Now we can learn about new coolers and improve our Russian vocabulary at the same time!
As regards Linpack, though, the 64-bit version yields a noticeably greater power dissipation than the 32-bit one, so it might be preferable to test using that in the future. One can also choose a larger problem size, whereas it's capped at about 2GB in the 32-bit build.
Anyway, a disappointing result from this cooler, but not entirely unexpected. The use of the TEC in this fashion is somewhat ingenious (unlike in other implementations, if the TEC fails, then the cooler doesn't stop working entirely), but I agree that the extra complexity and expense is not warranted for the minimal benefit it provides.
