Yeah, already had it undervolted on my previous build (ncase m1 + silver arrow 130). I plan on using only for gaming, maybe 65w will do the job at 1080p, will see. My concern now is that the AXP90 Cu I ordered has a backplate and don't know if this will fit properly with the riser cable and GPU. All the reviews I saw were using the AXP90 full copper without backplate.
I ran a 9700k with an AXP90 + Noctua fan(with the backplate it was a very tight fit but still worked).
95watt TDP
16 second boost to 115watts
0.1v undervolt
all-cores set to 4.6ghz max
with that undervolt and wattage limit all core workloads only hit about 4.45ghz, but I was only gaming anyway
gaming temps were anywhere from 65c in light games to 90+ in bf2042
