X99: is additional cooling for heatsinked VRM's necessary?

I believe my old q9550 rig died because the bare VRM's burned up because of my overclocking (upwards of 4.2 GHz).

So does anyone worry about the sinked VRM's on x99 motherboards? On my motherboard, I can't really see any easy way to attach fans to the VRM heatsinks because they're jammed up against my large twin tower heatsink (a phanteks PH-TC14PE)).

No, it isn't an issue, assuming you have any case airflow at all.

My X99 board puts out a fair amount of "waste heat" at my 4.3 GHz overclock.

That said, the VRMs do stay in the safe range.

As ATMINSIDE stated, if you have good case airflow you don't need to worry.
