Noctua NH-L9x65 + RYZEN 7950x in ECO mode

Hi, can anywone test or have knolage how Noctua NH-L9x65 handels RYZEN 7950x temperartures in ECO mode, in low PC case? Thank you

I know it’s not exaclty your use case, but I can tell you that it’s kinda able to cool my 3700x with a -0,075mV flat undervolt. If I stress test the system I get near 90°C but not much more. While gaming it gets up to 70-75°C. I really doubt that double the cores, even running at 65W could be cooled.
The formula to calculate the TDP is still the same between the 3700x and the 7950x and they bot use almost the same ⁓87W under load according to Gamers Nexus. So the definitive answer is most likely yes, it will work. Noctua says that the CPU might throttle using this cooler.

That’s all I got, hope it makes sense.

at first I thought that was a NH-L9i and I was like absolutely not

but the x65 might actually be doable, we don’t have one at the office or else I’d try it
