Title: 3D print for DEC740/750 hardware
Post by: darksideoverland on January 19, 2024, 11:31:44 PM
I made a cooling cover that takes a USB-powered 80mm fan to actively cool a DEC740/750. Please enjoy as you will, all descriptions are in the links below.

Thanks - I printed this out of black ABS - works great. Took my temps from 55C down to 35C!

You guys are creazy to use two 10GbaseT modules with the DEC700. The NVMe is right behind the SFP+ connectors. You never run into issues with the SDD?

When I did some testing with one 10GbaseT module and compiling a kernel I ended up with (temporary) write errors due to the heat. That is without your cooling cover, of course.
