A Closer Look at the Corsair iCUE H115i RGB PRO XT

The radiator for the iCUE H115i measures in at 322mm x 137mm x 27mm. Adding the fans will tack on another 25mm to the height. The tubing for the cooler is made from a low permeation rubber and has a nice nylon sleeve over them giving them a nice finished look.

The 280mm radiator has a fin density of 20 fins per inch. This should allow the 27mm tall radiator to cool well. There’s always a need to match the fan type (CFM vs Static Pressure) to the type of radiator used.

The fit and finish of the kit are very good. Nicely crimped connections exit the radiator. You can see the sleeving goes into the fittings a bit. The fittings on both the pump and the radiator are typical for most AIOs and cannot be removed. The iCUE H115i is non-serviceable but does come with a 5-year warranty.

The CPU block and pump combo have a glossy finish to them. There are a total of 16 aRGB LEDs in the pump and are controlled by the iCUE software. There is a micro USB port on the side of the pump that is to be used with the supplied cable and is plugged into an available USB 2.0 header on the motherboard to provide communications between the cooler and the iCUE software.

The underside of the pump is the cold plate. It is made from copper and has pre-applied thermal paste from the factory. There are minor machining marks on the cold plate but nothing that should prevent good contact between the CPU IHS and the copper plate.

Power to the cooler is supplied via a SATA cable. There are two PWM fan headers labeled 1 & 2 for the supplied fans as well as another fan header to supply RPM information to the motherboard.

Two 140mm ML fans are included with the iCUE H115i, more specifically these are the ML140 PWM Premium Magnetic Levitation fans. These fans operate from 400-2200 RPM and push 63 CFM with 3.0 mm-H2O static pressure. Note, these are NOT RGB Fans.

  1. Have been looking to replacing my now “noisy pump” 360 AIO. Per Tom’s review a Corsair H150i RGB Pro XT, 360mm Radiator, Triple 120mm PWM Fans will cost me $181 at Amazon. Moreover the fans are not RGB LED and are quite plain. Then having to purchase extra or missing RGB fans will run me an additional $45 each. I love the Corsair brand…but for their new with RGB fitted AIO costing upwards to $300 is hard to swallow and for many a clear $$$ deal-breaker. It also makes me think that the entire (industry) AIO marketing is going bonkers and needs to return to reality for the man on the street!
