I ordered the fan for Intel socket 2011-3. On the German website that is so released. The supplied mounting hardware did not fit on the board - that are two points deduction. I wrote to the German service (on be-quiet.de). Who has reported immediately and the missing parts resupplied free. This is again a plus point. Power four total.
Parallel I have the seller okluge written. The only reacted on my second mail and he remembered only one that I should like to address the Amazon Returenabteilung. This also helps not at the PC assembly.
However, the missing pieces are probably not an isolated case. In the very short installation manual, the 2011-3 is not provided. Anyone who wants to use the cooler for a Haswell-E (Intel 59x0k), should ask in advance whether the appropriate mounting parts are included.
