Test System & Test Results
TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
Corsairs A70 jumps right in to the fight and at idle settings, the A70 jumped into a 6th place finish at 49.7°C.
Here is where Corsair impressed me with the A70. If the A50 offered "performance", what was a "high-performance" version capable of? - A 3rd place finish! Sneaking in just behind a TEC assisted cooler and another with almost double the CFM. Quite an outstanding performance! Considering the fans can be changed later to higher pressure fans with more CFM, the A70 may even keep up with the Ninja 3.
With two fans cooling the A70, the noise levels are just a touch higher than the A50. At idle the fan can be heard, but with the panel on and other fans going in the case, it's hard to hear the A70.
With the testing going full steam ahead, the A70 again plays in the averages for the sound levels while delivering some really terrific performance.
