You probably dont need to sacrifice performance to get lower temperatures. Stick with stock speed and lower the voltage instead and go from there.

Intel Core i9-9900k (Silicon Lottery 5.1GHz @ 5.3GHz 1.36 VCore)
ASUS ROG MAXIMUS XI APEX
G.SKILL F4-4000C19D-32GTZSW (2x16GiB 4000MHz 19-19-19-39 2T, tuned to 4133MHz 14-17-17-31 2T)
EVGA NVIDIA GeForce GTX 1080 Ti FTW3
Seasonic PRIME 1300W 80+ Platinum

What do you think the lowest voltage I can get away with is, if I'm only going to run the CPU at 1.6ghz? It says on the intel site that 0.85v-1.5 is the voltage range for this. Does that mean the CPU can be run at 0.85v, if you are only using 1.6ghz?

I lowered the voltage to only 1.00v and it seems to be stable so far with prime95 running, and the temps never get above 55c
as a former Q6600 owner that is a problem even at stock (as you found out).

from my experience; with the "appropriate" stock heatsink, which had a copper core, it would run warm. any OCing would see 50c tamps at idle and 80+ under any load. i can't imagine using an all aluminum heatsink on that.

you will have problems until you get a better cooling solution.

Remember the golden rule of statistics: A personal sample size of one is a sufficient basis upon which to draw universal conclusions.
