Ok, so I have a gigabyte gtx 950 and a few days ago I've started to notice, that after approx. half an hour of gameplay a fan gives some funny noise, not sure it's the gpu, so I've removed it, done some dusting, and now it gives some different noise, and this time it's definitely the gpu, but only one of the fans. idk how to describe it, it's probably not as smooth as the other one. Is this a problem? Also I've got three bsods this week two of them while playing gta v with the message: UNEXPECTED_STORE_EXCEPTION, and one while playing swtor, MEMORY_MANAGEMENT. And yes I have tested my memory with memtest86, and I have updated my display driver. Whats the problem? And btw these are the only bsods I've ever got. Any help is appreciated. Thanks in advance.
