comment Laptop running ~30° hotter than normal; CPU/Load is reportedly normal. What could cause this and how can I diagnose it?
@jmathew that's not a bad idea. I think it's reasonable to assume it might be a hardware issue. It already dual boots to windows, actually. The trick will be, as you say, waiting around for it to happen. The problem won't arise for days sometimes (it hasn't happened in 2 days now, on linux). As this is my work machine, it'll take some doing to get things rearranged to work somewhere else and monitor this. If nothing ends up coming from this bounty then that's what I'll have to do.

@xx4h 3.9.9-1-ARCH and no I have not tried to up/downgrade, however, this issue has been a problem for me through several kernel updates. I'll look into pcie_aspm. My problem with such advice, as my issue is intermittent and not reproducible, is that it's impossible for me to really tell if a fix is working without waiting indefinitely to see if the problem comes back. It would be great if there was some place to start looking for irregularities in log files, etc.

No, the problem still exists unchanged. I'm sitting here right now at 42 degrees. When my heat condition occurs I'll be running the same processes, the ambient will be equivalent, nothing ostensibly will have changed, but my temp will rise from a consistent 42 to a consistent 75+. I can cool it down: put it on a laptop cooler, disengage the fancontrol allowing to to spin at 6500 RPM, etc. But if I stop, it'll heat right back up to 75+. The fan at max speed is only slightly faster than it was going anyway. Fixing it was a good thing, but not a solution to the underlying problem.

I just installed thinkfan. Thanks for the heads up on that. Yeah the detailed arch wiki is a great perk of the distro. I've been there a thousand times but I never stumbled across or thought to look for a page dedicated to my exact model, and had never seen thinkfan mentioned. Nice little script. That being said, this doesn't solve my actual problem: how do I diagnose the cause of my unusually high temp? Even if I disengaged the fancontrol and cut the thing loose at max RPM, it's only putting a bandaid on the real issue of the mystery heat.

You're right that my fancontrol is working poorly, if at all. I'll look into getting it to respond properly, but fixing it isn't going to solve the underlying cause. I could let the thing loose at max 6400ish rpms all day and cool down a bit but its the cause that I'm trying to address.

@braiam nope, killing the xserver didn't solve it

@braiam I will try this next time it acts up. Today it's been running at normal temps so I can't test it until it occurs again. I use i3, which I have tried stopping. I don't recall specifically stopping X, but I feel like I probably did (as it's the next logical step). I'll let you know.

I didn't opt for the nVidia card on this machine. Sorry, should have been clearer on that in the question. And while 80-85 isn't too hot, it's still hotter than mid 40s, which is what my computer normally runs at on a typical light workload. My issue is trying to determine what phantom condition "kicks in" and causes my consistent 45 to be a consistent 80-85.

Nope, acpi is working, with the thinkpad_acpi module loaded as well.

Just to note, all my CPUs are running in powersave

The GPU was my uneducated guess too, now I just wonder how to diagnose it :-) Thanks for your patience
