I am not interested in these brands. That's not at all my question.
Hey, if you're looking to get a fan other than the ones that come with the heatsink, & don't care about spending more $$$ to get less, well, that's your prerogative.
BTW... I didn't mention it before because I'm sure my experience is the exception
& not the norm, or at least I hope so. I suggested other brands because along with the high price of the Noctua fans, I've personally had 100% failure rate with Noctua fans. Two fans, both came with Noctua CPU heatsinks, one died after about 9 months use, the other around 11 months of use.
