be quiet! Dark Rock 4 Air Cooler
be quiet! Dark Rock 4 low fan speed I'm just writing this to help anyone else who installs this CPU cooler and gets a CPU fan error. It's okay, the fan on this thing runs slow because the heatsink is so good. I read a review on Amazon saying theirs sometimes stops completely! In my BIOS settings, I turned down the warning to 200 RPM. Temperature is good under full load. Happy days.
