71°C3Measurementtech4gamers.com/msi-mag-z890-tomahawk-wifi-reviewRead 15 October 2026Chart and text: VRM temperatures maxed out at 71 C after a 30-minute Cinebench MT run. Test bench: Intel Core Ultra 9 285K, DeepCool Mystique 360, Corsair Dominator Titanium 2x16GB DDR5-7200, GeForce RTX 4090, BIOS 7E17v1A1. The sensor, the CPU power and the room temperature are not stated. Profesional Review read 65 C from the VRM sensor with HWiNFO and 60 C outside with a FLIR camera, at stock settings in a CPU stress test. This is another test, so only the Tech4Gamers value is stored. The review also shows a CPU plus motherboard power figure that is not stored, since it is not a wall reading.
