A better question maybe is: Is the Thermalright FC-140 cooler reliable and a good product? Thanks
Hmm... Good product, yes.
Reliable? Ehh, probably not as good as Noctua. Noctua's products go through more QC checks, so as a customer, you would be less likely to run into 'hiccups', but they're not impossible.
Noctua has like a couple variations of some of their coolers, whereas Thermalright has a number of lookalike variants with slight differences - I'm not sure why. Maybe doing LED and non-LED caused all that?
Like, I see a Frost Commander, Frost Spirit, Frost Spirit V3... What happened to V2?!
They might even have a SE version coming at some point, like how the Phantom Spirit and Peerless Assassin have SEs.
Noctua has NH-D15(S), NH-U12(Redux), NH-L12S(Ghost S1), and that's about it.
For some, the high cost of Noctua's coolers is going to be a hard sell when they can get one that performs similarly for around half the price. So what if the fans might not run as long or they can get a little louder - the upfront savings makes it well worth it to them.
I have a hard time recommending Noctua coolers, and I used to be a Noctua fanboy...
The NH-D15S is Noctua's current best - from a price to performance standpoint - IF it fits in one's case. Their other coolers get poorer in value, particularly their downdraft models.
Even then, Thermalright has their Silver Soul 135(not the 110) for well over 50% cheaper than the D15S. Geezus...
Sorry for long post. Part of your question wasn't quite that simple.
