After finishing my first hardline custom loop I have had trouble hitting 5ghz without hitting 90+c(while running a stress test)on my cpu and Vrms. I have little experience with overclocking CPU’s and memory as with most of the pcs I’ve built I have left the bios almost untouched. I have tried messing with offset/tried to under-volt it but had no luck. I understand that the 9900k does run hot but not this hot, especially with a custom loop.
My rig
Cpu: i9 9900k
Motherboard: Msi z390 Godlike
Memory: Corsair dominator platinum 32gb 3600mhz
Gpu: Rtx 2080 ti kingpin/w hydrocopper
6 Corsair ll120 fans and an ek pe 360 mm rad
