Unlike your typical streamlined 92mm atmosphere cooler, the Phononic Hex 2‘s has a 35W thermoelectric cooler (TEC) embedded in the base, which is powered by a 6-pin PCI-E connector on the side of the heat sink. The TEC component passes a current through a semiconductor, which gets chilly on one side and hot on the other, thanks to the Peltier effect. The Hex 2 is fundamentally designed to offer all in one (AIO) liquid greater functionality in a streamlined 92mm heat sink. Obviously, condensation is an problem when you cool a device below ambient room temperature, but the cooler’s Standard mode enables on board temperature sensors to restrict the TEC’s power, preventing the base from becoming overly chilly, averting condensation and just ramping up to complete cooling power when the CPU is under load. When the TEC is not enabled, the unit relies on an internal92mmfan, heat sinka nd heat pipes. Other modes are selectable in the Hex 2’s software suite, which joins to the cooler via USB, as well as gives you control over the LED colours.
Mad mode implements complete TEC electricity at lower temperatures, and the delta T lost by 5°C when idle as soon as we enabled this mode. Nonetheless, Phononic warns against using the Mad mode in temperatures above 25″C to prevent condensation – a High Surrounding mode is for accessible these scenarios. Ultimately, the Smart Set manner enables you to customize these settings for your own surroundings – as every location differs, we have only analyzed the Crazy and Conventional manners. The cooler itself is streamlined and quite nicely made, plus it is simple to install with an easy rear plate and CPU side mounting plate. The PCI E power connector may not fit between the cooler and your graphics card, though, so you might have to rotate the heat sink 108 degrees so the cable points upwards. Meanwhile, the fan has a 4-pin header and is controlled by your motherboard.
The cooler is not especially silent at full speed, but the fan is not as loud as most AIO liquid coolers we have heard. With the fan at lower rates, though, it is close to hushed and easily a match for Noctua’s similarly sized NH D9L. The TEC surely helped the Hex 2 to improved the Noctua also – by 3°C on our LGA1150 rig and 4°C on our LGA2011 system. It came close to improved Corsair’s H75 overly -astonishing forsuch a little cooler.
The Phononic HEX 2 performs better than equivalently sized air coolers, it keeps pace with AIO liquid coolers and it is easy to use, although it is also clearly market. Noctua’s NH D9L offers considerably better value for money for little overclocks, but if you want more cooling power in a tight space, and an AIO cooler will not fit, the Hex 2 is a amazing if costly choice.
