Introduction

If you search the internet looking for information on your next build, maybe some advice and pointers, from the experiences of people in your shoes, you’ll probably come away with more questions than answers. Lots of these posts ask the same question, “is this ok?” System builders, first timers or experienced, will also read reviews like this one and wonder if this is objective and impartial. The internet is a minefield of fake everything, and real everything too.

Today we are reviewing the Noctua NH-L9i Low-Profile CPU cooler, a case in point for try, try and try again, or at least, sometimes you just need to trust the specifications and marketing and go for it. You’ll learn faster and at least you now know and can answer some of those “is this ok?” questions.

A while back we contacted Inkubus, we had seen their 300µ mITX HTPC Personal Cube out there and loved the look, so we wanted in on the reviewing action. Inkubus were super supportive and we got a freshly hand built chassis for review. Our only challenge, a CPU cooler for the superb EVGA Z170 Stinger motherboard. We read some reviews and pondered, eventually putting our hands in our very shallow pockets and buying a Noctua NH-L9i CPU cooler.

We always strive to be objective, however, if there are any issues with the sample, we would discuss with the supplier first, this time, we won’t be.

The NH-L9i is a low-profile quiet cooler designed for use in small form factor cases such as HTPC systems. There is the NH-L9a for AMD processors also, so this review will apply to AMD owners too. This design has a compact set of fins, and a 14mm thick 92mm fan moving all the air.
