AMD Ryzen 7000/5000 deals for Black Friday The AMD Ryzen CPU pricing finally gets some movement on Black Friday. Although major discounts are still scarce, there’s a deal that stands out: the 12-core Ryzen 9 7900X3D is now priced at $433, marking its lowest cost to date. Notably, this price on Amazon is even below […]
The 7800x3D is a very interesting chip (and the best for gaming, by a notable amount): when I set my system up with an AK620 the default fan curve in BIOS had the CPU fans going at 1800RPM. But with negligible impact on temps, as these chips are designed to run hotter for clock speed. I put the fan curve to like 30% and tested a few games like far cry 6…same high FPS, no throttling, same behavior. At 1800RPM, the game was at like 50-60C. At 900RPM, the game was at 50-60C. Initially I thought “whoa, I somehow screwed up mounting this cooler even with 2 screws and a simple mount kit”, but it’s intended behavior for these CPUs.
So if you grab one and you are used to intel chips, be mindful of fan curves: default fan curves in BIOS are for CPUs that have much different fan behaviors! And the 7800x3D doesn’t even draw much power, under 100W and outperforming a 14700K that can draw 300W…my GPU doesn’t even draw 300W in most cases!
