Heatsinks for the back of a motherboard's VRM

[Dabombinable]

Long story short, my QX6850 is drawing a lot of power through my P5Q Deluxe's VRM, and even with fans pointed at the heatsinks (1x standalone, 1x connected to the northbridge and southbridge heatsinks via heatpipes), and their support plates behind the motherboard are getting too hot (despite it being 16 phase), so what would be the best heatsink solution for them? Note that its currently running in an open case with 1x VRM backplate exposed (the heatsinks screwed through the motherboard to them).

If you want to go all out you can get a universal waterblock for the VRM  

As for heatsinks you can get small individual or long pieces to with adhesive thermal tape for the CPU area.
