It might work fine with the current setup, but you could wait for a more suitable MOBO before using it fully.

Requested a 9900K upgrade from an i5-8400, expecting it won't support overclocking on the existing board and possibly throttling because of VRM overheating. Concerned about potential impact on CPU or board longevity, especially regarding heat effects. Current board details provided.
I need to understand your interest in purchasing a 9900K. If you can secure it for under $250, it might seem reasonable, but after adding an upgraded motherboard, the cost-benefit and ease-of-use points weaken. Wouldn't it be wiser to opt for a 12400F paired with an MSI Pro B660M-A board? That setup only costs around $325, and the i5-12400 delivers superior performance across most scenarios—just slightly slower in certain multi-core tasks but noticeably faster in single-core work. The 12400 is simply more efficient overall. An overclock could help the 9900K narrow the gap, though it would mean replacing the board entirely, which undermines any advantage.
The older i9 model is actually inferior to the new i5 models using the b660 board. Intel largely eliminated demand for the used market with the discontinuation of the 12100f and 12400f chips if prices stay the same. I've noticed more interest in the 9900K series than the 12600KF on sale.
I agree with the others. The 9900k remains strong, but only if you already possess it or can obtain it at a low cost.
Sure, I’ll opt for an i5 instead. Thanks for the help—I didn’t think it offered better performance since I usually ignore newer parts because I thought they were costly.
Older models, particularly premium Intel components, usually rise in price over time. It's generally more economical to opt for the latest mid-range options that still perform well. On eBay, the i9-9900K ranges from $300 to $400. Amazon offers a similar 9900KF model around $520. In contrast, an i7-12700F is available for $312 and delivers superior performance. You can also find a 5700X for just $299, which also excels in all aspects.
For four hundred dollars it makes sense. You might find a 12400F with a solid B660 board for less (around three twenty-five), but if you aim for modern overclocking, a 12600K and Z690 would be pricier than four hundred. The 12600K with Prime Z690-P is near five hundred. Also, the Maximus XI Hero offers top features, giving you more benefits. It's not that the 9900K is bad if you already own one; it just isn't worth it for a new buy in 2022 since it runs about as fast as the 12400F—about three eighty dollars—and Z370/Z390 boards are also costly. You managed to get a good deal, so that's acceptable, but outside this range, the 9900K isn't recommended unless you're just playing.
