My computer gets really loud / hot!
Info
For the purposes of this page: hardware utilisation = heat.
Hi. Egglyberts here, switching to first-person voice for this one! So, you're using Keysight, and your computer sounds like it's going to take off or you're getting temperature warnings. This is most common in devices like Macbooks or laptops. What can you do?
During non-render usage (less common)
Consider reducing resolution / graphics preset under Graphics, and making sure you have a framerate limit in place. (C) can be used to toggle a built-in frame rate counter. Ensuring Keysight is running comfortably below its maximum framerate will reduce the amount of hardware utilisation.
During render-to-video (more common)
Nothing. Nothing within Keysight in any case, and nothing that I would personally recommend.
Note
For the sake of completeness: an external framerate limit on Keysight will slow down the Render portion, and disabling CPU cores / underclocking would slow down the Export portion. But please do not do this!
Render-to-video is built to export a video as fast as your system can manage, and will typically max out the GPU in the Render phase and the CPU in the Export phase.
My only actionable advice is to make sure your device is nicely de-dusted and not starved for airflow. If your device has performance profiles for the hardware, consider dropping to the lowest one available.
A small rant
I get this "issue" raised as a bug report surprisingly often, which is why I have resorted to creating a whole page on the Keysight Wiki for what is not a problem with Keysight.
It is fully reasonable for software to assume the hardware is able to run at 100% utilisation safely. Blaming Keysight for overheating would be like punching in 1 + 1 = into a calculator, only to have it explode, and then blame mathematics for the failure of the calculator.
If you're uncomfortable or unhappy with noise / heat levels during full hardware utilisation, take it up with your system manufacturer or simply trust that things are operating within expected tolerances.
Note
Personal note: the hardware industry for laptops and other similar devices really red-line things these days in terms of squeezing as much short-workload performance out of a device as possible... since the majority of laptop users likely never fully load their device with something like video encoding, and better burst performance makes a difference to the average user's day-to-day usage. I dislike this trend, but I understand where it's come from.
