I keep this cooled with a Noctua NH-D15S Air Cooler. I'm idling at around 35 Degrees. Under gaming loads (with an RTX 2070) it's usually between 55 and 65 degrees. Most people say you should liquid cool this only, I don't agree.
Shiny packaging, Handled Adobe very well for a day.
Failed after a day, on safe bios settings (No overclocking).
WHEA Uncorrectible Error when trying to install Windows 10.
I've build PC's for years, and I'm a workstation user; not a gamer or overclocker. I set them up to run cool, and stable for a long time.
I Built this system, monitored all the temps, Loaded Windows 10 to my M.2 drive, and I was up and running, and started editing videos to see what it could do.
By the end of Day 1, the system started randomly crashing during video editing. Went into the bios, checked the temps/voltages, everything ok... Stable temps, stable voltages.
So, I started looking at drivers. Didn't see any issues there, but Windows would randomly crash even when using basic functions. Right click Computer, Bam! reboot.
Formatted the drive to re-install Windows 10, and that's when I started getting the WHEA Uncorrectible error. Windows installer would crash at about 2-3% of installation. I tried USB and DVD installers based on the Microsoft media creation tool. I tried my old trusty Win7 install disc too.
Ram check ran, didn't find any issues. Scandisk, good there too.
Swapped HDD's. UEFI vs Legacy, Tried just about every combination I could, in addition to different ram.
When we swapped out the CPU for an older I7-8700, the system booted, installed windows, and didn't crash using all of my existing hardware.
Swapped the I9-9900K CPU back in - WHEA problem returned instantly.
