As nice and convenient as all-in-one liquid coolers have become, not every system needs the cost, complexity, and risk of leakage that comes with such systems. For those still looking to air cooling to provide relief to hot-running chips without the physical imposition of something like the humoungous Noctua NH-D15, Enermax offers its ETS-N31, a relatively-compact tower cooler with a 92-mm fan.
Enermax seems to have designed the ETS-N31 for maximum compatibility with crowded motherboard designs. To that end, the cooler's three direct-contact heatpipes are canted to provide additional room for memory modules, which tend to be mounted to one side of a CPU socket. Fiddly wire fan clips can be a real nuisance to deal with inside a compact enclosure, so the ETS-N31's included fan has clips integrated into its plastic shroud for one-handed installation.
The trend of compatibility extends to the ETS-N31's socket support, covering Intel sockets with anywhere between 775 and 1366 pins and AMD sockets from AM2 all the way up to AM4, plus the FMx sockets. Yes, this includes support for AMD's latest-and-greatest Ryzen processors. The ETS-N31 measures 4.9" x 3.7" x 3.1" (125mm x 95mm x 78 mm) and weighs in at 13.6 oz. (385 g). Enermax expects the cooler to hit store shelves in late March at a wallet-friendly $20.
