But at that point I wouldn't really worry about noise anyway.Īlso, I kind of doubt removing the lid actually lowers the noise. As a server, hidden in a wardrobe etc - sure. You're OK with that? Because I wouldn't really like an open case on my desk. And a bit less functionality and esthetics. Maybe a possible mod would be to attach a slow-spinning 12cm fan on top of it instead of the original fan. I've removed the top plastic lid and it seems to help a bit to keep it cooler. Actual RPM is just some function you don't know. What you should worry is all the states that you're able to set (30, 40. That's how PWM fans work - they're powered by pulses.Īnd the relation between these PWM % (duty cycle) and RPM isn't linear (but may be fairly close). It means (at least should) that current is flowing 30% of the time. 8 reboots to BIOS? My coffee takes longer to make.ģ0% is not 30% of max RPM. I've tried it, but it doesn't update on the fly, requires a reboot Maybe something to investigate in the future when I get some more free time :-)īTW, quite a few brands are (officially) selling laptops and mini-pcs with Linux pre-installed. but I haven't found any pre-built mod for that. I know there are some fanless cases for this NUC, but they cost almost as much as the NUC itself. I also increased the increment from 1% to 2% (it's ok if gets noisy occasionally when it really needs to, but not constantly when it's mostly idle). I've also set the minimum rpm to 20% rather than 35% (which is the default for "Quiet" mode). It had the "fan off" threshold at 40✬, but when idle I was getting cpu temperatures slightly over 40✬, I've set the threshold to 48✬ and now the fan stays off most of the time when idle. "Quiet" wasn't quiet enough to me, but I started from there and ajusted it a bit. 100% results in 4300-4400 rpm, but lower percentages suggest the % is calculated in relation to 6000 rpm (for example, 30% will result in about 1800 rpm or so). I've tried it, but it doesn't update on the fly, requires a reboot to try a new speed. They usually use proprietary fan control software (just like NUCs). it doesn't work in most server rack units. Moreover, it's really not that rare for lm-sensors to not work. And these were serious problems with WiFi, BT, power management, speakers etc. I would still argue that NUCs are pretty Linux-friendly - given that they're basically laptops without the human interface and battery.Īpart from Dell (who sells a few devices with Ubuntu, so they take care of compatibility), I've never owned a laptop that was fully compatible with Linux - i.e. You choose another OS, you clearly like tinkering with your PCs. It's made for Windows in the same way Macs are made for MacOS. Well, as I said: Intel is not selling these as Linux devices and they don't really spend a lot on making them compatible with all the Linux tools. and usually I can read the fan speed in linux, I think this is the first one I have that I can't. I've owned many computers, laptops, mini-pcs, etc. In other words: if you force the fans to run even slower, you may notice a performance drop. What "quiet" does is really run the fan as slow as possible to prevent throttling. For everyone else this should be the default setting. It can make the NUC slightly warm, so I wouldn't recommend it for devices placed near your hands or a chocolate bar. You can check what is too much, although I'm not sure what that knowledge will give you (unless you're OK with running constant rpm, obviously). Among multiple options in fan control in BIOS you have constant rpm (in % of max).
