1
00:00:00,400 --> 00:00:09,200
the Noctua nhd14 widely regarded as one of if not the

2
00:00:06,799 --> 00:00:15,360
best air cooler on the market this is a six heat pipe dual tower cooler that

3
00:00:12,080 --> 00:00:18,320
includes a 140 millimeter fan in the

4
00:00:15,360 --> 00:00:22,800
center between the two towers a 120 millimeter fan on the outside of one of

5
00:00:20,240 --> 00:00:27,760
the towers and then should you show so desire i believe you can actually

6
00:00:24,320 --> 00:00:29,519
install an additional 120 millimeter fan

7
00:00:27,760 --> 00:00:33,520
on the other tower so this isn't a push pull kit well rather

8
00:00:31,199 --> 00:00:38,879
push pull push configuration because this one's doing pushing and pulling

9
00:00:35,120 --> 00:00:41,840
through radiator or heat sink fins

10
00:00:38,879 --> 00:00:45,360
and uh down here make contact with the CPU somewhere in there you can see that

11
00:00:43,520 --> 00:00:52,399
they've cleverly designed the height to be just barely acceptable for high

12
00:00:50,480 --> 00:00:56,559
high profile memory modules such as the mushkin

13
00:00:53,520 --> 00:00:59,280
red lines that i am using here today

14
00:00:56,559 --> 00:01:06,159
all right so i have for the longest time wanted to test this CPU heatsink against

15
00:01:03,120 --> 00:01:09,360
this CPU liquid cooling unit so this is

16
00:01:06,159 --> 00:01:12,240
the Corsair h70 it is a high fin density

17
00:01:09,360 --> 00:01:17,600
high thickness single 120 millimeter radiator liquid cooling system so i can

18
00:01:15,280 --> 00:01:22,400
tell you guys right now any thin low profile radiators uh system such as a

19
00:01:19,840 --> 00:01:26,400
cooled eco or an h50 is going to get smoked by this bad boy i mean it's

20
00:01:25,040 --> 00:01:32,159
fairly simple science at this point more surface area

21
00:01:29,840 --> 00:01:36,159
far less surface area for the uh for the thin profile

22
00:01:33,759 --> 00:01:40,159
radiator liquid cooling units so that's that ain't going to happen for them but

23
00:01:37,920 --> 00:01:43,439
the h70 might stand a chance so what i'm going to be doing today

24
00:01:41,840 --> 00:01:50,560
is i'm going to take the h well first i'm going to test the nhd14 on my 4.7

25
00:01:46,240 --> 00:01:53,200
gigahertz uh core i7 2600k this is with

26
00:01:50,560 --> 00:01:56,560
a fair over fair bit of over voltage so we've got a fair bit of heat to

27
00:01:54,479 --> 00:02:02,719
dissipate here i'm going to first test the nhd14 in its stock configuration

28
00:01:59,360 --> 00:02:04,360
then i'm going to take this 120mm fan

29
00:02:02,719 --> 00:02:10,560
another nfp12 i believe it is a 1300 or whatever

30
00:02:07,600 --> 00:02:12,480
it's called the the 1 1300 RPM um

31
00:02:11,440 --> 00:02:18,640
pressure span so the one with the blades like that not the other one and i'm going to

32
00:02:15,840 --> 00:02:22,959
install two of those on the h70 and see how it performs compared to the

33
00:02:20,840 --> 00:02:27,760
nhd14 i'm very excited about this because the ah 70 is the highest

34
00:02:24,879 --> 00:02:32,879
performance single 120 millimeter liquid cooling pre-filled unit and the nhd14 as

35
00:02:30,959 --> 00:02:37,280
i mentioned before is one of the highest performing air coolers on the market so

36
00:02:35,200 --> 00:02:40,720
let's see which one wins in this heavyweight tilt

37
00:02:38,800 --> 00:02:47,200
so here i am running eight instances of prime95 on my core i7 2600k so my max

38
00:02:44,480 --> 00:02:52,640
core temperature is 74 degrees and the minimum one is 68 so we're going to call

39
00:02:49,120 --> 00:02:53,519
it sort of somewhere in that 68 to 75

40
00:02:52,640 --> 00:02:57,599
now 68 to 75 degree range

41
00:02:58,080 --> 00:03:03,760
on the nh d14

42
00:03:01,360 --> 00:03:09,440
so i just put the h70 with the two Noctua fans onto the CPU you can see

43
00:03:06,640 --> 00:03:14,319
temperatures are a touch higher already and you have to note that unlike an air

44
00:03:11,840 --> 00:03:19,280
cooler where the heat pipes basically reach their maximum temperature heat

45
00:03:16,400 --> 00:03:24,000
carrying efficiency etc right off the bat a liquid cooling unit actually takes

46
00:03:22,080 --> 00:03:27,200
a while to reach equilibrium where the liquid inside has to heat up to the

47
00:03:25,920 --> 00:03:32,720
point where it increases the efficiency with which the

48
00:03:30,959 --> 00:03:36,159
radiator can exchange the heat between the water and the air

49
00:03:34,480 --> 00:03:39,519
and the higher the temperature of the liquid inside the more heat is able to

50
00:03:37,760 --> 00:03:44,879
be exchanged until it reaches a point where it no longer continues to rise

51
00:03:42,400 --> 00:03:48,000
with a constant heat load so i'm going to give it some time to see

52
00:03:46,480 --> 00:03:53,280
how high it goes but i think we can already see that the d14 comes out ahead

53
00:03:50,959 --> 00:03:56,959
with the same fans all right well looks like we've settled into a max

54
00:03:54,640 --> 00:04:01,840
temperature here 88 degrees on the highest core 81 degrees on the lowest

55
00:03:59,519 --> 00:04:06,319
core running prime95 eight instances of small fft

56
00:04:04,319 --> 00:04:12,000
