How is SpeedFan regarding DPC latency?

    I'm looking for a way to better control my fans as BIOS is quite limited. Usually MBO suites like the ones from Asus and Gigabyte cause DPC latency spikes and related problems. Does anyone have experience with SpeedFan regarding this?

    "I'm looking for a way to better control my fans as BIOS is quite limited."

    If this is from personal experience then state the BIOS limitations you've noticed.

    "Usually MBO suites like the ones from Asus and Gigabyte cause DPC latency spikes and related problems."

    Other than ease of use, pretty graphs and eye candy, what advantages do you see these MB utilities offering? They're for reviewers (being part of the MB package) and newbies to use IMO. Most experienced users avoid them completely due to issues they often create.

    "Does anyone have experience with SpeedFan regarding this?"

    The only time I'd want to use software like SpeedFan would be in the case of a custom liquid cooling loop where both CPU and GPU temps are needed to control radiator fans. Otherwise, it would be BIOS fan control only.

    Drive mount fan controller. Real simple. Game or bench, reach over and turn up fans as needed. Too loud? turn em down.

    For someone concerned about dpc latency I believe a hardware solution would be the best :)

    Some have nifty things like multiple temp probes and whatnot as well.

    This.

    Is SpeedFan even supported anymore? It never has been able to control the fans on my Gene Z68 system...and that enthusiast board is what 3 years old now, and still no support?

    Three major ones with an Asus X79 board:
    - it has 60% as the lowest setting for case fans
    - it ramps them up and down too aggressively, making any short CPU load changes annoying
    - all the fans are controlled only by the CPU thermal sensor


    Custom fan curves and limits and custom sensor linking. I know that MBO manufacturers' utilities have various issues, that's why I'm looking for alternatives.


    I've looked into them but they're all severely limited in one way or another. Manual control is what most of them offer and that is not very practical. I like my rig to be as silent as possible, but with manual control I would have to turn the fans up no matter the actual load as I can't know the lowest needed speed at all times and have to account for intermittent max loads.

    Anyway, I got SpeedFan working and so far it's working great and shows no signs of messing with the DPC. Custom fan curves and limits, CPU and case fans are CPU temp controlled, the latter ones are also GPU temp controlled.

    I use it since it does the job really well. It doesn't cause any DPC latency issues on my system unlike the horrid tool by ASUS. Latest Speedfan beta has full support for Intel Z170. SpeedFan's GUI sucks but the backend is super robust and works really well.

    FWIW, just about all the above Asus Q-Fan BIOS control limitations have been addressed in later/latest boards except the ability to link fans with off-board sensors like the GPU.

    I know and that's a great feature. They've also fixed the fake PWM control on case fans. Unfortunately, no luck on the older boards.
