2020 Razer Blade Advanced 15 Overheating

Hey all, My laptop has recently started overheating. I have reset back to factory defaults but nothing is working. Reading on a couple of reddit threads, there are comments in there about people replacing the vapor cooling system with new parts (and it solving the problem). I can't seem to find the part number but it's frustrating I can't use my $3K laptop! Any tips would be greatly appreciated. With a fresh install the fans go crazy just firing up a browser. Nothing else is running in Task Manager. I've used HWMonitorPro and can see the CPU gets really hot really quickly and if I run anything on the GPU it also heats up. CPU is reaching 100 just browsing. Terrified about using it. Thanks!
