just to give an insight, i own an ichill 670. i have had lots of gpu's for the past years, and the I-chill is the coolest that i have ever used.
i mentioned this several times already here in toms, but just to give an idea.
i play bf4, with my old 560Ti, i was having 60+ in temp. but with a 670 ichill playing the same game in the same room, my temp hovers at 49-50. this is at full load. and no it is not noisy, and i agree with the reviews of my card. very very nice
