GAMDIAS at the 2024 International CES showed off its updates to the Boreas M2-51 and E2-41 lines of tower-type CPU coolers. The new M2-51D and E2-410D, along with their white variants M2-51DWH and E2-410DWH, come with a digital segment display along the top plate. The aluminium fin-stack is slightly recessed, creating room for a tiny bit of electronics, which are wired down to the base. Besides fan RPM, this display puts out CPU temperature, although we're not sure how it goes about doing this.

The easiest way would be to have this display plug into one of the USB 2.0 headers, and for an app to read CPU temperature and fan RPM off the super I/O chip; although we'd be surprised if it's taking the difficult route of localized fan control and its own thermal measurements using a thermistor. Both the M2-51D and E2-410D are nearly identical heatsinks, but differ in heatpipe count—5 versus 4, respectively; and so while the M2-51D is rated for thermal loads of up to 240 W, the E2-410D is rated up to 230 W. The display is hidden behind a tinted polycarbonate panel, so it looks flush. Although not on display at CES, GAMDIAS revealed that it's working on a high-end dual fin-stack cooler that uses the vast top-plate area available to sneak in a true-color LCD screen.
