Thermalright SI-100 Black CPU Air Cooler, 6×6mm Heat Pipes, TL-E12B PWM Quiet Fan CPU Cooler with S-FDB V2.0 Bearing, AGHP 3.0 Technology, for AMD AM4 AM5/Intel 1150/1151/1200/1700/2066/1851

I needed a smallish simple to install cooler to use on my test bench occasionally and didn't want to spend a ton of money. Threw it on my i9-12900ks running the standard clock frequency with the power limits unlocked and my custom undervolt profile. To my surprise this little cooler performed better than I expected. For everyday tasks it was basically silent. Running Cinebench R23 with the fan at 100% was noticably louder but acceptable and kept the CPU from thermal throttling right away like some other coolers I have tried.While gaming the CPU stayed around 60-70c depending on the game and how hard it was pushing the CPU. I'm normally a custom water-cooling snob but I would have no problem using the cooler on a less extreme CPU. And for $26 this is now my favorite CPU cooler for under $30 dollars. Ironically enough, the Thermal Grizzly Graphine thermal pad I used with the cost almost as much as the whole cooler lol.

The price is low and the performance is very high for a 120mm top down style cooler. I put it on a Ryzen 7 5700x in a custom made small form factor case and it performs beyond expectation. I've installed tens of dozens of coolers if not more over the years and the installation was simple and straight forward.All thumbs up.

Nice cooler has good temps on my cpu. It was a little hard to install the red spacer for the cooler and they are very hard to get off if you want to change coolers. Had to put a lot of pressure on the motherboard.

Worth the price, keeps my CPU at the perfect temps.

Purchased two of these for new builds earlier this year, last last year. Both 'Fans' seem to make an odd noise. I have tried taking the fans off, cleaning, putting the fans back on but they both have the same issue. It is a sound that goes on a cycle. Kind of sounds like a wood pecker off in the distance outside, but I am sure it is coming from my PCs. I did the normal trial by disconnecting case fans to determine it is the cooling fan on the CPU cooler that is making the noise. Will try replacing the fan on one PC with another 120MM fan and see how that goes.

Pros:1) 0% thermal throttling on 7800x3d, Thermalright AM5 contact frame and PTM9750 in benchmarks. I haven't seen temperatures above 80C yet. Very important.2) One of the best coolers of this height from my research. 6 nice heat pipes, super polished base.3) Worked well with Asrock B650E PG-iTX mini-ITX and Gskill Ripjaws S5, even got some space left.4) Price. Just wow, miles cheaper than the rest.Cons (sort of):1) Fan noise can get somewhat loud (not very annoying, low pitched noise, just loud), when it rapidly spins up to high RPM, so I modified the curve to be more aggressive on lower temps, and it's fine. In games though, it's close to silent most of the time. Keep in mind, I think on an Intel machine with 120+W of sustained loads it would be much-much noisier.2) Had a bit of a hassle getting it fully aligned to fasten.

Basically this company just doesn't screw up. Buy their coolers. They are better if not the same and cost WAY less. Easy install. Not too loud. Perfect temps actually lower than expected. Not too big.

The cooling performance is great, it is keeping my 9800x3d cool at 90c with an all core 5.2 ghz overclock.I had to take off two stars because the stock fan is garbage. It is quiet but horribly balanced. The whole CPU cooler was vibrating harshly. Replacing this fan with a NC-A12-15 fixed the vibration entirely, no change in cooling performance. I just feared long term damage from the vibration directly over the CPU socket.-2 stars since I had to spend an additional 50% on a new fan. That said, I am keeping this and not returning it. Still a decent value and I wanted a low profile fan anyway. Just be aware, QC is poor and you may need a new fan too.
