We tested the 3R System iCEAGE Prima Boss, a CPU cooler with tower design, four 8 mm U-shaped copper heatpipes and a 120 mm fan. Let's see how its performance compares to other coolers we have tested recently.

The Prima Boss's box has a handle at the top and a small transparent window that allows you to see part of the cooler.

Inside the box we fount the heatsink, fan (not installed), user manual, installation hardware and a tube of aluminum-based thermal compound.

The included fan has no automatic rotation speeds (there is no PWM pin on the connector) but this cooler comes with a fan controller that must be installed in one of the rear slots of the case. You can see this controller in Figure 3.
