I did almost all the same upgrades to my T430 around 2014, with small variations (BIOS reflash with hardware programmer instead of software workaround for wifi upgrade, as at that point no workarounds existed). I used it for more than 2 years, but I had to upgrade because I needed more RAM. It still lives with a friend. It was surprising how well the CPU behaved, especially since the thermal solution was not really created to handle 45W CPUs (there were no T430 laptops with quad core CPUs).
