Raspberry Pi - Old Laptop Fan for Overclocked Boards (Best Solution)

Heat sinks are not adequate when squeezing the most out of your Pi. This re-purposed laptop fan runs off 3.3v, is whisper quiet and keeps the Pi under 40°C at idle and will only approach 60°C under benchmarking conditions.

Performance specs:

Clock: 1350MHz (force turbo)
Core: 400MHz
RAM: 450MHz
Overvolt: 5
Governor: 65°C/149°F (sixties only reached during stress testing)

I have a second Pi 3 which I run as an educational web server. The horizontal laptop fan, also at 3.3v, delivers the same results as the vertically mounted unit.
