[H] RIP Gentle Tyhoon fans

[BrightCandle]

I don't remember seeing an announcement about Gentle Typhoon fans being discontinued but everywhere in my country I look the fans are either out of stock or actually saying discontinued. Its seriously disappointing to see the number 1 low speed fan for radiators by quite a margin is disappearing.

So then I started looking and I found this from [H]:
http://hardforum.com/showthread.php?t=1796464

Looks like Mark @ Frozen is sending out mails to a few people in which Scythe states the partnership with Nidec is over, no outstanding supplier orders will be able to be filled.

So it looks like the partnership that made these amazing fans is finally done and we will have no more Gentle Typhoon AP11-AP15's. What a disaster.

I just bought the last 2 1150 rpm ones in any web store in the country as far as I can tell.

Guess the two I have laying around are now worth their weight in gold. LOL. When I switched over to the swiftech H220 cooler I was impressed with how nice the helix 120 fans are....and share a very similar design to the gentle typhoons with the benefit of being PWM.

I heard about this late last year.

https://www.dazmode.com/store/product/scythe_gentle_typhoon_2150rpm_69cfm_30db_fan/

lots of stock of the 2150, 1850rpm are all gone unfortunately. I ordered 6 of each a few weeks back when I picked up a new radiator for a loop rebuild.

 

[smackababy]

Lol, I made a thread about this almost a year ago. I believe you can buy a Nidec that has the exact same specs, just not labeled as a GT.

 

[BonzaiDuck]

Maybe I was hallucinating . . . I either saw a page where they were "in stock," or maybe it said "discontinued."

Main thing -- I'd heard people mention these fans for years. I looked at the specs and was stunned at the CFM, RPM (and despite that) the dBA.

How could they discontinue a fan like that? Maybe the mfgr fell on hard times . . . . something . . . . who knows?

 

[Millerboy3]

Just as i was considering getting some too. :\ This is disappointing!

Maybe I missed something about this "AeroCooler" outfit, but it looks like somebody still has "inventory:"

If these are the fans y'all want, too bad you'll order online. I'd sorta like to see the stampede.

Wow! Thanks!

 

[BonzaiDuck]

Wow! Thanks!

You're welcome. . . . But I was just doing a web search for another type of fan, and noticed all those Typhoons that didn't say "out of stock."

I always thought the name was a bit funny. No less an oxymoron, it somehow called to mind the DPNK expression "Dear Leader." But they don't make any fans. And they don't have many fans, either! In fact, I think Dennis Rodman consults with CIA coming and going . . . . heh-heh.

As someone who sold fans on a daily basis I still do not get why people get worked up over Scythe Fans. I'm not going to act like they aren't 1-5% better than other brands, but is it really worth the incredible price difference for the 1-5% gains? This isn't even counting the random factor of a fan being built; no two fans are identical.

I settled myself for Thermalright fluid bearing fans and haven't looked back. That and I got them for 8$ a pop.

Maybe you know of offerings that I haven't been able to find.

I want, if possible, a 120x38mm fan, but if necessary I might settle for 120x25.

It must be a PWM fan. It should be capable of between 110 to 125 CFM at its very top end. It must not have a problem with motor-whine -- whether it runs at 1,000 or 3,000+ RPM. Preferably, better if it didn't need 3,000 to get 125, but if there is to be noise, it will be almost entirely air turbulence.

OF course, MTBF 50,000 hrs is OK, but it would be nice to have 100,000 -- even if an estimate like that has a noticeable margin of error.

I don't think they're worth $20+ which some people pay for them, but I got some Gentle Typhoon AP-14s for $12.50 a pop (bought 10, should have bought more!) which is entirely worth it to me versus paying $8+ for a far inferior fan. In radiator applications in particular, most fans suck. Not the GTs.

1. The Scythe GTs have higher quality ball bearings - they are inaudible to me at 3 ft, unlike cheaper ball bearings. Comparable to a good sleeve bearing but much more durable and can be used mounted horizontally.
2. The blade design pushes more air, quietly, through high restriction areas like radiators. Good static pressure.
3. MTBF is better than cheaper fans. Double at normal operating temps. 100,000 h / 35°C or 60,000 h / 60°C (your cheaper fans aren't rated at 60°C...)

Now this is a totally subjective measure, but the first impression I get when picking one up is it is HEAVY. Like, twice as heavy as a normal 120mm fan.

 

[BrightCandle]

The gentle typhoons are basically 4db quieter than most fans on a radiator at a given airflow. Or to put it another way you can get about 50% more airflow at the same noise when using low rpm speeds. That is an amazing advantage over most other fans. Compared to the worst fans they are 8db quieter. They really are that incredible for water cooling.

Like power supplies, fan-weight can suggest a better motor.

 

[Tweakin]

Wow! Thanks!

FrozenCPU has almost 300 of them in stock...$20 each.

I just tried them out and they are hands down the best 120mm fan I have ever used on my rads!!!

The Panaflo FBA12G12U meets all your requirements except for PWM.

http://www.performance-pcs.com/catalog/index.php?main_page=product_info&products_id=3142

Fan Size 120x120x38mm
Input power 6.12 Watts
Rated Voltage 12 V
Hydrowave Bearings
Air Flow 114.7 CFM
Rated Speed 2750 RPM
Noise 45.5 dB(A)

I've used the low speed version in builds since 2003 and they've been fantastic.

And what are its characteristics on a radiator? Basic radiator airflow verses Db as defined at (http://www.xtremesystems.org/forums/showthread.php?223391-Fan-Testing-Part-2-(Retesting-Noise)). Without an actual true test we just end up with manfuacturer stats, and based on the tests done so far we all know the numbers manufacturers provide are totally worthless.

But the fan I "need" must be a PWM fan. There are circuit diagrams available -- probably at Overclockers -- for turning a 3-pin fan into a PWM fan. So you end up buying diodes and resistors and troubling yourself with a soldering iron.

There are also two devices which HAD been available from resellers: the Nanoxia PWMX converter-cable, and a Sunbeam-tech PCI converter device which provides either manual fan control or PWM control to two 3-pin fans. the PWMX seems to be no longer available anywhere that I can find; the Sunbeam has terrible customer reviews: it gets hot; it stops working -- any number of reasons.

According to your link, the Panaflu U1A is 2nd only to the Delta in CFM on a radiator.

The static pressure on the Panaflos is pretty good, especially if you are using a high speed one on a dense radiator. However, It is not as optimized as a Gentle Typhoon. However, they are higher output than the majority of GT fans. I mainly mentioned it because it's a 38mm thick fan that delivers over 110 CFM at ~2700rpm, as requested.

You don't see them in many modern roundups since they are an older product.

Here is the U1A that I linked previously on a radiator:

As you can see, the best former there is the San Ace but it's expensive: http://www.amazon.com/Sanyo-109R1212.../dp/B008RTEJ1W

Here is the L1A low speed model that I've had running for a decade:

Graphs are from the following thread (Older benchmarks so not as thorough as your link)
http://www.xtremesystems.org/forums/showthread.php?171661-Fans-Fans-Fans-XS-Fan-Review

But the fan I "need" must be a PWM fan.

What is your specific need for PWM? None of the fans in my desktop are PWM but my ASUS motherboard can still control fan speed. It can manage via PWM or direct voltage regulation.

My personal quest for a PWM is also explained in a thread about "Cougar Vortex 120mm" fans.

I'd dabbled considerably with add-on fan-controllers promising automatic thermal control -- with some degree of frustration or disappointment. It's an extra layer of hardware, addition of complexity, etc. etc. So I adopt a KISS principle strategy.

Mobo fan ports are limited depending on what you spent on the mobo. Sometimes, there are defective ports -- in my case, the 3-pin fan monitoring on an available port. With an adapter like the Swiftech 8W-PWM-SPL-ST (up to 8 fans) costing ~$10, you can control the fans from the PWM CPU_FAN header while powering them directly from the PSU.

That should explain it. Anyway -- the other thread explains a "mod" I'll make to use a 140mm PWM for a 120mm fan exhaust port. Some might think it "Kludge-ey" or clunky. I think it will work.

Ah, I hadn't seen your other thread

Best of luck.
