    This CPU is absolutely amazing. I got lucky with my chip and managed a good low temperature with reasonable voltage at 5.2GHz.

    Bought this CPU weeks before Comet Lake processors were launched. Best Buy kept tempting me with price drops and after one particular drop to $450 that I missed, I told myself I would click the purchase button the next time it happens. True enough, that happened and I'm left with a box that took me longer to open than it took me to install the CPU into the motherboard socket.

    I couldn't say if I won the silicon lottery because I understand that the fab actually improves both midrange (typical) and tails (slow/ fast) over time. As this is really +++++++ by now, I guess a lot of secret sauce has gone in to this chip. 5.0GHz all cores are 1.3V or less. AVX tortures still pushes this beast to draw 249W on my system. It took my custom loop to the brink at 85C under those conditions. The loop isn't ideal (parallel blocks, partially blocked exhaust, slim rads) so I think it's still ok.

    Don't really run CPU intensive workload nowadays. Just feeling great knowing I have the top chip in the 9th Gen (other than 9900KS) in the rig.

    This processor is Incredibly fast, it handles an all core 5ghz overclock with no problem. I guess I won the silicon lottery because mine only gets to about 70c with synthetic benchmarks, during real world usage and with a 240mm AIO water cooler it only gets to about 40c - 50c.

    Not really the best "bang for your buck" kinda CPU but it is supposedly the best one for gaming. Works wonderfully so far. Temps are quite good under load, but then again, my ambient room temperature is fairly low and I have a 360mm rad cooling it.

    Awesome 8 Cores and 5.0GHz or more.

    Get's pretty hot after 5ghz haven't had it run above 61c yet on 5ghz after a 5 hour stress test.

    Probably not the best bang for buck CPU available, but single thread performance is awesome.

    also runs extremely hot, AIO coolers cannot handle this cpu with an overclock, and some CPU waterblocks cannot disperse the heat generated by this fast enough.... cooling is difficult.

    Fast and runs at 5.0Ghz @1.26v. I keep it at stock though because all the excess heat outweighs the very slight performance improvement.

    "I bought this CPU only for the box."

    Unless you have a weird obsession with the box like me or you need the higher processing power, get a 9600K/9700K or a Ryzen 7 2700X instead and save the difference. Better yet, wait until Ryzen gets Zen 2 if you are patient enough.

    As for overclocking, I cannot speak to its capabilities having lost the silicon lottery. You should have something better than a 240mm AIO to push this processor beyond stock.

    Just about anything I could say about the i9 9900K has already been said a million times. It's an absolute beast in just about all applications.
