Gpu overheating bc fan resistance

post #1 of 4
Thread Starter 
First off I'm somewhat of a noob with computers. I know the basics in hardware and how to build a computer, but beyond that I'm lost so please bare with me.

I bought a new computer with two radeon 6870s crossfired at the end of October and everything was perfect up until a week ago. All of a sudden BF3 would drop its usually consistent 60 fps to a consistent 30 fps after about 30-40 mins of playing. So first thing I checked was the temperature and sure enough the primary card was hitting 117c while the other was at the usual 62c. So I thought dust was the problem. I took out both cards to dust them, but both were completely dust free. However, while dusting with air I noticed that one gpc fan spun freely while the other didn't spin at all with the air. So I tried spinning each with my finger and one spun like butter while the overheating gpu could spin, but had a lot of resistance. I put everything back and watched the bad fan. It would spin then stop, spin/stop over and over again.

I'm really afraid of taking my graphics card apart because I feel I might create even worst problems. What would be the best/easiest thing to do? Could I just oil the fans bearings? Or do I need to replace the whole fan? Thanks for any replies.

3 options;

 

1. RMA.

 

2. Third party cooler http://www.arctic.ac/en/p/detail/index/sArticle/502/sCategory/2182

 

3. Oil the fan.

Thanks for the reply. To oil the fan would I have to completely remove the fan from the gpu? If so I'll just go ahead and get a third party cooler since that would be close to the same amount of work. I would rather do the oil, however,if I can just remove part of the fan, add the oil, and be done with it. It would be even better if I could add oil without taking anything apart. Sorry for the noob questions. I'm just new to this.
