Zalman really innovated with a hybrid cooler model, which fits video cards and
CPUs. The problem was that as a CPU cooler it achieved a very poor
performance.
Because of its great looks and excellent construction
quality, at first we thought it would perform better that
other low-profile CPU coolers we've tested, but unfortunately this
proved to not be true. It performed worst than all other CPU coolers we
tested to date at full load (except for the Intel stock cooler). At
least it has a low noise level. @ Hardware Secrets
