The Best AIO Just Got Better! I had the opportunity to test out the Drive X2 all-in-one CPU cooler from Swiftech. It was easily one of the best liquid coolers I’d ever seen! Essentially, Swiftech created a pre-assembled custom loop. CLCs pail in comparison to what their units can offer. As expected, the company has improved the design yet again and the Drive X3 was released about a week ago. There looks to be some serious improvements on the design that will likely increase performance, but definitely increases the aesthetic quality.
