Don't know where you are based, but there are heat waves everywhere right now. It's as if global warming was real, y'know?a lot of renders despite the heat
Are you using a desktop rig, or a laptop? I doubt it's the later, but just in case, I have found that one of these laptop coolers you put underneath is useful: why they don't seem to change the GPU temp much, they actually do help with thermal throttling when I am doing renders.
