MSI showed off a next-gen GPU cooler concept at Computex — diamond composites, rifled heatpipes, full metal fans

MSI brought a concept cooler design to Computex — not a product you can buy, but a preview of what next-gen GPU cooling could look like, probably no earlier than 2027. The company is celebrating its diamond anniversary, and it's leaning into that theme quite literally.

The concept packs four main upgrades: full metal fan blades, rifled heatpipes with an internal spiral structure, diamond-composite thermal pads sitting on top of the memory modules, and a diamond-copper composite contact plate at the base. Ditching plastic fan blades means no warping at high speeds and a more rigid structure, which MSI says should improve cooling efficiency — and they feel noticeably cool to the touch. The rifled heatpipes increase the internal contact surface area for better thermal transfer compared to standard smooth-bore designs. The diamond powder mixed into both the thermal pads and the baseplate boosts thermal conductivity in both components — the baseplate looks a bit rough and dirty next to a standard all-copper version, but it catches the light and apparently cools a little better. Combined, MSI estimates all of this shaves roughly four degrees Celsius off peak GPU temperatures.

Four degrees might not sound like much, but at the high-end it matters. The obvious catch is that more exotic materials and more complex manufacturing will push up the cost of the cooling shroud — and by extension, the card itself.

The RTX 5090 on display at the booth looks great, but it's purely a showpiece — you can't buy it regardless of budget. If these cooling features make it to retail, the RTX 6090 generation is the realistic target. Until then, it's something to look forward to from a distance.
