Its quite possible, that the LP53's fins are so much better spaced / designed, that they make up for having less heat pipes.
Also possible that the LP53 simply has better heat pipes. LP53 fins also look to have a very similar arrangement as Noctua - and anything Noctua does is usually well researched.
The whole PC cooling business is a bit snake-oily - few companies stay clear of advertising stuff that sounds great on paper, but has no real benefit when its installed. Or, like with Cryorig, their manufacturing may just not be up to translating their concepts in the best possible way. (in more ways than just their posts placement being inaccurate - Thinking of Josh's complaints)
So, I may have been doing this for a long time, and I like to question and test opinions, but I'm still not completely resistant to advice and plain old data points from other people who already went to the trouble of testing.
So I'll start with the LP53 and the Noctua A9x14 fan - with a big thanks to everyone here!
@Thehack I'd happily buy this stuff from your store, but you're across the great ocean. It would take forever to get here and cause nothing but problems with waiting for customs, paying extra shipping/VAT... its horrible...
