Valkyrie V360 MERLIN pump response issues in Unreal Engine 5
Whenever the scene hits heavy raytraced reflections, I get these 200ms micro-freezes that are just anxiety-inducing. The pump logic on the Valkyrie V360 MERLIN has a 1-2 second lag when power spikes to 280W, causing the core temp to flash-fry up to 96℃. I tried the 'Aggressive' software mode, but the pump started sounding like a power drill while the temps still climbed slowly—it was just loud and useless. I went straight into the BIOS and switched the pump header from PWM/Smart to Full Speed, locking it at 4000 RPM to force constant coolant flow. Checking the RTSS frame time graph, those jagged spikes were completely flattened, with frame times settling between 16-21 ms. I noticed the idle water temp rose by about 2℃ after locking the speed, but that's a tiny price to pay for absolute stability under load. CPU peaks are now hard-capped at 78-83℃ with fans around 1500 RPM. Confirmed the smoothness with performance analysis tools.
