The Hydrae GT series is the directly replacement of our Award Winning QP Series which was considered by many enthusiasts the go-to radiator to use at the core of any custom loop. The Hydrae features like all DIY grade liquid cooling radiators a copper fins/brass tubes construction, an improved tube and fin design that gives these radiator the best performance to noise ratio and makes it shine on an extremely wide range of fan speeds. Practically, this means you can achieve great performance at low fan speed. But it does not stop here. Good performance at low RPM used to require thick multi-row radiators which are always challenging to fit in anything but extremely large chassis. With a thickness of less than 28 mm, the Hydrae GT series is one of the thinnest design on the market, which makes a great choice even for the most compact builds. Last but not least: Quality. The Hydrae GT series features Swiftech's unique premium textured paint which combines both elegance and durability!
