I am currently trying to figure out why my two 6750 graphics cards that are not even a year old fans broke.

When I tried to take the fans off to replace myself, the screws will not come out.

When I switched those two cards out, I put in an old card from my old system and now it is running hot and has already crashed once due to excessive heat. The fan also displays "tension" when rotating and has made noise when system boots up or launches a game.

I've been looking at replacement heat sinks on new egg to replace but I would like some feed back on some good ones. I'm thinking of going to water cooled instead of fan based.

Past 2 years I've gone through about 6 cards

Probably a problem with the PSU or the motherboard. The card gets too high voltages, that's why it runs hot and the fan runs too fast.

holy crap 6 broken cards in two years? You need to take a look at the rest of your system, thats rediculous. Something is getting improper voltages or something.

Agreed, and my past experience with a ThermalTake TR2 PSU is that the 12v line dips well below 12v before it dies.

That was on a system I built myself. I think it was a combo of cheaper cards and build up of dust coupled with cheap fans on the cards. I've never had any other problems with that system.

They system I'm currently running was bought straight from IBUYPOWER, pre-made ( i wanted warrenties and such this time around). The fans both broke on that but I think it was due to me constantly running the fans at 80% to keep the system cool and they just couldn't handle that kind of load.

 

I cleaned the card off and the filter to my liquid cooled CPU air intake and it was running fine only 65 degree celcius for about 6 hours with a full load ( Playing Rift). Now it's sitting at  80C just typing this.

They're supposed to bear running at 100% 24 hours a day at least for the warranty period. Believe us, there's something wrong there.

I believe you guys completely and really apperciate the input but I'm still stuck on any advice on how to go about fixing the problem or even where to start at addressing the issues ya'll have pointed out.

Well, if you have money, replace the motherboard and the PSU. If you want to tinker a bit, get a multimeter and measure the PCIe voltage as well.
