WEBVTT

00:00:07.359 --> 00:00:14.719
slick and I want to do subjective readings of some fans at 7 volts versus

00:00:11.519 --> 00:00:16.760
at 12 volts in terms of how they sound

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

00:00:21.039 --> 00:00:25.640
entire Tech tip studio so uh because the

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

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

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

00:00:35.520 --> 00:00:40.239
you've got a standard four pin two three

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

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

00:00:45.680 --> 00:00:50.879
anyway standard four pin MOA hog U

00:00:48.800 --> 00:00:54.559
peripheral connector to three pin so the way that voltage is derived is from a

00:00:52.680 --> 00:01:00.840
difference so yellow carries 12 volt black carries ground so that will

00:00:56.199 --> 00:01:03.680
deliver 12 volts to the fan however

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

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

00:01:09.479 --> 00:01:16.759
carries 12 these carry ground however if I want to deliver seven volts to the fan

00:01:13.759 --> 00:01:20.040
I can hook the 12vt up to the 5 volt and

00:01:16.759 --> 00:01:21.360
that will be a difference of 7 volts so

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

00:01:23.560 --> 00:01:29.000
most importantly once you plug this in

00:01:26.560 --> 00:01:32.720
never plug like a hard drive or anything into this because it'll will be miswired

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

00:01:35.119 --> 00:01:39.799
have ever depinned a Molex before then

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

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

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

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

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

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

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

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

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

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

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

00:02:25.560 --> 00:02:30.920
stick that in there and sort of try to

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

00:02:32.840 --> 00:02:39.280
go flare that out flare that out so yeah

00:02:37.560 --> 00:02:43.560
once again like if you ever make yourself an adapter like this I have one

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

00:02:45.640 --> 00:02:51.280
like wrote on here 7v fan adapter like

00:02:49.760 --> 00:02:54.840
do not plug and then if you're really smart you might like cover this with

00:02:52.840 --> 00:02:58.400
something so you never accidentally plug something in so basically I'm going to

00:02:56.560 --> 00:03:05.040
take this and throw it in there take this and throw it in there

00:03:00.640 --> 00:03:07.720
and now I have made myself see how I

00:03:05.040 --> 00:03:18.000
have this now going to what is essentially 12vt and 5V I made myself a

00:03:11.319 --> 00:03:18.000
7v fan adapter which you should never do
