Sony Fluid Dynamic Bearings (FDB) on Scythe and Thermalright fans

Both Scythe and Thermalright advertise Fluid dynamic bearings on some of their fans. With Scythe, the fans are S-Flex. With TR, they are TR-FDB series.

Links: http://www.scythe-usa.com/product/ac...ex_detail.html
http://www.thermalright.com/new_a_pa...r_fdb_fan.html

To me, these fans look to be at least siblings, if not quite identical:

This last pic shows that the injection ports on the frame molds are not in the same place. Otherwise, because these fans are so similar I have tested them together. The players:

--------------------------------------------------------

Since the fans were so similar, I did some tandem testing, taking the Thermalright and one of the S-Flexes and putting them in various combinations. Part of the reason was that I wanted to see what difference it would make to temps with different output fans – higher as intake vs higher as exhaust. Nothing terribly profound, just checkin’ things out.

S-Flex 1200 > TR-FDB-1300

Speed: 1210 > 1375 RPM
CPU temp over ambient: 56c
SPL: 28 dBA


TR-FDB-1300 > S-Flex-1200

Speed: 1350 > 1225 RPM
CPU temp over ambient: 54c
SPL: 28 dBA
“Annoying buzz”


S-Flex 1600 > TR-FDB-1300

Speed: 1500 > 1360 RPM
CPU temp over ambient: 55c
SPL: 31 dBA
“Annoying whine.”


TR-FDB-1300 > S-Flex-1600

Speed: 1360 > 1510 RPM
CPU temp over ambient: 55c
SPL: 32.5 dBA
“Annoying buzz”

Not a terribly promising approach. I’m not event tempted to try matched S-Flexes or matched TR-FDB’s.

Thermalright

X-Silent 140

One of my very favorite fans. Quiet. Easy on the ears. Nice amount of air. The only drawback: pointing the output upward makes it vibrate, as if it is struggling. But mounted any other way it is wonderful.

Thermaltake

A2018

Well! After getting this relatively inexpensive fan, I just had to get another. This despite the fact that the first one of these drew blood – a lot of blood – when it bit my finger.

The A2018 comes with a high-quality slot-mounted speed control as well as a thermal sensor for thermal speed control. It has the highest range of all my fans for RPM from 5 volts to 12 volts.

Link: http://www.thermaltakeusa.com/Produc...4&ID=1725#Tab0

Thermaltake A2018 Specs

Size: 120x25mm, 7 blades
Bearing: One Ball, one Sleeve
Speed: 1300 to 2800 RPM
Airflow: 38.6 to 93.7 CFM
SPL: 17 to 46.5 dBA
Static Pressure: 1.5 – 4.1 mmH2O
Features: Thermal and manual speed controls. Very pretty LED’s

Results on the Megahalems 12v:

Speed: 2800 RPM (average)
CPU temp over ambient: 51.5c
SPL: 43 dBA
“One ferocious fan.”

Results on the Megahalems 12v, tandem mount (two fans):

“Two ferocious fans.”

Note that the pair beat a San Ace -H101 in temp, but boy are they noisy.
Looking carefully at the frame and the specs, the fan part looks like it might be a Yate Loon D12BH-12, but with just a bit more juice.

“Faint clicking.” I’m shocked I could hear that. I had to get really close.

Results on the Megahalems 5v, tandem mount (two fans):

Speed: 445 RPM (average)
CPU temp over ambient: fail
SPL: 15 dBA

Clearly, the manual fan control does not get down to 5v.

Yate Loon

Is it a genuine Yate Loon or a fake Yate loon? Controversies all over the place. A lot of controversy for some of the most consistently inexpensive fans out there. On the other hand, at full voltage YL’s are some of the most consistently good fans out there. Undervolted, they tend to click. YMMV.

BTW – Most YL fans have closed corners.

Let’s start with 140mm fans:

Link: http://www.yateloon.com/style/conten...=8511&id=38839

Yate Loon D14SM-12

Yate Loon D14SM-12 Specs

Size: 140x25mm, 7 blades
Bearing: Sleeve
Speed: 1400 RPM
Airflow: 62 CFM
SPL: 29 dBA
Static Pressure: na

Results on the Megahalems 12v:

Speed: 1250 RPM
CPU temp over ambient: 57c
SPL: 27 dBA
“Soft”

------------------------------------------------------------

Yate Loon D14SH-12

Yate Loon D14SH-12 Specs

Size: 140x25mm, 7 blades
Bearing: Sleeve
Speed: 2800 RPM
Airflow: 140 CFM
SPL: 48.5 dBA
Static Pressure: na

Results on the Megahalems 12v:

Speed: 1900 RPM
CPU temp over ambient: 55.5c
SPL: 34 dBA
“Soft high hum.”

I think I’d like to see that 2800 RPM 140mm fan. It would be quite something. But I’m guessing it’s a typo, and the spec is really 1800 RPM. As it is, this 1900 RPM fan does not cool as well as either the Kaze Maru 1900 or the Kaze Maru 1700, and it’s a bit noisier than the KM2-1700. The blade count seems to make a difference here.

-------------------------------------------------------------

Note those dimples flanking the screw holes. Looks an awful lot like a Nexus D12SL-12 Real Silent fan, eh?

Link: http://www.yateloon.com/style/conten...=8511&id=38837

Yate Loon D12SL-12 Specs

Size: 120x25mm, 7 blades

SPL: 28 dBA
Static Pressure: na

Results on the Megahalems 12v:

Speed: 1310 RPM
CPU temp over ambient: 58c
SPL: 23 dBA
“Quiet fast clicking.”

Hmm. It appears that YL can put quiet electronics into a client’s fan, but they don’t do it for their own brand.
----------------------------------------------

Yate Loon D12SL-12, blue LED’s

Very pretty, but the blade shape resembles the D14Sx-12’s, not the other D12SL-12 or the other D12S’s.

Link: http://www.yateloon.com/style/conten...=8511&id=38837

Size: 120x25mm, 7 blades
Bearing: Sleeve
Speed: 1350 RPM

SPL: 28 dBA
Static Pressure: na

Results on the Megahalems 12v:

Speed: 1220 RPM
CPU temp over ambient: 56.5c
SPL: 20 dBA
“Quiet fast clicking; mostly a quiet hum.”

Better results than the black fan, despite that fan’s higher RPM. Blade shape?

Results on the Megahalems 12v, tandem mount (two fans)
(black intake, LED exhaust):

Speed: 1270 RPM, average
CPU temp over ambient: 56.5c
SPL: 24.5 dBA

----------------------------------------------------------

Yate Loon D12SH-12

This is the fan that some reviewers dote on. I got three of them, one from Petra’s Tech Shop, one from Jab-Tech and one from Modders Mart.

Results on the Megahalems 12v:

“Fan humming.”

Results on the Megahalems 12v, tandem mount (two fans):

Speed: 2000 RPM (average)
CPU temp over ambient: 50.5c
SPL: 37.5 dBA
“Two fans humming; pleasant; doesn't sound as loud as it measures.”

Here is a pair of fans that matches a single San Ace -H101 for temp, and beats it for noise. These fans can be had for $3.70 each. If you buy three or more, you can get them for $3.30 each. – Link: http://www.jab-tech.com/YATE-LOON-12...d-pr-3771.html - I can’t tell the difference in quality, so I won’t pay more. I figure I can buy a bunch, and then if they wear out replace them.

Good stuff,

No NoiseBlockers: Easily one of the top 5 contenders in the CFM/PRESSURE/NOISE trade-off.

Holy crap. +1, definitely. This really needs to be linked to in Shadowclock's guide. I think, and this may be a tall order, it's worth repeating the thermal tests on the new Armageddon, and the TRUE Rev.A, if you can get them, to show just how well the fans that are known for producing good static pressure really perform. Also, as noted, it's more than worth including Noiseblockers in the tests, too.
