Thanks to Community Member CrazyHorse for sharing this deal.
Product Details:
Double-tower dual-fan cooler, which adopts an anodic frosted top cover + fully electroplated 6 heat pipes and Seiko micro-carved reflow soldering copper bottom process, combined with a 12cm high-performance blackened fan, which can give full play to the heat dissipation effect of the CPU cooler stably.
Leaves space for RAM, no matter how high the RAM is, it doesn't block the light output of the RAM, and there is no need to raise the front fan, thanks to the matching fans, the middle fan of the cooler is a standard 12cm cpu fan, and the front fan is a thinner 12cm fan, the thinner pc fan has a high RPM of 1800RPM, and the high airflow makes it easier to dissipate heat.
Dimensions: 122 x 114 x 155mm (4.8 x 4.49 x 6.1")
Heat Dissipation Material: Aluminum + Copper, All Aluminum Fins of the Main Tower, which can bring the maximum heat dissipation area, and the S-FDB bearings attached to the dual fans have a long service life to ensure the service life of air cooling and heat dissipation.
Dual fans attached to the heat dissipation are TL-C12B V2 and TL-C12015B, with fan parameters of 120 x 120 x 25mm/120 x 120 x 15mm, speed of 1500RPM+10%/1800RPM+10%, air pressure of 1.53/1.24MM H2O, air volume of 66.17/59CFM, operating noise<25.6/26.1DB (A), fan interface: 4PIN PWM, voltage: DC 12V
Compatible with:
Intel: LGA115X/1200/1700/1851
AMD: AM4/AM5
Includes corresponding mounting grommets for easy installation, which can be installed according to the instruction manual or the installation video
Note: For AMD installation, you need to use the original motherboard backplane for installation

This is pretty solid for the price if going with a more efficient CPU like a lot of the Ryzen chips that don't necessarily need the cooling power of the Peerless and want to save ~$15 or so (Peerless usually goes on sale for around $35). Can also cool many of the more power hungry chips if not overclocking and don't mind the increase in fan noise (I have an air purifier running at all times that is louder than my PC's fans to put it into perspective).
If you're going for a higher wattage chip or boosting clocks, I'd probably still go for the Peerless, but something like the 9600X should do fine with this (overkill honestly). Looks like it can cool up to 222W effectively, which is low for a dual tower but probably more than enough for a lot of chips: https://www.tomshardware.com/pc-c...-se-review
They really shouldn't have cheaped out so much on the fans but at $20 I can't really complain. At MSRP it sucks though. Just overall an odd double tower cooler that's overkill for lower wattage CPUs where a single tower would work, but then a bit weak for higher wattage ones.
These $20 6-pipe air coolers can perform as good as 240mm water coolers and at par with some of the 360mm water coolers. And they don't clog up or fail like water coolers. And they're a lot cheaper.

There is something to be said for leaving meat on the bone (fan-wise) because a person who buys this could very easily upgrade the fans later down the line without needing to completely replace the heatsink and repaste etc.
For sure the Peerless is a better deal right now, since it's in the $30 range. For $20 though this is a great deal.
This is great price if you want a dual tower that doesn't block the RAM. Very similar to Scythe Fuma.
I tried this cooler but it felt more of a side grade compared to my Burst Assassin two fan set up. It was about 2-3 degrees cooler with the Royal Knight. My CPU is 5700x3D.

From what I can gather, it appears Thermalright's coolers are the new Cooler Master Hyper 212s just to boil it down for simplicity's sake. Correct me if I'm wrong.
Solid deal, around this price you rarely see dual tower coolers. If you really need the extra cooling you can pick up a full-size front fan and replace the smaller one here but that would remove the main selling point which is RAM compatibility. Though I doubt a higher CFM fan (like the C12C on the PA120SE) would make a difference in most gaming scenarios. 8 core chips like 7800X3D/9800X3D and under will be totally fine with this cooler.

Even on sale, the Peerless assassin over double this price. The Thermalright is enough cooling for all but the top 5%.
And let's be real. All you top 5% tweakers are buying the Arctic 360mm AIO anyway. 🤣
This looks like it would be much better than the NH-U12S with the second fan. The one cooling tower on it and 4 heatpipes made my 5950X run extremely hot, as in 95C hot.
That said just today I replaced my second Thermalright 360mm AIO due to pump failure for the peerless assassin 140mm. While not as good as the AIO (when it works) its real close, and now I don't have to replace it if a pump dies. The hottest I can get it with a decent fan curve is 73C.
I also put the same peerless 140 on a 5700X and can't get that above 65C in a more restricted case. If I had known I'd have just bought this instead and saved $20. 65W CPUs don't need the peerless.

The PA is $32.50, ~50%more than the OP, and it was that price for months.
