Well, it's not available from http://www.riscos.willowroom.co.uk/

An extra 25%? I'm not sure I would notice the difference for the
applications I tend to run, which are mainly limited by user speed,
not processor speed :-)

They need to revise the help file.

The 70deg is with the processor running 100% ("spare" clock cycles are
used by the distributed.net client)

Even when running the processor at 100%?

Again, that's with both cores running 100%.
Currently core0 83-85, core1 77-79
If I stop the d.net client they drop to 51-53 and 47-49
I run the d.net client 24/7 and the PC hasn't gone up in flames yet.
Maybe it will if the fan ever fails!
