Discovered that if i boot from a SATA drive and not a NVMe Drive (i tried two different ones, one connected via USB another directly from PCIe slot )that the mac doesn't go black and fans go full blast when performing Geekbench compute test. Even if i hold down option key boot open core from USB or SATA drive and then click the NVMe drive to run the operating system the results are the same. Videoproc states that hardware acceleration is enabled however when using it for something like upscaling photos or video it cause my screen to go black, fans full blast. I've flashed BootRom with Dosdudes tool. Clean installed w/open core original and with Martin Lo's OC packages. Same results. This started happening i believe w/Monterey.

Think it's unfixable at this point. Just have to get use to booting from SATA for any heavy GPU activities.
