Best ever Fan

[Heatsinkguy]

Okay i want the QUIEST possible fan but still able to blow atleast 50-75 cfm and it MUST BE 80mm by 80mm by 25mm. I just returned my Tornaods because they didnt fit and were too noisy even on fan controller.
It is okay aslong as its under 28 db.

[archilochus]

Take a look at this fan.For a solid shaft of air it cant be beat.
And the dBA is low.Im considering putting one on my SP-94 HS.

[Heatsinkguy]

Woaps i should have mentioned I NEED CASE FANS ONLY......

[archilochus]

If you go under 30dBA you will have very little air flow.Quite
fans are not capable of achieving CFM that you request.That
blower is an excellent case fan dood.:D Read up on it.
THE FANMAN:cool:REVIEW LINK (http://www.overclockers.com/tips461/index02.asp) :eek:

[Heatsinkguy]

But its a heatsink fan? i cant attach it to the case rite? what about the dynatron cross blower from http://www.dynatron-corp.com/products/coolingfan/coolingfan_model.asp?id=26&cid=30

[archilochus]

That makes a even better case fan.IMHO You get a longer or taller curtain of air thru the case.THE FANMAN:cool:

[Heatsinkguy]

But how do i attach that kind of a fan?

[archilochus]

There were some pics in that link.Go and read up on it.Then you
can help me by passing along the info.That way we help each other.You SEE! :D Thats a great find on the blower.Ive got to
go to work,back around 9:00 pm. THE FANMAN:cool:

[Heatsinkguy]

ughhh too lazy

[Heatsinkguy]

OMG...i went to that site and then i clicked on "Click here to discuss this in our forum" and then when i clicked on it UP CAME A FRIGGIN PORN SITE WTF Y0Y0

[archilochus]

BY the BY that blower is 38dBA.Might be to loud for your requirements. Keep your flow up & temps down!

SEE at the bottom of the page.:eek:

[mccoyn]

All the linked fans are under 20 CFM. True 3 of them might make a quiet solution...

[Heatsinkguy]

It says after i put the dynatron in, then dismantle all other case fans because i dont need them? The funny thing is they put the dynatron on top of a floppy drive and said "Cooler hardrive"

This is a very difficult request, 50-75cfm on a 80x80x25mm fan that is quiet is just like asking for Pop Rocks that dont pop.

This is a quiet (or a helluva lot quieter than a tornado) high quality fan and the vendor I personally recommend. This fan should last you for years.

The quietest high quality Papst I could find is this:
19CFM at 12dBA (the downside is all the above fans are dual ball bearing, and this Papst is a Sleave bearing with a 40,000 MTBF (which is roughly 4.5 years at continual use, the Sanyo Denkis above will last 6.8 years operating 24/7/365 )

I cant beleive no one has said that! It does 50-75 CFM, and its really quiet for the amount of airflow it pushes, yea it gets kinda loud at 75cfm, but its certainly pretty quiet for a 75cfm fan. It is 80X80X25

12th one down.

Thermaltake SMART CASE FAN II. Variable Fan Speed Control, by temperature sensor. Fan Dimension: 80x80x25 mm. Two Ball Bearing. 3-Pin. FAN Speed Control Setting: 1300 rpm at 20°C~ . 4800 rpm at 55°C. Air Flow: 20.55 CFM at 1300rpm. 75.7 CFM at 4800rpm.

It comes with a rheostat and auto fan speed control and its own grille.

http://images10.newegg.com/productimage/35-999-111-05.JPG

Here is the fan and the grille. Trust me, it comes with alot more.
Also you can control it yourself from I think 1300 RPM at not even audible and 20 CFM all the way to 4800 and 75CFM, and not quite hairdryer. This fan has one of the better airflow to noiuse ratio's

Good Luck!
-@0C

PS. I think it has a great airflow to noise ratio becuase the leading edge if the blade is perpendicular to the trailing edge and they are all aerodynamically shaped and all.

THE FANMAN:cool:FAN LINK (http://www.svc.com/comaaeseblfa1.html) :D

I use two of these as exhaust fans in conjunction with a Vantec fan controller in a Chieftec Dragon They seem to work extremely well, at least compared to the two Panaflo M1A's and two blue quad-LED fans I've previously used in that application, while running very quietly. The fact that they look so cool doesn't hurt, either :-)

[Heatsinkguy]

First of all how the heck do u attach these jet thingys? Secondly if it acts as a exhuast...where does it get its air to exhaust from because ths shroud thingy is covering the fan?

[gustav]

i'm considering the cooler master blue LED case fans. they run at 2500rpm, push 32CFM of air and are rated at 25db each. i would consider these fans mentioned here, for their awsome air flow, but i want fans with LED's, or at the least clear or a colored fan. thermal take's are nice in that you can adjust the speed, and they're orange. might consider them. i'm in the market for new fans too, and i have a case with a side window, so i dont want boring black fans, i want something exciting!

[blkgti]

The case fan mounts have stand-offs designed to fit the screw holes in the fans. As it happens, the screw holes in the Aero's are tight enough to hold them in place.

Secondly if it acts as a exhuast...where does it get its air to exhaust from because ths shroud thingy is covering the fan?

The fans are mounted to pull air from the side of the case, ie. the air escaping after being pushed through the HS by the 92mm H1A. The case temps never go above 28C under load.

[Heatsinkguy]

Urmmmm....i DONT NEED A HEATSINK FAN......lol
My stock heatsink works AWSOMELY...i just want to know how it will will take the exhaust air from?

I guess I should be laughing, too, as I don't recall recommending one.

[b[My stock heatsink works AWSOMELY...i just want to know how it will will take the exhaust air from? [/B]

That question was answered in my previous post:

"The fans are mounted to pull air from the side of the case, ie. the air escaping after being pushed through the HS by the 92mm H1A. The case temps never go above 28C under load."

Good luck!

[Heatsinkguy]

Oh i got it lol.sorry for the caps and missunderstanding. Are you absolutly sure they are quiet and push enuff air than the fans recomened here? Because i cant afford to rma again

No problem.

While the Aero's are extremely quiet when attenuated by a fan controller, I wouldn't recommend them to you. I have two reasons for saying that. First, I don't know what it is that you hope to achieve. Second, as stated in the original post, I don't think that your goal is realistic and, as such, cannot be met by any product that I'm aware of.

If you don't mind my asking, why do you feel that you need that much airflow? Even taking relatively low output fans, the air is exchanged several times per minute in a 2.5-3 cubic foot case.

In terms of my own experience, I prefer the airflow to noise ratio of Panaflo fans. I have not tried every fan out there, including the Sanyo Denki's mentioned in this thread, which indeed look very interesting. I have tried the SF2 and would not recommend it to anybody, no matter what its specs may be. HTH

[Heatsinkguy]

why wont u recomend the sf2?
whats the BEST DAMMMEST fan u ever used that gives a good ratio?

[blkgti]

Originally posted by Heatsinkguy

I don't recommend the SF2, because I don't think its cfm rating is justified, and, because it's sound is annoyingly high in pitch. Basically, a 80mm Panaflo U1A achieved the same cooling in my rig (mounted on the HS) as the SF2 without the noise penalty. Not that the U1A is quiet, but it's sound is relatively low in frequency without the SF2's grating whine.

I don't know how to answer that question for the reasons I cited in my previous post.

[bchur83]

I would get the SF 2. That way you have the best of both worlds, quiet and lower cfm, or louder and high cfm, and everything in between. I love my SF II's, I can choose how loud they are and how much air flow. I would recommend them just for variety of choices.

[shiyan]

No 80mm x 80mm x 25mm fan will ever give you 80cfm at 28db. The air movement itself will probably cause more noise than 28db, not to mention the noise from the fan's motor itself.

if you want high CFM for low noise, you'll have to get bigger fans. 12cm ones, that spin at low speeds.

The Smartfan 2 begins to get annoyingly loud at 74cfm.

Why do you need so much case airflow anyway? I thought you said that your current CPU temps are very low... why add noise?

if you have as many as 7 fan intakes, you definitely don't need 80cfm from each fan. with that many fans, if you set them up properly, you can let them all spin at something like 1500rpm, and your case temps won't be much different from ambient.

I'd say get some good quality case fans like Silversinksam suggested, the Sanyo Dekis, or the Papst.

He said Quiet

That fans dBA is up to 48 dB at 4800 rpm, He just got rid of a hairdryer Fan. And those temp sensors are terrible as they range of temps make them next to useless. Most people short the temp probe to make them run at Max rpm and then hook them up to a fan controller . Reason is the fan runs at 20cfm due to the temp probe range being unrealistic to real conditions and temps in the case. ;)



Fan Speed Auto Control Setting: 1300rpm at 20 ºc 4800rpm at
55 ºc

[Heatsinkguy]

I also want a fan that can be hooked up to the hardcanoe lol. Temp controll fans are HORRIBLE I HATE IT.
Can the SF2 be connected to the hardcanoe?

Actually, i used to have an old smt fan 2, yes it had that high pitched whine that drove me nuts. It also went up to like 5900 RPM. But the whine was always there. I got a new one and sadly it only goes up to 4800, but, this one has NO whine. Its a muted hairdryer at 4800 rpm, but what isnt? Using the rheostat ( this fan comes with an auto temp controller and a manual controller) I set it at about 3000 rpm and it is really quiet. As for this new 2003 fan vs the old 2002 one, ill go find a link to my old thread. Or actually ill just quote my post for other reasons.

well, my old smart fan 2 on top of my volcano9 died the other day. The date printed on it was September 2002. So, i had to take the whole HSF unit to get replaced, they did it, and i noticed sevral upgrades made to both the smt fan 2 and the Volcano 9 heat sink. First, the new smart fan 2 had a date of March 2003, one thing i noticed that could differentiate this unit from the old one is by the screw holes it is slightly indented or hollowed out. That isnt the big change i noticed though, it seemed to not have the usuall smart fan 2 whine, the old one you could always hear a distinctive "eerrrrrrrrrrrrrrrrrrrrrr" even at the lowest speed, this one is totally silent at the lowest speed, and at 4800 RPM, is much more silent than the old one at 4800, and seems to just make the noise of the air, and you can barely hear the "eeerrrrrrrrrrrr" so it seems more like a panaflow to me, but one problem with this fan, i think the motor is less powerful becuase it only tops out at the 4800 rpm @ 75cfm. It used to go to 6000 RPM @ an estimated by me 85-90ish cfm.

The Volcano 9 heatsink, still has the same rough bottem that you can file your nails on, BUT the old one the copper core at the bottem, whent all the way though and the aluminum part was build AROUND it, but with this new one, it dosent go all the way through, so the aluminum peice (fins, base) goes not only around it but on top, so the top of the copper disk is covered by the aluminum section, this lowered my temps quite a bit.

well, anyways, just an FYI on some improvements that they made

Cheers!

:)


SSS, yes this fan can get noisy, but I beleive that it has a good airflow to noise ratio the same or better than a panaflow. And where did you find that link? Ive been looking all over TT's website. Huh my 0 feedback rating of their site design must have urged them to put in a link to their fans.

The smt fan 2 moves 1.6 CFM per one decible at max speed and 1.2 CFM per one decible at its lowest speed ( i think thats not accurate and its quieter than what they say, the old one yes, this new one without the whine, its definatly quieter, but ill just do this according to TT's specifications.)

The panaflo that has these specs,

Dimensions: 80x80x25 mm
Air Flow: 24 CFM
Speed: 2450 RPM
Noise: 28 dBA (Ultra Quiet)
Voltage: 12 VDC
Current: 0.10 A

has .85 CFM per one decible.

Dosent this clearly show that the smt fan 2 owns even a silent panaflow?

I bought my SF2 about three months ago. If the old version was even worse, I have a hard time imagining how anyone could remain in the same room with it. Even turned down to ~3,000rpm, I could still hear the SF2's never-ending whine over everything else.

No, it shows that it's absolutely ludicrous to rely on posted specs to make a determination of goodness. We want good cooling performance coupled to a reasonable noise level, correct? In my system, configured exactly as it sits in my sig, the SF2 cooled the CPU no better than the Panaflo. Given this event, one can arrive at several possibilities to explain it: 1. The SF2's specs are grossly overstated, 2. The Panaflo's specs are very conservative, 3. The two fans have different flow dynamics with the Panaflo's being more compatible with the SLK-900 and the SK-7, which were used with both fans.

Perhaps it's even a combination of all three. That said, all of it irrelevant since the end result - their cooling performance - was virtually identical, and the Panflo's noise characteristics were a lot more tolerable.

[Heatsinkguy]

so the panaflo is better? if so where can i buy them?
I need 7 of them with fast shipping. Also i HOPE ur friggin rite because i dont want to return them cuz i HATE IT.

[@md0Cer]

Well, you definatly wont have to worry about noise with the panaflow, but you wont get nearly as much airflow. So if your not worried about airflow and just want quiet, get the panaflow (keep in mind youll need to get a little power connector becuase the wires on panaflo's are bare at the ends). But if you need high airflow you might want to take a chance and get the smt fan 2. But you may also want to reconsider becuase ive had one smart fan 2 that drove me nuts and one thats extremely quiet, so you dont want to end up with 6 quiet ones and get 1 loud one, then you will be screwed.

[Heatsinkguy]

Hmmm hell no iam not getting panaflow if it has bare ends...now my choice are down to sf2. Any other options?

[blkgti]

Yes, I think it's better than the SF2. You can buy them in almost any online store: Directron, SVC, FrozenCPU, Newegg, etc. The Sanyo Denki's mentioned elsewhere in this thread seem like fine fans, too, but I've yet to try them.

I need 7 of them with fast shipping. Also i HOPE ur friggin rite because i dont want to return them cuz i HATE IT.

Please don't buy anything just because I recommended it :-). Do your own legwork and you'll be much happier for it in the long run. As you're planning on using seven of them, you may want to consider using the M1A's or even the L1A's, the latter of which are almost inaudible.

[@md0Cer]

hmmm none that I can think of. Really if quietness means alot you would really be taking a chance with the smart fan 2 as i said. I really wouldnt want you to be disapointed and also that would really **** me off if i got all quiet fans and one whined. I hear multiple stories of people who get quiet ones and people who get loud ones. Im gonna go searching for some nice quiet 80X80X25 fans for ya. Ill be back.

I agree. I remember there was one site where you could listen to the fans. Im gonna go search for it. That might help you out a little.

Almost every site that sell them either includes a terminated tail free of charge, or for a buck or two extra.

I'm hardly an expert, I've just tried a bunch of different fans and you can easily do the same. As you need so many of them, why not buy a 2-fan batches of various kinds of fans and see which you like best for yourself?

[Heatsinkguy]

Thxxxx alot man

LOL TT wont be a choice....The Enermax REALLY was good and so was the Sunon and the Vantec Stealth was EVEN better. I might get Vantec Stealth

[@md0Cer]

Oohh looks like that enermax one is even better than the smt fan 2 in cfm to noise. If you got something to turn it to whatever RPM you liked the best. But the vantec stealth is a good choice.

and now i just got the urge to post something at the bottem in bold............

im j/k lol :D

[Ven0m]

Check Evercool (both alu and led ones) and Noiseblocker fans.
Evercool has lots of cool alu fans, their led fans run L: 25cfm@23dB, M: 32@25, H: 37@27, Noiseblocker has for example( that's what they say) 80s running 30cfm @19dB or 44cfm @ 32dB.
