So I bought this card from someone that doesn't want it anymore. My "ATi/AMD Radehon HD 4870 1GB" have broken. This is my 2nd AMD 48X0 card that failed on me in a row, so I went over to the nVIDIA side. Although this is not an upgrade, but rather a replacement I decided to overclock. I was surprised to see that on the 1st attempt I could overclock the core to 1Ghz and run the shader clock @ 2.0Ghz with Furmark running stable for 10-minutes. However I removed the EVGA cooler to see if I can modify my ThermalRight TRAD2 cooler somehow to fit on this card and I noticed sometihng VERY VERY disturbuing when I removed the thermal paste. If you press the cooler to the card (the original cooler, not the TRAD2) and you hold it up against the light you will notice that the cooler NEVER touches or even makes contact with the GPU in the center. This is not the cooler that is bent, I've placed a small piece of glass on the GPU's heat spreader and I came to the conclusion that the heat spreader on the GPU is not perfectly flat - it looks as if it could be a manufacturer issue and that the heat spreader is a little bit bent. This is not good. Has anyone ever heard of this or maybe know what I can do about this? This will of course affect the efficiency of any aftermarket or even the stock cooler. What thermal paste is the best that I can use or how can I close this air gap (it's quite big)?
