This appears to be a different issue from the one I am seeing. The
system is very responsive at first and only under load (and with rising
temperatures) becomes extremely sluggish. As load (and temperatures)
drop, the system becomes usable again. Also, there is no difference
between Qt and Gtk

Yes, I tried this a while ago, before messing with the DSDT. I figured
it was unlikely that Dell shipped a DSDT which leads to 0°C re
The specified maximum CPU temperature is usually the same at the ACPI
_CRT, not _PSV. That is the temperature when an ACPI shutdown should be
triggered, but TCC should kick in at some point below this.
This laptop is a replacement for an earlier one that had similar
overheating issues. On that

Have you tried just using dd to copy the iso image of a Ubuntu / Linux
LiveCD to a suitably sized USB memory stick?
It has worked for me in the past.
As per Mehmet's tip, I did just that with a Debian image. If it works
for Ubuntu images as well then I really wonder why the only documented

I could be wrong, but in my experience this really sounds like it is
a hardware problem with the cooling system, and a very serious one at
that. I would encourage you to take this up with Dell at once.
Yes, I will. They have exchanged a lot of components already though

Thanks. I downloaded the amd64 image. It booted perfectly after copying
to a USB key via dd.

If you boot into another operating system such as Linux or Windows, do
you see the same overall behaviour? Linux might be easier and might
have some built-in way to get at CPU temperatures (via /proc?).
I finally found a working USB Linux image and have run some tests:

GRML ISOs (from grml.org) can be dd-ed directly to a USB stick and
should then boot with any reasonable current BIOS.
Thanks. It is great to see that so many ISOs can be dd-ed to USB keys. I

images and which do not. I am reluc

I agree. tz0 looks entirely bogus. There is no second fan to control for

dev.cpu.X.freq does reflect the current frequency; I don't know whether
or how any internal clock throttling might be exposed.
From what I have seen, dev.cpu.X.freq always retains the value I set it
to. Internal CPU throttling does not seem to be reported this way.

As the processor gets hotter, internal clocks and so on are throttled
within the hardware to try and stabilise the temperature (to keep the
thermal trip point being reached, re: "emergency shutdown"), which
greatly decreases performance. I'm not sure if there's a way to
detect this, but I would h

I don't know which i7 you have, but the intel datasheet for the i7-870 states
that the maximum case temperature is 72.7C.

had a Q730. Both were exhibiting the same problems.
