    Not as hot as expected

    I was a bit worried about all the reviews, criticizing how this CPU can't keep up its boost frequencies over long periods of time due to excessive heat. Because of that, I specifically bought a Noctua NH-D15, because it's "the best air cooler, that can even measure with water cooler".

    I let the CPU work on some raytracing app I wrote long ago. The app can put 100% load consistently on all cores.
    It's been running for over 3 hours, the CPU has been clocked at 4.7 GHz (stock boost frequency for all 8 cores) this entire time without dropping even once, and the temperature is around 50-55 °C with the fans in "silent mode".

    Maybe the 9900K really does get very hot, and the NH-D15 is just that good, but judging by those temps, I could try and overclock this CPU.

    At stock frequencies, it vastly outperforms my old 6700K.
    At least I can finally play Assassin's Creed Odyssey without constant microstuttering.
    This CPU is probably not worth upgrading to for those who own the newer 7700K or 8700K, but for any who seek gaming performance, this is a pretty good CPU.

    Runs very well for gaming and rendering. Would buy it again.

    Available within one day. Overall performance is 25% better than an i7 8086k (my previous CPU). It's a little heavier than the previous generation if you're interested.

    Pro

    • A CPU ready for the future
    • A lot of power in a little space

    Contra

    • The packaging of the Tray CPU could be smaller.

    A long and detailed story Direct Grinding down the Fail/IHS.

    Good processor, not cool, whether the 2700x would get as warm at 5Ghz is up in the air. I can definitely recommend the 9900k, but if you can wait, it's best to wait until February or March. Under water with Prime 95(not test from der8auer) (4.6GHz 8 cores) 73 to 85 degrees at 204W. (Data from HWMonitor).

    I didn't delidd the processor and I didn't grind the IHS flat, don't know if the minimal curvature it has with LM as "paste" is too much. But at this price I will only try it out in 2 to 3 years.

    Packaging .... At least they could have put the prozi in a plastic tray, as they usually do. In the tray version, the Prozi lies between foam in the packaging.

    * Unfortunately I couldn't manage the wait and decapitated the Prozi :-) Mainboard was first the Aorus Z390 Master
    Here is my story of Direct Die fail to grind down the IHS.
    9900k beheaded with the Delid Die Mate 2 from Der8auer available here at Digitec ;-) .
    Loht scraped off and yes then comes the sanding....it's very tempting....and I just had to do it.
    Well slept down to the Z390 Master with the OC Frame from Der8auer installed (currently not available at Digitec).
    Well PC on and tested with 4.6Ghz....I was really not satisfied yet but again take everything apart...nope. Under Prime, no matter which test, I simply got close to 100°C.

    Well, my Aorus Z390 Master was the second one. The first one was DOA. But I was missing a lot in this Aorus Z390 Master, so I bought the Asus Maximus XI Formula. And what can I say? I can keep the 9900k stable at a lower voltage and the XMP of the G.Skill 4000MHz C17 works.

    When changing the mainboard I looked at the Prozi with the hair angle and....I had not slept flat. Ok, I had to go back to it until it was flat. Installed tested and it was even worse downclocked under Prime to 3.6Ghz and still 2 cores were at 100 degrees. Took it off and saw that the cooler was on the OC frame...too much off (the dimension of the die is 0.67mm with the depth dimension). Thought already a new Prozi must ran. Direct Die fail.

    Then I had the idea to grind down the top of the IHS and especially to grind it flat (be careful not to grind it down too much or the cooler will stick to the CPU holder). I sanded down the bottom of the IHS so that there is contact between the IHS and the die again and a little play between the PCB and the IHS. The effective copper thickness above the die has only decreased by 0.2mm.

    LM installed DIE - IHS and IHS - cooler.
    This time I used test conditions like Der8auer www.youtube.com/watch?v=Ccqid7FcjOU so that you have a comparison.
    HWMonitor 8cores, 255W, 5Ghz at 1.3V, max temp in test 78°, 79°, 82°, 84°, 91°, 91°, 94°, 95°C after 15min. Average of 86.75°C vs Der8Auer 6 core 83 degrees.
    SFF heat Test Prime 95 = max 80°C

    • Performance is top
    • Processing looks correctly done as always
    • Does what it should
    • Loht is super easy to scrape off

    Contra

    • Clear Temps(soldered not modified)
    • Tray packaging....hm
    • Price
