My poor old Mac mini (late 2012 2.3GHz i7) is playing up! It’s taking an age to start up, and generally being (a lot) slower than it used to be. Noticed it a few months ago when I filled up my hard drive! So I had a dig around and managed to free up around 300GB by moving to externals and deleting duplicates, and it’s getting really hot doing not a lot. So, I’ve been monitoring temps, and whilst it seems to be within limits it never reaches the 3.3GHz boost. It gets to 3.0 then hits 105 deg C the fans kick in to full tilt and core speed goes down to 2.4-2.5, I know that’s still better than base. What I was thinking was, get a dual drive kit and use command line to make a fusion drive with my 1TB spinner and a 120GB SSD and whilst I’m in at the guts, replace the TIM with thermal Grizly conductonaut liquid metal. The heat sink seems to have copper pads and heat pipes with aluminium plate and fins. Should be ok to use the liquid metal if I paint a layer of insulator (clear nail polish or laqer) over the aluminium plate and keep the LM on the die. I’d love to go full SSD but can’t justify spending around £400 on one for a 6 year old Mac mini. Hopefully there’s a new one soon. I’d like thoughts on this plan? Has anyone else done similar?
