The MCX159-CU had been on my most wanted list for about three months, so when I was getting it for review I wasn't the least bit surprised or disappointed. I had been looking around, and most overclockers use it because it's practical and keeps your Northbridge temperatures at a good level, so you can achieve a huge FSB. I was very pleased with the cooler none the less. From its mounting, to the fact that they include Arctic Silver Ceramic, it's a bargain. Water cooling your northbridge isn't too practical because your Northbridge doesn't respond to temperatures like your processor, just keeping it at a decent temperature will get you good results, going sub ambient or really close to ambient will grab you a couple MHz at most. All in all I found this cooler to be a great bargain and performer.
