I took a look at the new BFG Technologies 8600 GTS OC2 graphics card last month, but it’s worth another look. Kyle over at HardOCP has taken the cooler apart to show you the detailed changes inside and whether or not the new cooler is up to snuff.
The BFG ThermoIntelligence unit has an obvious advantage in terms of heatsink surface area. The heatsink fins are more tightly packed together and then extend to a fourth side which the stock HSF does not have at all. You will also notice that the ThermoIntelligence unit has a functioning heatpipe that mates the fins to the copper heatplate. This should be a more efficient manner of moving heat off of the heatplate and to the fins than a set of simple copper strips as we saw on the stock unit.
