Compared to some heat sinks which are nearly a kilogram in weight, the Zalman is close enough to the recommended weight not to be a problem. 80 grams is nothing really.
And from THG:
The Zalman CNPS9500 LED is the clear winner of our test, offering very high cooling performance while producing very little operating noise. The manufacturer offers an eye-catching design with fan speeds that can be throttled back to comfortable levels using the bundled Fanmate 2, all while not seriously impacting performance.
Yeah Trig. What crap advice I'm offering!
