Choosing a killer CPU heatsink for an Intel CPU can be a challenging task, especially with all the different brands and models to pick from. How do you avoid the lemons and pick a quiet performer? How do to know whether one heatsink is really better, or maybe equal to the next? Frostytech.com has got the answer in this months' billboard-sized Top 132 Intel socket 775 heatsinks chart! Intel heatsinks are ranked according to their performance on a 150W heat load, ranging from -50°C to 50°C over ambient! Obviously some of the warmer heatsinks in the chart are ultra-low-noise coolers, but sound level data can be found in each of the full 132 detailed reviews.
