I don't know why anyone would spend a cent on heatsink without first checking to see how it actually performs on FrostyTech.com. This time around Frosty tests Thermalright's Ultra-90 heatsink, and by the looks of things it's one fantastic cooler.. see for yourself.
"Amazingly enough, the Thermalright Ultra-90 heatsink is almost as powerful as the larger Ultra-120 heatsink. As you might have guessed the numbers trailing the 'Ultra' relate to fan size;
92mm or 120mm. Like the Ultra-120, the Thermalright Ultra-90 heatsink is built around three U-shaped heat pipes, a few dozen
widely spaced aluminum cooling fins and a copper base plate.
The heatsink is
sold without a fan, the idea being it allows users to customize it with the fan of their choice. A good low
speed 92mm fan translates into quiet cooling, or a high speed 92mm fan would yield lower temperatures with some sacrifices to sound output.Over the next three pages of this Frostytech
review, we'll tell you if the Thermalright Ultra-90 is worth that $40 bucks or not...
