RTX 5090 runs 2°C hotter with thermal paste than liquid metal — Arctic MX-6 vs. stock LM tested

TechPowerUp Nvidia
GeForce RTX 5090 Founders Edition.

Nvidia's RTX 5090 Founders Edition is the first Founders Edition graphics card equipped with thermal metal. TechPowerUp tested the RTX 5090's liquid metal by benchmarking the GPU with its stock liquid metal application against the GPU re-pasted with conventional thermal paste. The outlet discovered a two-degree Celsius difference in temperatures.

In TechPowerUp's thermal testing, the RTX 5090 Founders Edition averaged 77.6 degrees Celsius. After replacing the default liquid metal material with Arctic MX-6 thermal paste, the outlet saw a 1.8-degree Celsius temperature elevation, with an average operating temperature of 79.4 degrees Celsius.
