Is there any way to throttle GPU usage the same way CPU usage can be throttled (e.g., use at most 60%)?

For machines with fans, throttling the CPU is a way to prevent annoying fan noise. Unfortunately, it's not possible to throttle the GPU (at least, I don't know how), so I've had to disable GPU usage on machines where that makes fan noise an issue. It would be great to be able to throttle GPU usage the same way as with the CPU.

Thanks,
Debbie

Yes, that would be great, were it not that that's something the OpenCL developers have to come up with in partnership with the GPU manufacturers, not BOINC. It's at this time not yet possible to only use part of a GPU's compute units, it's either all in or none.

However, there is third party software available to turn the fans down. I use Speedfan under Windows, set to a desired temperature of 72C, so only at that temperature will it start to increase the fans. It runs generally at 74C with just 50% fan speed.
I've set my case- and CPU fans up with Speedfan as well. So even when things are heating up, it's whisper quiet.

There is eFMer TThrottle,
https://efmer.com/tthrottle-manual/

It can be used to limit max temp for GPU.

GPUs are meant to display a video feed in real time so its all or nothing really. There are no interrupts like CPUs as why would an image from 5 seconds later in a video interrupt one right now as an example.
