Can I fix CPU throttling by tweaking Valkyrie V360 pump speed?
Taking off in 4K Ultra settings turned my CPU into a space heater; the coolant temp hit 48℃ in two minutes, which is just insane. The default pump strategy on the Valkyrie V360 MERLIN is way too conservative, so the heat exchange couldn't keep up, leaving my core temps bouncing between 98-102℃. I tried the 'Extreme' software preset, but the pump whine at 3000 RPM was like a dental drill in my room—absolute mental torture. I ended up manually locking the pump PWM signal to a constant 85% and lowered the radiator fan trigger to 55℃. Monitoring with HWMonitor, core temps dropped from 100℃ to a manageable 82-86℃, and my FPS stabilized from a jittery 30-60 range to a smooth 52-58 FPS. I noticed some weird tube vibration at first, but re-routing the cables and securing the rad fixed it. Now the water stays at 38-42℃ with the pump at 2600 RPM and fans steady at 1400-1600 RPM.
