The God of Computer Fans

To answer the question of "What are these fans even for?"

 

It is just a fan.

 

In industry fans are just a thing, a component like anything else.

So if one has something that needs airflow, one buys a suitable fan with the correct voltage, dimensions, mounting, and airflow/pressure required by the application. Often one ends up designing the enclosure to the fan, but the other way around is also common.

 

So in short, it is just another fan.

 

And it isn't even particularly big as far as industry is concerned.

There is far bigger off the shelf fans available that makes these 500 L/s fans seem tiny.

they should just go all in and try this setup with no heatsink on the CPU at all, see if the CPU survives

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

 

 

 

For the record I was working with some super cheap fans the other week, and the LEDs were turning on when we threw a leaf blower at it.

I edit my posts a lot, Twitter is @LordStreetguru just don't ask PC questions there mostly...

What is your budget/country for your new PC?

 

what monitor resolution/refresh rate?

 

What games or other software do you need to run?

in all honesty, this is the most stupid thing i have seen in a long time in terms of work safety. Why wouldn't you cut a fan grill on your laser cutter? one wrong move and your finger is gone. And linus pointed several times at things right in the same direction where the fan was standing. it's not like anyone ever has never hit their fingers on the table when pulling it up from below. 

Jesus and why do you use a buck converter when you all got that glorious lab equipment for several hundretthousend dollars? Were you even using it within its currentlimits? with wires on 100°C, i kinda doubt it, but who knows with that cheap shit nowaydays 

 

edit oh nevermind the wires were your own. for fucks sake. You hired electrical engineers. Use them

I can agree on the fan grill being a wise idea to have. Mistakes can happen far more trivially than one can realize at times.

But the PSU testing equipment are electronic loads, not power supplies. They can't output power, only take it in.
Therefore they needed to make a power supply able to supply the necessary voltage.

Using a boost converter like they did is fine, and honestly how a lot of stuff gets done in industry too. But yes, they should have used a bit thicker wiring.

What model of smaller fan did they reference in the video that was 55 dollars?

Yea, but the video wouldnt be interesting if they did it the safe way /s

Yeah, definitely deploy this in all your editing workstations - because you guys aren't tone deaf and crazy enough 🤣

 

My system is about as overkill as you can get for actual PC fan numbers - I have 30 fans, all running, and yet I can have a totally normal conversation next to the rig. 31 if you include the PSU fan too. They are mounted on five chunky 80mm rads in push/pull, four of them serve just as case exhaust/intake while four more custom order 50mm PWM Deltas do RAM cooling duty. I'm using Swiftech's 8-way PWM splitters for control so ONLY FOUR fan headers on my motherboard are needed to make the whole thing work. As a final touch I set up a HWinfo desktop gadget for real-time temperature monitoring with all my fan speeds 😎

 

And no, my side panels don't get blown off 😉

those fans are commonly used on VFDs, variable frequency drives. mainly big ones with integrated brake resistors.
That and electrical cabinets which need a ton of air volume for some stupid reason.

also tell Linus to quit being a baby, I have one of that exact boost converter that I use to run a 65v LED and I commonly have to demonstrate it's safety by rubbing my hand all over it including the output terminals. 
You are also very out of spec with 24v input at the wattage of two fans. you should be at 48v in or using one for each fan. they are only 1500w near the top of their voltage input rating, which I think is 60

Shere can I purchase a fan with a higher L/S with a semi standard hole spacing?

I thought I had a good fan but no. I am so disappointed with my rig now.

This is a video of my computer under light load.

Why not use an Electric Ducted Fan motor kit intended for RC Jet aircraft?

"Ducted Fan EDF Schubeler DS-86-AXI HDS 120mm"

With the right controller, it might even sound like a jet engine spooling up. I wonder what Linus will think.

37V @ 100A....  IDK what they could even fuckin' power that with....a dedicated 220V circuit in the workshop stepped down?

thats a bit over 15 amps at 240v. I'm certain they have accommodations for such small 240v loads.
