here was a time when your RAM (and maybe a thumb drive) was the only part of your rig likely to bear the Corsair mark. That time is long gone, and Corsair’s triple-mast logo can now be found on power supplies, cases, speaker sets, SSDs, and water-cooling loops—and now, perhaps inevitably, on CPU air-coolers. Corsair’s A50 and A70 air coolers adopt many of the most successful cooler conventions on the market—but how well do they cool?Nearly all of the best air-coolers on the market today are skyscraper designs, in which four or more heat pipes rise from the heat exchanger into a stack of horizontal aluminum cooling fins. Corsair has evidently been taking notes on what works, because the A70 features direct-contact heat pipes like the Cooler Master Hyper 212+ and Thermaltake Contac, and dual fans like nearly every high-end cooler these days.
