    Since I switched over to a spare EVGA CLC 280 I've had since last year during a new (new defined as pulling down all the stray EVGA components I have on my shelves) EVGA heavy buildout, my 9900k p0 is running amazingly cool and I've been able to push my 9900k to 5.2 all cores and running the adaptive run I did last year where CPU thermal throttling to 100 quickly would reduce clocks on a Realbench 2.56 run I can now run it full adaptive 1.388 pull under load and top out at 89-90.

    Problem is my VRMs are overheating now which was never a problem before on the EVGA Z390 FTW since CPU thermal throttling would beat it to the punch quickly. HWinfo shows VRMs are hitting ~96 and then they throttle back to 92-93....get back to 96....rinse repeat clocks as expected drop to ~3.6ghz then shoot back up to 5.2 when the temps drop. CPU temps are holding steady at 87-90. Short runs on CB15 and CB20 are no problem since the VRMs don't get a chance to overheat.

    This might be a combination of switching from the extra air flow of the NH-D15 over the VRMs in unison with the new steady 5.2 clocks along with this being a refurbished Z390 sent to replace my defective Z390. Or it could just be worse/failing VRMs.

    CPU actually pulls less with RB 2.56 (~188w) vs CB20 (~220w) @ 5.2 adaptive.

    I never logged my VRM temps on my original board since it was never a problem before CPU thermals ran amuck.

    Yeah my performance right now with my (2) slim EKWB 360 rads is pretty darn amazing. My 2080Ti running a steady 2,130Mhz gets no hotter than 38C max at 1.093MV W/ 380 watt Galax bios and 8 ohm shunts stacked and soldered. I am running push/pull on both 360 radiators. I was originally going to run quieter fans, but I decided against it. The only thing that's really loud is my cheap water pump. "It rattles and vibrates like crazy" this is what pushed me to invest some money in to a good pump.

    I was thinking maybe 3-5C. And that would be perfect honestly! I am trying to keep my 2080Ti under 36C, because then I can manage higher frequencies in games. It is amazing what my GPU can do when it runs 35-36C. But once it gets above that, its like stability kinda goes out the window. And then I have to resort to 2,130.

    It may seem silly, but chasing these tiny numbers is so much fun haha.

    I saw also a bit lower Cpu temp while the Cpu run idle with all thermal mods, max fans with fan+1 and my modded U3. Both CCC and Core temp showed the same temps. So there is some truth in this even though it sounds unlikely:)

    I thought this was pretty funny so I decided to share.

    I was looking at Silicon lottery binning statistics on a 7980XE and I wanted to test my CPU.

    My 7980XE is delidded, lapped, and on a custom loop with (2) 360MM radiators. So
    my temperatures are really good. I wanted to see how it does compared to their results.

    Here is silicon lotteries results.

    7980XE 4.10GHz 3.80GHz 3.60GHz 1.075V 100%
    7980XE 4.20GHz 3.90GHz 3.70GHz 1.087V Top 89%
    7980XE 4.30GHz 4.00GHz 3.80GHz 1.100V Top 72%
    7980XE 4.40GHz 4.10GHz 3.90GHz 1.112V Top 35%
    7980XE 4.50GHz 4.20GHz 4.00GHz 1.125V Top 8%
    7980XE 4.60GHz 4.30GHz 4.10GHz 1.137V Top 2%

    I always thought my CPU was good because it could pass realbench with NO AVX offset for however long at 4.6Ghz with 1.203V. Or 4.8Ghz at 1.280V is also stable.

    But, apparently it is just average..

    I failed the top 2% 4.6@1.137V

    I failed the top 8% 4.5@1.125V

    I failed the top 35% 4.5@1.112V

    No further testing has been done. It doesn’t bother me, I just always thought my CPU was good. But apparently it’s just mediocre average!

    My cpu still runs 4.6Ghz 100% stable as low as 1.181V I just tested again today. That’s the best I could manage at a stable 4,600Mhz. It has been like this since I have owned it. So no degradation or anything.

    So I went ahead and installed the new pump. I couldn’t quite get my 3rd rad in today. Because the company I bought from decided not to put my tubing and fittings in the shipping box. So I had to get my system together asap. Can’t wait unfortunately.


    Anyways. I love the new pump!

    I will say this, it’s absolutely worth watercooling a 2080Ti, if you have a 2080Ti! You can squeeze a solid 30% performance VS a stock 2080Ti numbers in these reviews that they compare against 3080’s and 3070’s. Which is just so silly.


    Yep let’s go another 2 years!

    Oh and a D5 on full speed is literally silent! And it flows just tons and tons and tons of water!

    Very nice build bro. Where are you going to put the third 360 rad in that case?
