Summary: Noctua's low profile NH-L9i heatsink stands 36mm tall so it will fit into the smallest of small form factor chassis. The NH-L9i is designed to cool Intel socket LGA115x (1155/1156/1150) processors only, which is a departure from the one-size-fits-all approach we're used to.
Summary: The Noctua NH-L9i is a premium heatsink designed for systems where space is an issue and noise control is of utmost importance like a HTPC and SFF (Small Form Factor) PC. These systems often feature half height chassis designs and sometimes have the PSU directly over the CPU both of which limit the size of your heatsink. The Noctua NH-L9i is designed to address these issues and boldly cool where no other cooler can.
Pros: Low Profile Cooler, Silent Operation, Large Mass Design, Better Than OEM, Perfect for HTPC
Cons: Limited heat capacity, Clearance issues with some pwm heatsinks
Summary: This small cooler packs all essential technologies of our awardwinning
high-end models into a highly compact package in order
to give you the best possible quiet cooling experience for HTPCs
and small form factor builds. I’m confident that you will be able
to sense some of the research, attention and care we’ve put into
making this product.
Enjoy your NH-L9!
Their confidence is well placed, again they managed to perform even when I thought it wouldn’t!
