Title: Riser boards, place on what material? Post by: 2econd on June 21, 2017, 03:20:17 PM Hi,
My newest project is a 5 GPU rig inside a 4U server case. It's coming along quite nicely but it's too small to let the GPUs hang. So I need to place them on the floor of the case. I need to make the case a bit higher here, so the GPUs can rest (where the GPU risers are attached). But I'm not sure what material to use. Should I use metal, or is this an absolute no-go. Am I better off using wood? I could also use metal, and let them rest on the rubber that came with the risers. I'm guessing this material came with the risers because it withstands heat, or was it just to protect the boards? As you can see, I'm at loss here. Hope someone can help me out. Thanks in advance!

Use an material which has no electrical conductivity.

Easiest for me is to use wood. I'm afraid rubber might just melt, or is that me being crazy? Title: Re: Riser boards, place on what material?

Hmm, i dont know the exact temperatures for each material, but i'd say if the rubber melts, that temperature would prolly burn the wood aswell... Title: Re: Riser boards, place on what material?

Caps pins will eventually short to the metal frame if no precautions used.

Post by: 2econd on June 25, 2017, 02:19:03 PM I just want to say thank you once again. I've contacted a local supplier of rubber material to obtain some fireproof rubber which I will use to place the risers/GPUs on. Not conductive, but the GPUs are grounded anyway through the cables, so I'm not worried there.
Thank you! :D |
