1
00:00:00,640 --> 00:00:06,600
this is the hr2 it is big and heavy and

2
00:00:04,040 --> 00:00:12,280
it is made by thermal right they are advertising this as a fanless CPU Cooler

3
00:00:10,440 --> 00:00:17,760
so they're saying that you can actually run many of today's modern high

4
00:00:14,759 --> 00:00:19,199
performance CPUs fanless completely

5
00:00:17,760 --> 00:00:22,880
passive as long as you have some case air flow with this particular heat sink

6
00:00:21,240 --> 00:00:28,400
so let's take a look at it the first thing we find is a thermal rate sticker

7
00:00:25,640 --> 00:00:32,239
then we have an installation guide which shows us a view of how to to uh attach

8
00:00:30,800 --> 00:00:41,160
all of the different mounting brackets it does include mounting for uh 775

9
00:00:36,320 --> 00:00:43,000
1366 1156 as well as am2 as I recall uh

10
00:00:41,160 --> 00:00:46,960
let me just uh we'll double check that when we get to the actual Hardware okay

11
00:00:44,920 --> 00:00:50,559
so here's the included mounting hardware you can see this is clearly for am2 and

12
00:00:49,239 --> 00:00:54,559
then this is clearly a multi- installation kit for Intel all right

13
00:00:53,280 --> 00:01:00,719
let's see what we got for look at this it comes with a screwdriver check that

14
00:00:56,920 --> 00:01:03,479
out Chrome vadium okay I don't actually

15
00:01:00,719 --> 00:01:09,240
know how to pronounce that vadium vadium neat it's a screwdriver magnetic

16
00:01:07,400 --> 00:01:12,799
hey it's magnetic too look at that do we have anything to test it on around here

17
00:01:11,240 --> 00:01:19,600
okay here here yeah yeah here's a PCI back

18
00:01:14,840 --> 00:01:21,040
plate it's not very magnetic okay well

19
00:01:19,600 --> 00:01:27,360
that's okay you still get a free screwdriver with your heat sink purchase

20
00:01:23,560 --> 00:01:27,360
that is a compelling bundle

21
00:01:27,720 --> 00:01:35,920
offering okay mounting hardware I'm going to need my handy dandy Tech tips

22
00:01:32,399 --> 00:01:39,399
knife which I now actually have there we

23
00:01:35,920 --> 00:01:41,479
go that is officially open now so in

24
00:01:39,399 --> 00:01:46,399
here we will find a variety of things we've got some rubber grommets we have

25
00:01:43,759 --> 00:01:50,119
some fan Clips we have some thermal compound

26
00:01:47,840 --> 00:01:54,759
cf3 next we have a wrench you got a wrench and a screwdriver you get like a

27
00:01:52,200 --> 00:02:00,520
tool kit with this thing and then we have the am2 mounting hardware also am3

28
00:01:57,719 --> 00:02:07,520
and then we have the uh multi back for Intel so uh here yeah 775 1156 and

29
00:02:05,560 --> 00:02:11,640
1366 all right let's look at the heat sink itself since that's the most

30
00:02:09,039 --> 00:02:14,800
interesting part of this video other than me of

31
00:02:12,680 --> 00:02:19,000
course no I'm kidding I know the heat sink's the most interesting part so this

32
00:02:17,519 --> 00:02:25,080
is the H2 and it has a couple of unique Design

33
00:02:22,599 --> 00:02:31,360
Elements so we'll get started here once I finally have it out of the

34
00:02:27,480 --> 00:02:34,120
bag that thing is H huge so first of all

35
00:02:31,360 --> 00:02:40,159
it has a boatload of heat pipes you can see it's actually got six full u-shaped

36
00:02:37,040 --> 00:02:42,200
heat pipes so that's almost 12 effective

37
00:02:40,159 --> 00:02:46,920
heat pipes when you look at how they're all attached to the base it's a very

38
00:02:44,280 --> 00:02:50,080
very shiny flatl looking base and we'll do the obligatory finger shot that

39
00:02:48,680 --> 00:02:55,000
everyone in their dog seems to be determined to complain about but I don't

40
00:02:51,920 --> 00:02:57,640
really care all right so you can see

41
00:02:55,000 --> 00:03:02,159
first of all that this heat sink has a very very wide spacing for the fins

42
00:02:59,959 --> 00:03:06,319
that's because it does rely on passive cooling so that means when this is

43
00:03:03,519 --> 00:03:11,879
installed on your socket okay so let's say hypothetically it's installed like

44
00:03:08,120 --> 00:03:13,599
this it relies on the heat that is

45
00:03:11,879 --> 00:03:18,640
generated by the heat pipes transferring heat to the fins to Simply heat the air

46
00:03:16,519 --> 00:03:24,799
and then the air will rise out of it or be pulled Slowly by a case fan and

47
00:03:22,760 --> 00:03:28,519
that's it that's the only Force you have so that's why the fins need to be spaced

48
00:03:26,760 --> 00:03:32,959
really wide so that it doesn't take a lot of pressure to push the air through

49
00:03:30,519 --> 00:03:38,159
it now besides the wide spacing of the fins you can see what thermal R's done

50
00:03:35,280 --> 00:03:40,760
is they've actually used their little um I don't know if they actually even have

51
00:03:39,360 --> 00:03:46,360
a name for this but what they've done is they've cut little holes and bent up the flaps in every one of the aluminum

52
00:03:44,280 --> 00:03:50,040
layers here and that gives us just a little bit more surface area so based on

53
00:03:48,439 --> 00:03:54,360
that so you can see that's all the way through the heat sink I would probably

54
00:03:51,879 --> 00:03:59,360
recommend mounting this heat sink this way either this way or this way because

55
00:03:58,120 --> 00:04:03,480
that's going to mean that I mean heat rises so it means that you're giving the

56
00:04:01,360 --> 00:04:08,200
air less resistance to rise up through the heat sink and cool your CPU now this

57
00:04:06,360 --> 00:04:13,439
hole right here is probably why you need the screwdriver that's how you're going

58
00:04:10,120 --> 00:04:16,479
to uh screw it in if you're using an

59
00:04:13,439 --> 00:04:17,759
am2 uh socket so that's positioned right

60
00:04:16,479 --> 00:04:21,519
there for that and then on the other side you can reach it quite a bit more

61
00:04:19,600 --> 00:04:25,440
easily that's one of the considerations when you're building a heat sink this

62
00:04:22,840 --> 00:04:31,400
big is how do you actually access the mounting hardware and uh so people can

63
00:04:28,960 --> 00:04:36,240
actually attach it to their motherboard cameraman's giving me his iPhone for the

64
00:04:33,680 --> 00:04:42,639
usual scale shot so you can see compared to an iPhone it would crash

65
00:04:39,560 --> 00:04:45,199
it it's quite a bit bigger and heavier

66
00:04:42,639 --> 00:04:48,440
okay so there it is from the side and let's just have a closer look at how

67
00:04:46,560 --> 00:04:53,120
they've attached the uh the heat pipes down here at the bottom so it's six heat

68
00:04:50,400 --> 00:04:57,440
pipes alternating so some of them go over to this side of the heat sink and

69
00:04:55,479 --> 00:05:02,440
the others just go straight up in a straight U shape so all six of them are

70
00:05:00,759 --> 00:05:05,479
aligned at the same level I've actually seen some coolers where some of the heat

71
00:05:04,160 --> 00:05:09,080
pipes are a little bit higher and I don't know what that would do in terms

72
00:05:07,320 --> 00:05:13,160
of thermal transfer but this way they're all as close as possible to the CPU

73
00:05:11,000 --> 00:05:16,960
without touching directly and I think that pretty much covers everything I

74
00:05:14,520 --> 00:05:20,639
wanted to say about the hr2 I'm actually kind of curious to try this one out and

75
00:05:18,520 --> 00:05:26,520
see uh see how well it can do on even like a a core i7 or something like that

76
00:05:22,919 --> 00:05:26,520
it's very heavy though
