so we're back on the site of personal rig update 2015 now some of you pointed
out that putting all this computer equipment into a closet could lead to
overheating issues and while this room
actually is technically an exterior room this is an insulated wall right here and
through this Gap is direct access to the outside and through that Gap is direct
access to the attic it's only passively ventilated and in practice we've gone
from being pretty close to outdoor temperature to it being about 13° C
putting this equipment in initially to it being about 18° C on a warm day here
in April so from past experience I'm expecting it to go as high as 35 to 40°
C In the Heat of the midsummer obviously
that's not acceptable so we're going to have to put a contingency plan into
action welcome to personal rig update 2015 part whatever the crap this is and
yes I know it's not 2015 anymore ventilating the
room the Arya headphones from Phoenix come complete with a cardioid clip mic
and acoustic Chambers constructed entirely of Japanese Pinewood check out
the link in the video description to learn more now as a number of you have noted
on at least several occasions I'm not particularly handy and when it comes to
knock walking out walls and installing
ventilation fans I am not going to be anyone's First Choice as a general
contractor so I have brought in my crack
team Mark and Praxis who are going to be
well helping me with basically doing it for me but before they can do that
there's some stuff I need to do because I've already started using this room as
storage again and I've been informed that all this yes even this that I
worked so hard to put in here has to come out I guess we'll start by
shutting everything down I'm going to have no internet today or
tomorrow how will I live it's like a fish with no internet or water well here
we go I'm just going to have to haul this out of
here my ceiling mounted access
point there we go such winers o we don't
have power o we're running on battery I
don't actually have power in this room so this is a power car that runs through
the wall to uh an outlet and then everything else here is also just kind
of running through that same hole which is just a hole I made in the drywall is
there perhaps while we're redoing these walls is there perhaps a more elegant
way to achieve this well I could actually put outlets on this wall
something I should have done 6 years ago basically yeah yeah yeah okay suggestion
for your lighting LED pot light oh neat
low voltage wow those are really small so the Transformer it only uses 12 WS Al
I'm not going to have like the the incandescent page thing hanging off the
yeah yeah that's it just what you don't like this not really oh well I think I
actually did even put this in myself now that I think about it yeah it was broken
in this room I put this in did I do okay no
oh so I mean this is bizarre I I told
Mark I still had some more of this like
uh particle board with like a primed side stuff and he and I was like yeah
you can you can totally have that we you can put more of it in there he's like
you um so we are going to be ripping all of that out as opposed to just doing the
parts we need to access and drywalling it you can see it's really sturdily
constructed I mean it's not like he's taking it apart with his hands that's
totally not a thing that's happening let's see if I can pull it off with my hands never oh wow yeah that is not very
good I feel like He-Man just ripping walls apart fun fact never actually seen
an episode of He-Man I don't even know if He-Man is the name of the show He-Man
might just be like a guy on some other show you know what amazing I told Mark I
was going to be here to help today he still brought a helper I can't figure out why inexplicable I took an
electrical course in high
school thank you so uh I'm equipped with
my manly purple mask and my light I'm
going to go find out where those damn Cat 5 cables go to I think it's possible
that they actually go to the uh to the
garage like I think the house was kind
of wired for Ethernet but like not properly so if they go around the front
and across that way then that will be what they were for but it doesn't
actually look like they do one of them goes this way where are you going and
why are you going there e cobwebs ass
sper what the hell I figured out what it is okay they're using it as speaker wire
this is for the um it's for the ceiling
mounted speakers in the living room I don't understand why they're using C 5
for that maybe there's some reason but that explains it okay so that means that
this how the heck did they manage to do a drop unless
oh this goes straight down into that
wall oh that's cool that means if I wanted to run anything else in that wall
than I could and that is also how
they're getting coax in there I think
okay now I get it so now that we've got
everything torn out we've got a clear look at what we're working with and I
can outline exactly what the plan is we're going to pull off of this light
switch box right here and we're going to put an outlet in this room rather than
having me run a power bar through the wall because I'm sure that the fire department would freak out if they saw
that next we're going to install this low voltage uh LED lighting Dad we have
an inline 190 CFM fan which we'll use to
pump air into the room we need to control that with a cooling thermostat
and this is a low voltage connection and this is 120 volt so we need to use a
relay to have this tell the relay what to do in order to tell the fan what to
do okay so basically we're going to climb down into the sopit area down
there where conveniently there are already some ventilation duct things
that are for keeping this uh this insulation up here ventilated and we're
going to put like a service panel in here and just have it create a positive
air pressure situation in this room and then for ventilation out of the room
what we're thinking is we're just going to leave like maybe 6 to 8 in of free
space here in the drywall on the ceiling so that it can just passively exhaust
into the attic just like that so uh we
have a plan it's exactly the plan I would have come up with on my own
too so they're making me vacuum the rodent
poop guess I get that sort of my rodent
poop not theirs so the first step which you can
see practice working on here is using a combination of the included mounting
hardware and a little bit of Fabrication in the sofits to create a mounting point
for the intake fan that's going to cool the room the fan itself uh is free
flowed with with air um so we need to put a damper in so that when you don't
want air flowing in there say in the winter when it's cold you want this
to stop the air flow cool now the last step to make all
of this even have a point at all is to
insulate the ceiling because that is where the heat is coming from from the
Sun hitting the shake roof and basically conducting heat directly into this room
now fortunately this is relatively straightforward because we've already
got strapping right here so we're still going to have enough air flow through
here to keep the wood from rotting but we are going to have to fill it with
insulation and cover it with drywall in
order to make this room effectively part of the house rather than part of the
outside so phase one of the electrical work is actually pretty much done so
we've borrowed 120 volt power from the old incandescent pulley chain light that
used to be up here and we have brought it into this box right here so this is
where the light switch for our new LED light is actually going to go this guy
is going to contain this relay right here as well as this Transformer which
is going to take the 120 volt in and turn it into 24v power that our cooling
thermostat can handle without frying itself whenever the fan engages so
basically what should happen is when the temperature reaches a certain threshold
when it gets too warm it'll connect the circuit and in theory that'll turn on
the fan which as you guys can probably hear is
working just dandy
exciting so for the next stage in the project we're working on putting that
electrical Jack in as well as a better pass through into the room over here the
other update here is that the ducting is now installed so it's pretty
straightforward stuff we've just got some little metal accordion style
ducting here and then some foil tape affixing one duct to the fan on this
side so that that's where the exhaust is going to come into the room and then on
the other end we've got another piece of duct that's going right down to the sfet
where we're going to have to cut a ho for it outside now the clever among you
have probably realized at this point that that is just going to draw air not
only from the outside but also from the rest of the attic where we haven't
insulated and it's going to be quite hot no not so because we're going to jam
some insulation around the edges of it so that it can only draw air from the
outside okay so with the p over most of
the insulation in the walls now and the
drywall mostly well sort of maybe about half up we're ready to do an update
because once this wall is drywalled in this LED light is going to be
permanently mounted so it locks into the
connector a little something like that then we are going to simulate the
switch by joining these wires and there you
go it's an LED light and Brandon's going to have to adjust his exposure oh he's
is going to have to do it again oh he's going to have to do it one more time oh no oh no l is is live with the
light so that's going to go on the
wall so this is a quick status update more than anything else I realized that
the fan is a little on the loud side it's actually audible even through the
wall so what we're going to add is just a simple dimmer switch and we're just
going to tape it up box it inside here and close it away because it's not the
kind of thing that you would adjust very often and the other things that we can
have a look at that have changed since last time is that the fan has been
completely insulated around now so we are getting nice cool air like that is
Frosty air from outside and finally this
puppy has been reframed for a nice big access panel if in the future I want to
run oh I don't know more you know foone lines or coax lines or even power from
my garage or to anywhere else in the house because from here I can access the
entire upstairs and over to the garage now I don't have to
crawl through like I did the other day see much easier so we are pretty much at
the end the room is drywalled and mudded
the access hatch has been mostly created it just needs a bit of a handle on the
outside and check this out this dimmer
switch has been wired in it's kind of a getaway of doing it I know in a perfect
world you know the uh RPM of the fan
would be modulated by temperature as opposed to just by manually doing this
but this is functional since it's the kind of thing that I'm only going to have to set probably once a season
anyway so here's how it works we've got the fan on auto the system is set to
cool and if we turn the threshold down
the cooling fan kicks in but if I kind of go oh gee that's
really loud all I've got to do is before I close up this little access panel turn
that dimmer switch down and we can find the perfect balance between acoustic and
temperatures so finally the last step before benchmarking we've got to put a
grill on the outside air intake which is under the S here preferably one that is
B proof you know so that I don't have bees in my attic thank you for thinking
of that um and then we can Benchmark it
and find out just how well the system works yay
Wheels okay down
so all that's left now is the final
Benchmark so in order to evaluate whether this was a success or failure
because I don't want to just wait around for the summer and for the computers to
all overheat to find out is to look at
what the CPU temperature is under a heavy load relative to the outside
temperature when we're running intensive applications so I'm going to run heaven
in a window as opposed to full screen oops as well as Ida 64 CPU Benchmark in
order to evaluate what it will be like in a worst case scenario with the door
closed with our new cooling system off
and then with the new cooling system engaged and so here you have it guys
this is the result operation cool this
room appears for now to have been a success bringing in cool air from the
outside is going to help a lot to keep this room cool and at the rate that that
fan moves air we are circulating all of
the air in this room like every minute
or so not really giving the systems any time to heat up more than they normally
would well that was fun watching me get burned by the contractor among other
things but you don't have to get burned if you switch over to Ting the mobile
carrier that is focused on customer service and satisfaction first when you
call them this is crazy I actually tried it because I didn't actually quite
believe it when you call them you do not speak to a robot you get put through
directly to a person they answer the phone they're like hello this is Tang
what and the way that their billing works is different from other carriers
you don't have to commit to like 200 talk minutes during Prime hours and blah
blah blah megabytes you pay for only what you use and the average Ting bill
is only $24 per month per device if
you're stuck in a contract and you switch to Ting they'll cover 25% of your
cancellation Fe up to $75 and if you head over to l.com which is linked in
the video description when you sign up at our link you'll get 25 bucks in
service credit or towards a new device and the savings calculator is worth your
time all you do is enter your last few bills from your existing carrier and
Ting crunches some numbers and tells you whether you would save money by
switching to tting so check it out at the link in the video
