See my other reply to you.

Fine. His machine has, at best, marginal cooling. In fact, he
may have clogged fins on his heatsinks. I haven't argued against that.

I haven't argued against that.

It is not, because Linux is not intended to utilize the CPU like that.
My machine normally runs 4% to 8% utilization, most of that being
in X.

Saying that about an arbitrary piece of software would be silly.

My suggestion is simply to find out whether his CPU is being consumed.
If it is, then we can find out what is consuming it. If that is some
application he runs which we know is CPU intensive, then that's what
we expected.

But if it is something which is not supposed to be CPU intensive, we
can investigate that.

What I suggest is finding out.

I'll repeat this: I'm having no problem with my machine.

Next, I'll point out that what I've been suggesting is exactly that:
Let's find out why the machine is overheating. The first thing
I'd like to check is whether some application or kernel thread
is consuming an unexpectedly large amount of CPU.

Yes, he has a problem getting rid of heat. But why can't we at
least see whether X or some other software on his system
has gone crazy? Likely not, but if so, then we have a chance
to find out what it is and why it's crazy.

Also, he needs to see why his machine can't get rid of the heat.

I can explain it for you, but I can't understand it for you.
