The fan appears to be able to spin at reasonable speeds, since it reports 3900 RPM at some times. Based on previous experience, if the fan sensor is as accurate as before, this report should be taken as exact. However, this fan speed is only reported for a very short amount of time, as if the cooling policy specified to turn the fan to full speed only between 60 and 62°.
Question is not so much if it doesn't overheat anymore but if it takes longer. I'm not using the compressed air as I find it's pretty much impossible to really clean the parts properly with it. It just doesn't generate enough force. Especially in spaces that are enclosed a lot.
It's just easier to take it apart. You can find service manuals that guide your step by step through the disassembly on the notebook's manufacturer's web pages.
There is no sign that it overheats any slower. To be 100% sure, I should have measured the time before and after "cleaning", but my rough estimations will have to do. As for taking the netbook apart, this is a step I will not take. The compressed can thing was easy to test, and I should have had one of these at hand for a long time anyway. Taking the computer apart will take an afternoon, and I have no certainty that I will be able to recreate a thermal contact as good as the current, or even that I will be able to reassemble the netbook at all. The computer is not entirely functional with this thermal issue, but it is still way more useful than a brick. I know how this whole story looks like, but you have to believe me, I had this kind of issues twice already, and each time it was caused by a software issue (combination of drivers, grub options and bios black magic). Here the problem appeared with a system update, and it has at least one purely software symptom (the fact that I cannot get manual control of the fan, I am not even able to manually stop it). Could we please try to investigate this? Thibaut -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
