00:00:00.080 --> 00:00:07.759
oh wow you idiot you bought a

00:00:03.840 --> 00:00:10.080
one of these for one of these and

00:00:07.759 --> 00:00:14.920
i bet you're enjoying your pc doubling as your room

00:00:14.920 --> 00:00:22.400
heater that's been a running joke for over 15 years now

00:00:20.320 --> 00:00:28.240
so we figured then why not purpose build a system that is

00:00:25.039 --> 00:00:31.119
specifically designed from the get-go to

00:00:28.240 --> 00:00:36.079
warm your room could this actually be practical and how would it compare to a

00:00:34.000 --> 00:00:41.360
purpose-built space heater stay tuned to find out

00:00:39.040 --> 00:00:45.840
after i tell you about our sponsor noble chairs their icon series real leather

00:00:44.079 --> 00:00:50.399
edition gaming chair was designed in germany and inspired by luxury sports

00:00:48.160 --> 00:00:53.399
car interiors learn more at the link below

00:01:00.239 --> 00:01:06.400
let's start with some college dropout level physics according to the first law

00:01:04.320 --> 00:01:10.720
of thermodynamics energy can either be created nor destroyed it can only be

00:01:08.159 --> 00:01:17.439
changed from one form into another which means that other than the small amount

00:01:14.640 --> 00:01:22.960
of kinetic energy to turn like your fans and the light energy to run

00:01:20.080 --> 00:01:28.960
your dope ass RGB all of the power being consumed by your gaming rig right now is

00:01:26.000 --> 00:01:33.439
being dumped into the room as waste heat making

00:01:29.920 --> 00:01:35.920
every pc basically a sophisticated space

00:01:33.439 --> 00:01:41.360
heater all right so this is our space heater pc it's got an AMD

00:01:38.479 --> 00:01:45.520
Threadripper processor it's got a gtx 1080 it's got a fanless power supply so

00:01:44.240 --> 00:01:49.759
you know we're not generating any more kinetic energy than

00:01:47.680 --> 00:01:54.399
we absolutely have to and the whole thing has been tuned to match the power

00:01:52.320 --> 00:01:59.600
consumption of this guy right here one of the key aspects of the

00:01:56.799 --> 00:02:04.719
design of the system was using ek's phoenix mlc water cooling kit so it's a

00:02:02.320 --> 00:02:09.280
modular liquid cooler that allows us to quickly connect or disconnect any

00:02:07.040 --> 00:02:12.720
components we want so we can either use an internal radiator for testing

00:02:11.039 --> 00:02:18.400
purposes or unplug the whole thing here

00:02:15.440 --> 00:02:20.840
to connect it to our external cooler this

00:02:19.440 --> 00:02:25.680
is bertha she's a little rough around the

00:02:24.239 --> 00:02:28.879
edges but with this plan

00:02:29.440 --> 00:02:37.200
we think we can use an old radiant heater which would traditionally be

00:02:34.560 --> 00:02:39.680
hooked up to a gas firing something to cool our pc

00:02:38.720 --> 00:02:44.800
and heat our room

00:02:42.560 --> 00:02:49.280
so first order of business whenever you find a radiator behind like a jamaican

00:02:47.920 --> 00:02:54.560
guy's house is cleaning

00:02:51.840 --> 00:03:00.000
now cleaning something like this is not as straightforward as you know

00:02:57.920 --> 00:03:03.560
throwing some water in it shaking it around

00:03:04.159 --> 00:03:11.760
calling it a day we filled the radiator up with water and vinegar let it sit for

00:03:08.480 --> 00:03:14.319
24 hours and drained it the contents

00:03:11.760 --> 00:03:14.319
were

00:03:17.360 --> 00:03:24.159
the worst after the initial flush we filled the radiator up with tap water and let it

00:03:22.080 --> 00:03:29.200
run upside down for a while messing up ivan's LTT adidas in the

00:03:26.640 --> 00:03:32.239
process oh no my shoes uh-oh

00:03:30.400 --> 00:03:36.560
after half an hour of running water at tap pressure through it it started to

00:03:34.239 --> 00:03:40.879
look clean now in order to mate the radiator's

00:03:38.480 --> 00:03:46.560
original piping to our water cooling hoses we needed to thread the stock pipe

00:03:43.840 --> 00:03:51.120
unfortunately the die bit so hard on reverse that the tube disconnected from

00:03:48.799 --> 00:03:54.879
the adjacent elbow and when we tried to vise the tube without the elbow it

00:03:53.440 --> 00:03:59.200
ovalized luckily we had compatible sections from

00:03:57.200 --> 00:04:03.120
another project sitting around so we teflon tape the threads and here's the

00:04:01.840 --> 00:04:09.120
result after rigging the radiator up with an industrial pump in a reservoir we were

00:04:06.799 --> 00:04:12.879
ready to fill it up ivan was so upset that i got his adidas wet that you can

00:04:10.879 --> 00:04:16.479
clearly see him trying to electrocute me here completely okay we have to turn off

00:04:14.640 --> 00:04:21.120
the water ivan there's so much water we're going to kill the pump

00:04:18.720 --> 00:04:25.360
the good news is that he failed better luck next time chump the bad news is

00:04:23.600 --> 00:04:29.759
that with the liquid pumping at an industrial pump pressure oh it's so

00:04:27.360 --> 00:04:35.759
dirty not only did it become brownish again but we also detected a minor leak

00:04:33.040 --> 00:04:40.160
it is a pretty substantial leak that like that will affect no that won't

00:04:38.000 --> 00:04:43.840
work you need teflon tape just tightening it more will not work after

00:04:42.160 --> 00:04:48.479
going gordon freeman on the joint with a crowbar we were able to disconnect it

00:04:45.840 --> 00:04:54.639
and teflon tape it adding a t-line drain in the process you know just in case

00:04:51.919 --> 00:04:59.600
good thing too it ended up taking four fills and flushes before the water

00:04:57.280 --> 00:05:03.440
stayed clear now as those of you who watched our full room water cooling

00:05:01.199 --> 00:05:07.919
project know mixing metals in a loop essentially creates a battery causing

00:05:05.600 --> 00:05:12.960
corrosion this can be mitigated by adding sacrificial anodes to the loop

00:05:10.479 --> 00:05:17.120
but due to our testing being very short term we omitted this step while we were

00:05:14.880 --> 00:05:22.160
doing all that we had our space heater running inside the room that we call the

00:05:19.199 --> 00:05:26.400
sanity closet so in here and we didn't want anybody opening this door because

00:05:24.160 --> 00:05:30.639
that would let the stank out so to speak so in here this is a five cubic meter

00:05:29.759 --> 00:05:35.600
room approximately accounting for the the

00:05:33.280 --> 00:05:42.000
boxes kind of taking up some of it we've got a wirelessly monitorable temperature

00:05:38.639 --> 00:05:44.479
sensor here and then we had our 350 watt

00:05:42.000 --> 00:05:49.919
heater running here so the sanity closet started at 23.7 degrees celsius which is

00:05:47.680 --> 00:05:56.880
our office temperature and then what we've done is we have configured our

00:05:52.479 --> 00:05:58.400
test to stop at 36.7 degrees which is

00:05:56.880 --> 00:06:02.080
the temperature of the human body you wouldn't really want your room any

00:06:00.160 --> 00:06:07.360
warmer than that would start to feel like a sauna so if our pc heats up this

00:06:05.440 --> 00:06:11.360
room from the same temperature to the same temperature in the same amount of

00:06:08.960 --> 00:06:16.160
time then we consider our experiment a success one last thing we needed some

00:06:14.160 --> 00:06:21.759
kind of opening at the back of the case to pipe the quick disconnect through

00:06:19.120 --> 00:06:25.759
finally we just needed to drag our beast into the closet hook her up to the

00:06:23.520 --> 00:06:33.160
radiator via the quick disconnects so all we've got to do is hook these babies

00:06:29.520 --> 00:06:33.160
up to these babies

00:06:34.880 --> 00:06:41.680
and uh let it bake for a bit

00:06:38.960 --> 00:06:46.560
finally time to check on this and see how we did with our pc

00:06:46.840 --> 00:06:52.479
so this is interesting our FPS

00:06:50.720 --> 00:06:58.960
are is lower and even though it's water cooled our

00:06:54.400 --> 00:07:01.960
GPU is over it's over 85 degrees

00:06:58.960 --> 00:07:01.960
oh

00:07:02.160 --> 00:07:09.280
our power consumption is only about 275

00:07:05.840 --> 00:07:12.560
280 watts

00:07:09.280 --> 00:07:15.560
our graphics card is thermal throttling

00:07:12.560 --> 00:07:15.560
okay

00:07:16.400 --> 00:07:23.919
let's have a look at what's going on in here whoa wow

00:07:21.360 --> 00:07:28.800
that is a heat wave and

00:07:24.960 --> 00:07:32.479
i think it's pretty clear what happened

00:07:28.800 --> 00:07:34.720
it looks like oh that's hot oh

00:07:32.479 --> 00:07:38.960
oh i think

00:07:36.720 --> 00:07:43.039
once our system heated up it made it easier

00:07:40.960 --> 00:07:49.840
for it to gather gunk that was still stuck on the inside of the radiator

00:07:46.639 --> 00:07:51.520
oh that's a real shame

00:07:49.840 --> 00:07:54.560
all right come on over here dennis come have a look oh

00:07:56.560 --> 00:07:59.560
so

00:08:00.560 --> 00:08:09.599
here's our gp yeah okay

00:08:04.560 --> 00:08:10.840
our GPU is totally gummed up

00:08:09.599 --> 00:08:17.919
what a shame so that affects the amount of heat

00:08:15.199 --> 00:08:23.360
that we were kicking out into the room actually we found a silver lining here

00:08:20.800 --> 00:08:28.720
so we didn't factor in that this high-powered pump

00:08:26.639 --> 00:08:33.440
consumes a lot of power it turns out that it's actually about 75

00:08:31.360 --> 00:08:36.719
watts so

00:08:35.200 --> 00:08:42.159
our numbers should still be okay

00:08:38.959 --> 00:08:45.360
okay so after importing all the data it

00:08:42.159 --> 00:08:48.000
wasn't immediately obvious

00:08:45.360 --> 00:08:52.720
how it all came together and made sense because upon initial inspection they

00:08:51.440 --> 00:08:58.240
actually look like really different results between

00:08:54.640 --> 00:09:00.800
the space heater and the pc but

00:08:58.240 --> 00:09:07.040
what we didn't factor in initially looking at it

00:09:02.720 --> 00:09:09.600
is the immense thermal mass of the water

00:09:07.040 --> 00:09:14.560
inside the radiator so what's actually happening here

00:09:11.040 --> 00:09:17.200
is that water is taking a long time to

00:09:14.560 --> 00:09:22.640
begin to heat up enough that the radiator itself is able to start

00:09:19.200 --> 00:09:23.440
dissipating heat to the surrounding air

00:09:22.640 --> 00:09:28.399
so in effect all we need to do is time

00:09:26.320 --> 00:09:34.240
shift our graph a little bit and what you can see is that even though the pc

00:09:31.680 --> 00:09:39.760
it lags about two degrees behind the space heater they both heat the room at

00:09:37.680 --> 00:09:42.800
the same rate so

00:09:41.120 --> 00:09:47.519
conclusion time can you use your pc

00:09:45.120 --> 00:09:53.279
as a heater for your room the answer is yes but we don't recommend

00:09:51.600 --> 00:09:59.920
the way we did it because if you do it the way we did it

00:09:56.480 --> 00:10:01.760
you're gonna lag behind by two degrees

00:09:59.920 --> 00:10:06.959
and all gamers know that any amount of lag is unacceptable

00:10:05.200 --> 00:10:11.200
which obviously is totally not the problem like this this this gunk in the

00:10:09.519 --> 00:10:16.560
in the water that's that's the problem speaking of problems

00:10:13.519 --> 00:10:18.560
if you don't already have a vpn

00:10:16.560 --> 00:10:22.800
that's a problem go check out private internet access they support a variety

00:10:20.480 --> 00:10:26.560
of vpn protocols and types of encryption and authentication which allows you to

00:10:24.640 --> 00:10:30.560
dial in the exact level of privacy protection that you need they've got

00:10:28.160 --> 00:10:34.959
apps for Windows macOS Android iOS Linux and google chrome with support for

00:10:32.800 --> 00:10:39.440
other platforms coming soon you can connect up to five devices at the same

00:10:36.880 --> 00:10:44.640
time and their apps include dns leak protection and ipv6 leak protection with

00:10:42.640 --> 00:10:48.959
an internet kill switch that will block all traffic if the vpn becomes

00:10:46.720 --> 00:10:52.320
disconnected unexpectedly so check it out today at the link in the video

00:10:50.399 --> 00:10:59.040
description and if you've already got pia hey they've got gift cards

00:10:55.839 --> 00:11:00.480
so we'll have that linked below as well

00:10:59.040 --> 00:11:04.160

join sometimes we just do stuff you know

00:11:22.800 --> 00:11:30.760
it's like yep we did a thing

00:11:26.839 --> 00:11:30.760
but why
