So i got myself the Radeon V540 because im not sure really, ill find a use but i got myself the windows drivers and fixed the pcie bus bridge error (or well only tested it on one of the GPUs since cant , now my only real issue is cooling, any ideas how to do this for a cheapish way and efficiently without making myself deaf?
If noise is a concern then that pretty much rules out axial fans- Larger case fans won’t provide enough pressure and smaller high static pressure fans would get deafeningly loud for something that would sit on or near your desk.
I think your best bet would be to go with a blower though space would be a concern. I’m personally using an optiplex 9010 fan (around $10 on ebay) on a Tesla M40, but with the fan mounted underneath the card and a 3d printed shroud/duct connecting them the card is about 4 slots thick, which you don’t seem to have the space for.
You might be able to get away with this case if you use a thinner fan from something like an AIO pc, but noise and airflow might be a concern there.
