How to change CPU fan speed on a Predator G3-710

I recently purchased a Predator G3-710, and there doesn't appear to be any way to control the CPU fan speed which constantly runs around 1000rpm. I was able to control the GPU fan with software I found online, but the software doesn't work with the CPU fan. There also doesn't appear to be anywhere in the BIOS to control the CPU fan speed. The CPU exceeds 80 degrees C while gaming, so I'm a little worried this could damage it in the long run.

Does anyone know of any solutions for this? The computer does not come installed with Predator Sense software, and it does not appear to be available for this model. I tried using a link from a different model, but the .exe file said it is not supported by my version of Windows.

Would a different heat sink work, or would it have to be an entirely new motherboard to be able to control it?

Thank you!
