Seems like a very decent cooler.
120mm fan (non PWM) and pre-applied with Thermal Grizzly thermal paste (The page says violent bear but that's like machine translated, violent bear is thermal grizzly in Chinese)
6 heat pipes + nickel-plated base. Similar coolers are usually $100+
Up to 240 tdp cooling.
There's also another 92mm variant for smaller cases at a similar price.
HX6240: 120mm(L), 105mm(W), 162mm(H)
HX6210: 92mm(L), 92mm(W), 125mm(H)
There's also the beefy HX6250 with a 140mm fan for $69.
These look like pretty decent prices, though I'm not seeing many reviews.
