There is no absolute need for cooling as the rpi3 will throttle to not exceed the limits. If you want to avoid this then heatsinks alone will not help, you need to assure sufficient air flow (use a fan) too.

The rpi3+ handles this better but will eventually throttle too, but usually not that much.

NetBSD will not do anything, this is a function of the firmware.

Depending on what you start you will probably run out of memory first.
