If you've followed the PC hardware enthusiast scene over the last few decades, you'll have encountered the name Noctua. The legendary maker of fans and CPU coolers has created some of the most coveted PC-cooling parts around, with them famed for their efficiency, quietness, and reliability. However, the company is notoriously meticulous about developing new products, which is in part why it is only now that it has finally chosen to release a range of all-in-one (AIO) liquid CPU coolers, in the shape of the Noctua NL-LC1 range. The new AIO range will be competing with the likes of Noctua's own NH-D15 cooler - long the best CPU cooler around - to tempt you into ponying up for one of these pricey but powerful coolers. To that end, the NL-LC1 range includes "best-in-class" fans whose speeds are cleverly offset to reduce noise, plus the pump has a "noise absorber" to further help make this one of the quietest AIO coolers around.
