Does the DeepCool AK620 struggle with Nightingale at 4K?
Using this cooler for a performance hog like Nightingale is like trying to put out a house fire with a desk fan—ridiculous. On ultra settings, the CPU hits 96℃ almost instantly, dropping the clock from 5.0GHz to 3.6GHz and tanking my FPS from 60 down to 38. I tried cranking all the fans to 100%, but it sounded like a construction site and only dropped the temp by 3℃; a complete waste of time. I finally went into the BIOS and applied a light undervolt, dropping the core voltage from 1.32V to 1.26V, and swapped my rear exhaust fan for a higher static pressure model. Now the peak temps stay between 82-87℃, and the clock stays above 4.6GHz. I tried pushing it down to 1.20V at one point, but the game crashed during scene loads, so 1.26V is the sweet spot. Temps now sit at 75-81℃. Saved the voltage and fan curves to a profile, and it's finally stable.
