I'm hoping someone out there can help me. I have a 13700k on a Z790-E gaming mobo.
Everything is completely air cooled (nh-d15 chromax along with 3 X 140 noctua case fans).
I have my fan curves dialed in the way I want but once in a while when gaming a couple cores will ramp up to 70c or so for a few seconds making my fans spin up / down quickly.
Someone has suggested to me to head into bios and setup my CPU / Case fans step up and down speeds.
But there is literally 0 documentation explaining how it works or what these "levels" equal too.
The bios manual only states:
CPU Fan Step Up
Step up allows you to adjust how quickly the fan rotation speed increases, with level 0
being an instantaneous change in speed. The higher the level, the slower the change
in speed, and may also result in less noise, but this will also cause slower heat dissipation.
Configuration options: [Level 0] [Level 1] [Level 2] [Level 3] [Level 4] [Level 5]
What does each level equal too in seconds?
Do the seconds mean time between ramping from 0% fan speed to the programmed destination speed?
Should I set ramp up and ramp down time to the same level?
Any help at all is greatly appreciated!
Level 0 is almost instantaneous, level 5 is the slowest. For more gradual less intrusive ramp times, you want a higher level. I'm unsure what this equates to in seconds, but once you've optimised the fans what is stopping you from experiementing with each level? Noise levels are subjective, after all.
Yeah, I just found it really odd that the official documentation would label something level 1,2,3, etc with no context at all if it's seconds, percentage based or something else.
I'm testing them right now at level 3 and only picked it because it was the middle option.
