A40 Ultimate utilises a 240mm specific radiator which actually has the dimensions of 272 x 120 x 38.5 mm. This radiator is aluminium and features no additional styling by way of colour or design.


Observing the hose in close detail we can see that CRYORIG are using thin rubber tubing. This tubing is something we’ve seen on other units and it is flexible – though strong enough to remain fixed to the radiator with the attachments.


The basis for A40 Ultimate resides in Asetek’s 5th generation pump technology. The top of the pump has a mounting system which houses the 70mm fan and also includes a PWM fan connector to route power from one source.

Attached to the pump there are four connectors – two mail fan connectors, a female PWM connector which plugs into the motherboard and a SATA connector to supply +5v current directly from the PSU.


On the underside of the pump we have the baseplate/block. This is circular in shape and is constructed of copper. CRYORIG has supplied a thin layer of thermal compound paste so that users can get up and running without having to apply this to the CPU themselves. This also takes out of the equation the need to squeeze out the correct amount of paste, this layer is precise and will give optimum results.


The 70mm airflow cooling fan can be attached to the pump in two different orientations – to push or pull air. It’s suggested that pushing air will yield better performance. The idea with this cooling fan is that it will provide some much needed cooling for the areas of the motherboard which tend to lack airflow – such as the MOSFETs, heatsinks, or memory.

To attach, the fan just slots into the small cavity – this provides secure fitment. The cable from the fan connects to the top of the pump.

Over the page we’ll demonstrate how to install A40 Ultimate.
