best 120mm fans? (w/ specific requirements)

Ok, so you are all thinking this has been done to death.

BUT, what I am looking for are 120x120x25mm fans that are either no LED or green LED, quiet (well, not loud), must push at least 60cfm (preferably ~65-70, not much more), be able to be powered by either a fan header or molex (for now I need molex powered, but am getting a fan controller...) and finally the mounting must not be the Papst style (with platic running between each side where the holes are).

Also if there is a 120x120x38 version of them, thats good (for the new heatsink when it arrives).

So, what would you guys recommend?
 
Delta triple blade at SidewinderComputers

NMB SmartFan at bgmicro.com (this one has a thermal sensor - starts at 50CFM at .160A, bypass the sensor and it will go up to 118CFM at 0.74A - pretty quiet at below 7V. Scythe SFF21F or Scythe 120mm Fan DFS122512L - SB or the Zalman ZM-F3 at jab-tech.com. And there are a couple of Silverstone 120mm fans at Newegg et al.

Fans have open ears or closed ears. You want open ears,ie, no bits of plastic bridging the
area between the mounting holes. That is done BTW, to stiffen the frame for less resonance.
Or so they say 😉

The 1600 rpm Scythe S-Flex fan 120x25 drives 67cfm. It comes with all the connection types.
It is not cheap. It's a VG fan imho. It has small ears that will not get in the way of a HS mount
for the fan.

You do not need a 120x38 on a HS. If the sink took a 92mm fan maybe a 92x38 would be the
way to go.

For a case intake fan, the Sanyo Denki 120x38, 103cfm@39dBA, #109R1212H1011 is killer.
It will start/run in near silence @5V, driving 50cfm. It ramps up real sweet. I sold 18 and only
kept two out of a case of 20. Not one buyer complained. Bitchin fan!! Has a tach feed too.

The Delta EFB Triple Blade fans are worth a look. The spec listed by Delta is to be trusted.
They come in all sizes.

cheers guys. Now to find some of these fans in New Zealand....

Galvanized: what fan you using on the SI-128? Think I will stick with a 120x120x25.
 
The Scythe I spoke of above. It is a heavy fan. The NMB Zepper spoke of weighs 6oz, the Scythe S-Flex with ceramic bearings weighs 8.5oz.

Those NMB's are only $4 State-side.

Hey Vin,
. There you go, not reading the OP again... None of those make 60+ CFM...

Sorry! I was at work, and 'they' were calling me on the p.a.

I'm not retired, like some of the ppl here... 😉

 
Hey, wait a minute...

The Silent Wheel, and the Streamliners are pushing 55 cfm.

That's kind of splitting hairs, isn't it?

*edit*

Sheesh! Okay, no blue LEDs...

That leaves only the Thermaltake Silent Wheel.

*edit2*

But, wait, he said 120x120x25... That leaves nothing...

Picky, picky, picky! :laugh:

*edit3*

Hey, he said it's for a HSF -- so the Thermaltake is still in the running, yes?

That's what it's made for... it's a 'better' 120... a 130 in fact!
 
No that doesn`t leave the Thermaltake Silent Wheel.
I bought one and sent it back the next day.

It is very loud. Compared to fans that accurately list their true dba.
Thermaltake does not know the meaning of the word "silent".
Their quoted dba reading on all there fans are off by as much as 10-15 dba.

The Scythe X Flex is a very nice fan. I have one of those.
The Sanyo denki fans are right on.

Have fun.
 
Hey G-Y,

That's not a real-life price on the NMB. New retail would likely be over $15. US. Not many countries will have the post-silicon-bubble parts vultures we have here.

So, Thermaltake, et al, are a bunch of liars - or as Galvanized would say, "they don't know what the hell they're taking about!" 🙂

Good to know!

When you think about it, I don't know how anybody could make a 'silent' fan that pushes that much air. Fan noise is usually caused by the blades 'slapping' the air, i.e. the more air they move, the noiser they are. I learned this in 'ground school'. You wouldn't believe how noisey a 'fan' can be until you've ridden behind one at take-off!
