750+ Watt Turbo Fan Cluster Project From a Dell PowerEdge M1000E Server

This is 9! 12V/7A server fans built into a fan cluster with handles! It is time to wreck some havoc and play with fire and smoke!
I did not realize just how much fire was sucked through the fans until after I saw the photage. As seen in the pictures on the forum link there was some bad damage to the fan blade and wiring. It actually short circuited the DC rails from the fence melting through the insulation. It is also very good at cleaning the work shop floor.

Dell PowerEdge M1000E Blade Server Teardown
I came by a discarded full size Dell PowerEdge M1000E server rack. Full SAN, 2 large blade servers, 4 or 6 backbone switches, all power supplies and fans. This is a system that is about 8-10 years old and had a new price of around 1000000 DKR (166666 $US).
It was all unloaded in a big mess into a container and I only had time/space to take a blade server, all power supplies and fans with me. Hard disks all go to destruction and backbone switches and the M1000E cabinet itself is too big and clumsy to have any real value in the work shop.

Still works great! I used it yesterday to clean out the workshop of dust and leaves :)

You just invented the fastest and most expensive and noisy way to get a potential 'hair-cut' - and you wouldn't even smell it, before it was all gone 👨‍🦲😱

[@KaizerPowerElectronicsDk]

Seems it was pure luck that my hair is intact :D

[@EgonSorensen]

@@KaizerPowerElectronicsDk - if you ever want to build a drone, I would imagine those motors would be perfect. A decent sized rotor, and you're flying. Or not. those things are dangerous - but then, that's another way to get a hair cut, loose a finger or what's worse

[@markhodgson2348]

Omg amazing, this is why i love this subject

[@202Electrics]

wooaah. thats insane!

[@Null--]

You should get some HP C7000 fans. Those things are insane(ly fun).

[@KaizerPowerElectronicsDk]

I hope I find some :)

[@Nielsquake0]

I have bought this xray transformer: @t and I was wondering if it is a ferrite core one. It's heavy so I feel like I should leave the top on and don't check but I'm not sure if there is a way to see it. The pic includes all the in and outputs

[@Flofy387]

I love these server fans. And you can get them pretty cheap on ebay. :D

[@karsnoordhuis4351]

I think i need to go out and find myself a server...

[@KaizerPowerElectronicsDk]

Please find 10 and make a gigantic turbine fan wall!

Ita just 7.5kW :)

Use a big car battery. It can supply a lot of current.

[@karsnoordhuis4351]

@@simontay4851 true but not for the time i would need it. About an hour or two - three

[@douro20]

I have a Nidec Ultraflo 40mm muffin fan which consumes a full thirty watts of power and runs at 14000 rpm. It's actually very quiet for the amount of airflow it generates. It sounds like a hair dryer when it's running and it actually has a start-up sequence which slowly spins up the fan to detect an obstruction.

[@KaizerPowerElectronicsDk]

I tried chopping normal printer paper with this and it will detect just a small strip of it and stop.

[@xa-xii4865]

@@KaizerPowerElectronicsDk is an RC EDF the same power as a dedicated cooling fan for a server

[@harrysmbdgs]

It's not detecting an obstruction, this is the standard behaviour of a 3-phase sensorless brushless DC motor driver. The startup sequence is designed to bring the rotor up to speed from a known starting position and get it in sync with a phase locked commutation loop while it ramps up the speed and reads the rotor position using back-EMF from the same wires used for power. The reason it stops is the same - it detects that the sync has been lost or the rotor is locked and will stop because of that.

[@douro20]

@@harrysmbdgs No, what it does is it spins the fan up slowly for about three to four seconds and then runs up to full speed. I've seen the type of behaviour you refer to before.

[@elektroundco.8384]

The Motor Inside is an Ordinary 3 Phase Motor which has 2 wirds dir wach Phase inlynn for the Curtent... IT IS ONLY ONE MOTOR

[@jannejohansson3383]

I think first those are wires, I was wrong, and that is just good thing.. I have too poor display maybe..

[@jannejohansson3383]

Triggered in wrong Time.. so sorry If you read my first, angry comment. Because I hate wire burner guys so much, I didn't think and watch entire video first.. Relased now because I just simply see it wrong first time. My brains are sometimes too simply. What we or I learned? Don't jump across video, just watch it first before any comment :D

[@TimDousset]

Yeah it's not the most fun when a 1000e chassis goes into panic and you have your head in the back of the rack troubleshooting something LoL

[@KaizerPowerElectronicsDk]

You hear the *click* of the driver, then initial spin up, then stage 1 and final turbine sound stage before you get tangled out of the wires again

[@TD_YT066]

Months of it troubleshooting , you wear earplugs and a shooter's headset and keep your mouth closed, otherwise the noise comes in that way. Those are only the 7A fans, there's 10A ones too, they had 2 rotors.

Put it on top of your barbeque!
