Hey there, just checking if the Noctua NH-D15 fits the 7900x3d. They suggest using a 280 mm AIO, but I’m not a big fan of AIOs since they tend to fail quickly.
We should monitor the results and determine what additional features are required based on third-party feedback.
I’d skip D15 and move straight to FC140. It’s not a good deal to buy D15 in 2023.
You can always run in eco mode and lose 5% in multicore full time rendering (zero gaming impact). Remember it's not the cooler that can't keep up on the 7000x series, it's stock settings are set to run up to 95C if there is any thermal headroom under heavy load. No matter what cooler you use for the most part. Basically if it under load and below 95C, bios stock setting says MORE POWER, regardless of efficiancy/speed/heat, till it hits 95C. It isn't thermal throttling at 95C (it runs above advertised speed settings still). But a better cooler gives you more thermal headroom, allowing more power, maybe giving you more speed- basically trying to overclock, but terribly inefficiant. Using the below video as a guide and upping some of the settings a tad. My 7700X maxes out at 85, runs a few hundred mhz faster then stock and maxes out at 90w... Using a 240mm AIO. --edit-- I forgot to add that 85 was using cinebench, an almost impossible task of max multithread use for most people... Gaming it never goes above 55 under heavy game load... most time it sits at 50 or below gaming and multitasking normal loads.And before the AMD vs Intel game begins, the new intel 13000 does same thing basically...
What offsets did you manage to reach? I'm still evaluating my 7700X, but I've completed Cinebench with a -23 curve offset. At 30 it caused the system to crash when logging into Windows. -25 stayed stable during Cinebench, and I exited the session when 55 seconds remained. After returning, I saw a crash report and the system reinitialized—likely in the final moments. I'm reaching 95°C during testing with a Noctua NH-D15 cooler. I plan to run Prime95 later to check stability at -23 PBO2 offset. This was my first successful run at -20 PBO2, and the next at -23 PBO2.
No need to check that yet. Decide whether to run the curve optimizer before applying the PBO2 offset. A PBO2 offset might influence the outcomes from the optimizer. Also, haven’t set a maximum temperature cap yet. Setting it to 85°C in the BIOS could allow for a larger offset.
