I’ve had Noctua case fans from the start of this build. With that the CPU cooler was noticeably noisy when trying to game quietly. I decided to acquire another Noctua fan for the CPU when I upgraded it. This thing is almost silent.
Cools well enough
Great little cooler... premium engineering - worth the upgrade over stock, even without low noise adaptor fitted. Bundled with good thermal paste and a snazzy owl badge, was super easy to install. Keeps an i5 4590 at 33-67 degrees in a tiny rig...
Its doing the Job and it seems the temps went down a few degrees,they were idle at like 34 - 35c now they idle around 25-31c.
I only have one complaint the Thermal stuff they give ya is only enough for 1 application :( was going to use some on my other computer but it wasn't enough.
Hopefully I didn't put too much on,well I guess if I did it would be flipping out by now lol. I did the Pea method.
Purchase was worth it :)
Great low profile after market cooler. Really quiet!
In the Silverstone SG-13B case there's very little space for any sort of a fan-based cooler and the manufacturer recommends an AIO water cooler for higher-power CPUs. I'm running a 65w CPU so figured I could get by with a decent air cooler and of the ones that fit the NH-L9i appears to be the best of them. It very precisely fits the space allowed for in the Intel specs and unlike some others does not presume there will be any surrounding space on any side for the odd heat pipe or other appendages. It's a perfect 95x95mm square just like it's supposed to be.
Thermal performance is fantastic for such a small cooler and it's reasonably quiet as well. I torture tested the CPU and temps maxed out at 62C.
There are better coolers if you have the space, but if you don't, this is arguably the best you'll find and it's pretty much guaranteed to fit.
Like other Noctua sinks it is quality and operates quietly, but unfortunately the cooling performance is merely par for the form factor and not significantly better than the competition while being more expensive. I chose this for the quality fan bearing building for someone else, so that they will not run into any issues for years and years, and that makes it worth the money. However, if just talking about performance, the price premium is not going to buy you any more cooling.
Can't even hear it.
Fantastic, quiet and keeps the processor cool. Even when I tried it with a higher-powered CPU (80w), it performed adequately, keeping temps under 65C. With the 54w TDP processor I am currently using, it keeps temps under 55C with very low noise.
One note: Depending on the motherboard, it may be necessary to take care about how you mount this one. There is often a line of capacitors on one side of the CPU socket that can interfere with the CPU cooler if it is not mounted in the proper orientation. One side of the heat sink has a slightly greater clearance than the other three and that one needs to be lined up with the capacitors.
Really amazing cooler, to be expected from noctua The bearings are really really good on the fan and it's got a low profile. The low profile wasn't needed for this build but we both wanted to see how well Noctua fans really perform.
