Sanyo Denki's "New" Fan

[Zaskar]

Anyone have any opinions on Sanyo Denki's New fan the 9GV1212P1J011 compared to the older 109R1212H1011 that isn't really made anymore. (posting this here cause I really doubt anyone would care enough about this for just a case fan)
The only fan in that line listed on their site is the 109R1212H102, same as the 109R1212H1011 except it is ribbed and doesnt have the rpm readout wire.

The stats for the 109R1212H102 were:

Rated Voltage: 12
Rated Current: 0.52
Rated Input: 6.24 watts
Rated Rotating Speed: 2600
Air Flow: 2.9
Static Pressure: 64.7
Noise: 39
Mass: 260

The stats for the 9GV1212P1J011 are listed in a way that makes it hard to compare, but shows that it can operate at different power ranges well.
it has 2 sets of stats, 1 at 2.28 watts and 1 at 36 watts.

Stats for the 9GV1212P1J011 (2.28 watts):

Rated Voltage: 12
Rated Current: 0.19
Rated Input: 2.28
Rated Rotating Speed: 1,500
Air Flow: 1.49
Static Pressure: 19.8
Noise: 33
Mass: 360


Stats for the 9GV1212P1J011 (36 watts):

Rated Voltage: 12
Rated Current: 3.00
Rated Input: 36.00
Rated Rotating Speed: 6,400
Air Flow: 6.35
Static Pressure: 360.0
Noise: 64
Mass: 360


Pretty much this is to discuss which would most likely be better going by their stats. If anyone was able to take the 2 stat ranges of the newer fan to try to calculate the stats it would be at 6.24 watts so we can get a good comparison that would really be awesome.

How would you get 38 watts to the fan? All I have is a sunbeam Rhoebus that can only do 20W.

You don't, not with normal computer power supplies, but you wouldn't want to run it that high anyways. Its just showing how high it "can" go if you can supply it with that much.

Those 2 speed/watt ranges are the only ones they show, I'm assuming their a min/max range.

I think you want the 109R1212H1021 which is listed haveing no ribs (and as far as i can tell identical to the 1011).
... However it only says this on the japanese site... the english version lacks some info for some reason...

[Kilyin]

Sanyo Denkis are the Rolls Royce of fans.

Three guesses as to who said that first.

[nattoNrice]

weapon?

An ending of 21 means Ribless and without an RPM readout wire.
2 = Ribbed, no RPM wire
11 = Ribless and with RPM wire
1 = Ribbed and with RPM wire


Thats the older fan though that is impossible to find in any of those versions.

Wanted to compare this new model to the older to see if it is actually a successor to the older one.

close... little "greener"..

That's strange. I am not professing to be an expert on fans however on the japanese sanyo denki page it says that the 109R1212H1021 is the model with out 'ribs' whereas the 109R1212H102 has them.
By japanese i mean the one not in english~

yeah, nikhsub's post on OCForums way back in the day is why/when I ordered a box full of brand new Denkis at 5 dollars a pop on Ebay. Haven't had one fail me yet or make any strange noises after 4 years of abuse and no maintenance.

[Crankyhobo]

I bought a bunch of the old good version, gave two of them as a birthday present to my brother in New Zealand, he was ecstatic as he should be, a little bit of my heart felt like it was cut out and given away that day. Btw i have a couple of 40mm dual-blade turbine beasts (9CR0412S518) that i found at some server parts auction: http://img60.imageshack.us/img60/9452/dsc0066kq1.jpg (on the left of pic) I would be happy to lend to martin or someone for some testing but something tells me 40mm isn't that popular around here.

[NaeKuh]

How would you get 38 watts to the fan? All I have is a sunbeam Rhoebus that can only do 20W.

meanwell S150-12

Good for 0-13W

And should be good for 3 fans required on a radiator.

But wow, thats a ton of wattage. :X

[FuriousSalesman]

Hooking up fans directly to a Aux power supply!!! :eek: I haven't seen that done.

[Jimmer411]

by not running a fan controller ;) your sunbeam is limited to 20w per channel, where a standard molex connector goes much higher

[qdemn7]

How would you get 38 watts to the fan? All I have is a sunbeam Rhoebus that can only do 20W.By using one of these. (http://www.sidewindercomputers.com/si50warh.html)

[jcool]

My meanwell 60W sure could handle it... but I wouldn't dream of getting a fan like that. ;)

[Zaskar]

Ha.
Ok no one is using it at 36 watts :D

I want to get your opinions on how you think it would perform when running at the same power range as the older one when in comparison to it.

[Vargher Warg]

Where do you guys get your Denki's from?

My dear sister went to the States (LA) and asked if I wanted something?
sure I said! bring me a couple of those thick 38mm Sanyo Denki's please!

Three week's later she returned with ONE SilenX 38mm and said:

Look how beautiful and sexy it looks, I couldn't find any 'Sony Donkey's' !
and I didn't wanna come home empty-handed, they guy at the store
told me that this fan was better and blew the Donkey's away!

YEAH RIGHT! :rolleyes: :rofl::ROTF:

So what could I say? - I just gave her a hug and said thanks Sis!

(the worst thing is that, I think I need to install the fan in my WC build somehow
and show her, when finished! - I mean, I don't wanna break her sweet little heart!)

Maybe I can print a T-shirt that says:

My sister went to California and all I got was this lousy fan! :D

[Zaskar]

Lets not ruin this comparison with the fact that you cant get either of these anywhere :D

[Metric]

Where do you guys get your Denki's from?
Ordered mine off of ThermalFX when the price was down around $18.99/fan. Looks like they're still in-stock.

Remember those are the ribbed versions.

[Zaskar]

Does anyone know what would happen if you just plugged in the newer fan to a molex connector without going through a separate fan controller, what speed would it run at? Since it doesn't seem to have a set speed, they just list a low and a high, does that mean its going to run as high as it can with the power it has until it reaches its max?


Also anyone able to figure out how it compares to the older model at the same amount of watts?

[Crankyhobo]

Might be able to get some here

There is a few places like that, problem is their refurbished IBM server fans and they charge you more then most places would new.

[Zaskar]

Is there a way to compare the Old fan vs new fan?

We know the stats of the older one at 6.24 watts
And for the new one we know its stats for 2.28 watts and 36 watts.

Assuming the stats scale equally throughout the full range of it (A false assumption I know, but should be close enough) there should be a mathematical way to find out what the new fans main stats will be at 6.24 watts.

Just got my first email back from one of the distributors, their ~$26 each (in boxes of 20) and they really are Brand new models that Sanyo Denki just started making, no retailers were even sent any yet, you would just be using them as a middle man to order through to Sanyo Denki.

[Crankyhobo]

You should check back at that post i linked to earlier (http://www.xtremesystems.org/forums/showthread.php?t=184475) i went through today found a couple new stores most notably "Progressive Image" a US distributer with online ordering (incl stock and prices broken by volume). Another interesting thing i just found is that in japan these fans are labeled differently. Prefix F12 for 120mm... check this out:

Static pressure Vs Air Flow at various voltages (Old on left, new on right)

Heres what i think, from the information in the chars above...

Not very scientific but maybe in the ballpark

[Edited because vapor is a lot smarter than me]

[Zaskar]

Very interesting, so it seems the new one is in fact better.

It was Sager Electronics (On the Sanyo Denki America official distributor list) that said they could get order them from Sanyo Denki in boxes of 20 for $26.25, there is a 12-14 week lead time though.

[Vapor]

The fans aren't even comparable?

9GV1212P1J011's a 6400RPM 120mm fan. It draws 3A at full PWM duty. Its minimum rated running voltage is 10.2V (important since most of us undervolt to control fan speed). The 1500RPM minimum is via PWM control (not necessarily a bad thing, but who has a PWM fan controller rated for 3A?--heck, other than those motherboard headers, who has any sort of PWM fan control in their computer?).

And FWIW, static pressure is proportional to the square of the RPM of the fan (it has nothing to do with voltage).

1500*1500 / 19.8 = ~113700
6400*6400 / 360 = ~113800

So for finding out its static pressure at 2600RPM, you need 2600*2600 / 113750 = 59.43 Pa, less than the 109R1212H10xx (64.7Pa).

Airflow is linear to RPM:

1500 / 1.49 = ~1007
6400 / 6.35 = ~1008

So for finding out its airflow at 2600RPM, you need 2600/1007.5 = 2.58 m^3/min, which is also worse than the 109R1212H10xx (2.9 m^3/min).

If you trust ratings that is :p:

Regardless, this fan is not in competition with the 109R1212H10xx.

[Zaskar]

Ahh well that's too bad.

Though it was exactly the kind of informed information I was looking for, thanks Vapor :D
