The God of Computer Fans

Being Delta Electronic's most powerful fan we had to try the THD2048HT - aka Blowzooka - out.

I wasn't expecting another janky cooling project from Alex so soon.

[grug_son_of_thog]

Alex is right about the use case. These massive, ultra-high-flow fans are often used for circulation in server rooms. When I used to work at Dell, they had alternating sets of these ducts bringing fresh, cold air into the cold aisles and evacuating hot air from the hot aisles. They were so effective at cooling that people would go on walks around the local lake during their lunch breaks, then stand in the cold aisle directly in front of one of the ducts for a few minutes to cool/dry off before going back to work.

I used to work at a company making these for military and aerospace applications. We made them to cool everything from electronics racks on military planes to the brakes of commercial airlines.

I work in the chemical industry as an electrician, we have similar, though not quite as powerful, fans above all of our switching cabinets, where our PLC's and stuff life inside. They are mainly used to draw the hot air outside, since the cabinets are bottom open, and the floor is usually doubled up for all the thick wiring, where it’s also a lot cooler. There’s also climatization, which cools the lower floor.

Hi Linus, EE here. I've seen fans similar to this used for cooling computer systems that go into airplanes. At high altitude, there is drastically less air so more powerful fans are needed to keep components reasonably cool. These fans are typically all metal to survive harsh environments as well such as extreme hot/ cold (-55C to 80C for example) and intense vibrations.

Alex has gone from being slightly uncomfortable on camera, to being insane and actually making Linus uncomfortable with his ideas.

[WhiteLocust]

I'm a repair tech at a lighting company. We use these guys on some of our robotic light fixtures and some fog machines. The lights get REALLY hot, so much so it melts if the fans are underperforming.

I keep coming back to this video as one of the genuinely funniest, most surreal videos LTT has put together. The crazy wigs for wind effect held back with zip ties, the nuclear-strength banshee cooling fan, Linus’ genuine shock as his cucumber is vaporized at 8:39 in a chapter named “Saftey Test” (their typo, not mine), a vegetable smoothie being sprayed all over a laser etcher, the empty stare and dazed post-adrenaline commitment to more madness at 10:10, stuffing TWO of those fans into a tower for a ridiculously academic and unnecessary benchmark, and using the suction to test normal cooling fans for backvolt protection. That is one hell of an episode on paper, and it STILL is much greater than the sum of its parts. Fantastic content.

The reason it takes a while to spin up is to avoid large current surges. Smaller Delta fans behave like this as well. A motor like this could take upwards of 25A spinning up from 0 if it wasn't for the soft start. Don't worry, these have plenty of torque.

U r right, these are mainly used to move cold air from row coolers to other side of the room. Installed in a cylindrical frame, works like a jet turbine on airplanes. Btw, I am delta electronics employee, every time u features a delta product, I smile.

14:30 - fans like these are used for building static pressure in big data centers sometimes, and also when you need to move air a VERY long distance in a data center. I did some work in some very large finance companies’ data centers, and each “pod” is much larger than a football field. Each “pod” is literally full of server and network equipment racks, and a MASSIVE amount of air must be moved a very long way, so sometimes supplemental fans like these are used if the cooled air from the chillers needs a boost in a tight space to reach the end of a pod. There can be 10+ pods in a single data center too….But usually these are only temporary solutions until the engineers can go back figure out the source issue.

Just think, larger than a football field and 40+ feet high, and they have ridiculous static pressure inside those pods. There is so much air being moved it’s insane.

[ClappOnUpp]

Alex needs his own Mythbusters channel in LMG where he get's to test stuff to their limits. Gpu's melting; capacitors exploding... Nothing survives an episode

[JackJack-okwv]

Just a small correction, every +3dB is not doubling the "volume" but the energy. The feeling of sound volume doubles about every +10dB.

[SeanHodgins]

So, adding 1200W of fans increases cooling performance. Got it!

[Minty]

i didn't buy these specific fans, but when i used to work in a datacenter, these fans would be put at the ends of ducts that lead directly into server racks in order to bring direct AC air to the higher end machines, since they aren't using any water cooling.

[JGFXDK]

14:38 Yes I have.
Food displays in your local super market, heat exchange equipment (chillers etc.). This is for all intents and purposes an industrial product, which is why only places like DigiKey sell these.

[charliebrown]

So I worked at a theme park, and we used these to cool racks. Usually they housed audio amps, lighting controllers, media servers, show controllers, and animatronic PLC systems. My personal favorite use however was mounting one over my tool cabinet, and wiring it to a pressure plate so it turned on whenever I was working at my bench.

[TheBurnsStuff]

This is what I like about this channel. They do things that some of us want to, most of us won't, few of us actually can. The ones that can, just won't.

[nickhubble]

Hello Linus Ive used these professionally. In my use case it was positive pressure of a mountaintop radio base-station. The reason for this was to keep the elements out of the base station. They are super loud when you run about 20 intake fans.
Love your content guys!

This was so much fun. I love how Linus and Alex complement each other with their earnest penchants for ridiculousness. Each has the answer for the other’s "Why?!":
"Why not?!"😅
