The HE02 is a CPU cooler from SilverStone that has a tower heatsink, six heatpipes, and can be used in passive mode, i.e., without any fan. Let’s test it and see if it really works well without a fan.

According to the manufacturer, the HE02 can dissipate up to 95 W with no fan at all, 130 W with a case fan near the cooler, and more than 150 W with a 120 mm fan attached to the heatsink.

The HE02 comes in a brown cardboard box, as seen in Figure 1.
