Ok.. Be me:
* I have an Asus ROG Strix z370-f / i7-8700k / Corsair H115i 280mm AIO...working fine.
* Upgrade to i9-9900ks. Immediately hit 100 degrees whenever my computer does anything. Latest BIOS etc etc
* Buy Thermaltake Floe DX 360mm RAD.. It blows up (power cable melts into fan controller that is supplied). No dramas. Return to shop (RMA)
* Buy Asus ROG Strix z390-e thinking the interwebs might be right.. But alas, still have heat issues..
(AVX to 5, turn off boosting, set ratio to 42. Manage heat but now we're getting down to i7-8700k levels.)
* Return i9-9900ks (RMA)
* In the meantime, buy i9-9900kf. Buy new platinum 750w powersupply to boot.
* STILL HEAT PROBLEMS.
* Tried disabling MCE, no dice.
Please.. Someone.. Anyone.. Help me.
