Really good build quality. Thick and sturdy blade flange and a compact and robust flange generally (surprisingly small anyway)
2 Noctua NF-P12 fans included (good stuff), and puts it on "Ultra Low Noise Adapter" supplied with the fans so goes the admittedly slower which reduces cooling ability, but it is silent, and remains incredibly quiet even at load with clearly approved temperatures.
As it cools well with fans at really low speed and full speed, it must then be extremely effective. From past experience I know that the fan does not sound too bad then either.
Noctua makes good stuff as well.
So rugged, cool well, going to get silent.
Then I was pleasantly surprised that an entire tube of Noctua NT-H1 is provided, which is a good thermal compound, so you do not have to run down and buy a tube of MX-5 or Arctic Silver 5 or similar.
However, there is one drawback to the radiator, and that is that the AM3 and AM3 + motherboards anyway (do not know how it looks with different socket) so you can only mount the cooler so that the fans sit horizontally, rather than vertically. If, like me a chassis that has no outlet to the ceiling so it would have been better if cooler could be turned 90 degrees so the radiator blown out the hot air backwards instead of upwards. Regardless so cool that well, and it is quiet, which is why I bought it.
Had an Antec Cooler H2O 620 before the pump broke. Even though I had really quiet fans on it so let it still a bit considering the pump and stuff. The cooler was not much better either purely temperature-wise.
The computer runs more quietly now anyway with NF-P12 deuce on the flange and 1 500rpm Slipstream 500rpm and 1-Gentle Typhoon chassis so the computer is barely audible.
Terrible good cooler considering the price, and considering that the included fans are running at 160: - each to buy loose, and thermal grease 80 - so it's really good. You will not be dissatisfied.
