For example, do the rubbery "vibration compensators" or rubber screws supplied with Noctua and Nexus fans (and others) make a difference against traditional screws?
How about the anti-vibration pads supplied with coolers or integrated into fans versus allowing the fans to contact the heatsink?
Just wondering since when mounting the Thermalright TY-140s on my NH-C12P I tossed the anti-vibration pads that came with the heatsink and didn't notice a difference. I'm reasonably sure anti-vibration mounting would make a difference for hard drives but not so convinced about fans.
Maybe it also depends on orientation since my heatsink is mounted literally top-down (i.e. fan airflow is straight down) so gravity is having an effect in keeping the fan in place anyway.
