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

[Mads Barnkob]

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!

Deciding on what looks best or gives the best airflow, but eventually went with the arrangement that gave the easiest soldering and routing job for the wires at the back.



Modified all fans with new wires and removed all excessive plastic parts, grills and connectors. Maximum air flow please!



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.



The teardown there came from: *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.
