- Modern AIO coolers now contain hardware resembling miniature computers
- Large screens are becoming common features in high-end liquid coolers
- MCUs Now Power Advanced Features in Modern Cooling Systems
Modern all-in-one (AIO) liquid coolers increasingly resemble miniature computing rigs rather than simple hardware designed to draw heat away from processors.
Several recently announced models now include color screens approaching smartphone dimensions, with monitoring software, animations and multimedia capabilities.
In some cases, the screens connected to the processor’s cooling systems are larger than the 4.7-inch screen on Apple’s iPhone SE.
Tiny computers are now integrated into cooling hardware
One example comes from ASUS, whose ROG Strix SLC IV features a detachable 6.67-inch curved AMOLED display running at a resolution of 2400×1080.
The company also offers the ROG Strix LC IV with a smaller 3.5-inch IPS panel, although both products retain extensive customization features.
Driving these displays requires much more than just a temperature sensor, as the displays must process graphics, animations, telemetry information, and user input.
Behind these screens is a microcontroller, commonly called an MCU, which is actually a complete computer integrated on a single chip.
An MCU has its own processor, memory, storage resources, and input-output functions, allowing it to operate independently within larger devices.
Twenty years ago, a high-end CPU cooler was little more than a large metal heatsink paired with a fan or two.
Modern flagship AIOs increasingly incorporate microcontrollers, wireless connectivity, high-resolution displays, RGB controllers, dedicated software ecosystems, and even video playback capabilities.
The result is increasing complexity, with screen-equipped coolers now relying on tiny computers to manage their advanced features.
As features have grown, prices have also climbed, transforming what was once a relatively simple component into one of the most feature-rich devices in a modern PC.
This trend extends beyond ASUS, as manufacturers increasingly compete on aesthetics rather than improving thermal performance.
JONSBO’s TM-280 features a 3.95-inch IPS display capable of displaying hardware statistics, animated GIF files, images, and MP4 video playback.
Meanwhile, ASRock’s Challenger Digital models feature 3-inch LCD panels displaying CPU temperatures, clock speeds, and pump operating information.
Antec has gone even further with the Vortex View 360, featuring a 5-inch rotating IPS display running at a resolution of 1280×720.
Cooling performance now shares space with entertainment features
Manufacturers continue to improve thermal hardware with faster pumps, larger radiators, improved fan designs, and additional motherboard cooling solutions.
ASUS integrates a small VRM cooling fan, while JONSBO rates its TM-280 for CPUs reaching thermal loads of 285W TDP.
Yet the most visible developments are increasingly in displays, lighting effects, wireless connectivity, software ecosystems, and display customization capabilities.
MSI recently showed off a fabric-covered cooler hiding a display beneath its exterior, illustrating how the appearance has become increasingly influential.
Many of these products now rely on dedicated software suites, internal USB connections, specialized controller hubs and proprietary communications interfaces.
The ASUS wireless display implementation even relies on a motherboard connection system carrying power, control signals and data via dedicated contacts.
The evolution remains interesting as these cooling components have evolved into feature-rich hardware that can justify higher prices for enthusiasts building showcase systems.
However, some users may wonder whether such additions are necessary for hardware whose main function remains to cool a processor.
