I will need to check about "LN and ULN 3pin adapter that are resistors to slower the fans." cos I have no idea about that, I've only seen classic 3 pin ones so far. I guess thats for hardware fan control? but whats the point? I can control my current CPU fan easy with Speedfan with a click. Right now its at 100% and it's running at 2437 RPM. Will I notice a big difference from this to the Noctua D14 at 100% too?
I can't go lower than 100% with my current fan or else Speedfan flame icon starts showing up at Core0 (it gets at around 41C). In the winter there shouldn't be a problem, but I would like decent cooling all year long with near total silence at least during idle so I guess its time to upgrade.
First i will suggest you to check the SPCR review on it, Noctua NH-D14 flagship dual-fan CPU cooler
you will find a lot more info there. About the it bieng run at 100% end up quieter... probably, the fans that come with the NH-D14 will not spin as high as your current 2400rpm, if i remember correctly i think the most they reach is 1300rpm, but even then with the massive amount of heat dissipation area of the NH-D14 and twin fans, you should get lower temps at a lower noise, personally i like to run my fans below 1000rpm, so i would still adjust them via speed fan or with the resistors (what ever you like).
I think i'll get the Noctua NH-D14 if it deliver the best silence/performace on the market, im not worried about money plus Noctua seems like a solid brand. What worries me is that if by the time I chose to upgrade the rest of the computer, a new MB socket is out that isn't compatible with the Noctua NH-D14, that would suck.
The cooler has been out for more than 3 years now, and as you seen there have been updates on the mounting mechanism and still sells fine. Unless mobos design change radically i think you should be able to move on with the cooler to newer setups, also noctua is said (i never have tried) to give free mounting upgradaes for newer platforms. Noctua will most likely keep on updating their mobo compatibility chart so before you upgrade your mobo, do the same and check it before buying.
About 12-7-5 I cant feel any changes. Maybe the background noise is too much, plus the CPU fan noise is too heavy to notice subtleties.
If you cant hear it, you still should be able to feel it, place your hand on the back of the case near where the exhaust 140mm is, and with your other hand switch the fan controller inside the door, see if you fan feel more or less air when you move the switches, else you don't have the fans connected to the fan controller. Btw if you go with the Super flower 500 W passive PSU, i would probably add an extra Fractal 140mm fan to the front so you create positive pressure and ensure the PSU will act as an exhaust, helping it cool itself by the air that will move through it.
This is the model that you will most likely find available in Europe, JonnyGuru Reviews - Super Flower Golden Silent 500W Fanless
. Upon searching more it seems kingwin does have a distributor on spain,
