Does the pad from the VRM go off easy ? or will it be destroyed after taking it off. I was thinking to take it from the heatsink and put paste on both sides and put it back. How did you do it ?
Also found some PCI 120mm fan brackets on ebay i will order, because those zip ties just look horrible
Putting thermal-paste on-top or around another thermal-paste does not increase its effectiveness.
The problem with the thermal-paste pad used on the Powercolor VRM heatsink is that it is too thick already. You can carefully remove it, and try reusing it if needed. I recommend completely peeling it off, then replacing it with a better thermal-paste. The heights
of the IC/VRM chips may not even be different, but there are two different chips used, so it may or may not be any differences at all. To be safe, I recommend a slightly thicker (than normally used) use of thermal-paste applied across the bottom
of the VRM heatsink.
I also suggest you replace the plastic spring loaded screws used with any basic nuts and bolts that fits. Just remember not to install them, the screws, too tightly
or else, it would bend the center of the VRM heatsink more off. You can see if its bending when tightening also.
By doing the above, or just replacing the thermal-paste, the VRM temp will drop a bit. I don't remember by how much at this moment, but I did do a few before and after runs with just the a new thermal-paste and also with better screws. Both combination will yield better results, and is very easy and affordable to do.
If there are anything else, simple just ask. GL.
