Aluminum 120's...

[Eklipto]

Any particular reason these are so popular to use with water cooling? Obviously they go on the radiator, but what makes them so different than a normal 120mm?

 

[miro]

i use them cause they're so purdy.
they actually have a pretty good airflow-noise ratio too.

 

[Eklipto]

So primarily for cosmetics?

Can anyone vouch for the performance?

 

[Senater_Cache]

They suck.
They are so very popular because so little people know what to look for in a Heatercore fan.

First off, they are NOT as quiet as one might think. I doubt Evercool has proper dba measuring equipment, as these fans are louder than my ANTEC 80mms whcih have a higher dba output.

Second, sure they have a "high" CFM rating of 80, but they have very unnattractive pressure specification. I dont recall the actual rating but it isnt what one should be looking for in a US style 2" thick Heatercore scenario.

dont waste your money.
I recommend Sanyo Denkis or Nexxus.

Whoa! Way to put it bluntly. After this post I am afraid I'll have to hear some more opinions on these fans. Cause if this post is in anyway true I dont know why so many people would be using these fans..

Btw, are all the aluminum fans I see Evercool brand?

 

[RickyJ]

The Evercool aluminum fans are made by AOC (Alpha and Omega Computer). AOC is stamped on each fan, and AOC's site lists these fans saying they're for Evercool only. AOC lists the 2200rpm 120mm's at 31dB.

Either way, I've got 2 of them mounted on my Bonneville rad. At full voltage they're not that much better than my old Aeroflow (38dB) was, but a lot of noise is from the air rushing through my rad. At 7V they're a LOT quieter (bit quieter than my Aeroflow at 7V), but not as silent as I'd like. Overall, I'm happy with them, but if I could find some quieter and better plastic fans I'd run those instead.

The problem is that few axial fans can output the static pressure to push very much air through a thick radiator. The thicker the fan, however, the more pressure can be put out by the fan. Any 38mm fan will be better than a 25mm as far as noise/pressure is concerned.

I think I covered in my first post why that is.

and to add to the first post....
maybe the people who are using then (like me) were/are persuaded by the high dba to cfm ratio.
after all on of the most popular reason to watercool is noise reduction.
is it not?

to defend my first post however I must say that these Evercool / AOC fans are not representative of their dba rating in comparison to more respectabel companies' dba ratings (ANTEC) when directly compared (using no scientific equipment, just my eras)

 

[DieLate]

Now that you've rulled those out, does anyone have any experience with these:
http://www.newegg.com/app/ViewProductDesc.asp?description=11-999-012&depa=0

Enermax 120mm rated at:
24.6 - 30.1 dB
63 - 95 CFM

The stats sound very good, but do they live up?

I appreciate your input....but I'm running one Evercool 120mm aluminum fan on my DTek Pro Heatercore, and it's set up with a shroud to suck off the rad, and it's the only radiator fan. If the fan is so horrible then explain to me why I can clock my 2.8C at 3.5GHz with 1.75v and still pull off an idle temp of 23C, and a max load temp of 30C.

Obviously the fan is working for me, so I can experience here and tell people that it's NOT as bad as Senater_Cache is making it out to sound....not even close.

 

[RickyJ]

Leaving your window open, Cornelious?
What are you using to measure your temps?

BTW: I've got a fairly quiet burner (I've heard WAY louder ones before) and these fans at 7V are a lot quieter. I'm curious about how much quieter a pair of L1A's would be, or how much better they'd cool. I could spring for a $70CDN dB meter from Radio Shack, but I'd rather put the money elsewhere.

you need to think more 'objectively'
just cause you can obtain a nice temp doesn't make your fan the best performer for the price (or even a good performer, in that case). Any 25mm fan won't be able to pull the same amount of air per RPM (depending on blade design and other factors, of course) through the rad becasue of the restrictiveness of the fins.
He's just saying there is better stuff out there, and.. there is

thx...
to add they are 25mm they wont push crap trhu the rad...

There may very well be better stuff out there.....but the comments like this that you guys are making are kinda coming from out in left field...and you're making yourselves look a little ignorant. To simply say that all 25mm fans are $hit and aren't gonna be able to push/pull enough air is ridiculous. There sure are some really nice 38mm fans out there, but for the amount of people that use and recommend certain 25mm fans you'd think that there's SOMEthing that's working for them.

I'm not going to sit here any argue about this if you're just going to come back and say that 25mm fans are garbage again, because I don't need to use up my time beating against the wall like like that.....sorry.

You can have your opinions, and that's fine.....but when you make someone else's look like crap you more or less lose any credibility that you might have had. I'm not denying the fact that 38mm fans are better, I'm denying the fact that ALL 25mm fans are garbage for heatercores, because they're not....and it's too bad that you're being that naive about it.

 

[thelostrican]

cornelious0_0: go here educate yourself like i try to do.

the aluminium fans in questions are in there own way great and they are ok, overrated, but ok. but the fact is that 25mm fans have less static pressure, and cant push air thru the rad as good as a 38mm fan in general. there are no and's if's or but's. thats just the way it is, and although they might and are perfectly fine for use in a blowhole or a heatsink, they just plainly suck at pushing air thru any kind of resistance(radiator). as a matter of fact and menioned by people like cathar, billa and many other that do know what they are talking about, dc fans in general are really bad in general for the use we give them in pushing air thru a rad.

i certainly wasnt trying to put somebody down, or anything like that.

would you prefer that people trying to achieve a perfect setup, might it be a silent one or powerfull one, that dont have the knowledge, and are checking these forums, would buy 25mm fans thinking that is the best choice?
i certainly wouldnt.

 

[cornelious0_0]

No, I wouldn't either, but what's available for selection in 25mm fans will always keep them more popular. the only 38mm 120 fan I've got is a Delta that blows 190cfm and is bloody loud. I'd use IT, but I dont have a fan controller to throw it on, and I'm NOT leaving it running 24/7....at least i dont think so. I could maybe get used to it.....but I'd have to see. Right now with my 25mm aluminum fan my idle temps are only 2-3C above room temp....which is good enough for me, my max load does go up by 7 or 8 degrees though, so unless I would cut THAT back by a few degrees I'll just sitck with my 120x25.

I'm not ignorant towards any of this, and I'm willing to admit that my fan just isnt the greatest for this, but what I'd gain with my Delta isnt worth enough to me to put up with the noise....and I dont feel like picking up another fan right now....too many other things with my comp already on the go.

Truce?

 

[orkan]

I run these same fans. I have one of them sucking air through my JR-120 rad. Zero problems, and the noise doesn't bother me in the least.

I'd rather have this fan on there than one that pulls another couple CFM and looks like shit.

Hehe, yeah....I probly wouldn't replace it unless Evercool put out a 120x38mm version of it....cus I'm doin' a black/silver theme with my case and with the heatercore ontop of the case it goes: black case, silver heatercore, black shroud, silver fan.

You could probably 5v your delta, even though it wouldn't be pushing as many CFM, it'd overcome the restrictive nature of your rad a little better

Also: i assume youre measuring your temps with the mobo probe
2-3c above ambient isharder to achieve than one might think. especially if your heatercore is located INSIDE your case. (unless your case temp IS your ambient temp... )

i totally agree as far as 25mm they are probably the best thing around, a Delta is to freaking loud for me...lol

i like the sanyo denkis and the panaflos, the low ones l1a's.the beauty of the l1's for example is that while rated at less cfms as the evercools, they probably push more air thru the rad, while keeping the noise down, dont get me wrong though, my point was and i didnt express it, was that 38mm are a more efficient setup in this case, but the 25mm will do the job.

i dont have any windows or anything so i dont mind that the fans are ugly, and they are ugly, so if they are going to be seen thru a window, then the evercool would be a better choice.

truce? no, we never had a beef to begin with...just sharing information, i dont know it all,and neither do you, but together we can get a better understanding of things, and thats whats its all about...

p.d: if i came out like a jerk i apologize, its hard to express something in a forum, and english is not my frist language.....my intentions were not to sound like a jerk, and just having a normal conversation

Cool beans, and I do understand what you're saying about a 38mm fan rated at a lower cfm still being a tad more efficient. If I ever find room/a way to move the heatercore inside the case I'll pick up a Panaflo for the rad, but for now it's ontop and the Evercool looks much nicer.

 

[qbert95]

Im using a aluminum 120 on my heatercore and I think it runs fine. I have it hooked up to the fan only molex from my powersupply and it is inaudible and pushes decent air. It also looks much nicer than the other fans as others here pointed out.
