Cooler Master unveils “MasterFlow” GPU add-on that lowers system temps

Cooler Master has unveiled a GPU add-on that can lower system thermals by up to 6 degrees

Today’s high-end GPUs can produce a lot of heat, and that heat can be a big problem. For most modern GPUs, that heat isn’t exhausted outside of the PC case. It is circulated inside the case to be exhausted elsewhere. This means that GPU heat can elevate the thermals of your other components, be it your motherboard VRMs, CPU, or memory. At Computex 2026, Cooler Master unveiled its solution to this problem: the MasterFlow GPU accessory.

In effect, the MasterFlow is a GPU add-on that sits above your graphics card. It utilises the “flow-through” section at the end of most high-end GPUs and uses a blower fan to push this air outside of your PC case. This accessory pushes air outside of your PC using the PCIe slot above your graphics card. By doing so, this heat can no longer impact your other PC components.

Cooler Master states that this accessory can lower CPU temperatures by 4-6 degrees. This accessory is designed for use with higher-end graphics cards, such as Nvidia’s RTX 5070 Ti and above. Note that this accessory only works with modern GPUs with a “flow-through” heatsink design.

Note that Cooler Master has not finalised the design of this accessory. Power for the accessory could come through a 4-pin fan power connector or USB Type-C. The MasterFlow is due for release this year at an affordable price.
