Noctua NH-U12F - The Silent Type
The NH-U12F by Austrian company Noctua relays the heat produced by the CPU to the cooling fins via four heatpipes. We should note that the manual that comes with this cooler is the most easily understandable one in the entire roundup - thank you, Noctua! Only a few glances at the manual tell you everything you need to know about how to install the cooler. Commendably, Noctua also includes a Phillips head screwdriver with its product. The only thing we could criticize about the installation is that it requires the motherboard to be removed from the case. Overall, the Austrians prove that even a cooler that is mounted using screws can be very easy to install.

Noctua NH-U12F
Whether the cooler is used at its highest or lowest speed, it remains completely inaudible inside the computer enclosure. A fan-speed regulator is not included.

Mounting Components
We recommend setting the cooler to run at its maximum fan speed, where it cools the CPU to 71°C. This is average cooling performance.

Retail box
In light of the cooling performance offered, we consider the price of $65 rather steep.

If my Artic silver 5 + Scythe Katana 2 cooler(for only a massive price of 25 USD! I can keep my outdated Pentium D under 100 degrees fahrenheit,infact around HALF of these tests,even under water cooling? Wow,according to this,I should actually worry about getting a quad core because of the heat.And no,I don't have any fans in my case,it's open,only fans are from my GPU,CPU,and my PSU.
No extra 4 250mm performance fans.And an X38? That's just unbelievable.
A good article, i especially like the tests for installation and sound, as those are what i would look into most when purchasing a cooler, and unlike CPUs, there are usually no charts to go along with.
but when installed in a normal ATX case, would be detrimental to the coolers performance. Especially coolers designed similar to the Noctua and Scythe Ninja plus.
I can't be certain about others but Arctic Cooling's Freezer 7 Pro is supposed to be installed like this(one would assume others of similar design would be the same)

As these have published manufacturer recomended installations why would you reverse it.
I recently read a review of the latest Noctua cooler at Legitreviews
where Noctua actually contacted them on this very issue... as a result they retested and found some improvement in cooling.

As said the Noctua is setup with the fan on top blowing down, which is the only config that Noctua dont support.
The Thermalright has the fan in the middle blowing up so it looks like there is no real consistancy in the test methods... but I would like to hear from the testers in case they found some reason to use each particular setup.
