Do Intel s Core i7-3000-series CPUs really need closed-loop liquidcooling? Today we're testing fourteen different LGA 2011-compatibleair coolers on an overclocked Core i7-3960X in order to determinewhose is the most effective. It seems strange to us that Intel no longer includes a cooler withits fastest retail CPUs. This is , after all, the same company that seems to insist that we includeour original boxed cooler any time we send in one of our purchasedprocessors in for a warranty exchange. Instead, it now suggeststhat enthusiasts spend extra money on something that resemblesAntec s K hler H20 620 , but actually costs as much as the larger K hler H20 920 : Intel's own BXRTS2011LQ sealed liquid CPU cooling system. The rationale behind this move does make sense in that the Corei7-3960X and Core i7-3930K are multiplier-unlocked products thatspecifically target overclocking enthusiasts. Enthusiasts typicallywon t settle for anything as underpowered as its RTS2011AC downdraft cooler, and Intel doesn t think hanging two pounds ofcopper and aluminum up to six inches from the surface of amotherboard is a great idea. And while that kind of leveragetugging on your expensive motherboard is probably ill-advised underthe harsh conditions of shipping a machine cross-country, systemsthat are handled gently and don't get moved often tolerate theweight of big, heavy coolers without a problem. We invited every major CPU cooler manufacturer (that's right, allof them) to show off their LGA 2011-compatible heat sinks, andfourteen responded with products ranging from $30 to $99. Thattakes either a great deal of confidence or a great leap of faithfrom the budget cooler companies, since everyone participating inthis piece knew that we'd be basing our evaluation on overclocking.The wide price range allows us to really test how much we need tospend on cooling, and how much we can benefit from spending moremoney than necessary. Following up on our earlier picture story , here s a brief overview of each cooler s basic features,grouped by price first and arranged alphabetically. Please payspecial attention to each cooler s base height, which is measuredwith the intake fan at its highest position, along with thicknessand offset. If the fan overhangs your DIMM slots, its base height(plus around 0.3" for the CPU/LGA package) represents your maximumsupported DIMM height.
