At the time, it seemed a bit odd to have a PCI-E graphics card with a 4-pin molex connector for 12v power instead of a 6-pin. Having an available 6-pin, but no spare molex connectors...I was stumped for half a moment.
That aside, the stock heatsink was a poor attempt at a cooling solution.
The card seemed delicate. After removing the stock HS/F and then reapplying it along with new TIM while using the same ease as removing an IHS from a CPU, the card spewed artifacts like no other that I've ever seen. New memory pads, new arctic silver 5, a nice vacuum job and still massive artifacts.
