Hope this helps someone. Feel free to ask me questions
How are VRM temps? Should show under Sensors tab in GPU-Z.

I bought my shim off ebay.. Just type in copper shim and you get loads of results... cheap prices too.

Yeah I got that, but what are the dimensions I need?

I can't vouch for the square even first digit coolers but for the round style coolers like the H50/70/90 on a 7970 the EK shim is perfect.

Thinner shims will equal better temps...I have the EK shim instead of thicker DWoods, which may be why my H70 keeps my 7970 @ 58c full load @ 1175/1600 and I'm seeing 65c+ from other users at similar clocks.

Any chance you could measure your bracket thickness? If you have any idea where i could get a shim of the right thickness as well, that'd be great. Thanks!
Why not just measure your own? Mine is already installed and in my case.

Not good. 96C. Pretty sure I saw it almost hit 100. Any suggestion on how to help this? I have a fan blowing on it, some thermal tape, and a little heatsink... but it doesn't seem to help.

VRM 1 on the 7950 is a single rectangular thing towards the exhaust part, right?

Need help on this one frown.gif

EDIT: I have mistaken something else as the VRM. Will stick on tape to the correct part and see what happens

EDIT EDIT: still hits 104C+. Idk how to fix this frown.gif

Take a picture of your card and post it here.

Are the heat sinks hot to the touch?

The cylinder things are capacitors, the cubes are inductors and the small chips are the mosfets. This area is referred to as the phases and coupled with the voltage controller it is called the VRM. I believe the mosfets are the only ones that really require cooling although I'm not 100% sure. Try putting heatsinks on them and having a fan blow fresh air over them too. I think most people try to keep their VRM temps below 90c, I try to keep them below 80c, but I think 100c is actually acceptable.

This is what I was worried about in concerns to this mod, the AIO will tank your core temps but your VRM temps will stay the same or get worse, thereby still restricting your overclock. I know on my Windforce card there's an entire chunk of aluminum fins with heatpipes that connects to the rest of the heatsink and a dedicated fan right on top of them, not sure if I could drop the temps lower than this cooler already does.

The problem is that I can't find a heat sink small enough to fit between everything. I really need a solution quickly, since I don't feel comfortable playing games until it's nice and cool
