Corsair A70 CPU Cooler
Whether you are new to PCs or an enthusiast, when you hear the name Corsair your mind most likely jumps straight to RAM. However, Corsair has been branching out over the last couple of years into more than RAM. Now they have power supplies, USB drives, SSDs, cases, water cooling kits and now, air coolers.
The coolers are the A50 and A70, and today we will be looking at the A70. The A70 is a dual 120mm fan Heatpipe Direct Touch (HDT) 4 heat pipe tower cooler. The A70 will mount up to all the Intel LGA sockets and the AMD AM2/AM3 sockets.
The A70 is a twin fan cooler and Corsair provides two 120mm fans for a push/pull configuration. Each of the fans is rated at 61.2 CFM at 2000 RPM and run at 31.5 dBA. They can also be restricted with inline power resistors to make them run at 50.35 CFM at 1600 RPM and 26dBA each. So the cooler can be quieted down if needed. The fans themselves are mounted to the cooler without spring clips, but with a rubber isolated bracket that can be easily removed by hand for installing and swapping fans if you so choose.
The A70 is a Heatpipe Direct Touch (HDT) cooler. This means the A70 does not have a traditional cooler base; rather, the heatpipes sit right on the CPU itself. With the pipes directly on the CPU the heat can be transferred to the cooling fins quicker. The HDT design also needs larger heatpipes that can flatten for the base. The larger diameter also allow for larger surface area to aid in heat dissipation.
Currently the A70 can be found on sale with rebate for $54.99 plus shipping. This puts it in close range to the recently tested Cooler Master V6 and the Zalman CNPS 10x Performa. So it will be interesting to see how the A70 will stack up.
