Fan recommendation
 

Can you recommend a good, QUIET, 120x120 mm fan for radiator? I'm guessing 120x120x38 panaflo, maybe.

thanx

most fans are quiet when u run them at 7v =).....sunon all the way...panaflos are good too

i got myself several of these. you can also buy them from So-Trick Computers. these are nice if you dont have much space, since these are only 25mm wide.

first linky dont work

120x120x38mm 69cfm panaflo from caseetc

the link works perfectly fine for me. the site is FrozenCPU, the fan i linked to was the 120mm clear-bladed fan.

hmm works now...didnt work the first time gave me some kinda basket error

Thanks for all your input, I think I'll go with the 25mm clear fin fan, I already have one, so I'll make a sandwich and drop to 7v.

Food for thought question, anyone ever try using 4 super loud deltas on a black ice? I think 4x60mm would move a lot more air than one 120mm. Is this true?

the most powerful 60mm is the Delta 51cfm, while Delta make a 240cfm 120mm fan. so it's 204cfm at 8000rpm or 240cfm at 4100rpm.

I know I'd prefer the single 120mm. It'd have a higher static pressure too

might as well jus buy one of these and be done with it http://www.caseetc.com/cgi-bin/caseetc/F-400.html

Holy sweet Jesus! Fingertips dropping all over the place with that fan

Given the decibel ratings for fans, what range would you guys consider "quiet?" Sure, its subjective, but it might be helpful. Thanks

well if u scroll down they sell fan guards with that fan.....around 30db is usualy considered quiet...

Brad - the 4000rpm Delta 120mm is only 190cfm according to this.

Kibbler - to get a relative idea, go here. They've recording what the various fans sound like. Remember lower RPM fans at the same dBa rating tend to be much less annoying than the high RPM screamers. Remember also, dBa is a log scaled measurement, so a difference of 3 is TWICE as loud.

Haddy - actually that Rotron not only puts out more than the Delta, but is quieter too :) Even at 7V it would still put out in the 130CFM range.

yea i know now im gona have to make a shroud thats BIGGER then the bix...=D

erm... if you have 2 of the same fans running, do you consider it to be twice as loud as having one of those fans running? cause generally there is around a 3dBa difference between having 2 fans running and having 1, so by saying a difference of 3dBa is twice as loud, means that you think having 2 fans running is twice as loud as having 1 fan running... which i dint think it is.

i always thought 3dBa was about the smallest possible value where we could actually tell a difference in noise, wheras a difference of 10dBa is about a doubling in the noise we hear.

huh:confused: :confused: :confused:

actually, every increase of 3db is twice as loud. For example, 130 db is twice as loud as 127 db. Old autosound enthusiast here =]

i wasn't thinking of that fan, I was thinking of this thing http://www.deltaww.com/products/dcfans/triple.htm

my rpm and cfm were out (I was posting really late at night), but I think that's fairly irrelevant. Don't you agree? :P

3db = twice the power
twice as loud = 10 x the power
two equeal fans at the same distance from ear would be 3 db and twice as lound would equeal 10 fans
And this is kinda getting off topic:) The fans that come with the Swiftek Q-puwer case are real quite are just 25mm thick and can run at 5v or7v. I can't find my link to thier (fans) homepage or I would post it. "Mechatronics" is the brand name. But you can probably do no wrong with a Panaflow.

Brad - oh, THAT monster, that fan is 3" DEEP!! On the other point, yup, I agree, late night posting has it's affects ;)

Speaking of which... 3dBa difference is indeed a doubling of the sound intensity. But - the good ole human ear does indeed take a 10dB change in the intensity level before we perceive it as being twice as loud.

What a difference a word makes ;)

It's like 3x 120mm x 25mm thick fans in one. I bet it'd have a shit load of static pressure (like that on an 80mm heatsink will still be over 150cfm

LOL, yup :) At 4mm H20 static pressure it is still putting out about 190CFM. As a point of comparison, a Y.S. Tech 120mmx38mm 3000RPM fan has already dropped to 1/3rd of it's zero pressure rating.

But that monster of yours has a 59dBa noise level. In comparison the high end Delta 80mm is "only" 52dBa. You better not only have ear muffs, but lots of room too, lol.

the one with 184cfm, I'm sure that at 5v it'd be almost silent, and at like 90cfm

well after I did that automatic DD5 fan control mod, by soldering a DPDT relay switch. I don't have any noise issues with my Delta 130 CFM fans.
Actually I realized that it never switched to 12V from 7V in the last couple months. and that's a good thing.

I bought a Panaflo 120mm X 120mm X 38mm 86CFM from cooltechnica for my new chromie Xtreme Rev. 2
