Thermalright today introduced the Peerless Assassin 120 MINI series of medium-sized dual fin-stack CPU coolers, which come in two trims—all black and all white. As its name suggests, this is a compacted variant of the Peerless Assassin 120 cooler from 2021. Its design involves not just a smaller heatsink, but also a single fan configuration, with a single 120 mm fan located between the two fin-stacks, pulling air from one of the stacks, and pushing it through the next. With its fan in place, the Peerless Assassin 120 MINI measures 125 mm x 110 mm x 145 mm (WxDxH), with 135 mm height without the fan. For comparison, original Peerless Assassin 120 measures 125 mm x 135 mm x 157 mm, and has a dual 120 mm push-pull fan setup. Including the fan, the Peerless Assassin 120 MINI weighs 820 g.

The design of the Peerless Assassin 120 MINI involves a nickel plated C1100 copper base, through which six 6 mm-thick copper heatpipes pass, with the two aluminium fin-stacks along their two ends. The included Thermalright TL-D12B fan features a fluid dynamic bearing, turns at speeds of up to 1,500 RPM, pushing up to 66.87 CFM of airflow, at 1.53 mm H₂O static pressure, and 25.6 dBA maximum noise. Among the CPU socket types supported by the cooler are LGA1700, AM5, AM4, and LGA1200. The company didn't reveal pricing.

A 120 mm dual tower is now considered "MINI"? What's going on? :wtf:

So......SS135 but with a tiny bit more finstack area? TR doesn't seem to believe that this cooler will perform any better than its 3(?) year old predecessor.

It's 135mm height so quite a bit shorter than your typical 155mm 120 tower. If they are reusing SS135 fan clips, then they are only designed for the special 120mm fans with trimmed corners, although you can still (painfully) stretch them to fit.

Typical 92mm tower is about 125mm tall. 135mm is the most that cases like the NCASE and Cerb could fit.

I wouldn't call a 135 mm tower "mini" anyway. My brother once had a Coolermaster TX3 with a 92 mm fan. That's way closer to the definition of "mini" in my books.

Except this isn't a bare minimum low-end 92mm tower. We could always go smaller, which is beside the point. This performance class is more comparable to something like a NH-U12S, but in a more compact package closer to a 92mm.

I don't know... it still sounds to me like calling the 14900 non-K the "14900 mini". :oops: Or the least expensive Ferrari the "Ferrari El Cheapo".

Relax, it's all relative. Mini Cooper is considered a not so huge automobile, yet it's hundreds of times bigger than 14 UK shoes, also considered king size.
I don't see a flaw in calling this a "Mini" as far as it's smaller than the original Peerless Assassin.

My problem is that the price is unknown. I'd purchase this thing if it's cheaper than the OG variant.

That height will allow it to fit into many mITX cases (like NR200) where the original would not.

I live in Russia so your prices are irrelevant for me... Will look out next month, hopefully will be reasonably priced.
