My CPU is constantly at around 85-90 C

I'll chime in, but only to say this, as clearly as possible, so as to help you guys distinguish real cores, hyperthreading, and logical cores.


Gee thanks, Jake, but I'm quite aware of the diff between real cores, logical (virtual) cores and what hyperthreading is. I suspect Dirk is too but maybe an unfortunate choice of words on his part led to my not understanding him. I don't see any sense in my responding with recommendations to something I don't understand unless it's just to say "I don't understand" or "you're talking gibberish".

I'm sorry. I knew there was a chance that what I'd post may come across as "talking down", and that certainly wasn't the intent.

I was merely trying to make it clear, for Dirk especially, that a quad-core hyperthreaded CPU has 4 real cores, 8 virtual cores, and likely only 4 CPU temperature sensors. I use CoreTemp to monitor the temp and load on each real core.

And I set BOINC up to schedule 8 CPUs worth of tasks, to ensure I can take advantage of any hyperthreading gains that might occur when running 2 threads on a single core. As such, CoreTemp always shows all 4 cores as 100% loaded.

No problem :-) Been doing this since early FidoNet days, I usually don't take offence and don't hold grudges. Due to limitations in this form of comms as well as user time constraints I take it all with a grain or two of salt.
