Started purchasing parts for this build in January. The prices I entered are what I paid for the components (before taxes, shipping etc.) Most deals I found online then matched at Microcenter, or found on open-box discount.
Overclocked to 5.25 Ghz (-1 AVX offset), stable @1.38v, temps in mid-high 70s under stress test, under 60c during game.
Amazing chip! Got mine to overclock to 5.25ghz on all cores (-1 AVX offset). Stable @ 1.38v (tested with Prime95, RealBench, and actual streaming/gaming) with temps in the mid to high 70s at load and staying under 70c while streaming/gaming (cooled with a 360mm AiO).
Great AiO cooler. Keeps my i7-9700k temps in the mid to high 70s during a RealBench stress test with all cores overclocked to 5.25ghz (-1 AVX offset). I installed Corsair ML120 fans instead of the stock fans for aesthetics. Mounted them in a push configuration at the front of the case (Phanteks P600S) as intake.
Installation is easy if you do it while the motherboard is flat. You'll need to hold the back plate while you get the first two screws in if you install it vertically while your motherboard is mounted in the case.
The pump is audible under load if you don't have a lot of other ambient noise from fans and if you have your case open. With my case closed at idle temps I can barely hear it.
The accompanying software, Corsair Link, is not the worst around. It lets you set the pump and fan modes between extreme, balanced, quiet, and zero-rpm and if you have other corsair components that are recognized (Corsair RGB Memory, Lightning Node Pro etc.) you can sync them all with the same lighting profile. One confusing aspect is the temp displayed is not the actual CPU temp (might be liquid temp or something) but don't use that value as any kind of indication of accurate CPU core temps when stress testing.
You can also opt to not install the Corsair Link software at all and just set the AiO pump speed on the respective motherboard header using a fan curve/profile, which is what I ended up doing after I got tired of background services clogging up my system tray (Aura, Link etc.) If you just want it light up and work, you can simply just plug it into the CPU/AiO header and USB connector, then set your fan curve in your BIOS and forget about it (once you confirm your desired fan profile is working).
Solid Z390 board, performs and looks good (even in a black case). ASUS UEFI BIOS has a ton of options for overclocking and power management. The adaptive mode voltage and LLC work great together on this board to keep my i7-9700k stable at 5.25ghz ~1.38 volts. Bus clock was able to go all the way up to ~215. XMP works great on multiple ram kits, I've tried Corsair and G.Skill so far no issues. Managed to overclock Corsair Vengeance RGB 3000CL15 kit to ~3740 Mhz at 16-21-21-36 timing. 1.45 volts (tested for 2+ hours with MemTest64). FYI one thing to note for RAM overclockers--there is only one input value for tRCD and tRP, so you can only modify them both together.
Solid DDR4 kit with RGB lighting. Overclocked to 3200Mhz out of the box, no changes to XMP timings. Managed to get this kit to run at ~3740Mhz with 16-21-21-36 timings at 1.45 volts, however I am currently just running them at 3200CL15.
LEDS are little bright. Light Enhancement kit is available for a reasonable price, which is convenient for those who want the aesthetic but don't need 32GB of DRAM.
Depending on the card, the fans can be a little noisy at higher RPM but the card stays relatively cool so it shouldn't need to ramp them up very high under load with decent case airflow. Mine stays under 60c. Card also looks great with the ROG backplate and LEDs. Works with ASUS Aura sync, although it seemed to just choose display whichever lighting profile it wanted to default to if I uninstalled the Aura service.
