Improving VRM cooling on FX-8350

Hi guys,
I've installed a closed-loop watercooler on my 8350 but now I'm having problems with voltage drops and FPS spikes (even when simply watching a video, for example). As you can see in the attached picture, cooling around the VRM is less than ideal:

So I'm thinking of switching my ASRock 970 Pro3 R2.0 board with 4+1 power phasing to a Gigabyte GA990FXA UD3 R5 with 8+2 power phasing. Apparently it's a known issue with ASRock 970 boards as they need active cooling for the components surrounding the CPU, so switching to a 990FXA board with a better VRM and included heatsink/heatpipe should (I think) solve the drops in VCore.

Just wondering if I can get any input to how effective this might be as well as other ideas for improvement.

I read that too, unfortunately not until it was too late. Guess I'll remember to read up next time instead of trusting PartPicker to do all the dirty work
:oops:

But anyways, I noticed you also have a badge in Gigabyte, any thoughts on the 990FXA?
