You're making me bigger than I am :-) ("Lipa" is polish for lime 
(linden) tree; "Lipka" is the deminuitive form; the "C" is from 
"Christoph".)

As implemented in RC3, SSLT shoots about half of its rays only against 
the SSLT object itself, which might result in fewer cache misses than 
other ray-tracing computations. In addition, SSLT does a lot of math, 
with many exp() and sin() and cos() and such, so the floating-point 
units are probably running near full-throttle.

When I got my i7, I was worried about the high temperatures, too - but I 
was assured by the local PC dealer that this was nothing to worry about, 
since the i7 would self-throttle when in danger of overheating.
It doesn't - to the contrary, the cooling in my PC is apparently so good 
that the CPU keeps overclocking itself even with POV-Ray blazing away.

Apparently the i7's temperature sensors measure the temperature at 
totally different places than its predecessors. I heard that earlier 
Intel CPU's measure the temperature of (or near) the heatsink, while the 
i7 measures the core temperature.
