hey all, just got 2 zotac 768mb GTX460's, these are the ones with the slightly higher 710 clock speed. I removed the heatsink to re-do the compound to find that both versions only have an all aluminium heatsink (no copper parts at all like shown on the intraweb) Anyways, i replaced the compound with some MX2 and stuck some old thermalright ram sinks on the VRM's just to cool them down a bit. Looking at the idle temps now...... Card 1 36 degrees c Card 2 20 degrees c ON AIR?! WTF?! and with this all aluminium no copper heatsink and fan at 30% that is crazy! I was worried they had stinged me with the wrong heatsink (as it looks exactly the same as they fit to the GTS450) but I mean it seems to be doing a good enough job!
