Can you get other stat like CPU fan %, case fan % 1 & 2?

    Hi,

    How can you get other stat like CPU fan %, case fan % 1 & 2?

    Thanks

    Afterburner doesn't provide access to such sensors, but you can use plugins to pull the info from 3rd party monitoring software such as HWInfo:

    AB settings
    -> Monitoring tab
    -> "..." (three dots) button next to the "Active hardware monitoring graphs"

    HwInfo only give MB temp and CPU fan rpm, still can get % of fan CPU, case 1 and 2?

    You can customize which sensors HWInfo exports to RTSS thru HWInfo settings (the "cog" icon in the botton right), in the "OSD (RTSS)" tab.

    If fan RPMs are available, the naming will vary by motherboard vendor and model, and fan numbers will not necessarily be consistent across BIOS/MB vendor's software/3rd party software.

    E.g. my Gigabyte Z97X-Gaming 3 has fans "CPU", "System 1", "System 2" and "System 3" (plus another that's not visible - perhaps because no fan is connected to it).

    If you use multiple fan connectors on the motharboard, you'll probably need to go thru them one by one, change the speed, and then note which fan that connector controls. (Again, having it labeled "Fan 1" on the motherboard and its manual doesn't mean 3rd party software will have it as #1.)

    *

    Since the value returned will be RPM, to get percentage you need to find out what each fan's maximum RPM is, then add a correction formula to convert RPM -> % in Afterburner settings.

    At least Gigabyte's (bloatware) system tool allows you to "calibrate" the fans - it runs them on speeds 0 - 100% with 10% point steps, and reports what RPM each % corresponds to.

    Once you know what RPM you get from 100% (for example 1242 RPM), you create a correction formula: "x/12.42" (which comes from 100 * x / 1242).

    The downside is that you don't get back the PWM % the fan is running at, since fan curves are not guaranteed to be linear.
