Custom engineered HAFX side panel for cooling 3x6990's!

[mackminer]

The first image below is of a HAFX case with 3x6990's. Fans included on the HAFX side cases are 1) not powerful enough to blow required air in to cool. 2) The diameter of the mesh on original side case does not cover the whole area cool air needs to blown over.

The below shows the completed solution to be tested this weekend. Fans are 4x120mm DC, with speed controller, dust filter to be added. All running inside a newly fitted air conditioned room. If this one works out well then I will get my other four machines done the same way. Commercial grade routers with backup comms now setup. Rack with KVM's, console monitor etc. to come shortly.

Any questions just ask and I'll be more than happy to help.

Awesome.  I have an older HAFX case, and while the fans it comes with are nice, they aren't meant to cool 100% stressed GPU's.  For the time I've just been pointing another fan at it hoping to cram as much air in there as I can... which has only resulted in a drop of 1-2 degrees.  I'm very interested in how this goes.

My concern is to keep the machines at a steady temp as opposed to having them really cool. 70 - 75 degrees celcius should be good enough.

These delta fans I'm using are designed to run 24/7 aswell.
My setup is heading towards fully professional and I am considering other ways I can use my "datacenter" to make money.

Any ideas?

My datacenter:
Air conditioned room w/ brand new conditioner.
Room is using 7kWh in power with room for expansion.
Dust free enviroment.
Reliable network connectivity with failover.
Real time performance can be monitored remotely

42U rack housing console monitor w/ keyboard mouse.
KVM installed in rack, patch panelled network ports with 19" switch.
Plus other stuff to come.

Well in that case, I'm not sure why your rig is still in a case. Open-Frame + 1 blower (http://www.newegg.com/Product/Product.aspx?Item=N82E16896615090), and I think you'd be done.

You don't see many data centers running servers in open cases with fans blowing air onto them.

Actually running them at that temp would be with about 70% GPU fan speed - thus, preserving that aspect of the card.

johnj - Running the room at 19 celcius (66F) with 60% fan speed keeps all GPU's under 69c (156f)

Wow, those are really great temperatures for running 6 GPUs inside a case! What were your temps before this mod?

The machines would not be able to run anywhere near full potential without the custom cooling.
