Running on air: I used to

    Running on air:

    I used to have something like this: https://hongguanfan.shop/products/hf-p-series-inline-duct-booster-fan-6-inch-220v

     

    Now I'm having something like this: https://www.ebay.com/itm/121181455603

     

    The side panel of the main unit is removed and the 230 V over 100W blower blows right towards to the GPUs that are installed directly to my Asus WS-99 E motherboard. The GPUs have spacers made of plastic, paper or rubber (whatever I can find lying around the room) on their rear end corners to prevent them from sagging too close together.

     

    I'm running 4 WUs at a time on all GPUs with 60% usage on linux cuda-mps. The source is compiled with "all in" on GPU. One 3080Ti, one TITAN V, two 2080 Ti's.

      So how quiet are those two fans? Part of the reason I am not using the after-market gpu fans I bought was they "howled" and the vendor later confirmed they were "server" fans.

          linkup makes good cables from what I saw. but they are more expensive per cable. especially the gen4 rated ones.

          I would encourage Tom to try them out, and just eat the cost. it'll be cheaper than a whole new platform. and a lot quieter.

          Found them on Amazon.  $50+ / cable.  But they have every length I need as well as left handed, right handed and straight through models.

          They are even in "basic" Black so I can take them to Fancy dress up events...      ;)
