Re: big coolers

While some of my 2P computers don't have cases either, they do have fans providing airflow in the front-to-back direction of the boards. This airflow is well guided by the shelf and dividers in the shelf. Furthermore, besides the mentioned 40 mm fan on the VRM cooler, there are two 80 mm fans and a ...

Re: big coolers

My dual SP3 boards are sitting horizontally in a shelf and have a broader than usual VRM heatsink, such that I simply laid a 40 mm × 20 mm fan on top of that heatsink. (I also tried a 40 mm × 10 mm fan but that didn't really move any air.) Other than that, I don't have a good idea how to air-cool se...

It would be fairly daunting to try to test each BOINC GPU project at x1, x4, x8, etc. That's not necessary if the PCIe bandwidth usage of many projects was identified before.
