hello! can i install intel core i7 4790K processor from Imac 5K as i know all components in new imac is the same?!(not consider logic board and LCD) by the way, TDP core i7 4790K is 88W. but heatsink is the same? so, it can be done? Update its not a problem for me. a have all need tool and skils to open imac. i’m not shure that 4790K is started in old logic board.
First here is the specs of your iMac’s series: iMac14,2. Here are the CPU choices: 3.2 GHz i5 (i5-4570)3.4 GHz i5 (i5-4670)3.5 GHz i7 (i5-4771) As a reference heres the i5-4670 chips specs on Intel’s ARC site: i5-4670 Processor and here is the i7-4790K Processor. Note the socket supported: FCLGA1150, so it appears to be physically possible. The only difference is the TDP 84 vs 88 Watts. Even still the systems firmware may not allow you to make the change. Keep in mind this would be a very large undertaking! You’re a trailblazer here I don’t know of anyone going that far. Are you sure you want to take the risks here? Also the ‘Thin Series’ iMacs are harder to open and you do need the correct tools as you can easily damage the display if you are not careful.
