Pros

Fan is nice and silent as well, as expected from noctua. When just browsing the internet, watching movies or doing lite gaming it is cool and mostly silent. When you need a low profile fan that also keeps your cpu running smoothly, and doesn't make an... Read More

Ymmv! My knowledge level is high, ymmv! Worked like a charm. Nice and compact.

Noctua am4 low profile cpu cooler is precisely what i needed to complete this build inside of the fractal terra case. Low profile, plenty of clearance with the top of the case in this small server case. This was used in a mini-itx build in a meshilici... Read More

nothing major but kind of awkward to install. Packaging feels very nice, and installation is very easy with noctua's signature secufirm. Easy to installed. Simple to install.

Cons

This gives plenty of space, but compared to the modified wraith cooler that i had previously, this cooler doesn't cut it. My temps are now down to 30-40c when idle and 50-75c when under load. Don't use this on 8 core cpu's.

Quality

High quality, feels very good in the hand, really easy to install and nearly silent.

High quality, quiet, and keeps my cpu nice and cool.

Those that know this product it is a very very small system that can fit small graphics cards in them.

While the l9x65 technically fits in a 2u, there is barely any room for the fan to circulate air once the top is on.

Price

Good price for a quality low profile heat sink.

It's nice and quiet but for the price, i thought it would at least keep my cpu in normal heat range.

Packaging/appearance

With the wrath stock amd cooler my x300w build with a 5600g cpu/apu was hitting 91c under intell burn stress test on all cores ... Read More

Competitiveness

Obviously, the beige and brown color scheme is not the most modern of options, but i've grown fond of it somehow.

Used this to replace the amd supplied cooler in a small home media server.

This was a gamble but managed to hide under the cd drive and is also much quieter than the amd cooler.

Also, it's quieter than both the old hp cooler and the amd one.
