A Closer Look

The Corsair Hydro Series H90 is a pre-filled, sealed, all-in-one liquid CPU cooler that uses propylene glycol and distilled water to efficiently dissipate heat from the CPU. When it comes to installing this unit, users should make sure their case has a 140 mm fan port on the back or top of the chassis.

The radiator used by Corsair on the Hydro Series H90 has 20 fins per inch / 2.54 cm. This is the same fin spacing as on previous Corsair Hydro Series products, like the H100.


The fan Corsair has supplied is 140 mm x 140 mm x 25 mm large and spins at 1500 RPM. It offers a static pressure of 1.64 mm H2O while pushing 94 CFM at just 35 dBA.


The pump on the Hydro Series H90 is rather plain in its design. Users will notice the absence of features like Corsair Link and a fan speed controller. That said, it is not all bad, since it leaves the Corsair Hydro Series H90 with an elegant, minimalistic design. The tubing is also improved over the corrugated tubing seen on previous models and comes with a great deal more flexibility. This flexibility, however, does not weaken its design. The tubing still feels strong, and the connections at the pump and radiator feel secure. Finally, the base of the cooler comes with a pre-applied layer of thermal interface material (TIM); however, it is easy to clean off should users desire to use their own choice of TIM.
