Proper operational conditions for HR-01:

As is the case with any passive cooler, the normal operating range should be from low to mid CPU frequency. Premium condition for HR-01 is when your power supply unit has a 12cm fan placed at the bottom facing the CPU heatsink. An example would be the Antec PSU or the Enermax PSU. As for chassis ventilation, a proper setup would have an intake fan (8cm or 12cm) in the front and a 12cm exhaust fan in the rear as in the case of the Antec Performance series or the Lian Li V1000 series.

If you plan to operate at high CPU frequency, a 12cm fan is definitely recommended for the heatsink. For tips on how to install one, you can refer to this link* for instruction.
