[gentoo-user] fan noise in recent kernels
Hi, Maybe I'm imagining things but it seems that all of my machines have gotten noticibly noisier with some of the most recent kernels, ala 2.6.12-gentoo-r6 or -r9. Has anyone else noticed this? This observation comes from both a couple of Pundit-R's running mythfrontend as well as an Intel-based backend/general purpose machine. What packages would I look at emerging to better monitor control that sort of thing? Thanks, Mark -- gentoo-user@gentoo.org mailing list

This observation comes from both a couple of Pundit-R's running mythfrontend as well as an Intel-based backend/general purpose machine. My first guess would be that this is not related to the kernel version, but is more related to the aging of the fan(s) themselves. Fans do wear out over time (just had a switch that had two fans start squealing this week that needed changed). I'd suggest replacing the fans with some newer ones. Go the expensive route and get those quiet fans, especially for the myth box (last thing you want to hear is a fan when watching myth). Of course you can verify all of this by installing an old kernel and determine if the noise level drops, but I'd be very surprised if that is the case. -- gentoo-user@gentoo.org mailing list

You can control fan speed from /sys/bus/i2c interface. -- Regards Karol Krzak -- gentoo-user@gentoo.org mailing list

Hi Dave, Possible, but it seems to be a marked increase in noise, as well as two of the machines (the Pundit-R's) being quite new. Installing an old kernel is a possibility but I hoped to determine what sort of control Linux gives me over this part of the hardware before I went that direction. I Was at Fry's looking at new motherboards today and saw in the gamer's motherboards applciations for changing overclocking, CPU voltages, fan RPM, and lots of other stuff from within Windows, along with the ability to write it back to BIOS so that it's there for the next boot. I've not looked into this sort of stuff under Linux before. Thanks, Mark -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] fan noise in recent kernels
I couldnt find a good program to do this. I've rewriten an old piece of code to work with i2c. It's configurable and works quite well. If you like I can email the source to you.

You can at least look at the output in a neat and tidy manner with gkrellm. It can give you a running summary of fan speeds, temps and such. Humm... I tried gkrellm2 on one machine. It runs but I haven't figured out how to make it show me fans and temps. I wonder if this older Asus A7V266-E machine can do that? I also emerge gkrellm-sensors but I'll have to find some info on how to use that. Possibly it's part of the solution. Thanks, Mark -- gentoo-user@gentoo.org mailing list

Thanks, Mark Ok fair nough. I belive that gkrellm2 has most of the plugins as part of its emerge, sorta like a monlithic ebuild, wheras gkrellm-sensors is part of gkrelm version1. to configure right click on gkrelm and look for sensors under plugins. If everything is working, there should be a big list of checkboxes there you may enable. if you modprobe these modules *after* starting gkrellm it wont pick them up tho. -- I WILL NOT CUT CORNERS Bart Simpson on chalkboard in episode 7F11 -- gentoo-user@gentoo.org mailing list

OK, my bad for not seeing sensors in the list of things I could configure in gkrellm. I'm now getting 1 fan speed and 2 temp readings. One temp said 32C while the other said 68C. I ran glxgears for 5 minutes and watched those move to 33C 70.5C. There's a bit of a thermal lag. After I turned off glxgears the temp continued to go up for about 1 more minute and has now started down slowly. I suppose now the thing to do would be to run this on all the systems with 2.6.12-gentoo-r6/r9 and then see about building one of the earlier kernels and look for differences. Thanks for the clues.
