I have the swiftech mc462 w/ delta mc462 and i have my 1.33@1.53 and my temps are about 90 F when just doin normal stuff. 100 F even when full load. Your temps are definetly fine, but i would reccomend gettin an Sk-6 b/c that 1.1 will do like 1.5 easy with good cooling.
also make sure your cooling for your case is good.
