"The Thermalright SI-128 SE CPU cooler did an excellent job of
keeping the fully loaded CPU cool. This is the first down-draft style
cooler we have seen that offers close to the same level of performance as
some of the larger tower style coolers on the market. For example, when
compared to the Thermalright Ultra-120 (both using the same 2,000 rpm fan),
the full load CPU temperatures were within 0.2°C of each other (well within
the experimental margin of error)."
