Rosewill is probably not the first name that jumps into your mind when you think of CPU coolers, but over the past 3 years they have had some successes.  Overclockers Online discovered that their new RCX-Z775-EX is another one.  Coming within a few degrees of the performance of the might Thermalright Ultra-120, and doing it very quietly is not easy.  There is one thing to keep in mind, this cooler stands about 5 1/2 inches tall, so make sure your case is wide enough to accommodate it.
“I think it is safe to say that Rosewill really does take pride in the quality of their products and this makes one believe their other goal of customer satisfaction is followed through as well. As for how the RCX-Z775-EX performed, I think the thermal testing results outline the abilities of this cooler quite well. The overclock I tested at and the cooler I compared the RCX-Z775-EX with would have made a lot of coolers look far inferior but the Rosewill cooler didn’t back down.”
