Included with this cooler are two 140mm RGB fans – Aspect 14 PWM. These fans are capable of 500-1700 RPM and airflow of up to 78 CFM.

Both fans have two cables since they offer the option of RGB lighting. Thankfully, Fractal has allowed the 5v RGB (and the 4-pin connectors) connectors to daisy chain which means that only a single header for PWM and a single header for 5v RGB are required, thus freeing up the headers on your motherboard.



The design of the block is very simple – it features a plastic cap which has an anodized finish. This cap can be repositioned as shown in the next section of the review. There is nylon tubing which marries the block to the radiator – we should point out that the pump in this cooler is located in the radiator itself. Although there isn’t a cable pictured, to achieve RGB lighting the provided cable needs to be attached to the side of the block and into the daisy chained RGB (or 5v RGB header on the motherboard).

On the bottom-side of the block, we can see the copper baseplate and pre-applied thermal paste. The circumference of this is unlikely to cater for larger CPUs which fall into the HEDT category. Lumen comes with the Intel bracket pre-installed.


There are various models within the Lumen lineup, under review today is the 280 model which features a 280mm radiator. This radiator is aluminium and as mentioned, has the pump incorporated, the pump is DC with ceramic bearing and can hit 4000 RPM. A cable feeds from this pump (3-pin) and marries up to the pump header on the motherboard.

Fractal has included a re-fill port on the edge, next to the tubing.
