1
00:00:07,359 --> 00:00:14,719
slick and I want to do subjective readings of some fans at 7 volts versus

2
00:00:11,519 --> 00:00:16,760
at 12 volts in terms of how they sound

3
00:00:14,719 --> 00:00:24,160
and uh we discovered that we don't have a single 12 to 7vt resistor in the

4
00:00:21,039 --> 00:00:25,640
entire Tech tip studio so uh because the

5
00:00:24,160 --> 00:00:29,599
rest of the office is closed off right now I'm forced to make myself a ghetto

6
00:00:27,640 --> 00:00:32,520
one I mean this is one of those never ever do this but I'm going to show you

7
00:00:31,080 --> 00:00:38,600
how to do it anyway just in case you ever have to kind of things so basically

8
00:00:35,520 --> 00:00:40,239
you've got a standard four pin two three

9
00:00:38,600 --> 00:00:43,719
pin adapter oh is this even going to be able to plug into all the fans I guess

10
00:00:41,600 --> 00:00:48,800
we'll have to uh well all you got to do is just cut away the um the casing

11
00:00:45,680 --> 00:00:50,879
anyway standard four pin MOA hog U

12
00:00:48,800 --> 00:00:54,559
peripheral connector to three pin so the way that voltage is derived is from a

13
00:00:52,680 --> 00:01:00,840
difference so yellow carries 12 volt black carries ground so that will

14
00:00:56,199 --> 00:01:03,680
deliver 12 volts to the fan however

15
00:01:00,840 --> 00:01:07,759
if I take okay so a way to deliver 5 volts to the fan would be to hook the

16
00:01:05,360 --> 00:01:11,720
fan up to this and this or this and this so this is this carries 5 volts this

17
00:01:09,479 --> 00:01:16,759
carries 12 these carry ground however if I want to deliver seven volts to the fan

18
00:01:13,759 --> 00:01:20,040
I can hook the 12vt up to the 5 volt and

19
00:01:16,759 --> 00:01:21,360
that will be a difference of 7 volts so

20
00:01:20,040 --> 00:01:26,560
I'm going to show you guys how to do this never ever do this of course and

21
00:01:23,560 --> 00:01:29,000
most importantly once you plug this in

22
00:01:26,560 --> 00:01:32,720
never plug like a hard drive or anything into this because it'll will be miswired

23
00:01:30,759 --> 00:01:38,399
now because I've changed these around so all you got to do if you guys have uh

24
00:01:35,119 --> 00:01:39,799
have ever depinned a Molex before then

25
00:01:38,399 --> 00:01:43,840
you'll know how to do this but you just kind of grab it uh it's better to have

26
00:01:42,040 --> 00:01:47,040
better tools but I don't happen to have my tools with me because we're trying to

27
00:01:45,560 --> 00:01:52,920
do something here and we don't have a whole lot of time so um there we go oh

28
00:01:51,600 --> 00:01:58,119
apparently the battery is running out on the camera too so I'll just work on this while slick goes and changes the battery

29
00:01:56,000 --> 00:02:02,200
and then we'll be good to go so all you do is bend the pins in with a needle a

30
00:02:00,079 --> 00:02:05,439
little bit so you bend those two tabs on either side of the pin so I'm just going

31
00:02:03,479 --> 00:02:08,080
to do this one really quick here uh just need to see where they are yeah with the

32
00:02:06,920 --> 00:02:13,520
camera there it's pretty hard to see what I'm doing but it's okay it's all good there we go okay so you pull that

33
00:02:11,640 --> 00:02:18,440
out once you pull it out you then bend the tabs back out so that they'll hook

34
00:02:15,519 --> 00:02:22,519
back in once you uh once you put them back in see how they're flared now and

35
00:02:20,640 --> 00:02:28,760
then the one that I bent in is not flared anymore so you just go ahead and

36
00:02:25,560 --> 00:02:30,920
stick that in there and sort of try to

37
00:02:28,760 --> 00:02:37,560
my needle's really dull now because I've used it for this an awful lot there you

38
00:02:32,840 --> 00:02:39,280
go flare that out flare that out so yeah

39
00:02:37,560 --> 00:02:43,560
once again like if you ever make yourself an adapter like this I have one

40
00:02:40,959 --> 00:02:49,760
at home that I made like what I did was I wrapped it up like this and then I

41
00:02:45,640 --> 00:02:51,280
like wrote on here 7v fan adapter like

42
00:02:49,760 --> 00:02:54,840
do not plug and then if you're really smart you might like cover this with

43
00:02:52,840 --> 00:02:58,400
something so you never accidentally plug something in so basically I'm going to

44
00:02:56,560 --> 00:03:05,040
take this and throw it in there take this and throw it in there

45
00:03:00,640 --> 00:03:07,720
and now I have made myself see how I

46
00:03:05,040 --> 00:03:18,000
have this now going to what is essentially 12vt and 5V I made myself a

47
00:03:11,319 --> 00:03:18,000
7v fan adapter which you should never do
