Extreme speeds causing fans to stop and restart on initial program load until program is closed and re-opened #2676

Open AndrewCathcart opened 3 weeks ago

AndrewCathcart commented 3 weeks ago

Describe the bug I'm not really sure how to describe this - I don't know if it's an issue with my fans, or FanControl, but sometimes it seems to be spinning my Top / Rear exhaust fans up to an extremely high speed causing them to rattle and then stop spinning, and then cycle doing this until I close and re-open FanControl.

This has only recently started happening, I'd say in the last 1 month. I've been using Fan Control since early January this year with the same specs.

This is my current config; https://i.imgur.com/jXUeAGB.png

It seems to happen most often from a cold boot into launching a game.

I've tried recalibrating the fans, and I've also tried setting all of the fans manually to 100% speed for about 15 minutes just to check that there's nothing mechanically wrong.

Is there a log.txt file next to FanControl.exe with recent date entries? [Link it here] log.txt

Relevant hardware specs and setup [Laptops and most proprietary pre-built desktops are not supported.]

Not entirely sure what's relevant but; ARCTIC P14 PWM PST A-RGB x2 (Bottom Intake) ARCTIC P12 PWM PST A-RGB x3 (Top / Rear Exhaust) MSI GeForce RTX 4090 SUPRIM Liquid X 24G AMD Ryzen 7 7800X3D DeepCool LT720 B650 AORUS Elite AX

Please let me know if there's any other information that might be worth posting.

When said cycle occurs, does it show in FanControl? Like is it your config driving that behavior? Do you have any hysteresis/response time on your curves to avoid temperature spikes?

AndrewCathcart commented 3 weeks ago

I'll keep an eye out next time it happens - I don't think I can see anything specific though, FanControl thinks that the fans are at 100% even when they've spun down.

It's almost like the fans are spinning too fast? It only resolves itself if I restart my PC, or if I restart FanControl. I've tried manually tinkering with the speeds by switching to manual and when I manually set the fan speeds to 100% it seems like the problem is still there.

Could it be that FanControl thinks the fans can spin faster than they actually can, and when I restart the program it gets the correct values again? Something like that?

I've attached my actual curves for CPU and GPU with hysteresis config. Do note though that I don't think it's hysteresis or anything that's causing the fans to spin down - they literally span as fast as they can (making some awful noises) and then they seem to power down, and then try to spin as fast as they can again. Like they're receiving too much power or something (sorry, my vocab here is a bit limited, hope you know what I mean).

That small hysteresis/response time won't prevent up/downs if your temperatures start moving a lot. You should probably increase both the temp and time to like 5-7C, 5 sec +

AndrewCathcart commented 3 weeks ago

I'll do that now.

edit: done

Still having issues when booting. If the rear fans get anywhere close to 95-100% speed, then they're making a horrendous noise / wobbling. Seems to always resolve when I close and restart FanControl, even if I manually set the speed to 100% after restarting and they're running at 1850RPM. Any recommendations? Have you heard of this happening before?

Have you heard of this happening before?

No I have not. From the software's perspective, there isn't much. In the end it sends a 12V signal or a 100% duty cycle signal. It can't "overshoot". So if going full speed your fans start shaking/acting, maybe it's a mounting/orientation issue, or a defect. Hard to say.
