If you’re serious about high-performance computing, you already know that you’ve got to keep your PC’s CPU cool. You need something that not only outperforms your CPU’s stock heatsink, but does it quietly. The Corsair Cooling A70 High-Performance CPU Cooler uses tried-andtrue thermal engineering technology to deliver superior air cooling performance: four 8mm copper heatpipes directly contact your CPU. The contact surface is polished to increase heat transfer efficiency. Two 120mm fans with speed control, mounted on rubberized studs, spin quietly in a push-pull configuration for optimum airflow. The A70 is compatible with all current CPU socket designs, including Intel LGA775, LGA1156 and LGA1366, plus AMD Socket AM2 and Socket AM3.

Very good performance I would say.
The A-70 is very well made and yes, large. I installed it in a Corsair 600T Graphite Case, Which gave me plenty of room except for the top internal 200mm case fan. It was going to be less than an inch clearance from the top A-70 fan to the top case 200mm. So I moved the 200mm to the side mesh panel and installed 2 -120mm fans under the dust filter on top of the case. All fans except the CPU fan were attached to the 4 channel (4 amp) fan controller provided on the 600T case.
A back plate is not required for an AM3+ board. It is a Top case air discharge setup.(North -south if you will). The mount bracket is simple to install. Hook each end with the square opening on the AMD clip retention brackets and rock the lever over to tighten. Took about 5 minutes or less.
I did "Tint", both the CPU and A-70 with Arctic Silver 5. There are very small channels between the 8mm heat pipes and the base plate on the A-70. I carefully filled them while tinting and did not attempt to remove the Arctic 5 that was in the channels. I did wipe very well with a coffee filter to remove the remaining Arctic 5 from the faces of both the CPU and Cooler. I then applied a "pea" sized application of Arctic 5.
The only problem I encountered was the rocking "Arm" that is used to tighten the cooler to the CPU is a little tall (see pictures). I had to mount the back fan maybe 1/8th of an inch high to fit on the cooler. You really can't tell by looking at it however. There is enough play in the fan (Box) to compensate for this adjustment. I have added pictures to the top of the reviews.
As you can see in the pictures, Corsair low-profile 16gbs of ram (4 slots filled) has great clearance from the A-70. And is compatible with the GA 990FXA UD3 board.
Note: The airflow direction is marked by arrows on the fans.
Overall I highly recommend this cooler. Thanks Corsair.
Update: 6/6/2012, As my Arctic Silver 5 sets in, and I have increased my fan speed to 2,000rpm (reducers removed) Idle is 24C at a room temp of 22C, ( Max temp on stability test at 3.9 Ghz is 48C. All 8 cores at 3.9 stabilized. Love this A-70.
These measurements were taken off of AMD overdrive utility.
Update 2: 6-15-2012... At 4.3 Ghz Overclock all 8 cores, max temp was 51C stabilized. Set mobo to "auto fan control" and they spool up and down just like PWMs because bios varies voltage by cpu temp. Works good.
Love this Cooler.
Words of wisdom: If your liquid cooler leaks :( ...well let's not talk about that.
If your liquid cooler stops, thats NO COOLING AT ALL ;( .....let's not talk about that either.
If your Corsair A-70 has a fan STOP.. you have ONE MORE, if the SECOND fan stops.. you have 8mm HEAT PIPES. Just sayin.
For the price of the A50, I'm not going to complain too much. It's a nice cooler for the price for 4 stars overall.
NOTE: This is compatible with 1155 sockets because the CPU cooling mounting system is the same. I installed my A50 with an i5-2500K system.
I purchased this device as it had a similar design to the cooler master 212 but was cheaper. The item arrived with its own ceramic based thermal compound in a tube. I had artic silver 5 so I just threw that away. Applying thermal compound is never a fun job as you have to get it right, and in this case, less is more.
The item required me to unscrew my motherboard from the case to put the mounting bracket in the back of the motherboard to seat it correctly. No problem. Followed the directions and my own experience with things and the job was relatively a snap. Reconnected everything and started my computer
Since the compound wasn't broken in I was a little worried. However thermal levels went immediately down to 28C and stayed consisted. They could get up to 33C under intense load. Quite acceptable.
Now that the compound has had time to break in with heating and cooling cycles, I average 25C idle and 27C under load. Probably could get it cooler if I had air conditioning and the house stayed cooler but that is irrelevant. The product performs to specifications, and it fixed my heating problem under intense loads. I would recommend this product to anyone with a stock intel cooler that pushes their computer far beyond email and word processing, and wants a cpu cooler that can actually perform to avoid damaging one of the most vital and expensive components of his/her computer
