The stock cooler is performing great and quite. Fan speed at 40% my card idles at <60C and load at around 78C. I wonder whether changing the stock thermal paste to AS5 will further lower down the temps? Removing the stock cooler looks tough for me and I'm not sure whether the thermal pads for the VRM and RAM can be used again. Currently my card is clocked at 738/1782/1053. I cant go any higher because of artifact in ATI Tool. I'm not sure whether heat is limiting my OC or the card has reached the limit.
