking for one to buy (based on the reviews I watched ), I guess it's good, I didn't find one, so I went with the 100i.Quote
