Petra's & Jabtech's Yate Loon - SLs mini-review

[jinsean]

This "mini-reivew" (if you can even call it that) is to help those out there who are unsure/concerned about yate loon SL fans. These results are subjective and not scientific. I do have pretty sensitive hearing and am always concerned about the noise generated by my PC.

Ok, so I finally decided to test the 12 Yate Loon - SLs i got from jabtech. I had ordered 4 Yate Loon - SLs from Petra as well.

Differences:

*JT(Jabtech) YL-SL has model # 511 (or five hundred something). Petra YL-SL has model #705 (or seven hundred something). Sorry for the vague #'s I don't have the fans in front of me atm.

*Petra's has a closed corner fans and has a much sturdier feel to the plastic (less vibration possibly), while JT's has open corner and much flimsier feel to the plastic enclosing the fan.

*Petra's fan definitely generates more CFM. How do I know? I felt the air of Petra's versus JT's fan on my face. I could definitely tell Petra's was blowing more air @ 12v. I'm guessing the JT fan has a lower RPM rating, while Petra's actually holds to the specs of +1350RPM

*JT's fan makes an annoying buzzing/clicking noise @ 5v and 12v. Petra's has a clean smoothe sound to the fan.

*The buzzing/clicking noise from JT fans can vary if you have the fan blowing air horizontally. This effect is minimized if you have the fan blowing air vertically. For me this is important because I'll want to use these fans on the top mount rad of my case and not rear mount

*Both Petra & JT fans are pretty inaudible when more than a 1-2 foot away, but of course in the dead(silence) of night, the JT fan can be a little annoying to hear compared to petra's.

* The quality of the sound and construction was CONSISTENT for all the fans tested. So it's not a matter of quality control, but two different types of fan "manufacturered" by "yate loon."

My suggestion? Pay a $1 or $.50 more for Petra's YateLoons SL. I don't know about the SM or SH, but I wish that I could return all my JT yate loon SL fans and pay more for petras.

EDIT: The batch #'s are 705 and 511. The clicking noise is pissing me off. I'm going to order more YL-SLs from petras. Anyone want to buy some YL-SL 511s for $2 a piece + shipping? I have 12.
EDIT: The 705s have more of a curved blade design versus the 511s have more of a straight blade design (probably effects how much air the fans can move)

[lee143]

hm thanks for the review. It has helped me on my selection of fans to use on my oncoming WC setup.

[Cathar]

Can you please confirm for me that the Petra fan, the one with the 7xx batch number, has more curved fan blades than the other fan (5xx batch number).

I have both types here, straight/curved, and the curved fan blade version is markedly better on my testbed.

Odd though, because the Tricod Science fans I have here are a very near (not exact) copy of the straight-blade Yate Loon, yet its air-flow behavior is more like the curved bladed Yate.

[evoic]

Interesting.

Verrrrry interesting.

I'll have to check mine when I get home.
They are very queit compared to any other fan I've ever dealth with, but they do not tend to push a ton of air.

I have them doubled up (2 strapped to each other) in the middle of my case in order to push as much air as possible into my Scythe Mine Rev. B and it's internal fan assembly.

[rogueagent6]

My model 703 yates that I got from Petra's recently have 7 blades.

[Bail_w]

The one i got from jab-tech are model 610 with closed corners.

[AndyM]

And to add more confusion to the mix...my JabTech YL's I got last month were 704 closed corner fans. Who's got what?

I believe Alex @ Petra stated that all the YL-SLs from Petras were closed corner. So you're pretty much guaranteed (imo) a higher quality fan compared to what appears a mystery (white) box of Jabtech's YL-SLs.

does that fan make a clicking noise?

[kevinbo03]

I've got 8 SL's from Petra's right next to me. They are all closed corner 705's; No clicking at all.

I heard of the white box, but the JabTech fans I got were no box fans. I guess flip a coin.

[Turtle 1]

A little off topic but I really don't get excited about fans . But the UPS man arrived today . With the 6 new fans I wanted to test with our system . I will tell you straight out these fans got all of us impressed.

They move air they are quit they move air they are quit I said that once already didn't I .

The fan is a Noctua nf-S12 120mm .

They move air they are quit . Result were outstanding

[Pen3]

quit or quiet?

I can confirm that the YL-SL 705s I have have more curved fan blade than the 511s, which are much straighter blade design. Probably has a lot to do w/ how much air the fans can move even at the the same RPM. Good catch, Cathar.

[Turtle 1]

These are plain and quiet . But check out that fan pitch

Stick them on a radiator and be prepared to be underwhelmed, if everything I've read about these fans is true (and no, not just from looking at Vapor's tests).

[Turtle 1]

We did today and were really happy about the results. They did the job and they were quiet

I don't know what you have heard about these fans cathar but these are perfect for us 48cfm @17dB(a) is good enough for a us. using 4 160's . The hardware we used tho we may not be getting a fair perspective . Idle temps 28c load 40c on the Qcore cpu used running cpu fsb of 400 for 1600 with a 10 multi. 2 1950xt in crossfire no O/C. gpu Idle 39c load 55c . core cpu v @ 1.39. real .

[ziddey]

I ordered from JT at the end of dec and got closed 610's

[MaxxxRacer]

I've gotten about 50 yates from Jab-Tech and they were all closed corner and curved blades.

Turtle 1,

Excuse me for asking. You have an Intel Kentsfield cpu. It is running at a 1600 FSB, which means 400 Mhz frequency, and a multiplier of 10. That provides an operating frequency of 4.0 GHz. That itself blows my mind because I struggle to reach 3.8 Ghz stably, and its more likely 3.75 Ghz that I am stable at.

No, you say that you are using a couple of PA160.1s to cool the cpu. You have an idle temp of 28C and a load of 40C. That's even more incredulous. I have an idle temp in the mid 30s, off an ambient of about 22C. My load temps on a hot summer day are not less than the low to mid 50s. As for hardware, I am using double PA120.3s. You are using quiet 48 cfm Noctuas. I am using 68 cfm Papsts and on both sides of the radiator, and not downvolted.

Someone in my office IT department took it upon himself to pay an outrageous (and I mean truly outrageous) price to buy a new 3.0 Ghz QX6850 to try to reach 4 Ghz, and hasn't managed.

There must be something you know that I don't know.

My questions as well..I have a PA160 with a E6600 at 1.38v real..I am using a Panaflo 120x38 fan that produces more static pressure than my YL...at 12v this will move 70cfm(my gpu is not overclocked unless running 3D..its a x1900xt)

my idle temps are 32/33 on core 0/1...load in the mid 50s with prime95 blend for 12hrs with loop below and as described

How are you getting a quad core to run so cool?????

[Cathar]

Mayhaps reporting case temp, and not core temp?

[IanY]

Even for case temps, how does he managed that? lol My case temps are higher that that and with more noisy fans as well.

I'm no math whiz, but wouldn't 4 160's be very similiar to your 2 120.3's?? Could it be that, that you misread 2 instead of 4?
