FWIW, the Canakit case with fan using 3.3 volts is inaudible over normal
suburban background noise and seems to provide reasonable cooling.

I bored out the Raspberry logo to admit more inlet air to the fan, the openings
in the case
seem to provide adequate exhaust to keep the CPU below 70 C even without
mounting the
provided heatsinks. Right now it's 43 C, running Chromium with 5 tabs open.
