Undervoltron,
My 8025M 12's do start at 5V. They are wired to 4 pin molex using the 5V mod (Red and black wire only). They are completely silent at 5V. I dont think you can go wrong with these- absolutely no clicking.

velvet45,

Thanks for the tip. I actually have one of the 120s as my exhaust, but at 7V. I hard-wire all my fans to get the desired voltage, but I cannot get it to start wiring it for 5V (yes I double-checked my wiring). Luckily, it is still very quiet at 7V. I might pick up a fanmate and see if it starts at a lower voltage that way.

Yate Loons at CompUSA

Post by dfrost » Thu Mar 24, 2005 4:34 pm

Black 120 mm sleeve bearing Yank Loons with speed sensors are available for the impatient at CompUSA for $10. I'm surprised frankgehry didn't already mention it after identifying this source in his thread, and Joshd2012 is using them in his Project Black Hole.

They're labelled "Mad Dog"on the fan sticker, but look just like all the pictures I can find of YL's. Frank and Bluetooth say that they're D12SM-12's. I can only say that these old ears can't tell the difference if they're off or on at 5V, and they move more air at that voltage (despite packaging that says 6V starting voltage) then the Antec Sonata stock exhaust and Vantec Stealth (Sonata restricted-) intake fans they replaced. Speed-sensing header on the Abit MB said 1200 rpm at 8V (Vantec was 960 rpm at 8V).

D,

I did buy one and somewhere mentioned that my copy was not as good as the pctekonline or tekgems d12sm-12, but I definitely think its a yate loon. Maybe yours is a good one. - FG

The description says "120Mm Ultra Quiet Ball Bearing Case Fan"

The specs say:
Fan Type: Sleeve Bearing
Noise Level: 40.5 dBA

So even if the picture is a Yate Loon (I don't really know), I would be suspicious of the item.

Those are louder and faster than the Mad Dogs. And more expensive.

I just bought 10 each of the these YL 8cm and 12cm fans from PCTEK and all I can say is that I love them. Seems like a perfect balance of air movement and noise at 12 volts. No whining or clicking. Just a smoooth whooshing noise. I have 3 of the 12cm ones in the front of my case cooling my hard drives, one in the back and one in my Super Tornado PSU. I replaced my L1A on CPU heatsink with one of the 8cm ones. Except for the PSU, all of these are running at 12v at the moment. At this voltage they are certainly not "silent" but they seem to be moving quite a bit of air for the noise level. It wouldn't surprise me if these fans are in fact the quietest ones currently available. I'm sure I'll eventually undervolt most of these down to 6 or 7 volts and report on the results. For now I'm enjoying my cool case. The one in my PSU is so quiet that I can't tell it is on unless I actually look at the spinning blades.

Gojira, can you adjust the RPM on these? (120mm)

I have a few of the PCTek D12SM-12s. You can certainly adjust the RPMs with voltage (or PWM), but there is no RPM sensing. These fans have just two wires.

No more or less than you can with any fan. It doesn't include any rheostats or special connectors for any voltage adjustment. Not that I would expect that for the price. I am now looking into making voltage divider circuits to run them at 6 volts or some other energy efficient way of lowering the voltage to them. I don't know if I trust that 7 volt mod. Although it might be a good excuse to replace my PSU with a newer, more efficient model.

are pcteks 80mm Sleeve Bearing? i though that the 8025M is ball bearing and the 80SM is sleeve bearing, which would indicate that they are not sleeve bearning? how much bearing noise is it from them? i plan to buy eighter these or panaflos from dorothy bradbury.

80 panaflo or yate loons

Post by frankgehry » Sat Apr 16, 2005 2:04 pm

Cheesewhiz,

Pcteks are sleeve bearing. I wish you had given complete model numbers but I guess you mean D80SM -12. My D80SM-12 is much quieter that that my panaflos. I don't actually have an 8025m, but I know there have been other posts about it so you can search for pctec or 8025m. I have a feeling that the pctek 80's are going to be inconsistent - some are going to have bearing noise and others will be fine. Dorothy on the other hand, is supposed to pick out the good ones. I don't know how much you can get panaflos for but I'm sure the quality would be better and more consistent than the pctek yate loons. You don't indicate where you live so shipping yate loons might make them more expensive. Search for the other posts but I'm sure that the 8025's are the same as the D80SM-12's. If you look at the yate loon web site you will not see 8025m's. - FG

As would all of us. If you get him on the phone again, see if he can get a good price on some D12SL-12s.
I live nearby and went to PCTek to pick up two of the 80mm fans (about two weeks ago). Nice guys, though there's a reason some stores should only be online.

The fan label:
DC FAN
8025M12
Yate Loon
DC 12V 0.14A
It is 3-pin, though the picture on the box shows 4-pin.

These YL fans are noticeably noisier ("whr-thpt, whr-thpt") than an 80mm Nexus or an 80mm Panaflow I have. Though none of them (YL, Nexus, Pana) had been used much when I compared them -- does a break-in period really make a difference?

Yes - you can get 80, 92, and 120 chieftec/yateloons from www.ichbinleise.de

I've only seen D12SM-12's on their web site but you could ask for the slower ones. - FG

Shipping was 19 euros which is about $25 for 5 fans.

Hi, I'm new to this board, and was looking for the D12SM-12 fans, so I ordered me a couple off the pctekonline website and this is what they sent me. Are these Yate Loons, clones, or did they just send me the wrong ones? They do have the closed corners and the blades look similar though.

Model # DFS122512M

No, this is not a Yate Loon. I've never seen Yate Loon's with that pattern around the corner hole.

But have you tried them? How do they sound?

Appears to be a seperate company. Here is the website where you can find the specs:

No, i havent tried them yet to see how they sound, might hook 'em up later tonight though. Might have to give pctek a call to see if they will return them, if they don't sound good.

Actually, both Yate Loon and Young Lin are companies in Taiwan that "have factories" in China. I have a very strong suspicion that these factories are not owned by the Taiwan companies and just do contract manufacturing for more than one foreign company, which is why the fans tend to look very similar.

However, the fan in question does not match up in terms of specs with any of the Yate Loons.

It also doesn't have the closed corners of 120mm Yate Loons.

That can't be right, a 2500rpm 12cm fan would have to move more than 44cfm, and I'm quite sure it could not have 7 blades and such a small hub.

I got to looking at this fan a little closer and the 12V current rating says 0.23A on the label but 0.19A on the company's website, so I'm thinking it probably has the wrong label on it or something. as for the RPM, 2500 does seem a little high for 40 CFM, should probably be closer to 1500 or so. After looking at pictures of the Yate Loon, the fan blades look almost exactly the same, but the frame's different, although it does have the closed corners. Looks like they grabbed a bunch of different parts out of the parts bin, and threw it together. I emailed PCTeK to see what the deal was, prolly be tomorrow before i get a response.

I just received 2 of the 120 Young Lins and 2 80 yate loons. The Young Lins do have closed corners.

They both list the Amps at 0.23 as opposed to 0.19 shown on the website. I'm guessing that the specs for the DFS122512H fit this fan better then those for the DFS122512M. It seems like a pretty fast fan.

I've listened to one of the Young Lins out of the case attached to a fan controller. I didn't hear any clicking or odd motor noises except maybe a bit of whine at higher speeds. Most of the noise was from air movement. In the case I can't hear it at low speeds. I'll check it out more this weekend. - but so far they seem like pretty good fans.

I'm a little perturbed at not getting what I ordered, but the fans seem okay so far and will probably meet my needs so I'll not be returning them, but if they are selling these as "generic" fans they should say so on their web site.

After emailing PCTek about this, they finally sent me a response. Here is what they wrote:

"The DFS122512M and the D12SM-12 are OEM by the same factory in China. The product is the same. The only difference is the Label.

Usually we only carry the Yate Loon version. But for the last shipment from China, the factory sent us the Young Lin version by mistake.

If you have to get the Yate Loon version, please let us know. We still have a few left from the earlier shipment.

We apologize for the problem."

I, personally don't think this is the same fan, it runs smooth enough, but with higher rpm's and a good bit of air noise. The stated 2500 rpms sounds about right.

Figured it out guys:

http://store.yahoo.com/pctekonline/12x12cmcasefan.html

is the link posted in the original post which was made quite a while ago.

http://store.yahoo.com/pctekonline/12x12cmcasefan1.html

is the link to the yate loons. It looks like they changed the page due to higher demand. I bought 2 young lins, they are not as quiet as I hoped they would be, but at 7V they suit me just fine. I also picked up 2 8025M 12s. They are very quiet at 7v, and okay at 12v.
