Quiet Static Pressure Fans?

post #1 of 12
Thread Starter 
Hi Guys,

i've got a AIR 540 Case and bought 3 Noiseblocker NB eLoop B12-PS a while ago and their PERFECT they run on 10% no matter what but sadly i just can use them at my top 240mm Rad (of just 2 of them lel) because i cant use them in the front, because the eLoop's get really loud when something is in front of them.
Thats why i used 3x Noiserblocker Ulta Quiet XL1 Fans connected to a Molex -> 5v 3Pin Adapter on my 360mm and their were so loud that i want to change them and no longer use them. (Their over 5 yrs old maybe their broken i dont know)

Currently the Space between my Fans and the mash is like 3mm so i quess i should grab like Corsairs SP 120 Silent but what do u guys think? Im Really picky with noise.

Thanks guys

I didn't find the Corsair SP120 that quiet. I had 5 of them and ran them for a few months. I replaced them with all Noctuas, which were more expensive, but much quieter. I would recommend a Noctua variety.

The newest fan I am giving a shot is the Thermalright TY141. I find that just as quiet as the Noctuas, but the sound is even more pleasant. Unfortunately, due to it's shape is probably not ideal for a radiator.

You could also try to mod you case by cutting out some of the grill. My grills were behind a removable mesh cover. I cut out all the grills and the mesh cover hid my hack job. The result was a lot less air turbulence noise.

End of the day, Noctuas are always a good choice. Not the cheapest, not the best I'm sure, but always really good.

Arctic F12's for cheap, decently effective and quiet. EK Vardars have been tested to be among the very best along with Gentle Typhoons if you can find them.

My apologies I answered a bit hastily earlier and didnt notice your requirement for such a low pwm level. At lower then 1000 rpm AFAIK according to Martins liquid lab testing theres little point worrying about static pressure or getting the best fans, they mostly perform similarly. Just get something you like the look of that will limbo as low as you want it with a tone you like. Cougars perhaps? I use Noiseblockers and get the same whine you talk about, GTs are better but are obviously voltage controlled, Gelid silent 12s are the quietest ive used, but I used the non pwm ones. They are toltally silent to me but I have a feeling youre a lot more sensitive to noise then me smile.gif

i love this forum so fast and usefull answers smile.gif

will check your link @Slink3Slyde: tomorrow smile.gif

i cant even tell which part is "loud" my alphacool d5 pump is running at the lowest level (1) and my psu has a 0db mode and currently just 2 fans are running (nb eloops) and they run at ~400-500 rpm

:c im just to picky

btw: is it even possible to turn fans off via software? does it depend on the fan? i guess not

AFAIK ONly way to turn fans off completely is to cut the voltage, so Im afraid not, unless you have a fan controller wih an off switch. Someone else might have a suggestion yet smile.gif

I've spent a lot of money on fans based on recommendations and reviews only to be disappointed. I now buy 1 first to see if I like it. If I do, then I buy the rest. Might be worth being cautious if you're unsure.

Why get the Vardar f4 when you are going to use them at as low as possible? Id go for the f1 at 1150rpm. I can tell you that the Gelid Silent 12s I mentioned are the quitest fans Ive used out quite a few models, 120 and140 they used to be fairly cheap as well smile.gif

Fair point above to is it possible for you to order 1 of a couple models and return the ones you dont like ?
