00:00:00,280 --> 00:00:05,440
The Cooler Master neptun 280l continues

2
00:00:03,399 --> 00:00:12,360
a happy Trend that we've seen developing recently it takes the status quo that is

3
00:00:08,519 --> 00:00:16,640
radiators designed for 120 mm fans and

4
00:00:12,360 --> 00:00:19,000
amps it up a notch it uses two 14mm

5
00:00:16,640 --> 00:00:25,039
Cooler Master jet flow fans to cover the massive surface area of its 280 mm long

6
00:00:22,400 --> 00:00:30,080
radiator speaking of status quo instead of rebranding a design from Acer coolit

7
00:00:27,480 --> 00:00:33,960
Cooler Master uses their own pump and an ultra fine microchannel water block

8
00:00:32,040 --> 00:00:37,360
design giving them full control over the performance and quality of these

9
00:00:35,280 --> 00:00:41,600
components but does it translate into the real world I guess we'll find

10
00:00:45,680 --> 00:00:53,440
out with its Factory tuning and data center DNA an Intel 730 series SSD is an

11
00:00:51,600 --> 00:00:57,520
amazing choice for gamers and performance enthusiasts so I'm going to

12
00:00:55,800 --> 00:01:02,640
start this off with a couple of things that I actually don't really like about

13
00:00:59,719 --> 00:01:07,280
this they're jet flow fans have great specs but and this goes for all liquid

14
00:01:06,040 --> 00:01:14,040
cooling manufacturers why do they have rounded

15
00:01:10,240 --> 00:01:16,759
frames see this Gap see this Gap right

16
00:01:14,040 --> 00:01:21,560
here we did a test on another liquid cooler that uses pressure optimized

17
00:01:19,040 --> 00:01:26,079
round frame fans where we use duct tape to cover the gaps and guess what we got

18
00:01:23,680 --> 00:01:31,600
a couple degrees lower temperatures for our effort because duct tape for sealing

19
00:01:29,000 --> 00:01:35,640
gaps to achieve optimal air flow please no gaps please Cooler Master and

20
00:01:33,520 --> 00:01:39,840
everyone else for that matter square frame fans for radiators that is lonus

21
00:01:38,600 --> 00:01:45,640
law number 347 anyway there's another one use of an

22
00:01:43,079 --> 00:01:50,719
all aluminum radiator is something that hardcore liquid cooling purists might

23
00:01:47,759 --> 00:01:56,000
not like but the system is completely sealed and uses extra thick Fe tubing 38

24
00:01:54,320 --> 00:02:01,200
inch tubing by the way to prevent the slow evaporation that can occur with

25
00:01:58,520 --> 00:02:04,840
porous tubing so since you'll never open it and there's an appropriate

26
00:02:02,520 --> 00:02:08,119
anti-corrosive coolant inside it won't be a problem because the metals aren't

27
00:02:06,360 --> 00:02:12,080
actually in contact with each other while it isn't a problem however it does

28
00:02:10,080 --> 00:02:17,599
mean that some of the performance of the system is left on the table compared to

29
00:02:14,959 --> 00:02:22,760
if it had the surface area it does and used a copper and brass design like

30
00:02:19,920 --> 00:02:27,400
cooler Master's own Glacier 240l which performs similarly and also happens to

31
00:02:25,040 --> 00:02:30,599
be fully expandable I apologize in advance for not having it in our

32
00:02:28,640 --> 00:02:33,800
performance charts though I stole it from Luke's testing stable because I

33
00:02:32,280 --> 00:02:38,319
wanted it for my liquid cooling video card test bench sometime ago anyway

34
00:02:36,400 --> 00:02:42,120
about the aluminum rad I'll say this though at least Cooler Master doesn't

35
00:02:40,159 --> 00:02:45,800
hide it I couldn't find the radiator material of the h110 anywhere in

36
00:02:44,200 --> 00:02:50,560
Corsair's official literature and had to go hunting to see what they were using

37
00:02:48,280 --> 00:02:55,040
installing the 280l in my standard case the C70 was actually a little bit tricky

38
00:02:53,200 --> 00:02:58,080
The Fill Point sticks out on the bottom if you don't put the fans on the bottom

39
00:02:57,000 --> 00:03:03,879
and that makes it so that you're probably going to hit your 8 Pin power we actually split that into a four pin

40
00:03:01,800 --> 00:03:08,080
and allowed it to dodge the fill Port which helped a lot but then again in

41
00:03:05,879 --> 00:03:12,799
their recommended configuration with the fans on the bottom not the fans on the

42
00:03:10,080 --> 00:03:15,560
top like we do it it fits a lot better we also had problems with the radiator

43
00:03:14,319 --> 00:03:19,720
hitting other different parts of the case but again if you put the fans on

44
00:03:17,840 --> 00:03:23,159
the bottom like they recommend you don't have that problem although we do prefer

45
00:03:21,640 --> 00:03:26,879
putting it on top we do this with every single radiator that comes in here and

46
00:03:24,920 --> 00:03:30,840
we find that it standardizes the whole process in terms of performance we found

47
00:03:28,920 --> 00:03:36,080
that the cooler performs within margin of error of an h110 and considering the

48
00:03:34,640 --> 00:03:42,040
the the margin of error that comes with our thermal test bench as we don't have a thermally controlled room it's fairly

49
00:03:39,680 --> 00:03:46,439
realistic as these radiators are quite similar so in conclusion if you're

50
00:03:44,680 --> 00:03:51,360
looking for a liquid cooling unit that's got good looks with its wi LED lighting

51
00:03:48,879 --> 00:03:58,200
FX comes with a fantastic 5-year warranty and features compatibility for

52
00:03:53,560 --> 00:04:01,200
both 140 mm and 120 mm fans although the

53
00:03:58,200 --> 00:04:03,799
120 mm fans will seal even less against

54
00:04:01,200 --> 00:04:09,000
the radiator then the nepton 280l is a solid Choice compared to the more

55
00:04:05,519 --> 00:04:11,319
traditional dual 120 mm radiator designs

56
00:04:09,000 --> 00:04:16,320
on the market just make sure that your case has room for it guys like this

you missed it before yes that is the difference in size between dual 140 mil

71
00:05:11,639 --> 00:05:20,240
and dual 120 mil it doesn't sound like that much it sounds like 20

72
00:05:15,680 --> 00:05:20,240
mil which could be volume 20
