- Modern AIO coolers now contain hardware that resembles miniature computers
- Large displays are becoming common features in premium liquid coolers
- MCUs now power advanced functions in modern cooling systems
Modern all-in-one (AIO) liquid coolers increasingly resemble miniature computing platforms rather than simple hardware designed to move heat away from processors.
Several recently announced models now incorporate color displays approaching smartphone dimensions, complete with monitoring software, animations and multimedia capabilities.
In some cases, the displays attached to CPU cooling systems are larger than the 4.7-inch display found on Apple’s iPhone SE.
Small computers are now embedded in cooling hardware
An example comes from ASUS, whose ROG Strix SLC IV incorporates a detachable 6.67-inch curved AMOLED screen running at 2400×1080 resolution.
The company also offers the ROG Strix LC IV with a smaller 3.5-inch IPS panel, though both products retain extensive customization features.
Running these displays requires significantly more than a simple temperature sensor because the displays must process graphics, animations, telemetry information, and user input.
Behind such screens sits a microcontroller, commonly called an MCU, which is effectively a complete computer integrated on a single chip.
An MCU has its own processor, memory, storage resources, and input-output functions so that it can function independently within larger devices.
Twenty years ago, a high-end CPU cooler was little more than a large metal heatsink paired with one or two fans.
Modern flagship AIOs increasingly incorporate MCUs, wireless connectivity, high-resolution displays, RGB controllers, dedicated software ecosystems and even video playback capabilities.
The result is an amusing increase in complexity, with screen-equipped coolers now relying on small computers to control their advanced functions.
As functionality has expanded, so have prices, turning what was once a relatively straightforward component into one of the most functional units in a modern PC.
This trend extends beyond ASUS as manufacturers increasingly compete through aesthetics rather than focusing solely on thermal performance improvements.
JONSBO’s TM-280 includes a 3.95-inch IPS display capable of displaying hardware statistics, animated GIFs, images and MP4 video playback.
Meanwhile, ASRock’s Challenger Digital models integrate 3-inch LCD panels that display processor temperatures, clock speeds and pump operation information.
Antec has gone even further with the Vortex View 360, featuring a rotatable 5-inch IPS display operating at 1280×720 resolution.
Cooling performance now shares space with entertainment functions
Manufacturers are still improving thermal hardware through faster pumps, larger radiators, improved fan designs and supplemental motherboard cooling solutions.
ASUS incorporates a small VRM cooling fan, while JONSBO rates its TM-280 for processors that reach thermal loads of 285W TDP.
Yet the most visible developments increasingly involve displays, lighting effects, wireless connectivity, software ecosystems and screen customization options.
MSI recently introduced a fabric-covered cooler that hides a display beneath its exterior, illustrating how looks have become increasingly influential.
Several of these products now depend on dedicated software packages, internal USB connections, specialized controller hubs, and proprietary communication interfaces.
ASUS wireless monitor implementation even relies on a motherboard connectivity system that carries power, control signals and data through dedicated contacts.
Development continues to be entertaining as these cooling components are transformed into feature-rich hardware that can justify higher prices for enthusiasts building showcase systems.
However, some users may question whether such additions are necessary for hardware whose primary purpose remains to cool a processor.
