I recently came across a galaxy gtx560ti. I purchased the card for a friend, so I started stability testing as soon as I got it. The instant I turned on a game temperatures quickly rose to 90C (it would have continued to rise) with fans manually set to 100% before i stopped the test. My first instinct was to replace the tim with mx4, which resulted in lower idle temps, but the card still quickly climbs to 90C. The temperatures return to 30c after testing is stopped. The card is not warped, and the heatsink appears to be making good contact. Is the heatsink defective? There seem to be many reports of gtx560s overheating (or experiencing heat related failure), on the product page(link below). Will galaxy honor warranty if the tim has been replaced with better stuff (see galaxy link below)? Anyone have experience with galaxy's rma department?
