The NH-L9a is a premium quality quiet CPU cooler for AMD based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9a is ideal for extremely slim cases and due to its 92x114mm footprint, it provides excellent compatibility with tall RAM modules and other components on mini-ITX mainboards. The custom designed SecuFirm2™ mounting system for AM3+/FM1/FM2/FM2+ makes installation a child's play and thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9a runs remarkably quiet. Topped off with Noctua's renowned NT-H1 thermal compound, the NH-L9a fuses everything users have come to expect from Noctua's larger coolers into a super-compact package for slim HTPC systems.

1 out of 5 eggsGreat heatsink, very bad fan

Pros: The heatsink is great and do the job very well.

Cons: The fan started to make a loud noise after 2 weeks. I contacted Noctua who sent me a new fan. Same problem after 2 weeks with the new fan. I contacted Noctua again but I lost faith in them. I'll order a 92mm fan to replace the Noctua one.

5 out of 5 eggsQuiet, reliable cooling

Pros: Giant, quiet fan. Large, efficient heat-sink. Included thermal paste sufficient for several installations. Keeps my AMD A10-7850 CPU well within comfortable temp ranges, even under heavy gaming loads.

Cons: None yet. Works like a champ.

Other Thoughts: I purchased this cooler to replace the cooler/heatsink that came with my CPU. The stock cooler may have been sufficient, but I wanted extra insurance that my new PC would remain cool, and not suffer damage. So far, it has worked flawlessly, and keeps the CPU in the happy range at all times.

With good air circulation (a total of 7 fans inside my case), the fan on this cooler has yet to run beyond about 30%, and is by far the most quiet fan in my system. If using on-board graphics, I would expect the fan to run faster, but with a dedicated graphics card, the Noctua should keep your CPU happy with minimal effort.

2 out of 5 eggsDesign problem, noisy after a month

Pros: Beautiful packaging
Quiet (not silent) at first

Cons: Doesn't work in vertical orientation (tower case). After a couple months these fans start sounding like a cricket. Seems to only be reliably quiet if fan is horizontal. Other reviews are reporting the same exact problem.

Other Thoughts: Will contact newegg for alternatives.

1 out of 5 eggsAnnoyingly Loud

Pros: Looks good?

Cons: Extremely loud and annoying clicking noise... fiddling with it will sometimes help temporarily but requires taking my HTPC case apart. Fan is making the racket nothing from my case/wires are near it.

Unusable, in my situation the clicking and fan noise is unbearable.

5 out of 5 eggsSilent

Pros: Utterly silent at idle. At load it is a faint whisper. One of the quietest fans I have ever heard. I thought it was not even working at first. Comes with standoffs for boards that have circuitry where a backplate should go, so don't worry about trying to find a mobo with a clear "exclusion zone" under the chipset area.

Cons: none.

Other Thoughts: Currently cooling an A10-7800. The A10 throttles in games, and not sure if this is the fault of the cooler, but it's happening. The cooler comes with an underpowering cable connector you can hook up to basically limit the RPM of the fan for quieter operation. Even without it the thing is basically silent.

1 out of 5 eggsGreat cooling, but...

Pros: Amazing fan. Truly is. Install was kind of a hassle but with how low-profile the fan is and how cool it keeps the CPU, it was worth it.

Cons: What's NOT worth it is the amount of noise this thing makes. The first few weeks I had it, it was noise-free. Then, as other commenters have said, it starts making this SUPER ANNOYING clicking noise. I can't stand it. I've tried taking it apart, repositioning it, nothing. Will go back to my stock fan until I can get something else.

2 out of 5 eggsHas started making a rhythmic clicking noise after 4 months that is unbearable

Pros: It was quiet for the first month, now it makes a rhythmic clicking noise as if the blades of the fan are unbalanced and rubbing against some other part of the fan or heatsink. That said, the product seems to be high quality and the packaging made it feel premium

Cons: Now it makes a rhythmic clicking noise that motivates me to turn off my computer at night so I don't have to listen to it. Extremely frustrating. I just rebuilt my computer 4 months ago and I don't want to tear it apart again in a mini-ITX case just to replace the heatsink.
