I am currently running two 660TI SC video cards in SLI. One of them is a RX (03G-P4-3663-RX) that has the stock cooler on it. The bearing of the fan is currently going out and the warranty just expired on the 1st of this month (October 1st 2014). The second card is still in warranty and is a KR (03G-P4-3663-KR) The issue with the card is it has been overheating. I did replace the TIM on the card and it seemed to help as well as dropping down the power target in EVGA Precision X. Once the card hits around 75C+ the system crashes. I am probably going to put in a RMA request on the KR card. Does anybody know of a good solution to do with the bearing on the fan for the RX card or should I start looking at a aftermarket cooler for it?

So is the heatsink on the out of warranty card is going out, is the one -KR part still functioning properly? With the system off you can try spinning the fan with your finger.  It should be light, no resistance should be found.

The fan does produce some resistance when spinning it. The other card has been causing my computer to crash and when it reaches around 75C+ and i have reapplied thermal compound to it. That did seem to help but i had to drop the power target on it down to 80% and monitored the voltage, fan speed and thermal. So far it stays around 50-60C doing that. I have diagnosed the card in another system and it I am able to reproduce the issues.
