Cooling rack-based equipment
Server guys, your time to shine!
For racks of bare components (motherboards, video cards, power supplies), what are some good cooling methods? Can I make the rack out of thick aluminum? The video cards are already on risers, and the machines are built into milk crates for airflow, but the footprint is sub-optimal. I want to be able to put them in racks that maximize cooling while minimizing square footage in the data center cage (which is how I am billed). Any and all suggestions welcome. |

Submerge boards and power supplies in non-conductive cooling oil. That's how lots of the bitcoin miners are doing it. We have a rig here with a radiator cycling oil through it and the tank has many many ASIC miners.

Rack vertically and have the floor tile off to allow the air in, also put vents on the side to suck the neighbours cool air in

Why do you need video cards in servers?

Yes, it's possible to run xserver without a graphics card

I'm going to pass on that, thank you though.

What are you planning to do?
Glad to see you try new things... Hope it's not mining http://m.techspot.com/news/55111-ins...n-iceland.html |

It ain't possible to mine LTC without video card unless you use FPAC and ASIC ain't available yet.

That's what I found when I looked into it yesterday also. A shame, but it seems like a dead end, at least right now.

One cooling method I am currently experimenting with is fast moving fresh air. Filtered inlet at ground level, m/b and GPUs in a sealed box, big-ass fan exhausting out via the roof space. The idea being that even with high outside ambient temps the airflow is still sufficient to draw the heat away from the GPUs. As a bonus it means you do not need to cool the entire room. (Obviously this sort of thing is not possible in a data centre.) |

One other thought. Is the D/C going to be happy about letting you install extreme heat producing equipment that you've self-assembled into a milk crate?

Your datacenter should be able to supply sufficient cooling, you just need to design it so air can flow.
If you have airflow it might be better with less airspace since it well be easier to maintain the flow. Look on eBay or similar for refurbished server hardware, you can buy some older units cheaper than what the chassis would cost you. I know in the past people that was looking for GPU power used a modified PlayStation (or possible Xbox can't remember).

![]() Looking at two different data centers now, so I'm going to have to do the whole song-and-dance again, it looks like. Not using milk carts in the new data centers, though, looking at using these: https://openrigs.com/arianna-grid-gpu-frame |
