The Cooler Master neptun 280l continues
a happy Trend that we've seen developing recently it takes the status quo that is
radiators designed for 120 mm fans and
amps it up a notch it uses two 14mm
Cooler Master jet flow fans to cover the massive surface area of its 280 mm long
radiator speaking of status quo instead of rebranding a design from Acer coolit
Cooler Master uses their own pump and an ultra fine microchannel water block
design giving them full control over the performance and quality of these
components but does it translate into the real world I guess we'll find
out with its Factory tuning and data center DNA an Intel 730 series SSD is an
amazing choice for gamers and performance enthusiasts so I'm going to
start this off with a couple of things that I actually don't really like about
this they're jet flow fans have great specs but and this goes for all liquid
cooling manufacturers why do they have rounded
frames see this Gap see this Gap right
here we did a test on another liquid cooler that uses pressure optimized
round frame fans where we use duct tape to cover the gaps and guess what we got
a couple degrees lower temperatures for our effort because duct tape for sealing
gaps to achieve optimal air flow please no gaps please Cooler Master and
everyone else for that matter square frame fans for radiators that is lonus
law number 347 anyway there's another one use of an
all aluminum radiator is something that hardcore liquid cooling purists might
not like but the system is completely sealed and uses extra thick Fe tubing 38
inch tubing by the way to prevent the slow evaporation that can occur with
porous tubing so since you'll never open it and there's an appropriate
anti-corrosive coolant inside it won't be a problem because the metals aren't
actually in contact with each other while it isn't a problem however it does
mean that some of the performance of the system is left on the table compared to
if it had the surface area it does and used a copper and brass design like
cooler Master's own Glacier 240l which performs similarly and also happens to
be fully expandable I apologize in advance for not having it in our
performance charts though I stole it from Luke's testing stable because I
wanted it for my liquid cooling video card test bench sometime ago anyway
about the aluminum rad I'll say this though at least Cooler Master doesn't
hide it I couldn't find the radiator material of the h110 anywhere in
Corsair's official literature and had to go hunting to see what they were using
installing the 280l in my standard case the C70 was actually a little bit tricky
The Fill Point sticks out on the bottom if you don't put the fans on the bottom
and that makes it so that you're probably going to hit your 8 Pin power we actually split that into a four pin
and allowed it to dodge the fill Port which helped a lot but then again in
their recommended configuration with the fans on the bottom not the fans on the
top like we do it it fits a lot better we also had problems with the radiator
hitting other different parts of the case but again if you put the fans on
the bottom like they recommend you don't have that problem although we do prefer
putting it on top we do this with every single radiator that comes in here and
we find that it standardizes the whole process in terms of performance we found
that the cooler performs within margin of error of an h110 and considering the
the the margin of error that comes with our thermal test bench as we don't have a thermally controlled room it's fairly
realistic as these radiators are quite similar so in conclusion if you're
looking for a liquid cooling unit that's got good looks with its wi LED lighting
FX comes with a fantastic 5-year warranty and features compatibility for
both 140 mm and 120 mm fans although the
120 mm fans will seal even less against
the radiator then the nepton 280l is a solid Choice compared to the more
traditional dual 120 mm radiator designs

you missed it before yes that is the difference in size between dual 140 mil
and dual 120 mil it doesn't sound like that much it sounds like 20
mil which could be volume 20
