Can a custom fan curve save the Jonsbo CR-1400E's performance?
It's honestly ridiculous that I have to worry about my CPU melting in an action game. Every time I unleashed a big move, the fans would suddenly scream like they just woke up from a nap. The default PWM curve on the Jonsbo CR-1400E is way too conservative, letting core temps rocket from 55°C to 90°C - 96°C in a single second, which slammed me into a thermal wall and dropped my clocks from 4.8GHz to 3.0GHz. I tried pinning the fans at 100%, but it sounded like a power drill in my room and temps still hovered around 86°C—a total joke of a solution. I eventually rebuilt the stepped curve, setting 60°C as the trigger for 70% speed and cutting the response time from 2s to 0.3s. Now, peak temps are locked at 76°C - 82°C and clocks stay between 4.2-4.6GHz. I did have a scare where one fan didn't spin up due to low voltage, but bumping the start voltage to 5V fixed it. Fans now stay steady at 1400-1600 RPM.
