    I7 9700k delidded with rockitcool copper IHS and liquid metal as usual on these. I'm working 80 hour weeks now and only have time to test 4.9Ghz AVX in OCCT linpack to make sure temps are good and the IHS seated properly.

    $270 shipped

    Pics of the delids and relids of a Rockitcool copper IHS. Quicksilver was used for removal of the factory STIM solder, not sandpaper or razor. Super clean and used Thermal Grizzly Conductonaut liquid metal and a very thin layer of Permatex automotive gasket maker to attach the new copper IHS (the camera made the layer look thicker than it actually is).
    I have various I9 9900Ks, I7 9700K/8700K, and i5s all of which got the same treatment.


    Used a Gigabyte Aorus Elite Z390 motherboard for testing. With a 240/280mm AIO and 1.35v limit (maybe 0.02v more if temps are really good, but will be noted if so).
    Please understand this board has an excellent VRM setup, and other boards with different VRMs and LLC controls may need different voltages, and may not be stable at what I get stable. If you have a Gigabyte Aorus Z390 you should expect similar results with similar settings.


    Listings are for the CPU only no cooler or box with the copper IHS already attached and ready to go.


    iPad Pro 11 64Gb, was a Sprint data one but the bill isn't being paid and is now functionally a WiFi model. Has the apple folio case and apple pencil. It's in like new condition with pics below.
    $640 shipped with pencil and folio SOLD



    I was in the middle of testing this 9900K when my board flaked on me. The main bios is corrupted and the backup bios will only boot windows with default settings for some reason. I did get a 5Ghz cinebench test completed before this happened. To test avx stability and temps I could only use default settings though. But OCCT linpack at stock 4.7 all core load with AVX (which is more demanding than prime 95 I am noticing) was loading around 1.15-1.2v and temps were really good. I just can't promise any high overclocks without being able to test it further. Below are temps and tests that I did do.

    Rockitcool copper IHS and liquid metal as usual on this.

    $430 shipped SOLD to inglewood78


    Intel i7 8700k with rockitcool 1151 8th gen copper IHS and liquid metal. 5.1Ghz AVX stable, low 70s for non AVX load (cinebench) and high 80s to 91C hottest core for Prime95AVX load at 1.36Vcore (AVX LLC results in 1.38V)
    $320 Shipped SOLD to chuckd007


    Intel I7 9700K delidded with rockitcool 1151 9th gen copper IHS. Only had time to test to 5Ghz AVX stable with 1.35v. Will do further testing this weekend.
    $320 shipped. SOLD



    Intel i7 9700K delidded with rockitcool 1151 9th gen copper IHS. 5.1Ghz non AVX stable, 5Ghz AVX stable.
    SOLD for $365 shipped to hazmatic

    Intel I5 9600k delidded with rockitcool 1151 9th gen copper IHS. 5ghz non AVX, 4.9ghz AVX stable like the majority of the i5s I've had and seen.


    1TB Samsung 970 Evo Plus NVME M.2 SSD. New sealed in box. Got it in a trade and wanted to keep it, but need to sell it to have money for more CPUs.

    Sold both for $420 to tnt3k


    Intel i9 9900K Delidded with a Rockitcool 1151 9th gen copper IHS. This was one that really needed a delid. Stock IHS would hit 99C and throttle in Cinebench at 5Ghz. Now its stable at 5.2Ghz with a core spread of 75-84C, and is Prime95AVX stable at 5.2Ghz as well. Might be able to bring temps down more too, haven't tested lowest stable voltage yet and was using 1.37V.
    Traded to deruberhanyok


    Intel i5 9600k Delidded with a rockitcool 1151 9th gen copper IHS attached. 4.8Ghz AVX stable, 4.9 non AVX (maybe 5).
    SOLD to chukcd007 for $225 shipped

    Intel i5 9600K Delidded with a rockitcool 1151 9th gen copper IHS attached. 5Ghz AVX stable. First one of these I've seen be 5Ghz stable with AVX. 1.35V and 83C hottest core temp.
    SOLD to Schmittmj for$260 shipped

    Intel i5 9600K . Delidded with a rockitcool 1151 9th gen copper IHS attached. It seems like a 4.9AVX /5ghz non avx chip, but still in testing.
    SOLD to chuckd007 for $225 shipped


    Intel i5 9600K . Delidded with a rockitcool 1151 copper IHS attached. It is not a super high clocker, but it would make a good CPU for a budget gaming build with air cooling in a lower end Z370/Z390 board that doesn't have a strong VRM. 4.9Ghz 1.35V stable with Prime 26.6 and 4.8Ghz AVX stable with 1.34V (probably could do less but haven't tested lowest voltage). AVX temp range 72C-77C, non AVX range 59C-64C.
    SOLD to deruberhanyok for $225


    EVGA GTX 1070 TI SC black edition ACX 3.0
    Card only, got it in a trade. Clean and like new.
    SOLD to dodgerpro for $280 shipped


    Intel i5 9600K . Delidded with a rockitcool 1151 copper IHS attached. It is not a super high clocker, but it is very cool at 5Ghz and would make a great CPU for a good quiet air cooler. 1.35v 5Ghz Prime95 26.6 60C-64C temp range, 4.9GHz Prime95AVX 66C-72C range. 5Ghz with up to 1.38v failed prime95AVX, but is fine with prime95 26.6.
    SOLD to superjoe for $240 shipped


    i9 9900K does 5.2Ghz Prime95 AVX and Prime95 26.6 stable. 5.3Ghz is close, Im guessing around 1.37-1.38 would do it. Temp range in Prime AVX was 66-77C. Before delid was 76-91C. De8aur sells 9900Ks delided that do 5.1Ghz for over $1,000. Listing mine for,
    SOLD to Promleminfected for $565


    i9 9900K does 5.1Ghz Prime95 AVX and Prime95 26.6 stable. 5.2Ghz was close with 1.35 but not stable. Temp range 68-75C.
    SOLD in a trade to thelead


    i7 9700K does 5Ghz Prime95 26.6 stable. First core fails on Prime95 AVX after ten minutes or so at 5Ghz, but is fully AVX stable at 4.9Ghz. So you can set the AVX option in the BIOS to drop 1-2x under AVX load, or add more voltage, up to you. 4.9Ghz PrimeAVX load temp spread was 77-87C, before delid was 81-91C. 5Ghz Prime95 26.6 was 72-77C
    SOLD to chuckd007 for $330

    For trades, will consider a Gigabyte Z390 Aorus Elite or better motherboard, or high end VRM Z370. My Corsair K95 cherry red keyboard is having its LEDs die, so might be looking for a newer Corsair RGB replacement. A 500GB-1TB NVME SSD is also on my list.

    Doesn't Conductonaut do bad things to bare copper over time?

    It will stain copper, but it won't impact performance. Aluminum however...

    It's fully safe for copper.

    Added one of the 9900ks

    I wish you were selling this back when I bought my 9900k. I definitely would have bit.

    Adding second 9900k shortly. With 1.35v 5.2 didn't work, but 5.1Ghz seems ok so far.

    The Rockitcool copper IHS's I have seen are supposedly not compatible with the 9900K because the die is slightly thicker and as a result will put too much stress on the 9900K die vs the others of the same gen. Did you modify the Rockitcool? Or did they release a model to account for the die variance?

    They released a new model for the 9 series. That is what I used.
    There is roughly half a mill or less of space from the PCB and the edge of the IHS to allow the rtv gasket to not raise the IHS off of the die when a thin layer is used.

    Would really like to have a couple of these sold by Thursday so I can avoid a fee on something I have to pay. Make me a reasonable offer.
