Solved High temperature?

I idle 50C at max turbo (4.1GHz) and do 90C down to around 3.7GHz compiling or large extractions with i5-8400H. I'd consider temps high when clocks throttle lower than base because of temp (mine's 2.5GHz)

It depends on the CPU (its max turbo/boost clock and temp, along with how that tech works like SpeedStep vs SpeedShift, surprisingly even BIOS version) but if clocks dropped unexpectedly low I'd check the laptop MFG's specs (might use a small heatsink and intentionally have lower limits than the CPU MFG)

Where are those measured?

For the CPU chip, a temperature of 62 and 72 degrees C is hot, but probably not dangerously so. Around 90 things often get worrisome. Depends on what the cooling is supposed to be, and where it is measured.

You should try electric motors that drive fans and pumps. They are typically specified to be able to operate a full power at 40 C, and their coils can rise by another 90 degrees, which means they're at 130 C. Touching them at that temperature is right out, and they smell quite interesting.

Doing work (i.e compiling) that is pretty good. At rest, you generally should expect ~40-50.

What is your CPU's cx_lowest? With modern chips this seems to be more important than powerd (is powerd even effective for hwpstate_intel?)

Let me adjust that for you as a person who deals with hot metals.

Touching them at that temperature is right out stupid, and you smell quite interesting as the oils of your skin burn. Burn degree depending on reflex speed.

Make sure you load coretemp for readings. Clean fan and airways.

It's a bit warm, for an X61, although not really hot, I would regard something getting up to around 80 as being really cooking. Although tz0 of 72 is quite warm. I suggest take it apart and vacuum the dust out of the cpu fan. Those little fans do tend to get clogged up and it reduces their ability to move air. Also vacuum the dust from the air outlet grille. Or if the fan itself has gone... you can get spares on ebay. I found the best way is to hold the fan still with something like a small screwdriver so it doesn't rotate, and use an actual vacuum cleaner nozzle on low power, of course you have to be a bit careful, but it sucks all the embedded dust and dirt out. It helps if you've got one of the handheld battery powered vacuum cleaners. Another thing to look for on that age of thinkpad is the heatsink compound having dried out. There's a video here that shows you how to remove the heatsink. I've done it on that model, it's a bit of a fiddly job, but it can be done. If you do do that then get some reasonable quality paste like arctic silver mx4 to replace the old paste with, it's not worth putting cheap paste in. And you need to be very careful not to cross the threads when tightening the h/s screws back up. But I would try just vacuuming the fan clean first, that might be enough to lower the temp a bit.

Ah, I missed its an X61. I have two of these (great machines). They do actually tend to run a little warm. One more than the other interestingly. If I recall they were around 45-50.

They have surprisingly deep fans, so if you are careful, open it up and see if there is some clumps of dust in there
They are earlier than hwp_state intel, so powerd does help.

I also find setting the power level of the sata does help ahci(4). In /boot/loader.conf

Code: 
hint.ahcich.0.pm_level=3

Did you run through all the bits in here?
 
When the laptop is burning it's a sign.
No seriously, on my Dell 5590 i would say between 55 and 65°C during normal use. It's hot above here.

Yeah X61 is a nice little laptop.

I have several. One with an antenna stopped working when I tried a BIOS upgrade, and I've never found another one like it. Not sure how to identify them.

Many thanks for this. I will have to go through this link

That is very observant of you seeing a Japanese keyboard.

No I don't understand Japanese.

But if anyone is looking for an HMM or a good forum on ThinkPads check:-

So the X61 had one really annoying feature, which was that they put the wifi chip on the board just underneath the palm rest on the left hand side (or was it the right side? Can't remember). So your hand was resting right on top of the chip, just separated by a thin bit of ABS. The heat always used to irritate and "burn" the part of the base of my hand that lay on the palm rest directly above the chip. I actually used to take the wifi card out to try to make it more bearable. They fixed that on the X200 series. Great little machine otherwise. The ergonomics of the keyboard and trackpoint, and the screen, were classic ibm thinkpad design, and in a very compact and light form factor. Everything about it oozed quality and usability and human factors engineering. So different from the modern lenovo junk.
 
Or compare the X61 to this piece of junk. The X61 design is so far ahead, it's ridiculous. Unfortunately the market preferred thin and shiny! Yeah, I'm veering hopelessly off-topic. 😁

Actually thats a good point. There is a tiny little fan next to the wifi chip under the palm rest (presumably to keep that chip cool). In one of the machines this had actually broken, causing it to get very warm. I wonder if this is contributing to one of balanga's sensor high temps.

Yes some of them had that little fan, I think they put that in some of the later ones when people complained about the burning. Unfortunately none of the X61's I had actually had the fan!

Is it contributing to the heat? Well, possibly, the wifi card does get pretty hot, though it depends where the thermistors for tz0 and tz1 actually are in the box. The technical manual might say. You could always take the wifi/bluetooth card out, its only a mini-pci card, just be careful with pulling the little aeriel cables off, and unscrew the small silver screw in the corner first of course. It depends on whether OP wants to use wifi or is happy with the RJ45.

Actually the laptop with a problem has just switched off with a message that the temperature was too high.. it may have said something like 128C.

Time to install a new fan!
