yes becuase everyone wants and has room for 2 x 120mm aio cooling solutions.
No, they are noisey and not as efficient as air coolers they have parts that will run out the metal fins on normal air coolers will never suddenly fail after a power surge and will more than likely fit in your next case and the case after that.
Large premium air coolers are a long term investment and thats why people spend the cash on the premium models. Like the silver arrow and the nh D series.
Noctua is also one of the only brands that supports every socket in existence and will also send you free of charge new fittings to fit newer chipsets if the dimensions change provided you can show proof of purchase.
And their fans despite the colour are among some of the better ones in the market.
So Yeah I have no idea why people would trust this brand and buy into it even at the best part of 80 quid.
