According to Radiate, and guessing on the C/W rating of your CoolerMaster (since you don't have the exact model number), you're temps are right on. The Swiftech MCX462 would drop your temps into the low 40s (~41°C). I would also examine you're case cooling to see what kind of circulation/ventilation you have, if any. I was able to drop my roommates temp 10-12°C just by doing that. Check it out here.
