CPU thermal throttling under XTuple stress test
CPU thermal throttling under XTuple stress test
Hey team, I’ve been testing my i7 4710hq with a 50mV undervolt setting, which is right at its optimal range. Performance has stayed smooth from light to intense gaming, and temperatures have hovered around 85°C at most—still within safe limits. I just re-applied the thermal paste recently.
Last night I ran a 30-minute stress test out of curiosity since I was feeling bored. The system stayed stable, but temps fluctuated between 55-71°C. When the throttle kicked in, it would drop and then restart. The graph I shared shows these ups and downs clearly. It looks like the throttling happens only when the core frequency exceeds 2GHz, then it reverses for about half an hour. My temps never went past 75°C, so it seems okay.
Anyone else notice this pattern?
I've experimented with various BIOS configurations on my work machines. I've observed that restricting fan speeds at certain temperatures leads to unusual performance fluctuations and increased noise. When auto mode is enabled but set to a particular temperature, sudden shifts from silence to moderate operation followed by peak RPM for a short duration can occur, resulting in inconsistent performance spikes.
It was because I forgot to connect my charger during testing, man!
