Any one else do yearly clean up of their PC?

When i say clean up i am talking 120 lb air presser to blow the dust out of it.

My gaming computer gets full of cat hair and cigar smoke fast due to the case design and all the fans i have going.
Last night i was playing Fallout 4 for a few hrs and the game locked up, so i started diagnosing the problem and saw my CPU cores were at 72c and video was at 82c.
The CPU was doing that speed steeping or what ever its called to save its self from frying.
Good thing i had a mild OC and did not disable all the features like i used to when it was under water.
30 minutes with a air compresses and i am back to 55c under full load on the the CPU and 70c on the GPU.

With all the cat hair and cigar smoke i blew out of the case i could have rolled a box of cigars and built a new cat.
One of my cats likes to sit next to the 230 mm side intake fan for some reason and just looks at the lights flashing behind the fan.
I guess i know why now, it pulls all the lose cat hair off her and sucks it in to the fans.
