#1, you are OC'ing the i7, so immediately expect your temps to be higher, although Skinnee's tests were done on an OC 920 @4ghz and gave moderately decent temps in the 60's and 70's Celsius. Now, with that in mind, it would possibly be a decent cooler if you never intended on watercooling GPU's...which let me be honest...was my next step once I watercooled my CPU. Regardless, i've seen a few things on the H70 which is supposed to be a replacement for the H50 is supposed to be released soon, but I doubt there are any tests done on it yet. I'd hope it would be better, but I (correction: WOULD NOT) recommend the H50, Thermaltake Bigwater or Zalman Reserator to ANYONE. Sorry, in my book, these are gimmicky attempts to entice entry WC users into coughing up money before they figure out the kits are bunk and not worth the pretty box they come in.
