Hi guys!

What do you think about these fans? It looks good on paper. Is it on sale anywhere yet?

Update
I have found a review. It doesn't give much info about how quiet it is compared to the other fans. But, at least, there's plenty of pics and some interesting infos.

What do you guys think? Anyone planning to get one to test?

Interesting looking fan....fairly high airflow for 1200rpms....

Look at the way the reviewer mounted the thing, blowing into a very restrictive outlet. Now how could that setup be quiet?

the flow is pretty high because is a 38mm thick fan!
i would give it a try. the only problem is i dunno if/where is available in Australia...

any other reviews available? im definitely interested!

I wonder about the 80mm version.
It has an unusual fan blade design, and only spins at 1800 rpm at 12V. I wonder how well the "fan fault" protection works.

hmm... this does look interesting. We might finally find a decent 38mm thick fan.

atomidude · Post by **atomidude** » Sun Apr 03, 2005 11:17 pm

too bad the only review i've seen is not helping much. i would like to know how it behaves at 7.0V, if there's any motor noise when undervolted... google doesn't help much, it seems the fan is very new and most of the sites that have this fan listed are in Japanese

oh well, i guess we'll have to wait a bit. im quite excited, it could be one of the best 120mm fans ever, considering the CM fans are not too bad, is 38mm thick with pretty high air pressure and flow, and should work very quiet at 500-600rpm

Their LED rifle bearing fans were a pleasant surprise, I hope SPCR can get their hands on one of these to find out if they are as well! Note that they advertise using Japanese ball bearings.

i don't get it, the Cooler Master is a rebadged bisonic? the specs don't seem to match...

I don't know about that but the aluminium fan that I have (Primecooler) is very heavy.

Atomidude,

I'm not really sure what coolermaster is doing to arrive at 1200rpm, but you can have a fan maker customize certain specifications or it could be a 24v fan. The nexus 92 is made by dynatron, the same manufacturer of the top motor fans that antec uses. And the nexus 80 is made by bi-sonic and of course the nexus 120 is made by yate loon. - FG

there's one thing that's worrying me tho:
Input Power (Watt) 12.00 W (Max) 1.0A
my mobo manual saz a max of 0.6A on the cpu fan header... that's what i plan to use, is the only one that allows me to control the fan speed with speedfan.
do you think this would work?

frankgehry · Post by **frankgehry** » Tue Apr 05, 2005 8:13 am

A,

I would email coolermaster and find out about the amp rating. I have a 120x38 delta that's only .25 amp so somethings not right. - FG

Talz · Post by **Talz** » Tue Apr 05, 2005 10:54 am

I think it's supposed to be .1, 1 amp would be for some crazy fan at 10k or 15k rpms or something equally ridiculous like 200mm.

well, 1.0A could be right. my Evercool 120mmX25mm is rated max 0.4A at 2,200rpm

Elixer · Post by **Elixer** » Tue Apr 05, 2005 1:59 pm

On the fan itself it says 1.1A. I have a 24V fan from bisonic that is rated at .25A at 24V. 24V * .25A = 6W, yet when I looked up the specs it said it was a 3.25W fan. This leads me to suspect that bisonic may over-rate current on their fans. Perhaps they rate the fans based on some theoretical absolute worst case scenerio? I don't know. Normally fans are rated based on their stall current correct (ie when the fan is run at full voltage with something preventing the blades from moving)?

atomidude · Post by **atomidude** » Tue Apr 05, 2005 2:25 pm

here's a picture of the fan where you can see the rating:

Bluefront · Post by **Bluefront** » Tue Apr 05, 2005 2:34 pm

That 2.0A rating has to be a mis-print. I have a 120mm, 38mm thick, 12v IMC (NMB) Boxer Aluminum fan. It's rated at .2A. I can't imagine any fan made for a computer, to draw much more current.

I hope you guys considering this type fan, realize how heavy it is. It's a handful.....

atomidude · Post by **atomidude** » Tue Apr 05, 2005 2:43 pm

it's weight is 420g, but i don't see why this would be a problem

Bluefront · Post by **Bluefront** » Tue Apr 05, 2005 2:55 pm

Tell you what...if you'd try to use this as a case fan mounted vertically, I'll bet it would eventually stretch/break those typical rubber fan mounts.

If you'd put it on a CPU heatsink, the weight of the fan alone would push Intel's weight limit.

We'll see....

atomidude · Post by **atomidude** » Tue Apr 05, 2005 3:03 pm

not a problem for me, this is how i'm going to mount the fan:

as long as it weights less than 2.0 Kg it should be safe

IIRC, the 92cm Vantec Tornado pulls 1.0A. So that high a current draw is not completely unheard of...

StarfishChris · Post by **StarfishChris** » Tue Apr 05, 2005 3:27 pm

Equally, the fans that sport such high current ratings are not unheard (of)

Aluminium fans seem nice, but how successfully can you decouple the big ones (other than atomidude's method? Most 'traditional' methods I can think of could have problems holding half a kilo in for long periods of time, and it almost certainly isn't well-balanced enough for hardmounting.

atomidude · Post by **atomidude** » Tue Apr 05, 2005 11:14 pm

so guys, if my mobo can supply only 600mA to the cpu fan header when the fan needs 1,000mA, does that mean the fan could do any damage?

Most likely is the fan header will short out and stop providing the fan with power. It's possible something else could be effected but I believe it unlikely unless the board is about to fail anways.

And Tornado fans fall into my ridiculous category. 92x38 pushing 5K rpms is just crazy.

But looking at it again 1.0 probably isn't crazy for a 120x38, it does seem high to me for a fan that is supposed to be quiet. Still there's good potential here.

Shadowknight · Post by **Shadowknight** » Wed Apr 06, 2005 2:04 pm

I don't know the weight of the evercool aluminum fan off hand, but the verax rubbersticks sold through Directron have NO problem keeping in place in my case.

atomidude · Post by **atomidude** » Mon Apr 11, 2005 5:01 pm

i asked the manufacturer when the fan is going to be available in Australia. it seems i'll have to wait about a month...

it seems impossible to find any other reviews of this promissing aluminium fan. anybody got their hands on it yet?
