Triebwerk Here!

[MagisD]

Nothing wrong with yates or push/pull for that matter on any fan, just keep in mind the extra sound sources will increase noise level:

For example one fan that produces 45db on a radiator.
3 fans = 49.8dB
6 fans = 52.8dB
etc..

Here is a handy little calculator for playing around with that:

If you look at the noise vs. CFM charts, I'm not sure push/pull is nessarily better than a single stronger fan though. If we're having to step up 3 dB for push/pull, alot of fans could get a good 45% more air flow at higher volts for 3 dB more sound. So, you may get more performance from a single stronger fan than two weaker ones in push/pull...it may have a different sound quality though..

Damm now I can't decide between 36 yl petra's red led with shrouds and 18 Gts withs shrouds on 6 rads ;-)

Heh, everything that TFC produces is an overpriced POS.

Just wait til you have some run-ins with mr. mario the president. He's a colorful fella.

how can you have a run in with him when he doesnt respond to emails or postings he avoids everyone at all costs.

Oh thats easy. Just make a post that exposes their customer service for what it is, and he'll be PMing you soon and setting off the 4 letter word filter like a fox in a henhouse.

Mario dosn't have a forum account, thats half why over people post new products.

[century child]

I have had nothing but good experiences with Feser products and customer service. Emails were always responded to in a timely manner and their products are definitely not pieces of ****. Anyone who says that has not used them.

I'm no fanboy by any means. Just stating my experiences with the company and its products. YMMV.

i have yet to get a pm from mario, and i think i did my fair bashing at them.

then again i realized a lot of people find me intimidating.

[skinnee]

intimidating.

I'm not sure thats the word others would use.

Done more than my fair share of non constructive criticizing of Fester products as well, no PM here either.


skinnee, I think his soapbox is "growing" again.

[RADCOM]

Why are people here complaining about price when some have started paying astronomical prices for fittings and tubing? Bottom line is this fan good value for money?

Wow, bookmarked. Thanks that is really handy!

I just thought you like playing Santa by sending testers small truck loads of watercooling parts you've become bored with.

You and Hondacity both!!

Looking forward to your test Matin, I was kind of disapointed on my test setup, but as time was limited, I was only able to compare them at 12 V.

does he not have an email either? Does he not respond to emails through feser the website either? didnt think so nothing against you bentleya....just the feser people alone. I guess I can assume he does not have a computer or know what it is

Sorry , but a little information, the email you send though the feser website gets sent to martin, mario has a complete different email address.

If you add them on skype or msn you add martin, unless you hyave mario's personal account.

Well, well, well... For those who keep some interest on upcoming fans from TFC, i've just found the official website: http://www.tfc-triebwerk.com/

[SNiiPE_DoGG]

that webpage is a bit of a misnomer isnt it? seeing as the triebwerk actually sucks bigtime on radiators.... the web design is kinda cool though

[wondergod]

I spent 35 bucks on a fan once.....


and now I have herpes.

"Just found"?......I..don't...think...so

Agrered, i got asked to post it and i did'nt if you really found it you would of posted in about a month ago, when it first went live.

[Stealth42o]

$35??!!

I don't care how good they are. I got three 120.3 in as push pull config.

Sooooooooooooooooo 630 for new fans. SURE

[Martinm210]

FYI, what I did get done on testing.

I think the sound quality is good, they definately have more of a 25mm fan motor sound. I think the fan blade is just less agressive than some others, so you have to spin more RPM to get the same CFM/pressure level. The yate curved blades are actually a fairly aggressive blade pitch, but that's all a factor in noise level/quality as well. I noticed this same thing with other fans, the more straight gentle blade type fans had a different sound but generally didn't produce as much CFM per RPM. I don't think that's necessarily a bad thing though...it's more like the gears in your truck or car. Is 5th gear always the best gear? No, there's an ideal blade pitch for probably every CFM and RPM level. This is what I see in alot of fans too, they tend to have their own little specialized areas of being optimal and CFM/RPM is no different than gearing and generally something that's a bit of a give and take with noise level and particularly with noise quality/tone.

Here are the videos I worked up for your own comparison to CFM. Just keep in mind CFM does not necessarily equate to radiator performance either. When I did my earlier fan testing the UK3 produced more CFM per RPM than yates, but in radiator testing it appears the larger fan hub diameter creates more dead spots and this relates to less performance per CFM.

I see qualities in all of them. The Triebwerk have a very smooth sound, not necessarily the lowest level, but the sound is predominantly air movement and lower tones on the motor. The GT makes the least blade noise, but this also makes the motor noises much more pronounced and buzzy. The San Ace has a pretty strong ticking that I don't care for at very low volts, but it really does well at higher speeds.

Visually, I think I like the Triebwerk fans best, followed by the San Ace. I just like the larger industrial look to them. But that's all pretty subjective, I'd suggest looking and listening to the videos and make your own judgement. When testing these fans on the Monsta radiator recently, I liked the sound of the Triebwerk better than the Yates or UK3. I also played around with some Koolance 140's, and they do perform well, but the noise wasn't something I liked.

When it comes to fans, I find it pretty hard to quantify quality. You really almost need a full set of three fans and test them personally on a radiator to really understand if you'll like them or not...

There's too many variables to pin down and then there is the biggest factor "Noise Quality" which is different for everyone and very different from noise "Level". This is why I resorted to the videos, it's probably the best way to present the sound tone and gives every one person a chance to make their own judgments...not what I or anyone else likes. Hopefully it at least gives you a rough idea what you might expect, although I think ideally it would be 3 or more mounted on a triple radiator to give the full noise response. I find some fans tend to have more harmonic noises between two fans than others. Some fans seem pretty good with just one running, but when you run 2 or 3, you'll start hearing slight RPM variations that create a fairly pronounced harmonic noise that's annoying as well.

Pretty hard to test fans...that's all I can say...and I've had my filling and them some already.....

Great testing, Martin. I already ordered me 3 of the TK-121... they should arrive during the first week of July.

[neonatas]

Seriously, the constant ing about prices on this forum is getting stupid. I honestly dont give a crap what a item costs, as long as that item does what i expect from it. Thats the only thing that matters!

these fans perform worse than a $7 yate loon according to the testing done by martin - understand the issue with the $35 price tag of these fans now?

[Sadasius]

Exactly! Does it make sense to pay for something that performs worse then a cheap fan? Not at all would be like ingoring the 5870X2 for $200 and picking up a 7800 GTX for $700. Seriously it's that F$#%ED!!!!
