Software and IR results

The first ‘StemOS’ version is being deployed over our sensor boards; this is our modular firmware that can run on both ESP32 and STM32 based testing/sensor pcb’s we’re designing for performing various tests. Next to that we’ve got our IR-measuring device so we can capture IR/heat images of how the heating liquid is behaving inside […]

First Proof-of-Concept

Our Proof-of-Concept is performing above expectations; even without active cooling the system is already stable and at almost the same core temperature as with aircooling. At the moment we’re only testing with loads up to 500 Watts (0.5kW), so by far not in target range. But this already gives an idea how effective the cooling […]

Proof-of-Concept first results

The first version of our immersive cooling cassette was delivered today by our metal manufacturer. Since all tests with the liquids and sensor boards have been successful, we can now start with inserting the first complete server setups into the liquid and perform testing on that. We’ll be using some common brands of mainboards with […]
