What watercooling pump do you recommend ?

Solution
Variable speed D5 specifically the Swiftech MCP655, I have 4 pumps, 2 running the 2 operative independent CPU and GPU loops I am running, and 2 shelved backups to swap out in case of pump failure.

Pump failure will eventually happen no matter what brand you buy, having a backup pump covers whether you're down for days vs minutes.
