Computex 2025 has spawned many interesting and cool PC products for fans of the space to digest, but one that may have flown under the radar of many is a CPU cooler that loosely resembles "proof that Tony Stark has a heart."

For those who don't understand that reference, it's from the Marvel Cinematic Universe (MCU) where Tony Stark (Iron Man) is kept alive and functioning by a device called the Arc Reactor, which is placed into his chest. Ocypus had on display the Sigma Ultra, the company's flagship Closed Loop CPU Cooler (CLC) that features a round design with a true-color LCD display placed in the center.
This cooler instantly reminded me of the Arc Reactor when Ocypus showed me its differentiating factor, its ability for its side panels to open up when the cooler detects high temperatures have been reached. Ocypus told me users will be able to set the Sigma Ultra to stay open, closed, or even open halfway. As for the screen, Ocypus has equipped the Sigma Ultra with a 2.8" IPS 480 x 480 60Hz display with a maximum brightness of 450 nits.


Ocypus told me they are still working out the kinks with the Sigma Ultra, but can expect it will be coming to market sometime soon - hopefully this year.
