Question Low Cinebench R23 score on a 2x360mm cooled Ryzen 7950X ?

[catcream]

Hello! I am getting 32400 multicore on CinebenchR32 on my 7950x and I have no clue why I'm getting such a low score.

My setup is:
Mobo: ASRock B650 PG Lightning
CPU: Ryzen 7950X with Corsair XC7 waterblock
RAM: Corsair 64GB (2x32GB) DDR5 5600MHz CL40 Vengeance AMD EXPO/Intel XMP 3.0
2x360mm radiators with Noctua and Arctic fans.
Corsair XD5 pump+rad combo.

I control my cooling with an Arduino since my motherboard does not have a temperature sensor header, but when benchmarking I used full speed on everything.

Here's my HWiNFO screenshot while running CinebenchR23 multicore: any ideas? Thanks!

Here I have a graph of temp and PPT over time:

Check BIOS if Eco mode is enabled.

Nope, but I could try enabling it and see what happens. If I get lower than 95C with ECO mode then it's definitely my CPU cooler right?

Tried 105W ECO mode and I get 84C when running Cinebench. 33000 points. CPU package power is stable at 145W.

Yes, CPU spikes to 95C and I get briefly get 200W PPT, then it drops and stays at 170W. To me this feels like my CPU block for some reason can only dissipate 170W.

Yeap. Try to run cbr23 in highest priority from task manager, cause your score seems low even for 170w

I'll try it. I just played some Black Ops 6 and got 95C Tctl/Tdie while gaming on 105W eco mode. This should never happen on 2x360mm rads right? My overclocked 6900 xt pulling over 300W peaked at 69C but mostly stayed at 60C.

Tried realtime priority and got 33175. Everything else "froze" while I ran Cinebench but once it was done I saw the score and could move mouse again.

Also I tried cleaning my cpu and block with isopropyl, reapplied Arctic MX-4 evenly with spatula, and used a 0.6Nm torque driver in criss-cross pattern to attach block. Any clues what might be causing these terrible temps?

I'm pretty tempted to just delid the cpu and get the Mycro AM5 direct die block, but it'd be great to 100% know that it's the block's fault.

On 65W ECO mode I average 67.5C running Cinebench, but the score is abysmal as expected at 26000. Here I'm definitely power limited and not thermal limited as before.

Hate to tell you but I told you, that beast need 220-240W to get full performance.

Everything freezing is normal, that's what high priority does, no worries.

I've no idea what your temps are like that don't have a ryzen chip to help you with that, sorry.
