00:00:07,759 --> 00:00:17,680
welcome to another unboxing online as Tech tips this is the alpha cool NV XP

2
00:00:13,639 --> 00:00:22,240
NVIDIA GTX 670 stainless steel polished

3
00:00:17,680 --> 00:00:24,960
water block from alpha cool pretty much

4
00:00:22,240 --> 00:00:31,000
this is what we're planning to use on our uh on our bit Phoenix liquid cooled

5
00:00:28,199 --> 00:00:34,920
machine so we're going to use a GTX 670 and this Alpha cool Block in order to

6
00:00:33,239 --> 00:00:40,600
achieve the cooling performance that we need in a small form factor liquid

7
00:00:37,760 --> 00:00:45,680
cooled machine the thing about the 670 is it's such a low profile video card

8
00:00:43,239 --> 00:00:51,559
that it is perfect for a lowprofile liquid cooling installation so you might

9
00:00:48,960 --> 00:00:57,520
have noticed that compared to my standard HTC 8X phone size comparison

10
00:00:55,280 --> 00:01:02,079
that I've never done before now or maybe once before now that this is not a huge

11
00:01:00,280 --> 00:01:08,240
water block and the reason for that is the 670 appears to be a large graphics

12
00:01:04,920 --> 00:01:11,880
card at first but when you turn it

13
00:01:08,240 --> 00:01:13,479
around it actually has like an extension

14
00:01:11,880 --> 00:01:16,799
that's only made of plastic I'll get slick to come in and have a look at this

15
00:01:14,920 --> 00:01:22,040
first an extension that's only made of plastic that goes beyond the size of the

16
00:01:19,040 --> 00:01:24,280
PCB here so this block is a perfectly

17
00:01:22,040 --> 00:01:28,960
appropriate size for this particular card that makes sense to

18
00:01:26,360 --> 00:01:34,000
you so why did we decide to go with this one well availability helps and Alpha

19
00:01:31,640 --> 00:01:38,640
cool has been around a long time making water cooling gear so let's just go

20
00:01:37,079 --> 00:01:42,119
ahead and see if I can figure out how like why do they do this look at this it

21
00:01:40,439 --> 00:01:48,479
comes in like a food package see it's like uh it's like

22
00:01:44,840 --> 00:01:51,079
vacuum sealed so just just slice that oh

23
00:01:48,479 --> 00:01:53,719
okay yeah it's all good um I mean I think I can think of one reason it's

24
00:01:52,560 --> 00:01:57,680
going to prevent the Copper from oxidizing if they have it sealed up like

25
00:01:55,960 --> 00:02:04,920
this cuz one of the things that drives me crazy about Co blocks is oxidized

26
00:02:03,039 --> 00:02:12,479
ugly stained copper so I'm going to be extremely careful not to oh that's going

27
00:02:07,600 --> 00:02:12,479
to be hard um yep I have a

28
00:02:13,599 --> 00:02:19,560
solution gloves um I love the look of

29
00:02:17,440 --> 00:02:23,160
copper I hate the look of stained oxidized ugly copper so we're going to

30
00:02:21,920 --> 00:02:27,319
go ahead and put on some gloves to handle this I would highly recommend

31
00:02:25,040 --> 00:02:33,160
that you do the same thing it's not because of any sort of fault in fact the

32
00:02:30,519 --> 00:02:37,400
more pure the copper being used by the manufacturer the better the chance that

33
00:02:35,480 --> 00:02:41,680
it will be easily stained and look horrific after a little while so the top

34
00:02:40,120 --> 00:02:45,440
is a polish stainless steel although it's available in a variety of finishes

35
00:02:43,400 --> 00:02:50,760
so you can see how reflective that is we're going to see if we can catch slick

36
00:02:47,680 --> 00:02:53,920
in the reflection diesel am I

37
00:02:50,760 --> 00:02:57,360
close I got

38
00:02:53,920 --> 00:02:59,480
him yes there we go that is how

39
00:02:57,360 --> 00:03:05,319
reflective the top of this block is it's actually only a very very slim layer of

40
00:03:03,640 --> 00:03:10,120
stainless steel covering the top of the block and it's two separate pieces of

41
00:03:07,799 --> 00:03:15,159
copper here that make up the overall construction so you can also see they're

42
00:03:11,879 --> 00:03:17,040
using Len key uh screws to hold the

43
00:03:15,159 --> 00:03:22,280
whole thing together very very securely I mean these are pressure tested um so

44
00:03:19,959 --> 00:03:25,360
yeah now this is a bit of a unique thing so they're actually using a little bit

45
00:03:23,799 --> 00:03:30,720
less material to make up the block itself here it used to be that you'd see

46
00:03:28,120 --> 00:03:34,080
um the threads themselves made out of whatever material the block is in this

47
00:03:32,200 --> 00:03:39,959
case copper but what they've done is they've actually expanded the area here

48
00:03:37,120 --> 00:03:43,720
by putting like a threaded piece through it so that's sort of a unique approach

49
00:03:42,040 --> 00:03:46,920
it looks like it allows them to save on some of the cost of the block but it

50
00:03:45,120 --> 00:03:52,159
shouldn't affect performance and it shouldn't affect the ability of the

51
00:03:48,599 --> 00:03:53,879
block to uh to accept larger threaded uh

52
00:03:52,159 --> 00:03:57,400
fittings so that was a that was a big problem for a while is some fittings

53
00:03:55,200 --> 00:04:01,319
like the older dtec barbs had threads that were like this long and people were

54
00:03:59,159 --> 00:04:03,840
putting them through full cover blocks and they were going almost all the way

55
00:04:02,599 --> 00:04:08,280
through to where the other fitting would go on the other side and they were leaking CU they weren't going in all the

56
00:04:06,400 --> 00:04:11,560
way so that's uh that's not going to be a problem with this one thing to be

57
00:04:09,840 --> 00:04:14,959
careful of with these water blocks is you want to make sure that you have a

58
00:04:13,200 --> 00:04:19,320
reference card so here they're giving you a little guidance thing for making

59
00:04:17,280 --> 00:04:23,919
sure that your card is actually compatible with the block before you get

60
00:04:21,880 --> 00:04:28,080
started so you can see right here all the places where you need to apply

61
00:04:25,479 --> 00:04:35,039
thermal pads so here for memory and memory here for the GPU itself and here

62
00:04:30,199 --> 00:04:37,400
for the vrm and um let's see what else

63
00:04:35,039 --> 00:04:40,120
we got here ah yes their whole copper theme thing that I think is freaking

64
00:04:38,919 --> 00:04:45,840
awesome so here's some more thermal compound that's going to be for the GPU core itself you won't use a thermal pad

65
00:04:43,199 --> 00:04:50,199
for that and then copper Stoppers um I would probably go ahead and use nickel

66
00:04:48,039 --> 00:04:53,880
plated Stoppers just because that'll be more consistent with the overall look

67
00:04:51,720 --> 00:04:58,639
that I'm going for in my build but I think that pretty much covers it don't
