I'm building a PC for my sibling and plan to reuse some parts from their current setup to save money. I realized that their i7-9700 processor is 9th gen, while the motherboard I've picked (an Asus ROG Strix Z690-E with LGA-1700 socket) is meant for 12th gen CPUs. I haven't seen the processor yet since my sibling is still using the computer. Can anyone confirm whether the i7-9700 will fit in the motherboard socket, or should I look for a different one?

Unfortunately, the i7-9700 is designed for the LGA1151 socket, while your Z690 motherboard requires an LGA1700 socket, so they aren’t compatible.

Damn, that sucks. But at least I'll be able to return the board and get a different one that does fit. Any recommendations if you got any?
