Noctua NH-P1, Passive CPU Cooler - Fanless Heatsink for 100% Silent Cooling

When I bought this to replace my dying AIO, I assumed my temps would increase and I would have to upgrade somewhere down the road, but suprisingly my rig has gotten better temps since making the switch, and as advertised it was completely silent (cuz no moving parts, duh). The build quality is great and it was easy to install, and thankfully it was able to fit in my case despite the comically large size. Overall I've been very impressed with its performance, and I see myself using it well into the future!

Length of ownership: 3 years+. Works great on my silent PC i5-12500. Installation was straightforward, though it was a tight fit in my medium tower case.

We don’t have a ton of passive coolers on the market anymore, but I’m glad we have this one. The tolerances are tight, it’s easy to install, and it works much better than I expected.I’m running a 5800x3D in the same case as a 3080 ti. This isn’t the coldest running system, but this cooler has kept my cpu under 65 C while under load. I do have two Noctua fans in the front of my case that provide a small amount of airflow, but that seems to be more than enough in side of my NZXT 510. This case is notoriously bad with air flow, but this cooler handles it like a champ.Keep in mind that higher end chips with higher TDP will require a tower that has some sort of active airflow. If you’re looking at purchasing this cooler you should already know how to set your fan curves accordingly.If you plan on using this in tandem with a totally passive build proceed with caution when dealing with any cpu that has a TDP higher than 100 watts. It will run well for a while, but you will fall out of boost clocks when the cooler gets heat soaked.I’m a big fan of this cooler, because I can set my fan curve to keep my fans off under most light to moderate loads. This also has the added benefit of no moving parts. No fan to go bad, no pump to clog, and no water levels to maintain. I will be long gone before this cooler goes through enough heat/cooling cycles have an effect on performance.

I used this to build a silent storage server with an AMD Ryzen 7 5700G processor, and it works excellent. I combined it with a fanless power supply and SSD drives to make a completely fanless and motorless system. Normally the CPU temperature hovers around the 45-55c range, and during an AV1 video encoding task the temperature hovers in the upper 80c range, but doesn't get into the 90's. Now if I run the Linux "stress" command which maxes out all cores at 100% then the processor will gradually work its way up to 95C but not go past that. Of course the "stress" command doesn't represent a normal CPU load.Now there are a few things to be aware of. Since this is a storage server I don't have a video card in the system. Instead, I have a storage controller card and there is just enough room under the heat sink for it to fit, but it is very close. I also have the system in a large case with an open vent at the top. I believe the top vent is very important because I can hold my hand over it and feel heat from it. Also, make sure that your case is wide enough. The case that I am using had some plastic brackets on the side cover for mounting a side fan, and I had to remove those brackets for the side cover to fit.

I've decided to upgrade my silent pc with AMD Ryzen 5 3400G rated at 65W TDP to AMD 5950X rated at 105W TDP. As you know, AMD 5950X has 16 cores and 32 threads, and it's rated pretty good. Previously, I was using Nofan CR-80EH as CPU cooler for AMD Ryzen 5 3400G, and it worked out pretty good.Now that Noctua fan-less NH-P1 is out, I've decided to try it on AMD 5950X. Remember, Noctua does NOT recommend fan-less pairing of Noctua P1 and AMD 5950X, and Noctua recommends adding a fan with AMD 5950X. However, I've decided to pair Noctua P1 and AMD 5950X in a fan-less configuration since I don't play games on it and mainly use it for YouTube, movie playing, browsing, music listening.Here is the trick I use to keep the CPU from heating up too much and under-throttling the CPU:I set the maximal CPU Thermal Throttle Limit at the motherboard. Most recent X570 based motherboards will support this feature.Here is how you do it in case of ASRock X570 Phantom Gaming 4:I.e. Max temperature of AMD 5950X is 90°C.This means, when CPU reaches temperature of 90°C,it will automatically reduce CPU clock speed to cool down.So I'm setting the maximal CPU Thermal Throttle Limit at the motherboard to be 83°C.And I've noticed that it does good job staying around between 83°C and 85°C.F11 to Boot MenuAdvanced Mode > AMD Overclocking > Precision Boost Overdrive > PBO AdvancedPBO Limits: MotherboardPlatform Thermal Throttle Limit: ManualPlatform Thermal Throttle Limt: 83Hope this helps ^^

Works great at passive cooling but I am in a bind looking for upgrades since the am5 mount that should have been included is missing
