I've got the 14700k with MSI MAG Z790 TOMAHAWK DDR5 with the MAG CORELIQUID 360R V2 paired with an RTX 4070 TI GAMING X TRIO. CPU runs crazy hot (70 to 80 with Cyberpunk 2077).

خرید مادبرد های ریفربیشد سری Z790 EDGE با توجه به بالارده بودن مادبرد ارزش داره؟

Short answer is no. You'd risk a lot by buying a refurbished MB including bent cpu socket pins, debris in the RAM and PCIE slots, and damaged power delivery to the cpu. Given how hot and power hungry intel CPUs have become recently, I'd strongly recommend buying factory new MB.
