Great Case Fan - $0.99

[stevejst]

They're both good quality. The Panaflow is slightly quieter, but sleeve bearing will give it maybe 50-75% of the NMB's lifespan in cool environments, far shorter lifespan in hot environments. NMB would be better choice for a heatsink or PSU because of it's dual ball bearings.

Sleeve bearing fans are of no good quality, a sleeve bearing fan will last a third or even a quarter of the lifetime of a double ball bearing fan.
The panaflo fans he is talking about are not sleeve bearing, they are hidro-wave bearing fans, and very unique.
I cannot find the MTBF at Panasonic site but my best bet is that they are more durable than ball bearing fans.

Of course you'll pay more.

yah i agree w/ steve... best to juss go w/ panaflos for their ball bearings... they are great

 

[mindless1]

A properly balanced high-precision sleeve-bearing fan can last several years, but typically the sleeve-bearing is used in cheaper, poorly balanced fans, and so there are reasons even beyond the bearing type that determine lifespan. This is not to suggest that the L1A is low quality, it's good (for a sleeve-bearing fan).

Hydrowave IS a sleeve bearing. It does not decrease the wear problems associated with other quality sleeve bearing fans except on the thrust washer... The thrust washer is NOT the typical failure point. The L1A is good quality for a sleeve-bearing fan but make no mistake, it's a standard sleeve-bearing except the face of the bearing is rippled to allow a tiny bit of oil to be trapped under the thrust washer. They definitely do not last as long as a good quality ball-bearing fans, are not more durable than Panaflow's ball-bearing models, which are more comparible to the NMB ball-bearing models for lifespan.

 

[stevejst]

Hidro-wave bearing IS NOT SLEEVE bearing though the fans both contain fluid, if that is what you are talking about.
You know you are wrong as with that nonsense with Delta salvage and you cannot admit that.
I am going to let you enjoy it.

 

[stevejst]

And whoever else thinks that this Directron salvage operation will get you some superb quality that you could not find anywhere else, I wish you good luck. The way it goes they might start selling turbine parts to you.
That this $1 fan turning into $5 fan and then into more, and even more time wasted is a better deal than a Panaflo fan or NBM fan, if that is so special, at SVC, just doesn't cut it.

 

[mindless1]

stevejst, you are starting to seem a little like a troll, except that many trolls actually know what they're talking about.

This document shows the sleeve bearing. Note that it plainly says (at the bottom): "The radial direction analysis shown above is essentially the same as a traditional
sleeve bearing. Panasonic?s unique HWB reduces the axial contact."
Radial contact is where the greatest wear and risk of seizure occurs.

One other thing should be made clear... "L1A" is not a designation that means Hydrowave bearing, although the L1A's appearing in AT threads and most commonly available on the 'net ARE the hydrowave bearing. The determination of bearing type is the third character in the part number, with Hydrowave being "A" and ball-bearing being "K". Example: the L1A's in the Anandtech threads have usually been "FBA08A12L1A"... the "L1A" actually means the lowest-RPM , two-lead model.

As for my Delta PSUs, they are still doing great, I'm touched that you're so concerned.

Right

I have read the document before you did, if that helps you. What do you know about "radial analysis?"
Do you have a degree in physics?
I see you are doing quite a reasearch to support your thesis, who knows if I "troll" it further, you might learn more.

 

[Packy]

You people crack me up

 

[frastini]

I just got a pack of 10 of these NMB fans, from the first one I've tested.. 25 CFM 22db sounds about right.

the 3 pin connector isnt the standard one most fans come with and is kinda short.. but it works.

No 7volt mods are needed if 22 db is ok with you.

I ordered the NMB fans from both Directron and SVC and played around with them this past weekend. Here is a comparison:

Directron:
NMB Model# 3110KL-04W-B19
0.13A
Made in China
Three wire propriatary connector. Same as Dell used. Have to slice a little notch off at the end to fit on standard three wire MB connector.
Runs at ~2200 RPM according to my MB sensor.

SVC:
NMB Model# 3110KL-04W-B19
0.06A
Made in Thailand
Three wire propriatary connector. Different from above connector. Has a little "pen" type clip that you need to cut off.
Cannot determine RPM because MB cannot sense RPM. Fan appears to be slower than the other fan based on the feel of the air pressure on my hand.

So, they both appear to be OEM, possibly for different PC manufacturers, both have the same model number but the amps(?) and speed are different and the RPM sensor does not work on the SVC version.


I like the Directron fan because the RPM sensor works. I used it to replace the fan on my GC68 HSF.
Since we are now on the subject of the GC68 from SVC. This HSF does appear to be made by Akasa cause when I removed the original fan the hold down clip (can't remember the official name for it right now) had Akasa stamped on it. Also, the GC68 is actually model GC118 as can be seen here on the Galaxy Tech website.. The original fan is made by "CREAIR", model DFC802512M

This is more or less known, and debated here in the thread about Agoia XP 1600.
Except that the cooler SVC's "GC68" is not GC118 but GC118 with a slower fan, and that this cooler is not made by Akasa but for Akasa. Galaxy is also OEM for AoC, YS-Tech, and Nexgen.

 

[stevejst]

You can also find two other related threads about SVC "GC68" with the same people, including me, arguing about this cooler over and over.
Some of them are still looking for glasses to check if there is "Akasa" written on them.
The others are still looking for "proof" of magic performance of this 0.683 thermal resistance cooler. I am assuming you will try the same?

If you are really looking for a performance cooler, SVC has one for $16 only, TI-V77L. I don't really know what fan they put on it. Newegg has 5800RPM fan on it which is a sort of loud, and that for $20. That cooler will scorch your GC.
If you want to have it quiet, then newegg has Arkua 7528 which is fairly quiet for performance cooler, and cheap for $22 shipped. These coolers are as cheap as you can get for a good performance cooler. You don't have to believe me, the reviews can be found easily on the web.

If you really like the shape of GC then there is another one CUD-725 by Evercool, already outdated but all-copper cooler which you can get for $18 from nexfan with system blower included. It cannot measure up to Arkua but it is a decent cooler and with thermal resistance of 0.5 better than GC while equally quiet.

Once you try any overclocking cooler then you will know that you don't have to tolerate the CPU temperatures over 50C or worse.

 

[Lanyap]

I don't plan to overclock using the GC68/GC118, I just like the way it looks. I slapped it on a Duron 900 I installed on a ECS K7S5A this past weekend while I was playing around and I decided to check out my new NMB fans.

You must work for Galaxy or be a HSF expert with all of the knowledge that you have on this subject?

 

[stevejst]

You must work for Galaxy

Nope, but it helps to know some Chinese.
