and i dont mean that in a pun sense either.

There horrible on a radiator. :X

I would recomend you getting some better fans for that rad.

Yate Loom makes great fans, Zalman F series fans are also great.

My personal favorate are slightly thicker then normal fans called scythe Ultra Kaze's, There 38mm.

My ultimate favorate, but very expensive, and very hard find is the sanyo denki sanace.

I am getting Zalman ZM-F3 and Yate Loon D12SH-12 for the same price i.e. $10.00 each incl p&p. Which one would be better?

Afternoon Fellas !

According to our supplier Yate loon has open and closed corner molds. You are correct that we don't buy from Yate Loon and the distributor who sells these to just about everyone in USA (except Petra it seems) uses a trading company in China to purchase from Yate loon. (Hence the reason why Yate Loon say our distributor isn't a customer)

We sold our frist Yate Loon fan June 30th 2005 and have sold over 25,000 since then with no complaints and barely any RMA's (probably less than 50).

I'll update this if/when I get any more info.

Shrug, they seem to work fine and they were a good price. Jab-Tech has treated me well so far, I'm sure if there is a problem, John will take care of it.

Vapor

Yate Loons are a big deal. In modern computers, we've shifted toward numerous large, quiet fans...so price becomes more noticeable in end-cost. And they're the least expensive fans you can buy, come in many varieties, and ultimately, pretty damned good. Actually...some are great and others suck.

In my testing: one thing became very clear, the one variable for determining quality is place of purchase. Petra's Tech Shop Yate Loons outperformed the others by quite a bit. And most importantly...they performed differently. They had different physical characteristics.

Simply, Petras has different Yates than everyone else.

Further investigation and chatting brought up this important fact: Petras is the only retailer to deal directly with Yate Loon. Other retailers (Jab-Tech, P-PCs, etc) unfortunately use a middle-man. This middle-man can apparently sell them fans at costs below what Yate Loon would sell to them, so the business choice was clear.

Why did Petras stick with Yate Loon directly? Not sure...but we should be glad they did. Their $4 Yate Loons are among the best-as-tested fans, competing and beating fans 2-6 times their price. Furthermore, they really don't have any 'bad' qualities other than being sleeve bearing (which isn't a bad thing for most people, but it makes a difference for some).

How are PTS fans different from non-PTS fans:

1) different voltage scaling. 12V may be similar...but at 5V the non-PTS fans spin noticeably slower (but aren't that much quieter, if at all). This could be a good thing, but it does sacrifice tunability in the mid-range.

2) different radiator performance. The fans may have identical blade structures, but put them both on a radiator and suddenly the non-PTS is sucking wind. PTS Yates have CFM-loss numbers comparable to most 38mm-thick fans. They're excellent on radiators.

3) different performance growth over time. 0-hour numbers are very similar. That is, take the out of the box, plug them in and test, and they appear to be the same. Run them both for 24-hours and retest and like most fans, the PTS Yates get 1-2% better. The non-PTS fans drop back nearly 10% and often develop odd noises. Ultimately, performance for the long-term is important, not performance right when you get them. PTS fans have a major advantage here.

4) external appearance. There are minute differences in external appearance, the 5xx are very noticeable, 6xx less so, and 7xx nearly or exactly identical. This means that new fans are no longer externally discernible. This is not a good thing...at least with the older fans you could pick them up, look at them, and know which one was the good one.

5) internal appearance. PTS has done a take-down of some of the various offerings and the internal differences were shocking. Nothing 'bad' necessarily, but it was clear they are very different fans.

Petra's Yate loons are better?

No idea, that thread is rather old. I sent a message to John at Jab-Tech and asked him to chime in.

I am worried too as Petra don't ship to UK and I want to buy Yate Loon D12SH-12.

 

[Gillbot]

Honestly, it doesn't matter much to me. They are fans, they work and they are cheap. You'll be hard pressed to find any decent 120mm fan for under $4 each anywhere.

John from Jab-Tech replied:

James I don't have an account on Anandtech, If I get chance tomorrow I will make one.. In referance to the Yates and the old XS testing done by Vapor, well the fans from me and the fans from Petra were different.. But if you look at the yates you will see a 3 digit number, something like 801. At the time we didn't know what this number was, it is the date of manufacture, 801 = 2008 January. The fans vapor tested were manufactured about 18 months apart, I had 50x and Petra had 60x and that is why their was differances then.. We have 804, 805 and 806 model now so they are pretty much as new as they get. If their was a comparison of Apples to apples (Same Manufacture month and Frame design (open or closed corner)) You will find they are exactly the same.

Yayy!! Cheers Gilbot

 

[Gillbot]

I believe the ones I got in this batch were 807 so they are rather recent, I'd guess 2008 July.

Are these the fans you are talking about? They are being offered on ebay for dirt cheap ($8 each). Please advice me and I will buy them immediately.

OMG, didn't know that. Sorry Gillbot, I apologise.

 

[aigomorla]

sorry it took me so long to post this.

I was in the middle of picking up a lot.

These are the sanaces im talking about:

http://i125.photobucket.com/al...aigomorla/IMG_0113.jpg

There not cheap fans. You'd be lucky to find them for 10 dollars each.

Thanks Aigo I got these Sanyo fans and they rock. Also verified and they are Japanese make. I can now understand why you enphasised on static pressure for fans. I could well see the difference when I tried both Sanyo Denski and Noctua fans and the latter sucked.

Btw, I am still wondering how come I got them for $8 each while Petra are selling them for abt $25.

Cheers

IIRC, the ebay link you posted was for 24v fans, so that may be why. There are places out there that sells them for under petra's price but they are semi-hard to find. Usually whan any PC reseller gets them in stock, they sell out fast. It's all supply/demand really.

Does it affect the performance?

 

[Gillbot]

Of course. If a fan is rated to flow x amount at 24v, it will be greatly reduced if only fed 12v.

 

[aigomorla]

but most of the time you run the fan undervolted.

So a 24V fan at full blast should be comparable to a 7-8V 12V fan which is where you want to be at anyhow.

 

[Tate7]

Thanks Gillbot and Aigo

Can't 24 volts be directly fed from the PSU to the fan? Will it then even further improve the performance is it runs at 24 V with full blast?

 

[WoodButcher]

24 can't be had from standard atx psu w/o modification and then it's not likely to run the computer. As aigo pointed out,most of the time in a WC system you run the fans under volted, 2 reasons one being noise of course but the second is not readily apparent. This is why experienced builders always recommend overkill in the rad department. If you have more radiator than you need you can use slower / quieter fans, you'll reach a point of diminishing return, for the most part the fans in my PC are run at 5v which will keep my system about 30-32C at idle w/ a 72F room temp. At 12v it will be about 2C lower but I can get that 2 degree drop at less than 9v as well so why have the added noise?
Sorry I didn't see the link, I don't know how 24v fans will run, I never tried it so keep us posted.

I rarely undervolt mine. Either deafening roar or the PC is off, LOL!
