I suspect temperature can have an impact on performance if Turbo is
enabled (or, as you noticed, if CPU cooling is deficient).
Note that tweaking a system for benchmarking (disabling Turbo,
disabling ASLR, etc.) may make the results more reproducible, but it
may also make them less representative of real-world conditions
(because few people disable Turbo or ASLR, except precisely on
benchmarking machines :-)). It's a delicate balancing act!

Antoine.
