Thank you.  I put a large aluminum heatsink on top of the GPU backplate, in the area where the VRAM is located, joined with a silicone thermal pad with 6w mk of thermal conductivity, however, I cannot get below 106 degrees C.  adterburner is Power Limit 102, cclok 1275mhz and vram +1100 with a hashrate of 120mh.  If I lower the power limit below 102, automatically the cclock becomes unstable and the hashrate drops to 100 mhs.  The truth is that I don't know what else to do.  Thank you.
