I use this CPU in my gaming and video editing PC and it's honestly a step up from my 13th gen PC. Intel i9 CPUs have always run hot and the Core Ultra 9 is no exception. However, unlike the 13th/14th gen CPUs, you don't need a crazy cooling setup to keep it tamed under both light and heavy load(though for the sake of longevity I would still get at least a 360mm AIO or a 420mm AIO). Even a giant tower cooler like the Noctua NH-D15 Gen 2 will keep this CPU cooled properly. I don't do any heavy OCing, but the only high temps I see are during heavy rendering or compiling shaders for games(which this CPU does VERY quickly). I've used both the Core Ultra 7 and Core Ultra 9 CPUs and unless you really need the extra amount of horse power, the Core Ultra 7 is a better value than the Core Ultra 9. Stability is also easier to achieve on this CPU thanks to it's incredible memory controller. However, you really won't realize this unless you use RAM that has a clock driver in it(Known as CUDIMM), because if you're not you will not see the speeds intel claims you can hit, and if you can hit it, gets very unstable. Installation is straightforward and the same across 1200, 1700, and 1851 sockets so there isn't much to mess up. I'll say again; you will not see the high memory speeds unless you get a CUDIMM RAM kit. Conclusion: Basically only a small step down from the previous generation, but you get so much more stability and it is way easier to cool than the previous generations. Early reviewers made it sound like you were buying an i5 processor in a i9 branding, but man is it so misleading. This CPU absolutely performs like its previous powerhouse generation. BONUS: If you already have a LGA 1700 cooler you're in luck; you can reuse it on socket 1851! the socket dimensions are identical!

This crushes anything I can throw at it. I'm amazed with how efficient it is and with a proper cooling setup, how cool it runs compared to my (very) old 7700k. I'll have to try overclocking it soon, but even at stock power, it's a beast.

Upgraded to the Intel Core Ultra 9 285K for a new desktop build and it’s been an awesome “do-everything” chip. The hybrid layout (24 cores: 8P + 16E) keeps the system feeling snappy even with a lot going on at once, and the high boost clocks (up to 5.7 GHz) make everyday work and bursty tasks feel instant. What I like: Serious throughput for demanding workloads (editing/encoding, compiling, VMs, multitasking) Unlocked if you like tuning Integrated graphics is handy for troubleshooting or a no-GPU setup What to know before buying: This is LGA1851, so it’s a new motherboard platform (not a drop-in upgrade for older sockets). Power can ramp up under heavy loads (rated 125W base / up to 250W turbo), so plan on solid cooling and airflow. Intel Many listings don’t include a cooler, double-check what’s in the box. Overall, if you’re building a high-end desktop and want top-tier all-around performance, the 285K is a beast.

This CPU is easy to like bc it’s chill. Truly lol Great stable performance without being hot enough to fry an egg. Pair it with CUDIMM 8000mt/s and a Z890 board for best results.

Excellent Processor, especially for people who do more than just game on a PC. (I do also game & it shreds 1440 resolution-2K gaming, paired with a 5070 Ti Graphics card) . I put it in a full-size computer case that has good air flow & with a $98 liquid cooler (360mm AIO ) and at load it never reaches 60C. So if you build the computer correctly, heat is not an issue. These Intel Ultras run efficient and cool if you build the computer the right way.

Every year I build a new pc based on the best components available,last year It was amd but this year i went intel,and so far it’s been interesting,this year amd components are twice as expensive,i went with the msi unify x 890 motherboard and it turned out to be defective,so i returned it and purchased an asus 890 hero motherboard which i really like,but the dvi cord was defective and i thought my 4090 graphics card was defective!!! Then my asus aio water pump didn’t work,i went with a Noctua air cooler, i wondered what the heck is going on!!! I finally got it all to work,really well i might add,i love the intel ultra 9 285 processor,im able to use G.skill cudimm 8400 ram,it works flawlessly,the pc wasn’t what i had planned but turned out to be better than I had planned,so far I’m really pleased with it,but it’s definitely the last pc I’ll ever build,should I have built another amd pc instead,not on your life!!! The intel codes didn’t work though for the free games
