I see. Well as I was saying when it comes to fans and I can only speak for myself. Take every reviews out there with a pinch of salt, and what everyone else is saying like " Go with X brand cause they do X better than X but if you compare X vs X then I would say X has the upper hand "
The best review out there is yourself. Thats what I did down the line. I listen to what ppl say, I did read reviews but in the end I just went: " F... this, I am going with this brand and testing it out at MY home not in a darn lab setup " Then I saved up some money, swapped the fans out for some brand that most ppl say is the best. Guess what... they where not the best at my home in both keeping the temps dont or the noise. But for me the "safe" bets are:
Ek-Vardar, Noctua ( the industrial series ) , Be Quiet!, Noiseblocker Eloop. These 4 brands is for ME good, at MY home with MY system with MY ambient temps with MY ears. ( get the picture
So I am not going to sit here and say: The brand X is pure BS and you do best to just stay far away from them, cause in the end, it could be just that brand that is just perfect for YOU.
Just go for a fan that has high static pressure that we all can agree on unless you go for a radiator that has 9 FPI.
And just test, find out.
Do you have a 280 radiator laying around of maybe one of your friends do? or even a 140 radiator? Buy 1 or 2 fans and try it on, test. Like it? then go buy all the fans you need for your complete system
Really the best advice I can give, but I am again no fan expert, but only sharing my experience. But if you ask me.. If we all had the same ears and the same taste, there would only be 1 fan brand out there. There is a reason it aint. Same with everything else there is to buy out there
