1
00:00:07,319 --> 00:00:14,440
so my original hypothesis about my water cooling Loop was that it had gotten all

2
00:00:12,160 --> 00:00:19,480
gunked up due to microbial growth in spite of the fact that I am using

3
00:00:15,960 --> 00:00:21,359
primochill LRT that is oh I can't even

4
00:00:19,480 --> 00:00:26,519
remember what it stands for

5
00:00:24,240 --> 00:00:30,279
um huh well there you go whatever the primochill antimicrobial tubing I

6
00:00:28,599 --> 00:00:33,239
thought it was cuz I reused some of the segments of tubing so they didn't have

7
00:00:31,840 --> 00:00:36,680
the coating enough of a coating left anymore or whatever else but I'm

8
00:00:35,000 --> 00:00:41,399
starting to think it was to do with this block and not anything else because you

9
00:00:38,559 --> 00:00:45,480
can see there's weird text on the other side of the

10
00:00:42,559 --> 00:00:50,320
block see that there's like graphic design going on and it's not on the side

11
00:00:48,039 --> 00:00:55,039
see here you can see under my finger it's on the other side of the Plexi and

12
00:00:53,000 --> 00:01:00,640
this looks like some kind of a corrosion or something see that's not a normal

13
00:00:57,160 --> 00:01:02,399
nickel color so I'm going to be opening

14
00:01:00,640 --> 00:01:08,159
up this block and seeing if I can even clean it off and let's try and find out

15
00:01:05,080 --> 00:01:09,479
what the heck is going on here so my my

16
00:01:08,159 --> 00:01:14,720
new Loop is going to be using a swifttech block so one way or another um

17
00:01:12,880 --> 00:01:19,200
whatever kind of issue I know EK had some nickel plating issues in the past

18
00:01:16,920 --> 00:01:22,840
but I didn't think the GTX 480 blocks were offend were affected so I guess

19
00:01:21,040 --> 00:01:28,320
we're uh we're about to find out all right so the cover has been removed and

20
00:01:26,000 --> 00:01:33,560
it's interesting cuz I can uh I can read the text now so something about Quinn

21
00:01:31,439 --> 00:01:38,799
plastics.com and uh format something these are

22
00:01:37,159 --> 00:01:42,399
another languages but

23
00:01:42,799 --> 00:01:48,360
um that's hilarious so this is just yeah

24
00:01:46,079 --> 00:01:53,439
it's just Gunk see so I can scratch it right off but I guess it was probably

25
00:01:51,399 --> 00:02:00,439
from the protective layer that was over the Plexi before it was applied and that

26
00:01:57,000 --> 00:02:04,640
somehow left um

27
00:02:00,439 --> 00:02:06,479
like a slight residue in the shape of

28
00:02:04,640 --> 00:02:13,720
the text so here there's a phone number so plus 44 028 6774

29
00:02:11,520 --> 00:02:18,200
886 and then I wonder if there's something after that doesn't look like

30
00:02:15,400 --> 00:02:23,360
it so yeah there you go so you can reach Quinn Plastics and ask them about it if

31
00:02:19,840 --> 00:02:25,640
you really want to I suppose um now

32
00:02:23,360 --> 00:02:31,280
let's have a look at the Block itself so this is where we start getting into

33
00:02:27,800 --> 00:02:36,440
whether or not this block is correct

34
00:02:31,280 --> 00:02:36,440
roing I mean that looks an awful lot

35
00:02:37,000 --> 00:02:43,560
like metal discoloration to

36
00:02:40,959 --> 00:02:49,239
me but until I pick away at it a little bit

37
00:02:46,280 --> 00:02:52,400
here I'm not going to know for sure everywhere else kind of looks okay oh

38
00:02:50,920 --> 00:02:56,599
hold on what's that that one's not coming

39
00:02:54,200 --> 00:02:59,280
off here hope you guys can see this I wonder if I can switch to macro mode in

40
00:02:58,000 --> 00:03:06,159
the middle of filming I don't think I can here I'm going to switch to macro mode okay we're in macro mode now so uh

41
00:03:04,280 --> 00:03:10,200
haven't really tried to clean it off yet but there's that one and then here's the

42
00:03:08,239 --> 00:03:13,159
one over here right there that doesn't seem to be coming off so I wonder if

43
00:03:11,799 --> 00:03:17,360
there were some imperfections in the nickel plating here going to try and

44
00:03:15,959 --> 00:03:20,840
clean it off completely now and see what happens going to have to remove the block from the card in order to do that

45
00:03:20,080 --> 00:03:28,120
as well so I'm in the bathroom

46
00:03:24,000 --> 00:03:30,159
now got my uh got my block here got an

47
00:03:28,120 --> 00:03:37,760
old toothbrush that's got some alcohol on it so that

48
00:03:32,760 --> 00:03:40,760
uh might at least help me clear away

49
00:03:37,760 --> 00:03:43,959
some of this Gunk which it doesn't seem

50
00:03:40,760 --> 00:03:47,840
to be doing this is uh this is some

51
00:03:43,959 --> 00:03:51,040
pretty robust Gunk we got going on

52
00:03:47,840 --> 00:03:53,360
here huh it's funny cuz

53
00:03:51,040 --> 00:03:57,079
it oh no that doesn't come off that easily does

54
00:03:54,560 --> 00:04:00,360
it so I was having some success with it before I hope you guys can see what I'm

55
00:03:58,400 --> 00:04:05,239
doing yeah not really okay okay I'll move it a little closer there we go

56
00:04:02,560 --> 00:04:05,239
we'll call that good

57
00:04:06,000 --> 00:04:14,840
enough yeah no that's not coming off at all but if I try with like a little bit

58
00:04:11,799 --> 00:04:14,840
more scrubbing

59
00:04:15,079 --> 00:04:22,280
power no that is a pretty stained block yeah you can see I've got actually yeah

60
00:04:19,880 --> 00:04:27,960
that that takes off the top layer of it so let's just do this one

61
00:04:25,639 --> 00:04:32,800
bar bar wave I don't know whatever you want to call it

62
00:04:31,199 --> 00:04:40,160
there we go so you can see that the metal itself

63
00:04:36,639 --> 00:04:42,520
is uh is discolored

64
00:04:40,160 --> 00:04:48,280
there so there you go I will not be reusing this particular block um under

65
00:04:46,320 --> 00:04:53,680
any circumstances and uh yeah that's a

66
00:04:51,479 --> 00:04:57,680
that's a shame well thank you for checking out this

67
00:04:54,919 --> 00:05:02,440
little Discovery episode of my video blog don't forget to subscribe to L

68
00:05:00,360 --> 00:05:04,880
techtips for more unboxings reviews and other computer videos it looks like

69
00:05:03,680 --> 00:05:10,680
there's actually a few of these there's one here yeah there you go you can see

70
00:05:06,720 --> 00:05:13,080
that there's a couple places here here

71
00:05:10,680 --> 00:05:20,039
and here where it seems like there's very very small imperfections that then

72
00:05:15,199 --> 00:05:20,039
just from the water flow carried

73
00:05:20,680 --> 00:05:25,600
um carried away some metal particles

74
00:05:24,039 --> 00:05:31,479
that deposited themselves onto the nickel looks like up here was kind of

75
00:05:28,759 --> 00:05:31,479
bad

76
00:05:32,160 --> 00:05:36,680
and uh look there's a couple more marks

77
00:05:35,199 --> 00:05:40,639
in there if anyone knows more about Metal than I do feel free to chime in

78
00:05:39,039 --> 00:05:45,479
and suggest how this might have happened remember this is nickel plated

79
00:05:42,600 --> 00:05:49,639
copper and I think we're done here actually one more thing guys I

80
00:05:47,759 --> 00:05:53,880
should note that it's been quite a while since EK has had these problems with

81
00:05:51,600 --> 00:05:59,560
their blocks so this video was just more for um the sake of that I was working on

82
00:05:57,680 --> 00:06:03,600
it anyway so I figured I might as well shot a video about it it's not a warning

83
00:06:01,600 --> 00:06:06,840
about EK products they've uh they've tightened up the quality control on

84
00:06:05,240 --> 00:06:10,720
their nickel plating processes so any recent blocks should be fine however if

85
00:06:08,800 --> 00:06:13,759
you do have a 480 or a 470 block something from this generation of

86
00:06:11,960 --> 00:06:16,880
products might be worthwhile to have a look in your Loop and if your case is

87
00:06:15,319 --> 00:06:19,880
closed make sure that you don't have any gunk
