Since recorded time has existed, the most popular way to check the temperature of your CPU has usually been to open third-party software and just look at the reading. Some CPU coolers with RGB fans will let you set it so their color changes according to temperature, but this isn’t universal. Now Cooler Master is working on a CPU cooler that will change colors to show it’s getting hot, allowing you to see the change in temperature with a glance or from a distance. Watching your CPU cooler appear to convert into a molten state isn’t reassuring, but it looks neat. The company is also working on a new 3D vapor chamber to increase the efficiency of its upcoming CPU coolers.
At Computex this year, Cooler Master showed off its current offerings and several concept products pulled from its labs. One includes a CPU cooler with a special coating designed to show off what Cooler Master calls its “super-conductive heat pipe.” The CPU cooler in the demo is a MasterAir MA824 with just a single fan in between the fin stacks, and it’s cooling a Ryzen 9 7950X CPU. In the video below, the fan is unplugged while the system is running Cinebench to demonstrate how quickly the heat rises from the vapor chamber via heat pipes into the fin stacks. It goes to reason that if it took a long time for the heat to rise through the heat pipes, it would be a bad product, but we see the heat rising very quickly and changing the color of the cooler from black to entirely orange in about 30 seconds.
Despite the red-hot appearance of the cooler in the video, the host puts his hand on it and says it’s cool to the touch, so it’s unclear what temps trigger the color shift. It’s unknown what coating Cooler Master used for the demo, but the company is considering bringing it to market for consumer products. It’s something that’s never been done before for a CPU or GPU cooler, and the reason seems obvious to us: It looks like the cooler is melting down almost immediately when placed under load, even though that’s not the case. Still, we’d appreciate being able to know our cooler is frosty at a glance.
The company also showed off the current version of its 3D vapor chamber, which it’s been working on for several years. The concept differs from a traditional design whereby the vapor chamber sits on top of the heat spreader and transfers the heat to the heat pipes, which then pass the heat into the fin stacks. A 3D version extends the vapor chamber into the heat pipes, allowing more heat to dissipate. This could allow for relatively small-ish coolers that could handle over 270W or so, which could come in handy soon, given trends in CPU TDPs lately. Cooler Master will reportedly have more to show off at CES in 2024.
