00:00:00.000 --> 00:00:06.720
Here at Linus Tech Tips, we know that water cooling needs the cleanest water.

00:00:04.880 --> 00:00:10.480
We even installed a reverse osmosis filter in our shop to ensure that we'd

00:00:08.400 --> 00:00:14.559
have it. So, when we learned that there are more than 4 billion people around

00:00:12.639 --> 00:00:17.920
the world without access to safely managed drinking water at home, we

00:00:16.320 --> 00:00:22.480
realized we needed to be part of something bigger. That is why we're

00:00:20.080 --> 00:00:28.320
joining forces with Team Water to help them blow past their goal of raising $40

00:00:25.119 --> 00:00:30.560
million in just 30 days to provide clean

00:00:28.320 --> 00:00:36.640
drinking water to millions of people for decades to come. Which got us thinking,

00:00:33.760 --> 00:00:41.120
how dirty is unfiltered water? Do we even really need clean water for cooling

00:00:38.879 --> 00:00:45.280
computers? I asked our team to design a bit of a science fair project to find

00:00:42.960 --> 00:00:51.680
out if water cleanliness really matters when cooling your PC. And right under

00:00:48.079 --> 00:00:53.280
here are the satisfying results,

00:00:51.680 --> 00:00:57.039
which is exactly what business owners can expect when they use our sponsor,

00:00:54.879 --> 00:01:01.840
ODO's all-in-one suite of business apps for accounting, sales, inventory, and

00:00:59.199 --> 00:01:05.920
more. It's like having one guy with four arms. How's it going?

00:01:03.760 --> 00:01:09.400
>> I'm ODO. >> Yeah. So,

00:01:15.600 --> 00:01:22.960
I haven't seen this yet, so this is a big moment,

00:01:20.560 --> 00:01:27.840
huh? at first glance. Anyway, I got to be honest with you guys, I can't really

00:01:24.640 --> 00:01:30.320
tell the difference, which is pretty

00:01:27.840 --> 00:01:35.119
surprising given that this one here was filtered through a LifeStraw, which is

00:01:32.320 --> 00:01:40.560
supposed to knock out like 99.99 something% of the junk water. And this

00:01:37.840 --> 00:01:45.280
one came straight from this bucket of pond water. I um I'm not 100% sure what

00:01:43.280 --> 00:01:50.399
I expected to see, but with warm temperatures from the heat of the

00:01:47.119 --> 00:01:52.880
components plus sunlight, I don't know,

00:01:50.399 --> 00:01:57.680
tadpole algae, something. Did you guys do it right?

00:01:55.360 --> 00:02:00.320
>> Pretty sure we sent David and Justin to the pond and they got some water that

00:01:59.200 --> 00:02:04.960
looked terrible. There were ducks swimming all over the place.

00:02:03.759 --> 00:02:09.320
Then we were working on putting these two pretty much identical systems together.

00:02:11.520 --> 00:02:17.599
got interrupted by the ice cream van. I got a mango bar. I >> I didn't ask.

00:02:15.680 --> 00:02:21.440
>> Fair enough. Anyway, we're kind of as surprised as you at the result here. We

00:02:19.440 --> 00:02:24.239
even, you know, used transparent tubes. Everything we could have done has been

00:02:23.440 --> 00:02:27.599
done. >> And yet, life didn't find a way.

00:02:26.800 --> 00:02:34.080
Apparently not. >> No. Wait, hold on. >> No. I was looking at it with the wrong

00:02:31.680 --> 00:02:37.519
color in the background. If we get it just right, it has a tint to it.

00:02:36.480 --> 00:02:41.680
>> A little bit of yellow. >> Yeah. Yeah. >> Grab that paper. >> Yeah. Okay. Hold on. Wait. This is

00:02:40.239 --> 00:02:46.239
sitting right here. You knew. >> Maybe. >> Oh, that makes sense. Okay. So, uh here.

00:02:45.120 --> 00:02:51.760
Here. Do you want to hold the one? >> Yeah. >> This one crystal clear. This one crystal

00:02:50.080 --> 00:02:58.560
with some inclusions. >> Yellow crystal. >> It is. I've never been this excited to

00:02:54.720 --> 00:03:00.080
find dirty water. The question is, how

00:02:58.560 --> 00:03:04.159
dirty is it? >> Well, to find out, we got these petri

00:03:02.000 --> 00:03:07.200
dishes and did a swab test. That's the life. >> Oh my god.

00:03:05.599 --> 00:03:11.280
>> That's the pond water. That's disgusting. >> It really stinks.

00:03:09.360 --> 00:03:16.879
>> I mean, yeah, >> I might have the plague. Now,

00:03:15.040 --> 00:03:20.319
>> one quick note, by the way, the tests that you're watching were performed by

00:03:18.400 --> 00:03:24.720
professional idiots and should not be replicated at home. Growing bacteria,

00:03:22.879 --> 00:03:28.400
especially if you don't know what it is, for any reason, can be extremely

00:03:26.560 --> 00:03:33.680
dangerous to the health of you, your family, and your pets. Stay safe. These

00:03:31.280 --> 00:03:37.760
have been sitting in a very makeshift incubator that we built in the writer's

00:03:35.280 --> 00:03:43.200
room for the last few days. So, as it turns out, looks relatively clean and

00:03:40.000 --> 00:03:45.280
drinkable is still full of microbes and

00:03:43.200 --> 00:03:50.239
potentially harmful contaminants that if left unchecked in an environment like

00:03:47.200 --> 00:03:53.360
say your body or even this water cooling

00:03:50.239 --> 00:03:55.760
loop for long enough will grow and can

00:03:53.360 --> 00:03:59.439
cause serious health issues for both people and for gaming rigs.

00:03:57.840 --> 00:04:03.599
>> I've got more tests to run, too. >> Oh, sick. But before we do those, we

00:04:02.000 --> 00:04:08.239
should talk about Team Water. Working with the nonprofit Water Aid, who's been

00:04:05.760 --> 00:04:12.400
around for as long as Jordan and have a platinum seal of transparency from

00:04:09.920 --> 00:04:17.759
Guidear, Team Water is aiming to raise $40 million in just 31 days. So, they're

00:04:16.239 --> 00:04:23.919
going to need all the help they can get to raise more than $1 million a day. Go

00:04:21.120 --> 00:04:26.000
to teamwater.org to donate or to get more information. All right, where were

00:04:25.600 --> 00:04:30.400
we? >> You're going to want those. >> Oh, okay. Hey, I thought you were going

00:04:28.639 --> 00:04:34.479
somewhere entirely different with this. >> Not on camera.

00:04:32.560 --> 00:04:37.680
>> Speaking of, these are tests for fecal caulifform bacteria.

00:04:36.080 --> 00:04:43.199
>> Well, first, why don't we show them the water test that we got? >> Fair enough. We got this wellwater test

00:04:41.040 --> 00:04:47.199
kit from Canadian Tire. Dead simple. We just dip these test strips into our

00:04:45.040 --> 00:04:49.199
reservoirs. It'll change color depending on what's in the water. We match it up

00:04:48.639 --> 00:04:57.440
to the colors. >> Oh, cool. Okay. So, should I give it a shot? >> Give it a go.

00:04:51.840 --> 00:04:59.520
>> Okay. This is LifeStraw. 1,00 2 1 and

00:04:57.440 --> 00:05:04.639
total hardness a little hard. Got some hard water. No chlorine. That's good. No

00:05:02.240 --> 00:05:09.840
iron, I guess. Copper content, acceptable. Nitrate, none. Nitrite,

00:05:07.360 --> 00:05:12.560
none. Nice. We're a little bit on the harder side, which is something that you

00:05:11.120 --> 00:05:16.960
can be concerned about when you're taking water from a well. But everything

00:05:14.560 --> 00:05:21.759
else seems to be well within the safe range. You know, there's no chlorine in

00:05:19.600 --> 00:05:28.479
our water supply, for instance. Okay, I'm going to fold it this way this time.

00:05:24.560 --> 00:05:31.520
And one, two, boop. Total hardness,

00:05:28.479 --> 00:05:34.240
reasonable. Chlorine, iron, fine.

00:05:31.520 --> 00:05:42.320
Copper, fine. Nitrates and nitrites are fine. Fine, fine, fine, fine, and fine.

00:05:39.440 --> 00:05:47.039
And as expected, bacterial growth is not going to affect any of these elements.

00:05:44.560 --> 00:05:52.479
So if we were to sterilize this water, it should probably be pretty safe for

00:05:49.280 --> 00:05:53.840
drinking. And the sterilization is key.

00:05:52.479 --> 00:05:57.440
>> They thought of that. The kit also included this test for bacteria. And we

00:05:55.919 --> 00:06:00.400
bought a second one so we could do both systems. These will test for fecal

00:05:59.280 --> 00:06:06.560
cullififor bacteria. >> That sounds like a bad bacteria. >> You don't want to have it. Basically, if

00:06:03.600 --> 00:06:07.680
they turn green or bluish tint, that's positive test.

00:06:07.360 --> 00:06:12.160
>> Okay. >> So, here you go. >> So, you're telling me, wait a second. You're telling me this is the healthy

00:06:11.840 --> 00:06:17.600
one? >> That's the good one. >> I mean, I guess it doesn't really look

00:06:15.680 --> 00:06:21.919
like it came from a water that I would want to drink. It looks like uh we might

00:06:19.600 --> 00:06:26.720
have got it from uh >> Lar Reese.

00:06:23.919 --> 00:06:30.160
>> I mean, is this how I find out that we're doing employee drug testing?

00:06:28.560 --> 00:06:35.520
>> They don't tell you everything anymore. >> Anywh who, uh we took these samples

00:06:32.720 --> 00:06:40.880
about 30 hours ago. And while this one might look like the more appetizing one,

00:06:38.560 --> 00:06:42.880
that's bad. That's poop. >> That's poop.

00:06:41.600 --> 00:06:46.560
>> Poop bacteria. >> Yeah. Don't drink that. I mean, I wouldn't drink that either personally,

00:06:45.680 --> 00:06:53.720
but >> that's fair. Of course, we haven't proven that duck will affect gaming

00:06:50.240 --> 00:06:53.720
performance yet.

00:06:53.919 --> 00:07:02.000
Of course, none of this proves that duck will impact our FPS. So, to follow

00:07:00.240 --> 00:07:07.280
through with our experiment, we are going to now game on our two systems to

00:07:04.960 --> 00:07:11.759
see if they perform the same. All right, Jordan. Truthfully, I'm not expecting a

00:07:10.080 --> 00:07:15.280
difference in the actual performance of these machines. If we were going to see

00:07:13.599 --> 00:07:20.800
any kind of difference, it would be in the temperatures. Because while the

00:07:17.759 --> 00:07:22.639
water is still relatively clear, that

00:07:20.800 --> 00:07:26.560
doesn't tell us what our blocks are going to look like. The insides of our

00:07:24.639 --> 00:07:31.360
blocks could easily end up gked up because they tend to have really, really

00:07:28.720 --> 00:07:35.840
tight fins in them that can actually kind of filter out some of the microbes

00:07:34.319 --> 00:07:39.280
that are floating around in the loop. That doesn't mean the loop is clean. It

00:07:37.759 --> 00:07:43.280
just means that the water might look relatively clear even though there's a

00:07:41.440 --> 00:07:49.520
lot of gunk that grew in it and it's gumming up the blocks. So, I'm at about

00:07:46.160 --> 00:07:49.840
just over 30° on my CPU. Where are you

00:07:49.520 --> 00:07:57.120
at? >> I got uh yeah, just under 30, over 30 now. Hovering right around there. Uh 27

00:07:55.199 --> 00:08:02.639
on my GPU and I'm dead. >> Yeah, I'm about the same. My GPU is a

00:07:59.280 --> 00:08:04.639
little over 30°, but the mounting for

00:08:02.639 --> 00:08:07.599
GPU water blocks is so inconsistent that I really wouldn't read that much into

00:08:06.000 --> 00:08:13.599
that. Yeah, we're close enough that this really doesn't matter. >> But it's worth noting that even at two

00:08:11.280 --> 00:08:18.319
months long, this is still a relatively short-term test. And I strongly believe

00:08:16.479 --> 00:08:21.759
based on what we've seen today, that if you were to leave a dirty water loop

00:08:20.240 --> 00:08:26.879
like this running over an extended period of time, let's say 6 months to a

00:08:24.560 --> 00:08:31.759
couple of years, it would absolutely gunk up, become contaminated, and

00:08:29.120 --> 00:08:36.880
ultimately cost you a lot of time and or money to go in and clean or replace your

00:08:34.479 --> 00:08:39.919
parts. So, in conclusion, let's go team water. Check out the link in the video

00:08:38.640 --> 00:08:44.560
description so you guys can help contribute to this amazing initiative to

00:08:42.000 --> 00:08:50.560
get millions of people clean drinking water and let's get millions of people

00:08:47.360 --> 00:08:52.320
this segue. Odo, pause that please. I'm

00:08:50.560 --> 00:08:56.880
ODO. Okay, so the concept here is that ODU

00:08:55.360 --> 00:09:01.040
has all of the apps you need to run your business. Integrated CRM, project

00:08:59.040 --> 00:09:06.800
management, point of sale, even building your own custom app. Uh, ODO can do all

00:09:03.600 --> 00:09:07.360
of that. So, it's like a guy with eight

00:09:06.800 --> 00:09:12.800
arms, >> but he's only got four arms. >> Yeah, but uh that's only because if we

00:09:10.880 --> 00:09:15.920
showed a guy with eight arms, then you know that would look it would look kind

00:09:14.480 --> 00:09:21.120
of weird. >> This looks weird. >> Well, okay. Yeah, but it's uh it's to

00:09:19.120 --> 00:09:26.320
illustrate, you know, the metaphor, >> which is what >> that ODO's full suite of business apps

00:09:24.399 --> 00:09:31.519
is all you need to run your business. It's got everything you want. >> I want to see a guy with eight arms.

00:09:28.959 --> 00:09:36.880
>> Fine. Fine. Um Okay. Show the guy with eight arms. No. Why?

00:09:36.080 --> 00:09:42.320
>> Oh, no. >> Oh, I I was wrong. >> No, no, no to that.

>> Get a free 15-day trial of ODO's all-in-one business solution and see how

00:09:43.760 --> 00:09:48.320
it can make your life easier. I'm ODU. >> If you guys enjoyed this video, why

00:09:47.120 --> 00:09:56.080
don't you go check out the one we did for Team Trees years ago. We made a tree

00:09:51.200 --> 00:09:58.320
planting cannon. It didn't work. Unless

00:09:56.080 --> 00:10:02.320
our goal was to raise money for tree planting, then it did
