Overclockers Online has posted a new review on the Rosewill RCX-Z775-EX

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.
