A Closer Look

The aluminum radiator CRYORIG is utilizing comes with a high fins-per-inch (FPI) count of 21 (according to my count), and to make the most of it requires high static pressure fans or high RPM fans. Other than that, it's a simple 240 mm radiator similar to those seen with many other AIOs. Unlike its larger sibling, the A40 Ultimate which uses a 38.5 mm thick radiator, the standard A40 sticks with the tried and true 27.5 mm thick design.


The pump housing has a fan clip for the 70 mm airflow fan that plugs into the top of the pump. This should - depending on its orientation - improve airflow across the memory or VRM. Looking at the design, it is obviously an Asetek design with the common round copper base. Some machining marks are visible, and the base is as such not the smoothest but does get the job done. Thermal paste comes pre-applied as well, but is not pictured here.


The QF120 Performance series fans CRYORIG has included have a maximum RPM of 2200 and a maximum CFM of 83. When it comes to the tiny 70 mm fan, it has a maximum CFM of just 25 and a maximum RPM of 3000. In reviews of the A40 Ultimate and A80, the smaller fan did not contribute much to VRM temps on mainstream platforms. However, on X99 and future HEDT systems, it will likely have a larger impact because higher power draw results in higher temps.
