Here is my home site setup
Please note that those fans are 400mm diameter and that there are a total of 3 x 400mm & 1 250mm (2 exhaust and 1 x 400mms & 1 x 250mm intake)
They are commercial grad and move about 2000liters of air a min or second I cant remember which ...long story short it is rather noisy in the rig room
Each one sounds like a jet on spin up which takes about 30-40 seconds until at 100%...lolz
Also that power board is currently taking ~ 16k/w
The room itself is small ... like REALLY small
this is the main reason i have had to go thermonuclear with the cooling & exhaust setups)
Have been through about 10 configs but this is working for now
There is 13 rigs in this room and if you turning off the cooling system it spikes to 45 celcious in aprox 1 min and rigs start shutting down
Currently its sitting on about ~ 23 cel which keeps the fans at about 50% and GPU's are set to 71 cel
IP KVM switch are a must with this many rigs ..also i can remote onto any unit anywhere in the world with a smartphone if i had one ...lolz
Air Intake is going through a 2 way grill setup that is both secure and lets air into a manifold that has 2 intake fans connected
Here is the other end of the intake
Many hours spent sitting here ...lolz
Power Board
2 x 400mm Industrial exhaust and a standard shower unit ...lolz (this is teh exhaust system)
Here is 1 of the 400mm sqaure stack shelfs that I use ..I get 4 rigs per stack
And another
And another blurry rig stack
The second last one is running 5x 7950 per rig ... 5 card rigs are ok but they are very suceptable to heat change and will shutdown or freeze
Anyways with the previous site that I have thats my 45m hash system
A lot of blood sweat and tears and fun
