Hydrogel Coated Heatsinks Significantly Boost Passive CPU Cooling Capabilities

Papers shared on cell report physical science suggests that coating the heatsink with hydrogel provides a ‘significant’ benefit for passive cooling. This paper focuses on testing hydrogel-based moisture thermal batteries (MTB) for passive thermal management of electronic devices such as 100W FETs and 84W Intel Core i5-4690 CPUs. The test results are encouraging, with MTB the electronic components operate about 15°C cooler than with a heatsink alone. Naturally, caveats apply.

In a foreword to a research discussion, scientists from the University of California stated that cooling electronics is a necessary but expensive business, with the main costs being the use of energy and water, and the environmental impact of using those resources. It’s a reminder… Improving passive cooling can be a big boon in reducing this kind of overhead.
