This is the best computer fan. And this
this is its daddy. At $422
and with the ability to move nearly 500
L of air per second, the THD 2048HT
is the most powerful PC cooling fan made
by Blowy Matron manufacturer Delta Electronics. We only have a couple of
small problems. First, we need a case that's going to fit it. Oh, I guess we
solved that one already. Second, we are going to have to figure out how to power
it. It draws 600 watts and doesn't even
come with power terminations. Finally,
we're going to have to figure out how to not get our fingers chopped off while
we're working with it. This is going to be a wild ride.
First, the unboxing experience. As an industrial product, the THD 2048HT comes
in fairly non-escript packaging, and they make the assumption that if you
need one, you probably need at least two. This is a master carton that we got
from uh Digi Key. From Digi Key.
And I think the most noteworthy thing about it right out of the box is that
instead of being made of plastic,
the frame is actually constructed from what appears to be cast aluminum. Yeah,
diecast aluminum. Well, that would help explain some of the cost. Like a blowy
matron server fan, it's got an extremely large fan hub. That's to accommodate its
powerful motor. Hey, there's one of them. And like a server fan, it's also
got these airflow guides on the back that I guess couldn't help double this.
Now, that's not going to keep your fingers out of it. On the subject of
putting your fingers in this thing, it spins at a rated speed of 7,400
RPM. And now I can see you guys thinking, well, gee, that's not really
that much faster than something like this. Uh, that thing's 11,000, right?
But even though this spins 4,000 RPM
faster, what it doesn't have is a ton of
inertia. These blades,
these got weight. This gets even
scarier. It's rated at 48 volt DC, but
it'll operate at anywhere from 36 to 75.
Does that mean it'll go faster than
7,400 RPM? Is it DC controlled? We can
find out. Do we have a variable power supply? Imagine we do. Oh my god. This
won't be our highest airflow PC, but
it's going to be like right behind it. And these are way smaller. My first
thought for powering these was no problem. There's cases out there that
accommodate two power supplies. So, we'll just put a second PSU in our
system, wire up some PCI Express power connectors to it, and we're off to the
races. 1200 W of fan. No big deal. Unfortunately, this is not a 12vt fan,
and computer power supplies only deliver 3.3, 5, and 12 volts. This boy runs at
48 volts. So, um, Alex, I see you have a
few different power supply options for us here, ranging from safe looking to
terrifying looking. Oh, no. We need both. So, we have this power supply
right here. 24 volts, 60 amps. Good one.
And then we have these terrifying looking things that we bought off Amazon
because they were cheap. And this is a boost converter. So you put 24 volts in
this side and you get whatever you want out of this side. How do you control it?
Oh my god. It's just potentiometer. Yeah.
Are you kidding me? No, you're not. No.
Why would I be kidding? It's a boost converter. It doesn't even have a
chassis. Who needs a chassis? It has a fan. It's rated for 1500 watts, but
we're we bought a couple of them cuz I don't trust that. How big are those
caps? T in 100vt 470 microfarad. That's
not sending you across the room, right? No. No. Yeah, it's fine. It'll hurt.
Yes. It'll do a lot more than tickle. I wouldn't lick it. I wouldn't touch it.
And literally the control scheme for this thing is to poke it with a
screwdriver. He laughs. I think out of all the
employees, you're the one who's trying to kill me the most right now. Well, no
one else is trying, I don't think. I mean, Dennis fought me. Oh, true. It's
worth checking out that channel. Super fun. And all the amazing behind the
scenes and extras on Floatplane.com. Oh, there's an M4th threaded thing here. Do
we have like a little stand we can put it on or something? Oh, like when we're
just testing it. Yeah. Oh, I feel like our roles have reversed here. I used to
be the one who made you feel uncomfortable. Oh my god, that is not
good. It's fine. It's fine. I want another clamp. It's It moves. It's
barely moving. It's barely moving. It moves. So, when we first turn this thing
on Yeah, you can hide if you want, Brandon,
when we turn it on. Just as long as you have the camera rolling. It's fine. Why
is everyone so concerned about this? It's just a fan. Yeah, by that logic, I
mean, you should just, you know, hang out near jet turbines, right? You
couldn't just get like a variable power
supply like this that does 48 volts. If you wanted to spend like $800 or $900 on
it, sure. Oh, how much for these? 50
bucks. I don't know which is scarier. I'm getting safety glasses. Oh my god.
Do you see how crooked these are? Yeah. It's not the best solder job I've ever
seen. I'm beginning to think the $50 price point of this is a lot scarier
than the $900 price point of the other thing. Ah, thanks. I am concerned about
this thing. Can we get one of the electrical engineers over here to tell Lionus he's being a dummy? A dummy? You
say dummy? What you're looking at right now
is our 1200 W 24V power supply hooked up
to our boost converter. This is going to stay once we're powering the fan.
Because we have no idea what voltage
this terrifying thing is going to output until we measure it and play around with
the little dial. We've got it temporarily hooked up to our Fluke
multimeter. Okay. Wow, we nailed it.
47.87 volts. I was actually playing with
this yesterday to make it work.
This one right here is your current protection. So you can set that to be
like however many amps you want. And this one's a low battery detection. So
if you're using this to charge batteries, you don't want like too low
of a voltage going in here. So this just turns it off. Got it. Before we start
though, important thing. Which one do you want? Oh, I'll take the pink one for
sure. Is this our scientific airflow test? Yes.
Yeah. Clamps. They're really good for holding things on. Hey, Alex. That's
really safe. Remember, whenever you're working with anything that spins, you
want to tie back your loose hair. Okay?
Whoa. Whoa, buddy.
Whoa. Okay. Whoa. Whoa.
Alex.
So, it's drawing 475 watts. Why did we
need two of them? Why not? There's two
fans in the case. You can't drop your number of fans.
All right. Should we check how safe it is? How safe it is? Yeah, how safe it
is. What do you mean check how safe it is? Well, I want to know if you get your
finger or your willie stuck in there, what's going to happen?
It takes a while to get going. It really does.
which maybe is promising from a safety standpoint. It won't, you know, maybe it
doesn't have that much torque when it gets going though. Yeah, it actually
sounds like an aircraft lifting off. Look at the ARM hair.
Wa! These blades are freaking sharp.
Oh, wow.
There's nothing solid. It's just gone.
Look how clean that is. That's terrifying.
Yeah. Yeah. A little bit. And I don't think it slows down at all, Alex.
It's just It just a fine mist gone. What's the
carrot like? Go for it.
It doesn't care at all.
Okay. All right. All right. That's a lot of Alex. It's all over the laser. This
is carrot murder. It looks like chunks,
but it's actually like almost mashed consistency. Wow. That didn't care at
all. Hi.
Was the pun on purpose? No, it wasn't. Could you feel it drawing the object in
as well? Like just from the suction? Not really. No. Oh, I could with the
cucumber. Oh, the back of the fan is
pretty gked up.
If we don't want carrot all over the inside of our computer, we got to get
everything off this. Come on.
Ow. Damn it. That hurt.
That was honestly terrifying. Yeah. Do you want to see how fast it will go?
Yeah. When we put these in the case, I am
legitimately concerned that they are going to overspin the fan on the CPU
heat sink. Oh, we just need to remove the fan. Yeah, it definitely will. Yeah.
And to be clear, that's a problem. So, if we spin that fan in the computer too
fast, it turns into a generator that is actually putting power back into the
header on the motherboard and will almost certainly cause it to light on
fire. Although that actually isn't a thing. They have dodes and protection
and stuff. So, I'm pretty sure it just dumps it to ground cuz I've seen it
happen. How long ago was that? That was a while back. It's still I wouldn't
recommend it. Yeah. Don't do it. Yeah. Also, this is a good board so we're fine. Holy You went absolute top
of the line, Alex. What if we ruin something? What if we blow carrot chunks
at it? Well, no, it's fine. We're not going to blow more carrots. What are
What do you think we're going to do? We're not going to put an i3 in this and be like, "Oh, wow. 65 watts. You can
really dissipate that with these." What we're doing right now is we're putting a
little piece of marking tape on one of the blades of the fan. This is going to
tell our tachometer here how fast it's spinning. Okay.
Now, every time this goes around ow ow
damn it. Oh, that really hurt. Yeah, this is pretty terrifying. Anyway,
here's what I was trying to show you guys. You spin this thing and depending
on how often our marker tape shows up, it gives you a readout. So, if you spin
it faster with something other than your finger, you get a higher number
presumably. Let's figure out how fast it goes. Yeah. From a distance. 4,000
4500 5,000 6,000
6500 7200
Look at the stuff on the other side of the room.
We're at around 7,300 RPM.
Whoa. You see that? It's drawing it in
from the side. What are we at now? I don't think it's getting faster. No, I
think you're right. I think it's controlled. Yeah, it's still at 7300.
So, it does not have DC control. Question then, can we go lower than 48
volts and would it run exactly the same? I don't know. No, it down but not up.
Okay. We've all got goggles on still, right?
All right. Should we put in a computer? Yeah, we should. to help us measure how
much real world performance improvement we can get out of these. We need a new
nickname for these. Sure. Like blowa. Yeah, blowa. It's a little catchier. To
determine just how much performance improvement we can get out of our Blowzukas, we've taken before
measurements for both of our CPU and GPU
temperatures. In this case, with these stock 180 mm cooling fans, it's going to
be a bit of a challenge getting these in here since the mounting holes are
actually in different locations. I'm sure that's something Alex already
figured out. I don't know if you'll like my solution. I mean, based on how much
I've liked everything about this video that has literally hurt me so far. What
are we thinking? We can either do out or
in. I'd say it's got to go inside. If we're going to make the argument that
this is actually a computer cooling fan, it should fit in the case. Okay. Yeah,
something like that. Brandon asked if we're worried about the GPU fans. The
air flow is not going to be directly on them, but there's going to be so much
turbulent air movement that they might be a problem. Yeah, it might be a
problem. So, we're going to need to do something to make sure that we don't get like aluminum bits in here.
Okay. Did you hit the holes? Think it'll fit? I don't know.
That one's perfect. How are you planning to do this? Uh, belt sander.
Good job. Surprisingly clean looking. We
got a flat top. Now, what are these things actually for? Do we know? Uh, no.
Oh, I think electronics cooling. I guess that makes sense. That's kind of what
Delta does. That's what we're doing with it. But like under what circumstances
would you need 5,000 L per second? My
guess is not so much like on a server,
but around a server if you just need to move like a bunch of air into a room or
out of a room. Have you ever actually had to procure one of these through work
or something? Like hit us up in the comments. What are these things for? But
look, won't even be able to tell. Now that is a sleeper. Yep. It's a sleeper
until you turn it on. Oh, we should take the CPU. Uh aha. That would have been
pretty bad actually. I am still pretty worried about even some of these other
fans, like these case fans. There could be enough just air flow coming out of
this case that it'll spin them. Unplug them. Well, I don't know. Let's see.
Wow, they're shockingly quiet when we run them in the computer. Yeah. Yeah.
So, it's 45 dB, but also like it's just
the noise floor in here. It's not that quiet. I guess I should start a stress
test. Yeah, just go for good old Prime 95. Okay. Also, this is an overclock
chip. I played with it a bit. PVO's on.
She goes, "Oh, look at our power." Whoa.
What is happening? Uh, hello. These fans don't know what to do. They're stopping.
There's so much air flow. They're trying to blow air in and these fans are
blowing air through them. Something weird's happening. Something very weird
is happening. Our CPU temps are going down though. So, this one just stopped.
I wonder. Yeah, we might be current limited.
Oh, our CPU is at over 200 watts now. Are
you just cranking the current limiter? Yes. Okay, I think it's enough. I just
want to show you guys coming out the back of the case what we're dealing with
here. Where are we at? Oh my god. Holy.
We're at 1300 watts overload, guys. This
is just the fans. Can you tell it's like
windswept? Who needs water cooling? Got the really
good computer fan here. I guess we don't need any more airflow. Look at her go.
What about we have two of these? Oh, how hot is that thing? Uh, so the wire
currently is at 90°. Oh, I think your
black wire is a thinner gauge than the red one. We can probably fix this. No,
no. I have a solution. We'll just put this here. Active cooling our wires.
Wires are 35°. We're good. Okay, check
this out. It grabs it from out here.
Oh,
and if we like the aesthetics of the original fans, we could just put them
here. I wonder. We can test it. I want to see if you get a back bolt or a back
current. If we get more than 12 volts,
it's spinning faster than it otherwise would have. That's less than I would
have expected. Oh, yeah. It must have protection. That makes sense. Or maybe
we need to spin it the other way.
No, it does. You're right. It seems to have protection. I should put in hearing
protection. You really should. We're at 95 freaking d. Stock is 1,200 RPM.
It's over 2,000 RPM, though. Damn. That's almost double the rated speed of
this thing. And it's not even powered. Are you seeing how dangerous 90 dB is
for your hearing? Barry, you have to remember that every 3 dB is a doubling
in volume because dB are done in a
logarithmic way. So 95 dB is really
freaking loud. You get kind of used to it though. And it's not until it's off
that you go, "Wo,
that was really loud." And holy crap, did this perform better than actually
having a fan on the heat sink. Oh, by a lot. Holy crap. Did we drop almost 15°
by removing the fan from the heat sink?
Yeah. So the red is our before with just a normal NHD15. And you can actually see
here where it starts dropping is when I took the side panel off. And this right
here is when we turn on the blow zuka. You can just see the package power which
was dropping. It's like Yeah. So this is the CPU throttling at 95° right here.
Immediately we're back to actually a greater power budget. So we would get
more performance by adding these fans to
our systems. I think every workstation in the building should probably have one
of these in it. Do you know what we should do before we close this out? We
should run Cinebench ones on it. There you go. All right. Deal with crowd. Air
cooling record. 85
280 230 watts. Not bad.
Oh, I wanted that to be higher. Just like I wanted to tell you about our
sponsor, Vessie. Do you hate wet socks as much as I do? Vesty footwear makes
lightweight, breathable, and most importantly, waterresistant shoes, so no
more squaltchy socks. They're all squinchy. Their Datex material not only
keeps your feet dry, but keeps them warm in the winter and cool in the summer.
The stretchy design shows that comfort is at the forefront at times, making you
forget you're wearing shoes at all, and I love slip-ons. Vessie makes
cruelty-free products right down to the glue, so their shoes are 100% vegan.
Whether it's a rainy city or a rocky trail, the herring bone tread design is
there to help stop you from slipping around. Your feet deserve a little
