Up and until a few years ago most CPU cooler manufacturers didn't pay much attention to all the consumers around the world who asked for new heatsink designs that wouldn't interfere with tall memory modules and mainboard components. Now i don't really blame the people who designed those CPU coolers since back then size was what would sell to gamers and overclockers alike and if you happen to recall the huge V10 by CoolerMaster (or even the V8) then you know what i mean. Well the arrival of the AIO liquid CPU coolers changed all that since they offered zero clearance issues without asking nearly as much as custom water cooling kits. This "forced" manufacturers to take a new approach towards CPU coolers so in the past 2 years we've seen many models claim to offer zero clearance issues with your memory modules and mainboard components (and most actually deliver what they promise). The TRUE Spirit 140 BW Rev.A is the latest CPU cooler by Thermalright to feature a "slim" heatsink to allow use of even the tallest memory modules and today we're taking it for a ride.
