Noctua NH-D15 + Ryzen 5800x - normal temps, but incredible noise
Okay guys. This will be a bit weird.
I've plugged in the LNA (Low-Noise Adaptors) included with the cooler. This, based on the LTT review, limits the fans from 1500 to 1200 RPM.
- My temperatures increased by no more than 1.5'C during stress (and about 3-4'C when idle)
- My CPUId score INCREASED by about 100 during bench
- My Boost clocks during benching are +/- the same (minus 25 Mhz at most)
This was after a 3 minute CPUid test, which I'll repeat over a longer time later on. But this is bizarre to me how a lower fan RPM can yield better results.
The noise is still audible and annoying, but less than before. HWMonitor also reports max speed of 1188 RPM.
Maybe Gigabyte's algorithm for boosting the CPU is also based on the fan RPM, allowing for more power the lower it is at certain temps?
