I've recently noticed that when playing some pretty graphically intensive games I get FPS drops as my GPU temperature hits 101°C. When it hits this temperature the game I'm playing starts to lag, stutter and act generally clunky. I've tested it thoroughly and this is always the case, initially the game runs as expected but gradually the GPU will reach 101°C and stay there (regardless of what graphic settings I'm playing at), if I tab out of the game, the GPU heat instantly drops and when I tab back in the game runs perfectly fine, but after about 60 seconds it's back up to 101°C and the game is lagging/stuttering again. I noticed this was happening with two recent games (XCOM 2 and Rainbow Six Siege) so I thought it was just down to my system perhaps being too weak or the games not being well optimized enough. However I tried playing Civilisation 5 (A game that used to run extremely well) and I noticed, using MSI Afterburner, it was also reaching 101°C and thereby lagging, which is strange as it really shouldn't and it never used to behave this way before. My fan runs at around 75 - 80% during this, I tried to increase the fan speed to 100% but couldn't and I'm not sure this would help much anyway. I assume there's some connection between my GPU hitting a high temperature and my games lagging.
I had a look inside my system last night and it's extremely dusty, I don't think its even been done in the 3 years I've had this PC which is quite silly so I'll look into doing something about that, but apart from that I don't know what could cause the sudden worse performance and high temperatures I'm getting. Perhaps my graphics card is on the verge of dying or my fan isn't working as well as it should? I'm on the latest drivers etc.

Thanks, any help or suggestions would be appreciated.
