6) Restart PC

Now my fans run at the desired rpm:


I still don't find this solution ideal and the fan speed still fluctuates a lot (e.g. when starting Firefox the fan speed ramped up for a few seconds and then went down to the desired rpm) but for now it's "cool and quiet" and I'm happy. Is the kind of fluctuation in fan speed normal for pwm fans? The fans sped up to 1500rpm for a few seconds when just opening a new tab in Firefox.

Should I give this fan control device a try?

PWM controlled fans will ramp up according to processor load, so when you start a browser and the CPU has to ramp up, it's normal and expected that the fans will ramp up too. Once the browser is loaded and the CPU usage drops down, the fans should drop accordingly. PWM control is a method of using variable fan speeds, so they will change... feature, not a bug!

I see that now, thanks!thumb.gif I just found it weird... maybe because I've never used PWM controlled fans before. Those speed spikes are kinda annoying though. I'd much rather have them constantly run at a higher rpm instead of having those spikes.
Also, in my opinion, only the CPU fans should spin faster but there is hardly any difference. The chassis fans are the ones that run noticeably faster when there is load on the CPU.

Oh well. Maybe I'll buy that fan controller soon. I can always send it back to Amazon if it doesn't work.

EDIT: Oh, the CPU fan rpm went up to 700 during load so there is a difference.

If you want it quieter when the fans speed up, take a look at fans with a lower max RPM... otherwise, with software (like that aquero PWM fan controller doyll mentioned) you can specify your PWM curve.

Personally, I just hooked the PWM splitter to my CPU PWM fan position and I let the mobo do its thing. Eventually I'll get a nicer mobo with the PWM software included but until then I'm happy to let this mobo work that for me. My fans are not loud at all at 100% PWM, just a woosh of air is all. That was exactly what I was looking for, low fuss, no muss. smile.gif

Sounds like the fan curve is using the ASUS turbo fan mode - too sensitive and noisy. Needs a fan curve with more hysteresis to smooth (ignore) small temp spikes. A system with a 6700k and a D15 shouldn't sweat even a little just opening a browser. What fan curves are setup in the bios vs FanXpert?

What MicroCat said. thumb.gif

Your temp to PWM siganl% is too sensitive, so fans are spinning up too soon. Fan speed shouldn't start ramping up until CPU temp is above 30-35c. There is no reason to keep CPU below 40c .. we just don't want it ever go about 65-70c .,. although even 80c rarely if ever damages or degrades life expectancy.

FanXpert is terrible. Just set up your fans in UEFI, or use SpeedFan if you need more control.

SpeedFan doesn't work on my motherboard and I can't set the fan speed lower than 47% in the UEFI. FanXpert and the xml file is currently the only way to adjust the fan speeds to my likings.

For some strange reason, the issue fixed itself. The fans still speed up a bit when opening the browser but nowhere near as much as a few days ago, it's barely noticeable. I guess all is well now? biggrin.gif

One strange issue though: when opening the web browser, the CPU temperate rises quite a bit (e.g. from 22°C to 51°C) which is also the reason why the fans spin a little faster. After 2 seconds the fans go back to normal and the same applies to the CPU temperature. Is that kind of temperature spike normal? The AMD Phenom II X6 1090T in my old PC never had these spikes. Then again, the CPU cooler fan was constantly spinning at 2000rpm whereas the idle speed of my Noctua CPU fans are around 300-400rpm.

EDIT: I'm measuring the temps with AIDA64 by the way. Strangely it doesn't pick up the temperature of my M.2 SSD anymore.

Congrats! Self-healing cooling systems will soon become all the fashion.

Can't quite compare the 1090T and the 6700k power states at idle. At idle the 6700k runs at near laptop levels of juice, but can slurp its way to desktop excess when required. If you want to reduce the disparity between idle and load could disable some of the power saving options in the bios. And boost idle temps. ;-)

Could play around with the power settings in Windows. Who doesn't like to have the power to play around with power?

At startup during boot the system is working fairly hard, so the temps are higher than after booting.

Ah, I see! I already had a similar thought in my mind. Thanks for confirming it.thumb.gif

There's also another reason why I thought that the temperature spikes aren't normal: the guy who built my computer had some problems with applying the Kryonaut paste. He had to add more paste several times in order to evenly spread it. Maybe it's not evenly spread or maybe we even used too much, resulting in worse temperatures? Should I run the Intel burn test to see whether my cooling solution holds up during load?

Yup, I noticed that myself. After 2 minutes or so the temperatures are normal. The spike is still there though when launching software.

Oh, by the way: Yesterday something really strange happened. I COULDN'T SHUT DOWN MY PC ANYMORE! O_o I chose to "Shut down" my PC at least 10 times but every time I was thrown back to the desktop screen after 2 or 3 seconds, it was like an ultra fast reboot instead of shutting down. I had to enforce the shutdown by logging out (to prevent data loss) and by pressing and holding the power button a few seconds. Not sure what happened there... the last thing I want to imagine is that my hardware is haunted. worriedsmiley.gif
