More rad always = better Usually the easiest way to decrease temps at a given ambient...or you can decrease noise at the same time without sacrificing cooling (if your ears want you to).

But it doesn't mean a lonely little radiator can't do the job either

The heatdump of an i7 has been overstated, IMO (though for those coming from a Yorkfield, it is an increase in heatdump...but it's nothing we haven't already dealt with in the past few years). Going from an MCR120 to an MCR320+220 stack resulted in a temp drop comparable to (or even less than) the temp drop I had with my QX6700 at 3600/1.49V (going from MCR120 to MCR320+220).....which means the heatdump is "comparable to (or even less than)" that of my QX6700's
