Rosewill RCX-Z2-EX Heatsink Review
Rosewill RCX-Z2-EX Heatsink Review
  82%   
Abstract: The Rosewill RCX-Z2-EX is pegged as a low noise heatsink, and with its PWM fan able to scale between 800-2400RPM this is quite an asset.

Information on Frostytech's test methodology is available here.
The Heatsink Fan:
The seven blade 92x92x25mm PWM fan spins at 800-2400RPM, producing as little as 35.4 dBA according to our measurements. The lack of any fan guard presents a challenge for systems with many loose wires dangling around inside the case, but this also allows the Rosewill RCX-Z2-EX heatsink to operate more quietly. The fan draws power from a 4-pin PWM compliant motherboard fan header. When connected to a standard 3-pin fan header it defaults to full speed. The fan frame is translucent plastic, and the outer ring is performed quite substantially. It is not LED illuminated.

Heatsink Top:
With the clear plastic fan removed, the simple construction of the Rosewill RCX-Z2-EX heatsink is evident. The four 6mm diameter heatpipes overlap the base of the cooler completely so as much heat as possible is absorbed at the copper base. The heatpipes fan out to transfer the heat to different sections of the 0.3mm thin aluminum fins. Each fin is spaced 1.2mm from the next. The entire heatsink has received a dark nickel plating.

Heatsink Side A:
From the side we can see the 69mm tall Rosewill RCX-Z2-EX heatsink is composed of aluminum fins measuring 28x60mm and 35x104mm on average. There is about 27mm clearance at either edge of the heatsink for adjacent components. Note the large 14x17mm vents in the side of the fan frame.

Heatsink Side B:
The four 6mm copper heatpipes run from the heatsink base plate in evenly spaced increments. The two outer heatpipes travel a further distance, so more heat is concentrated at the center portion of the Rosewill RCX-Z2-EX heatsink.

Heatsink Side C:
The copper base is ~7mm thick, and soldered to each of the four copper heatpipes. In the way that the aluminum fins are assembled, it is actually the copper heatpipes that hold much of the Rosewill RCX-Z2-EX heatsink heatsink together. The wide fin spacing almost ensures a relatively transparent heatsink, and little airflow resistance.

Heatsink Base:
The dark nickel plated copper base measures 36mm x 36mm where it makes contact with the processor. The copper base has been machined flat, and very smooth. Surface roughness is on the order of ~16 microinches, which is considered excellent. The arrangement of the heatpipes is clearly visible here.
