It turned out one of the mounting screws had poor threads, so it was removed a bit but still only a few millimeters. This caused the AIO not to sit correctly, which could have been fixed with a pair or pliers to add more threading. I recently built a PC with these components: CPU – Ryzen 9 7900X, Motherboard – Asrock B650E PG Riptide WiFi (ATX), RAM – G.Skill Trident Z5 Neo 64GB (2x32GB) at 6000Hz CL30, AIO – Deepcool LT720, PSU – Corsair SF850L, Cinebench R23. The performance was: Multi-core up to 4000-7000 MHz max, single-core up to 1500 MHz on average. Screenshots of the hardware info are attached. It seems CPU speeds never go above 3000MHz during multi-core tests. On single core they reach 4000MHz but don’t last long. I changed BIO settings to use EXPO for RAM and enabled PBO. All drivers, including motherboard and chipset, were updated. Any suggestions? Updated on December 8, 2023 by Catalstiyx
Check the pump by monitoring temperatures and performance. You identified thermal throttling by observing reduced output or overheating behavior under load.
You're not taking any action and the processor temperature is at 95°C. The typical clock speed is only 800MHz. The fastest approach would be to check if the pump vibrates when the system starts up. If it doesn't, the pump is likely dead; if it still works, it might indicate a faulty CPU mount or similar issue.
Pump isn't shaking, so it seems the pump isn't starting. Do you mean the issue is with the AIO? EDIT: System info and BIOS indicate the pump spins at 3103 RPM and during Cinebench it gets warm while the pipes stay cool.
Check if the pump isn’t shaking and verify the reported RPM isn’t coming from the fans. Also consider that the AIO might not be properly connected to the CPU.
