00:00:07,359 --> 00:00:13,280
welcome to a crazy you know rig

2
00:00:10,960 --> 00:00:17,199
sort of feature showcase honestly this was one of the things about slick's

3
00:00:14,880 --> 00:00:21,520
resume that really popped out at me because he actually put this on his

4
00:00:19,600 --> 00:00:26,080
resume he was like i have a computer that's like oil cooled and i was like

5
00:00:24,640 --> 00:00:29,359
okay i guess and uh so i had to talk to this guy of

6
00:00:28,000 --> 00:00:35,200
course right because who puts that on a resume i was like i really hope this is a custom resume i hope you don't like

7
00:00:32,960 --> 00:00:38,640
apply for a job at like a car dealership and you're like yeah i have an oil

8
00:00:36,239 --> 00:00:44,480
cooled computer because they'd be like okay oil is like for cars

9
00:00:41,920 --> 00:00:47,840
and stuff no we're not talking motor oil we're talking mineral oil so this is

10
00:00:46,480 --> 00:00:52,719
slick's oil cooled machine which is actually

11
00:00:50,559 --> 00:00:59,680
still running after all this time so this is back when a 70di a qx6700

12
00:00:57,280 --> 00:01:04,879
eight gigs of Corsair dominator what the heck is this stuff

13
00:01:01,280 --> 00:01:07,040
uh 8500 memory so this is somehow he

14
00:01:04,879 --> 00:01:11,760
managed on a 780i board to get four dimms working by some freaking miracle

15
00:01:09,520 --> 00:01:15,600
is the thing overclocked too a little bit yeah a little bit exactly

16
00:01:13,520 --> 00:01:21,840
because that's not an easy feat i can tell you guys that much GeForce gtx 260.

17
00:01:18,880 --> 00:01:25,119
you see you can see the uh the ddc or ddc plus i don't know what it is it's

18
00:01:23,280 --> 00:01:28,560
some kind of pump going on in there you can also see he's got like seriously

19
00:01:26,960 --> 00:01:33,360
this thing is old school but legit hardware check this out hx 620 modular

20
00:01:31,680 --> 00:01:37,920
power supply with all of the casing stripped off so even the fan is gone

21
00:01:35,840 --> 00:01:42,159
however you can see from the tubing coming in here that he's got the fresh

22
00:01:40,240 --> 00:01:45,759
coolant coming in near the power supply so i think he recognizes that the power

23
00:01:43,840 --> 00:01:49,600
supply would be one of the more disastrous things to go wrong in a

24
00:01:47,520 --> 00:01:53,040
mineral oil cooled computer so one of the questions that a lot of people have

25
00:01:51,360 --> 00:01:56,560
about oil cooling is

26
00:01:54,399 --> 00:02:01,520
why does this work and not water because you always hear people say well

27
00:01:58,399 --> 00:02:04,000
deionized water is non-conductive and it

28
00:02:01,520 --> 00:02:09,440
is but the difference is that deionized water is also very aggressive in picking

29
00:02:07,360 --> 00:02:14,480
up ions from metal that is placed in it so whether it's an aluminum heat sink or

30
00:02:12,160 --> 00:02:19,120
whether it's a copper you know exposed portion of a pcb or

31
00:02:17,120 --> 00:02:23,040
whatever else the case may be that distilled or deionized water is going to

32
00:02:21,360 --> 00:02:27,599
pick up ions like that and it will probably short out within about 10 or 15

33
00:02:25,040 --> 00:02:31,680
minutes whereas mineral oil is much more inert and is much easier to have running

34
00:02:30,000 --> 00:02:36,000
on a long-term basis so this has been running pretty much non-stop other than

35
00:02:34,400 --> 00:02:39,920
an incident where there was some kind of a party at the dorm that he was staying

36
00:02:37,760 --> 00:02:43,040
in and someone broke the bottom of it or something along those lines had to be

37
00:02:41,360 --> 00:02:46,800
refilled other than that it's been running pretty much non-stop all this

38
00:02:44,560 --> 00:02:50,720
time now if he had a bigger reservoir he could probably run it without an

39
00:02:48,160 --> 00:02:54,239
external radiator but due to the fact that he's using a fairly compact case if

40
00:02:52,879 --> 00:02:59,280
you guys come here and look at it from the top you can see it's only about an

41
00:02:56,080 --> 00:03:00,959
atx mini tower size case it's actually

42
00:02:59,280 --> 00:03:04,720
probably even smaller than that this is more like an m atx case because the

43
00:03:02,720 --> 00:03:09,120
power supply instead of being mounted here or on the bottom is actually just

44
00:03:07,040 --> 00:03:13,519
like ghetto mounted near the memory most cases are not designed this way so what

45
00:03:11,280 --> 00:03:19,120
he's done is he's used a quadruple so that's a four by one 20 millimeter

46
00:03:16,480 --> 00:03:22,800
ghetto sauce radiator although it is a thick radiator so in terms of

47
00:03:20,480 --> 00:03:26,480
performance it's going to be darn close to something like a thermo chill

48
00:03:24,159 --> 00:03:29,599
quadruple radiator he's got 3 8 inch tubing which by the way is very stiff

49
00:03:28,080 --> 00:03:33,599
the mineral oil has some interesting effects on your hardware including

50
00:03:31,680 --> 00:03:37,360
stiffening up cables that it can it creeps its way up so it'll stiffen

51
00:03:35,200 --> 00:03:42,000
cables stiffen tubing and it can be a bit of a challenge that way now

52
00:03:40,400 --> 00:03:45,680
if only solid-state drives had been feasible at

53
00:03:44,400 --> 00:03:50,319
the time that he built this machine you probably wouldn't have to have a mechanical drive here but you can

54
00:03:48,239 --> 00:03:54,879
actually see there's a mechanical hard drive right there hiding under yep

55
00:03:52,640 --> 00:03:57,760
hiding under this lip because mechanical hard drives are one of the few

56
00:03:56,080 --> 00:04:03,200
components along with optical drives you can see he uses an external optical

57
00:03:59,280 --> 00:04:03,200
drive do not sell are you kidding me

58
00:04:04,239 --> 00:04:11,519
are one of the few components they cannot run in mineral oil due to the

59
00:04:08,879 --> 00:04:15,439
fact that they would just die instantly so uh

60
00:04:12,640 --> 00:04:19,359
so yeah you know the oil inside the hard drive would be really bad for the 7200

61
00:04:17,600 --> 00:04:24,720
RPM spinning platters they would slow down a lot um which is bad so anyway so

62
00:04:22,639 --> 00:04:28,720
he went with a hard drive an SSD however could run inside here just fine now

63
00:04:26,960 --> 00:04:33,600
speaking of things slowing down in the mineral value you can see that it is

64
00:04:30,639 --> 00:04:37,040
still sort of fan cooled in spite of the fact that there is there's mineral oil

65
00:04:35,680 --> 00:04:40,960
going on inside here these fans have slowed down however due to the

66
00:04:39,440 --> 00:04:44,639
properties of the mineral oil they actually are not damaged by this i mean

67
00:04:42,720 --> 00:04:48,560
they're running in lubricant so it's not the end of the world to have them to

68
00:04:46,639 --> 00:04:51,759
have them running submerged like this i'm just trying to see if i've missed

69
00:04:49,759 --> 00:04:56,000
anything the decorative plant is fantastic of course

70
00:04:53,600 --> 00:05:00,479
and so is his he actually doesn't own a single cougar thing as far as i can tell

71
00:04:58,400 --> 00:05:03,840
i mean maybe maybe the girl he's dating you know gave him this

72
00:05:02,560 --> 00:05:11,520
um what else does he have that's not like ghetto i mean that's a cool machine

73
00:05:08,080 --> 00:05:12,880
like a few years ago but uh okay yeah he

74
00:05:11,520 --> 00:05:16,800
he loves this keyboard this is a mechanical keyboard

75
00:05:14,560 --> 00:05:21,120
um it's a ducky he put like you know custom keycaps on it

76
00:05:19,680 --> 00:05:25,600
he's kind of a geek you know that's that's sort of par for

77
00:05:24,000 --> 00:05:31,039
the course when it comes to working in this business i think that's pretty much it as far as

78
00:05:29,199 --> 00:05:34,560
slicks liquid cooled mission liquid you'll see i kept

79
00:05:32,560 --> 00:05:38,960
going into habits here oil cooled machines so i hope you guys enjoyed me

80
00:05:36,800 --> 00:05:42,479
sharing this with you and don't forget to subscribe to Linus tech tips for more

81
00:05:40,400 --> 00:05:46,800
unboxings reviews and other computer videos although i cannot promise that

82
00:05:44,320 --> 00:05:50,800
i'll be doing ones like this very often and uh for those of you who are

83
00:05:48,160 --> 00:05:53,520
inevitably gonna post do an oil-cooled machine build guide

84
00:05:52,560 --> 00:06:00,560
no not going to happen it's way too much work and the hardware is pretty much

85
00:05:57,919 --> 00:06:04,880
fubar by the end of it because he said to dry something to drip dry one

86
00:06:03,039 --> 00:06:08,319
of these components out is going to take a matter of weeks

87
00:06:06,479 --> 00:06:12,560
we're not talking days we're not talking like you know dusted off we're talking like

88
00:06:10,960 --> 00:06:16,479
by the time you can actually use this in an air-cooled environment and not have

89
00:06:14,720 --> 00:06:21,360
it just be disgusting and get oil all over everything we're talking weak so

90
00:06:18,319 --> 00:06:22,960
anyway cool machine flick um

91
00:06:21,360 --> 00:06:26,160
you know i don't think when he upgrades this to something modern he's probably

92
00:06:24,479 --> 00:06:29,600
going to stick with the oil config he says no but it was fun while it lasted

93
00:06:28,240 --> 00:06:34,039
and it was definitely an interesting item on the resume don't forget to subscribe
