Don't be shy, I own 3 Feser XChanger 360s and now 3 Monstas! :D Was it the best bang for my buck? Most likely not, :shrug:. In reference to the Monstas, when implemented into my current and ever changing build they most definitely will be absurd! That's okay, I like absurd things, even if they are not a very good idea (see Darwin awards... :rofl:). My point is I like Feser radiators and at the end of the day, even if someone else has all the right reasons to despise them, it's good that we at least have so many choices and individuals will always have preferences (this comes as just a thought, not arguing that anyone has suggested the opposite).

Now my preference for Feser radiators may be due to blind brain washing via shiny things and an erroneous mentality to assume more expensive/bigger radiators must be better or (and I tend to assume this by default most of the time) I'm just not horribly intelligent.

Exactly! I currently have ducts going from AC unit to server/computer closet then hot air pulled directly into the attic... and the mini-fridge next to my desk has it's share of beverages of choice. ;)

Last, as always thank you martin for your diligent research and focused effort. I eagerly await further reading!

That's enough of my "hot air" for now... :)

HEY I AGREE even with bad customer service on fesers part I still like their radiators two quads and one monsta they perform great like you said not the best bang for the bunk though on monsta but its cool to see a hyooge rad on the outside of the case.

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.

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..:shrug:

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

how can you have a run in with him when he doesnt respond to emails or postings :mad::D 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.

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. :shrug:

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

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


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

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?

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

You and Hondacity both!!:rofl:

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 :rolleyes: 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 :yepp:

Sorry :shakes:, 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/ :up:

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

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


and now I have herpes. :(

:rolleyes: 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.

Sooooooooooooooooo 630 for new fans. SURE

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...:shrug:

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..:eek:...:D

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