Noctua NH-U12P SE (1366)

The Noctua NH-U12P SE is a socket 1366 CPU cooler redesigned for Core i7 CPU’s. See how the Noctua NH-U12P compares to the TRUE 120 when both coolers use the same fan.


There comes a time in every reviewers life when they get swamped, it’s just part of the process. Recently we got 4 CPU coolers that came in on the same truck. Quite the surprise to say the least. We saved the best for last, the Noctua NH-U12P SE 1366. A cooler that rivals the legendary TRUE 120. We wanted to see just how much it rivals the TRUE 120 on a level playing field so we’re going to use the Noctua fans that came with the NH-U12P on the TRUE 120 and put them head to head on the Core i7 965 Extreme and see which one stays on Quadzilla. Searching for the best air cooling alternatives has been a long road and one with no visible end. We’re about to switch back to water cooling on the test rig because i7 reviewing has slowed down enough to dip below the insanity level. In the mean time lets get back to the Noctua NH-U12P revisit.

    The Noctua NH-U12P comes in a sturdy box with plenty of information and specifications to help inform the potential consumer about it’s features and specifications. Inside the outer carton the NH-U12P is well protected and ours arrived unscathed despite the shipping carton suffering substantial abuse in it’s long journey here.

    We’re plesed to say that the Noctua NH-U12P has a quality look and feel to it that you seldom see in a CPU Cooler. All the vanes and surfaces are nice and flat and there was no deformation of the vanes to disrupt airflow. The base of the CPU cooler is nice and flat and well milled for a commercial CPU cooler. There were a few mill marks on the CPU cooler base that could have been a little better but we’ll just have to see how much that affects the performance a little later.

    One of the things we liked about the Noctua NH-U12P SE1366 is that right out of the box it comes with two nice Noctua fans and the mounting wires for dual fan mounting. No more big Blue Rubberband holding on the second fan. You also get a tube of Noctua’s NH-H1 Thermal Compund which we will be using for the testing portion on bothe the Noctua and TRUE 120.

    This is a Core i7 (Socket 1366) specific version of the cooler and you get enough hardware to mount the cooler on the Socket 1366 platform. If we had one gripe about the Noctua NH-U12P it would be that it’s not a universal mounting kit but when you buy the product it plainly states it covers the 1366 platform and no others so we’re not going to hold that against the cooler. Still a LGA 775 and AM2/AM3 mounting bracket would have made it a better value. It’s not an issue for most people but for review purposes we like versitile hardware.

    The finally the fans installed picture with the cooler ready to Mount. Mounting was an easy process but unless you have a compatible, existing backplate you will have to remove the motherboard to mount this epic cooler.


    To test the Noctua NH-U12P we mounted it on our Asus P6T Deluxe with the Core i7 965 for the CPU. We didn’t bother with a fresh load of Vista 64 because it’s not important in CPU cooler testing. As long as we can fire up Prime95 for 30 minutes without the rig crashing and idle at the desktop for 30 minutes we’re good to go. The P6T Deluxe is one of the boards with a lot of taller cooling implements around the CPU socket so if a cooler fits on this board, chances are it’ll fit yours.

    We Idled the machine for 30 minutes and took the Idle temperatures. Then, without shutting it down we ran Prime95 for 30 minutes and took the load temperature. After getting the load temperature we shut it down for 30 minute to cool it off then repeated the process three times for each cooler. The average of the three test runs are reported here.

    Please note that we included our Swiftech Custom Water Loop in testing but only for informational purposes. Comparing air cooling to water cooling isn’t something we do but we wanted you to have the information about the water loop temperatures. Keep in mind the custom water loop is valued in excess of $200 (USD) and the air coolers cost much less. That’s another reason comparing custom water to air just isn’t fair. However, if you’re looking for better cooling than air the testing numbers are there for you.

    It is important to note that we used the Noctua NF-P12 Premium fans in a dual fan configuration on all the coolers to make sure we had an even playing field. Use of different fans will result in different results. Results will be similar with most models of 53 CFM fans. In testing the coolers we saw very little advantage going to two 73 CFM Yate Loon fans and in most cases the increased CFM fans resulted in a one to two degree difference tops.

    Testing Results

    Please note that the Noctua is actually the NH-U12P SE1366, we had a Doh moment when charting 4 CPU coolers in one day and mistakenly labeled it the NH-C12P when in reality it is the NH-U12P. Our apoligies for the mistake.

    Of all the coolers I’ve tested these three quickly rise to the top of my preferred CPU coolers for Core i7 processors. The Titan Fenrir doesn’t have quite the cooling of the other two and comes with one fan. The TRUE 120 a long time favorite comes in 1° C cooler at load than the Noctua NH-U12P SE1366 but a difference in testing results that small might be attributed to ambient room temperature or the amount of thermal paste. With the TRUE 120 RT coming with one fan and costing more than the Noctua NH-U12P SE 1366 which comes with two fans and clips for both it’s cheaper to run the Noctua NH-U12P SE1366 than the TRUE 120 RT and the results are similar. By the way the custom water loop isn’t in direct contention, it’s a different type cooling and only included because of an upcoming review of a dual triple radiator system from Swiftech. (Dual Stacked Triple rads, drool)

    We’ve never found any air coolers that will keep the Core i7 965 Extreme cool enough for our tastes when we clock it to 3.74 GHz of all the coolers we tested so far these are the cream of the crop. After 30 minutes Prime 95 driving all 4 cores (8 virtual cores) as hard as they can go with no break we hit 73° C on the TRUE 120 RT dual fan configuration, we still see a 1° C difference between the Noctua and TRUE 120 RT. With that small a difference it would be a hard call to choose the TRUE 120 RT over the Noctua NH-U12P when a little additional chassis cooling could easily make up the difference. The Titan Fenrir is right on the tails of both the TRUE 120 RT and Noctua coolers and is the least expensive of the three. If a person cared to carefully lap the NH-U12P SE1366 we’re betting they could shave a degree or two off the temps.


    The Noctua NH-U12P SE1366 with it’s two NF-12P Premium fans and included NH-H1 thermal compound is a great choice for the Core i7 platform, and let us attain an OC of 3.74 GHz with almost identical results as the more expensive TRUE 120 RT which only includes on fan and mounting for a single fan leaving you to improvise a second fan holder. The additional items in the bundle of the Noctua NH-U12P SE1366 make it a good and economical choice for high end air cooling on i7.

    Like we mentioned if it came with a universal mounting design it would be a better valuse, but the additional hardware might drive up the cost a little bit. Mounting the massive cooler required removing the motherboard but you can expect that with any massive tower cooler of this caliber.

    We especially liked the sound dampening kit that comes with the fans on the Noctua NH-U12P SE1366, it never hurts to have vibration dampening because we like a nice quiet system. We tried the cooler with and without vibration dampenind and while it’s nice to have we don’t think the cooler really needs it.

    In all we like the Noctua NH-U12P SE1366, great cooling, vibration dampening, everything you need in the box, and the Noctua name behind it.

    We are trying out a new addition to our scoring system to provide additional feedback beyond a flat score. Please note that the final score isn’t an aggregate average of the new rating system.

    +  Lot Of Value With The Bundle
    +  Great Overclocking Result
    +  If It Holds The Core I7 965 Overclocked to 3.74 GHz With Hyperthreading Turned On The Noctua NH-U12P SE1366 Will Cool Any CPU Out There Well Enough For 98% Of Enthusiasts


      Not Universal
      Might Not Fit In Some Chassis
      Might Interfere With The Ram Slots On Some Boards

    The Nioctua NH-U12P SE 1366 gave us some nice overclocking headroom on the Intel Core i7 965. We took it to 3.74 GHz and felt safe running the CPU wide open at that with the Noctua setting on top of it, so the NH-U12P SE1366 scores a: 8.5 out of 10 and receives the Bjorn3D Seal of Approval.
