HIGH POWER® LGA-115x-mITX has a height clearance of only 26.95mm to fit in mini ITX & 1U cases. Although it is lower profile than the stock Intel fan, its large 80mm fan delivers cooling capability that is not compromised. Set your BIOS to silent mode will enable the fan to start spinning at around 1100 RPM when it would be amazingly quiet. Noise level remains to be acceptably low during normal system operation. LGA 1156/1155/1150/1151
