Acoustic PC was kind enough to send us not only the NH-U12P SE1366 CPU Cooler, but they included the Noctua NH-C12P for comparison, which can also be mounted with the SecuFirm 2 system onto an x58 motherboard. Although the NH-C12P is not sold with the mounting equipment for the LGA1366 based motherboards; that problem can be easily resolved by picking up the LGA1366 SecuFirm2 Mounting-Kit from Noctua.
