How to fix CPU throttling with NH-D15 G2 in Lost Ark?
While grinding through massive raids, I noticed these micro-stutters the second I popped a skill, which is a total nightmare when you're chasing a perfect run. My Noctua NH-D15 G2 was struggling with transient power spikes, with core temps swinging wildly between 82°C - 88°C, triggering the boost clock to tank from 5.2 GHz down to 4.1 GHz. I tried lowering the in-game graphics settings first, but that was a complete dead end—the stutters stayed and the game looked like trash. I eventually dove into the BIOS fan control and slashed the fan response time from the default 2 seconds down to 0.1 seconds, while bumping the core voltage offset to +0.02V. Using HWiNFO, I saw the peak temps settle down to a much safer 74°C - 78°C, and the clock fluctuations just vanished. It was a bit of a struggle at first because the fans sounded like a jet engine at idle, but once I dialed the speed back to 900 RPM below 50°C, it hit that sweet spot. Now the CPU is buttery smooth, and my frame times are locked in at 5.1ms - 6.4ms. Still, the G2's bulk makes RAM clearance a constant headache.
