CoolerMasters are very decent coolers for the money. They are not meant for extreme overclockers at all, but for a basic home user with no plans on overclocking, they usually do well.
BTW, you must have incredibly sensitive ears to think that those fans are loud...! I used to have a Black Label Delta fan, and I was pleasantly surprised as it was nowhere near as loud as I had anticipated. To tell you the truth, my 80cfm Sunon 120mm fan was much much louder than the Delta.
