We’re kicking off a round of Z890 motherboard tests loaded with the most powerful CPU for the LGA 1851 platform – the Core Ultra 9 285K. We’re doing this with Gigabyte – the Z890 Aorus Elite WiFi7 from the mid-range, or the upper mid-range, if you like… There will be competing models in a similar category later on, but now to the motherboard, which has undergone many changes from the Z790 Aorus Elite AX of the previous generation.
CPU temperature w/o power limits
Disclaimer: The temperatures of the Core i9-12900K, the Core i9-13900K and the Core Ultra 7 265K are incomparable. With the Intel Raptor Lake (Core i9-13900K) and Arrow Lake (Core Ultra 7 265K) CPUs we use a metal backplate, while with Alder Lake (Core i9-12900K), the Alphacool Eisbaer Aurora 360 cooler has a plastic backplate. The latter has lower pressure and the heat transfer intensity is worse, as our tests show.
…and with power limits
