slick and I want to do subjective readings of some fans at 7 volts versus
at 12 volts in terms of how they sound
and uh we discovered that we don't have a single 12 to 7vt resistor in the
entire Tech tip studio so uh because the
rest of the office is closed off right now I'm forced to make myself a ghetto
one I mean this is one of those never ever do this but I'm going to show you
how to do it anyway just in case you ever have to kind of things so basically
you've got a standard four pin two three
pin adapter oh is this even going to be able to plug into all the fans I guess
we'll have to uh well all you got to do is just cut away the um the casing
anyway standard four pin MOA hog U
peripheral connector to three pin so the way that voltage is derived is from a
difference so yellow carries 12 volt black carries ground so that will
deliver 12 volts to the fan however
if I take okay so a way to deliver 5 volts to the fan would be to hook the
fan up to this and this or this and this so this is this carries 5 volts this
carries 12 these carry ground however if I want to deliver seven volts to the fan
I can hook the 12vt up to the 5 volt and
that will be a difference of 7 volts so
I'm going to show you guys how to do this never ever do this of course and
most importantly once you plug this in
never plug like a hard drive or anything into this because it'll will be miswired
now because I've changed these around so all you got to do if you guys have uh
have ever depinned a Molex before then
you'll know how to do this but you just kind of grab it uh it's better to have
better tools but I don't happen to have my tools with me because we're trying to
do something here and we don't have a whole lot of time so um there we go oh
apparently the battery is running out on the camera too so I'll just work on this while slick goes and changes the battery
and then we'll be good to go so all you do is bend the pins in with a needle a
little bit so you bend those two tabs on either side of the pin so I'm just going
to do this one really quick here uh just need to see where they are yeah with the
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
out once you pull it out you then bend the tabs back out so that they'll hook
back in once you uh once you put them back in see how they're flared now and
then the one that I bent in is not flared anymore so you just go ahead and
stick that in there and sort of try to
my needle's really dull now because I've used it for this an awful lot there you
go flare that out flare that out so yeah
once again like if you ever make yourself an adapter like this I have one
at home that I made like what I did was I wrapped it up like this and then I
like wrote on here 7v fan adapter like
do not plug and then if you're really smart you might like cover this with
something so you never accidentally plug something in so basically I'm going to
take this and throw it in there take this and throw it in there
and now I have made myself see how I
have this now going to what is essentially 12vt and 5V I made myself a
7v fan adapter which you should never do
