Anyone else experience lots of thermal throttling?
Seems I can't run Silent Mode for too long without the GPU massively thermal throttling. Even with Performance and Turbo modes enabled, the GPU seems to run at 86C all the time. I've noticed this mainly with games like Final Fantasy 15 and Horizon: Zero Dawn on Med/High/Ultra @ 1080p. I'm sure before it went for off for repair it wasn't this sensitive?
Anyone else exeperiencing thermal throttling in Silent mode? Seems odd that it throttles when the settings should be setup to handle the heat output vs the clock speed limits it sets for the Silent profile?
2000 series GPUs are designed to throttle. So a Silent/Quiet mode is just going to target a certain fan speed and let the components run as fast as they can with the thermal head room that is available.
If performance is worse than before you sent your machine in it may indicate an issue with the thermal interface (paste/pads). But just seeing throttling is not in and of itself a sign of a problem since it supposed to do that.
A bus station is where a bus stops. A train station is where a train stops. On my desk, I have a work station…
The bit at the end with an 87C temp limit is where I changed the profile to Performance/Turbo
Interesting find, seems that the system does not maintain the temperature very well at the desired setpoint of 75C as the core clock speed does not drop from 1260MHz. It then seems to just put the GPU into power limiter and limits the power to 30Watts for a set duration.
I just left a game running with logs going in the background. You can see the temperature creep above the 75C limit for too long and then BAM - power limit. It will then recover when the temperature is below a certain point for a certain amount of time (I'm assuming an integration calculation).
It's quite irritating as the Silent Profile is fine for playing games in (and I often prefer it for the lower fan noise), just seem that the profile needs tweeking a bit.
