Hey guys. I just got the Thermaltake Duorb VGA fan for my 8800 GTS 320MB DDR3 nVidia card. Before buying it, I had applied Arctic Cooling MX-2 Thermal compound on my stock fan and it had cooled the card from 52C idle to 48C idle (No OC'g) When I changed the fan and applied OCZ Freeze thermal cpd, the card now runs at 50C (no OC). What am I doing wrong???? On the internet its says that it should have dropped to at least 38C (Duorb idle) from 48C (stock fan idle). I can't understand this... Help please, anyone?
