So I've been working on upgrading my g73jh, I have a 920xm, SSD, etc.

Next upgrade is a 7870m which is on the way but I need mod the heatsink for it.

Here is the stock one



Here is the 7870m


The 3 tabs of metal I will be cutting off to fit. Now we get to what I need advice on.

I was thinking of getting a sheet of aluminum and cutting it too for the VRM area on the new GPU and bridging that plat to the main plate/heat pipes for more active cooling.

Would this be effective or just a bad idea? Are there better ways I could cool the VRMs? Should I just add chipset sinks?

Any advice on how to mod this heatsink or similar experience would be great.

Also, should I even bother with trying to actively cool the chokes?

I suppose another question is do I really even worry about the VRMs on a 45w card? I don't plan on doing much overclocking with it and the stock sink doesn't seem to cover the 5870 VRMs except in one spot

A quick sketch of my planned modifications assuming clearance is fine.

I was going to trim of the tabs up top but instead I'm going to modify them to apply pressure to the added plate. It'll cover the VRMs and go around the chokes, then along the side of the card to the heatpipes which I will then use Arctic Thermal Adhesive to connect the plate to the heat pipes.

Green is stock sink
Black is the board
Purple/Redish is mod
