The Kuhler H2O 920 is a nice unit. The hoses are 13 inches, and the pump power wire and USB cable is 12″ long. So mounting the radiator and still reaching the CPU socket should not be an issue with most cases. Some small cases there could be an issue with the hoses being too long, same for really huge cases and the hoses being too short to mount the radiator in the top of the case. Mounting to the rear 120mm fan port, the 13” tube length should be just right.
There are two power leads and a USB cable coming from the pump housing. One power lead is for connecting to the motherboard. The other is for connecting the fans to. This means that the Kuhler H2O 920 will only take 1 motherboard fan header. The USB cable connects to an open USB header on the motherboard as well. This is how the Chill Control V software will communicate with the cooler.
The Kuhler H2O 920 has a nice low profile pump and cold plate housing. The housing is only 1.1” or 28mm tall.
To aid in installing the kit the tubing is connected to the pump with 90 degree swivel fitting. Now unlike the Kuhler H20 620 we recently looked at, on the Kuhler H2O 920 the Antec logo is back lit with a color adjustable RGB LED. This is adjusted in the Chill Control V software.
The Antec Kuhler H2O 920 also has soft flexible rubber tubing, rather than stiff corrugated tubing. The soft rubber tubing is very flexible, and can have a rather tight bend radius. Corrugated tubing is very stiff in comparison, so the flexibility will make it much easier to install.
The unit comes with thermal paste pre-applied to the base of the cold plate.
With the stock paste out of the way we can see the cold plate for the Kuhler H2O 920 has a nice finish to it.
Like with the Corsair H70 the Kuhler H2O 920 has a thick single 120mm radiator. The radiator is 2” or 50mm thick. When paired with the included fans the mounting thickness is 4” or 100mm. I set the 920 and 620 radiators side by side so you can get a goo feel for how much thicker the 920’s radiator is compared to its little sibling the 620.
The fans that come with the Kuhler H2O 690 have an operating range of 700 to 2400 RPM, and push 110 CFM at full speed. This is different from the fan that was included with the Kuhler H2O 620. It was a 120mm 7 blade fan that ran a 2000 RPM and pushed 81.3 CFM.
