Thanks to Solarity for making this video and share to AORUS!
The GIGABYTE Z370 AORUS Gaming 7 has an excellent power delivery for the 8th gen CPUs, though not the best cooling solution. In theory the VRM could handle a 9900K, though how much of a limitation would the cooling solution be? So he wanted to mod it, if needed. Bottom line you can do it and he would recommended actively cooling your VRM with some modded water blocks. Though for most people he would recommend the GIGABYTE Z390 AORUS MASTER!
