I'm considering upgrading to this for my unlocked Phenom II 550BE. Does anybody know what Corsair is going to charge for the AMD adapter? Has anybody tested this with a Phenom II because I've heard they can become unstable above 55c when OC'ed? They perform better when cool. I see all the testing with i7's but how do they perform at lower temps like with the Phenom II against a True or Megahalem cooler?
