Alphacool is at CloudFest—the world's largest event for cloud, hosting and internet infrastructure! The Alphacool team awaits all interested parties at booth #G10 and #G11. CloudFest, taking place from March 18-21, 2024 at Europa-Park (Rust, Germany), is the go-to venue for professionals to meet, network and explore new partnership opportunities. With so many captivating presentations, important workshops and exciting networking events, this festival can be the kind of experience that can transform businesses in a meaningful way.

An Alphacool highlight is the prototype of a CDU (Coolant Distribution Unit) for servers. With this first model, Alphacool presents a highly effective way of cooling servers on a large scale. The Alphacool 2U 19" Coolant Distribution Unit paired with the Alphacool 4U 19" Radiator Unit has a cooling capacity of up to 8000 watts in its current state of development. This is enough cooling for 40 1U servers, for example. External management is supplemented with in-house software.

That giant radiator unit makes me wonder if there's still a net positive in stacking the radiators that way, allowing the sharing of fans in pull-push-pull configs while saving on space. I recall doing similar in the past; just slightly more ghetto in setup. My main question is if it's better to have hot coolant enter at the front, or at the rear of the stack, since either way, some waste heat will still be dumped downwards from the radiators above.
