- Modern AIO coolers now contain hardware that resembles miniature computers
- Large screens are becoming common features in premium liquid coolers
- MCUs Now Power Advanced Functions Within Modern Cooling Systems
Modern all-in-one (AIO) liquid coolers are increasingly looking like miniature computing platforms rather than simple hardware designed to draw heat away from processors.
Several recently announced models now incorporate color screens that approach smartphone dimensions, with monitoring software, animations and multimedia capabilities.
In some cases, the screens connected to the CPU coolers are larger than the 4.7-inch screen found on Apple’s iPhone SE.
Small 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 with 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 a simple temperature sensor because the displays must process graphics, animations, telemetry information, and user input.
Behind these displays is a microcontroller, commonly called an MCU, which is actually a complete computer integrated into a single chip.
An MCU has its own processor, memory, storage resources, and input and 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 heat sink combined 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 entertaining increase in complexity, as display-equipped refrigerators now rely on small computers to manage their advanced functions.
As functionality has expanded, prices have also risen, turning what was once a relatively simple component into one of the most feature-rich devices within a modern PC.
This trend extends beyond ASUS, as manufacturers increasingly compete through aesthetics rather than focusing solely on thermal performance improvements.
The JONSBO TM-280 includes a 3.95-inch IPS screen capable of displaying hardware statistics, animated GIF files, images and MP4 video playback.
Meanwhile, ASRock’s Challenger Digital models integrate 3-inch LCD panels that display processor temperatures, clock speeds, and pump operating information.
Antec has gone even further with the Vortex View 360, which features a 5-inch rotating IPS display running 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 complementary motherboard cooling solutions.
ASUS incorporates a small VRM cooling fan, while JONSBO rates its TM-280 for processors reaching thermal loads of 285W TDP.
However, the most visible developments increasingly involve displays, lighting effects, wireless connectivity, software ecosystems, and display customization capabilities.
MSI recently introduced a fabric-covered cooler that hides a screen beneath its exterior, illustrating how the look has become increasingly influential.
Several of these products now rely on dedicated software packages, internal USB connections, specialized controller hubs, and proprietary communication interfaces.
ASUS’s wireless display implementation even relies on a motherboard connection system that carries power, control signals, and data through dedicated contacts.
The evolution remains entertaining because these cooling components have morphed into feature-rich hardware that can justify higher prices for enthusiasts building display systems.
However, some users may wonder whether such additions are necessary for hardware whose primary purpose is still to cool a processor.
