I'm eager to buy an Accelero Xtreme Plus II for my Powercolor 6950. It's not a reference card as you can see from this picture and also these comparing a reference and non-reference MSI 6950 (which seems to have the same layout as my Powercolor), but although the GPU appears to be further to the right, this will just mean that the AXPII extends further off the end of the card, which won't be a problem as I'm building a custom case for this PC. What I need advice with is the VRM heatsinks. The stock heatsink, as shown in the picture, appears to be a copper one, so that might be sufficient and it might be best to just leave that in place. Alternatively, the Gelid enhancement kit might be an option, although the picture of the MSI 6950 seems to show only 4 VRMs with small components in between, which is quite different to the reference card which seems to have 8 VRMs, so I'm not sure the Gelid would be compatible. Otherwise, I could get some Enzotech MOS-C1 copper heatsinks as shown here (again I think I'd only need four of them). I'm concerned about the heatsinked VRM in the upper-left shown in that picture, as it doesn't appear to be present in that location on the Powercolor/MSI non-reference cards, so I need to know whether it's actually absent on my card, or just moved elsewhere as I don't want to start using the card without a heatsink on this component and burn it up Sekisui thermal tape seems to be recommended for attaching these heatsinks and I guess I'd use that on the RAM heatsinks as well, as the paste supplied with the AXPII doesn't appear to be great. I'll probably just use the AXPII RAM heatsinks, as I'm less worried about the temperature of the RAM than the VRMs (the CHiL controller on the Powercolor doesn't support VRM temperature monitoring!), although I might look for some of those Thermaltake copper RAM heatsinks. I'd welcome recommendations for where to get the Sekisui tape (I know it's available on e-bay, but if anyone's found certain suppliers to be reliable or can advise exactly what size/type of tape to get that would be helpful).
