The cooler looks like is made of aluminum, but the manufacturer says the base is copper coated with a layer of nickel.
Three copper heat pipes help in the heat transfer.
The max specified fan speed is 2800rpm, but SpeedFan reported a speed of 3000rpm. So this is the fastest fan among the coolers I’m testing in this review.
There’s a high-efficiency (as the manufacturer claims) thermal interface of the Cooler Master PTK series on the base, but I removed it after my first unsuccessful attempt at overclocking and then tested the cooler with Zalman’s thermal paste, the same as I used with the rest of the coolers. The cooler’s base lacks any polish.
The results of the Cooler Master Hyper L3 were somewhat disappointing. It managed to overclock the Intel Pentium 4 512 only to 275MHz FSB while the CPU temperature rose to 70°C.
