I purchased an Xbox 360 manufactured after September 2009, which means it would have the Jasper V2 (Kronos) motherboard inside. I opened it up, cleaned off the original 13-year-old thermal paste, added copper heatsinks to the CPU and GPU, and added a 12-volt fan modification to the system. I put the shell from a 2007 Halo 3 Edition Xbox 360, and it works great, and should be working for years to come.
