to get higher speeds you need to put more vcore , which the HR-03 can handle for the core , but not for the voltage regulator chips .
I have an HR-03 on my 2900pro, and your right about the VRM getting hot, one quick little improvment is replace that crap thermal tape they have on there, I scraped it off with a razor and used the heatsink compound that came with the HR-03, put a thin layer on the sink and a thin layer on each vrm chip. This saved me 20c on VRM load temps (yes 20c). I could have probablly used AS5, the VRM's are in an acrylic housing and saved a couple of more C.
