NH-L9i CPU Cooler Low Profile - 92mm

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9x14 features an MTBF rating of more than 150.000 hours and the entire NH-L9i package comes with a full 6 year manufacturer's warranty.

37mm low profile
Due to the slim 23mm heatsink and the NF-A9x14 low profile fan that measures only 14mm in thickness, the NH-L9 stands a mere 37mm tall, which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers.

100% RAM compatibility
The NH-L9i has a 95x95mm footprint that complies exactly with the Intel LGA115x socket keep-out zone. This means that it won't cause issues with chipset coolers and doesn't overhang the RAM slots, so it is fully compatible with tall memory modules.

100% compatibility with PCIe cards on mini-ITX
Most Intel LGA115x based mini-ITX mainboards have the PCIe slot sitting right next to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-L9i provides full compatibility with PCIe cards.

NF-A9x14 PWM premium fan
The highly optimised NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9i to stay remarkably quiet.

Low-Noise Adaptor
Allowing a reduction of the maximum speed of the NF-A9x14 fan from 2500 to 1800rpm, the included Low-Noise Adaptor (L.N.A.) makes it possible to achieve near-silent setups using CPUs with less than 65W TDP.

Custom-designed SecuFirm2 mounting for LGA115x
The NH-L9i bundles a custom-designed, backplate-less SecuFirm2 mounting system for LGA115x that offers extended compatibility with mini-ITX boards and makes installation easier than ever, all while maintaining the trusted SecuFirm2 quality.

NT-H1 thermal compound
Noctua's much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.

Wow - Colour me impressed

The build quality is top notch which makes it worth the price as installation is simple - Keeping my i3 below 60 degrees at load and 34 degrees idle despite being a tiny case with restricted airflow. Most importantly for an HTPC in the lounge it really is completely silent! At 500-1200 rpm it remains inaudible. Never had to go above this during use yet when testing it was still "quiet" even at full tilt.

The included generous tube of thermal paste, Y splitter, low noise adaptor, screws and rubber mounts are all a nice touch making it much better value than "just a cooler".

Amazing for only 37mm tall! Nothing else compares at this size.

Very Impressed

Bought two of these today from Overclockers. Went and collected direct from their premises, extremely helpful staff member behind the counter. Easy to fit as the cases are HAF912 so have the hole to allow access to rear of motherboard. Cannot believe how quiet the PC now is. Running the two PC's together, you can hear how loud the old Intel stock fan really is. Checking on temperatures, it has lowered the mobo temp. by 1 degree. But the cpu and gpu run anywhere from 4-5 degree's cooler at idle. Also the fan runs 300 rpm slower. I have not fitted the low noise adaptor as it does not need it. Would recommend this cooler to anyone.

Beautifully finished. Easy to fit, compact and silent.
If your short of space get one of these!

HTPC cooler

This is a beautiful little cooler, usual Noctua quality and super easy to install + silent while running.

This is cooling my HTPC's i3 4130 in a Silverstone ML03 case. temp range from 30-35c doing everything I ask of it.


Great little cooler

A Really nice product.

A very nifty little cooler. Neat, compact, quiet, and perfect for SFF ITX cpu cooling. Really easy to install.
I have mine installed in a CM Elite 120 Advanced case which has the PSU mounted above the Mobo and very limited space for coolers. Many Low profile coolers have difficulty fitting in the 60 mm head room space in this case, but this fits with ease and room to spare for unrestricted airflow.

I have mine cooling my i5 3570k OC'd @ 4.2Ghz which runs happily at 60-61 degrees. I have had it up to 4.7 Ghz but it was getting a bit noisy and too hot for extended gaming use.

OC service was their usual high standard.
