ryzen 3 3200g cpu

The title really says it all, i have the MSI Mag Core liquid 240R on my Ryzen 3 3200g and recently my temp has started to exceed 80 C while gaming. I'm trying to figure out if there's something else causing the high temps or if i just have inadequate components. Any input would be appreciated...

I have an ASUS A320M-K and am trying to run a AMD Ryzen 3200G cpu in it. It will not start. I have tried (2) new MB, different power supplies, multiple memory sticks and am running ASUS QVL memory. Could this be the BIOS problem? I have asked for a BOOT kit from ASUS.
