Hi guys, this is just a personal impression so that’s why I post it here and not in the tech help forums, since I don’t want to take the place of someone who is really asking for help.
Thing is, the dreadful Southern Spanish summer is coming and with it the typical 45ºC days that make our processors so much good. I had noticed that with the 3.11 kernel my laptop regularly reached 80ºC in the micro, which is calling for disaster. I updated to the 3.14 (if His Torvaldsness refuses to call it Pi, 3.14 it is) and after a couple days with the same results, a new release of patches that I installed immediately had an awesome effect: with the same usage, my micro rarely exceeds 70ºC, with no performance loss. Right now the temp is pegged at 61ºC, which in a 2011 laptop that still uses the factory thermal paste is quite good.
I don’t know if it’s just a personal impression but it’s a really awesome development. Just by updating a kernel you get a 10ºC+ cooling factor, which makes this upgrade not just metaphorically but literally cool! What do you make of that?
I get numerous laptops here that have nice collections of dust buildup between the fan case and the cooling fins causing over heating. Disassemble, clean fan assembly and new heatsink compound and re-assemble…

I cleaned it up several months ago but didn’t disassemble the fan from
the CPU.

You must live in the middle of the “pan”. I seldom reach 40 in summer,
but then it doesn’t drop below 35, either.
My laptop CPU doesn’t run hot. But it is just a plain core2 duo, not top
speed, plain Intel graphics… What gives me problems, I think, is the
HD and perhaps the RAM (I had to replace the HD), so I use a plastic box
with a big fan, and the laptop sits on top if I’m going to use it for 10
minutes or more. It plugs into the USB socket, but I run it instead from
the mains via an adaptor, in order not to stress the laptop power supply.
The snag: it is noisy.

Sorry, I’m a newbie to openSUSE and still get easily lost.
Hi
Download and install the rpm, then as root user;
systemctl status radeon-power_profile.service
systemctl enable radeon-power_profile.service
systemctl start radeon-power_profile.service
Give it a bit of time and you should see the temperature drop…

EDIT: I searched a bit and found out I have to open YaST and in System Monitor choose radeon-power_profile and set it to low, which is already the case. Nevertheless I have not noticed any significant change from before, micro is currently running at 66.1ºC.
Thank you so much Malcolm! I see now that it was disabled, that’s why it had no effect. Have run all those commands as root and temperature has fallen by 3 degrees in 2 minutes, pretty impressive! Did you code that tool? if so, you should be really proud of yourself, since I have noticed no performance loss at all.
+45? I did regular lived in a environment that had up to +52C. It did not affect computers to hard thanks to effective AC. A problem was that some hearing problems could be heard of in the affect of AC-fans. Not PC-fans.
In the last 10 days we had snow, dripping rain and max +4C here. Of course I have “nature cold” in the summer beacuse we actually had varmest in EU some years (+33C) and Veeeryyy long days during summer as everybody in north.
I have to say that I don’t are familiar with the temps you are mention. I had some problems on my HP 6730B (2007 ?) and one version of the kernel/regression of temperature/full speed on fans in laptops. The solution was to downgrade opensuse then.
So the development goes forward :P. Good. I does help with a push of compressed air trow the PC to get rid of dust as well from the cooling mechanism.
