World greatest fan roundup part 1

[Steensen]

Hi guys.
Here is the first part of a series of articles, that eventualy will be the worlds greatest fan roundup, with more than 50 diferent fans being compared.

It's written in both Danish and english, and the following articles will also be written in both languages.

Here on ComputerGEIL.dk we will in the upcoming months be reviewing a bunch of computer fans. We will be testing them to the limit, and for the first time, you will be able to select your own personal winner.

We have borrowed fans from Denmark to Hong Kong, and from fan producers like AcustiFan to Vantec, so there should be some for every taste.

This is the first initial article, which will tell something about what is going to happen in the next months here on ComputerGEIL.dk.

Well someone has to do this sooner or later. I mean, fans are something that are very hard to compare between each other especially when each fan was reviewed by something else. Plus, most of the time, the specification from the manufacturer aren't quite accurate since each of them have a different way of testing their hardware. Now, which this uber roundup, buying a new fan wouldn't be easier! Can't wait :D

What are you going to test the fans with?

Now that is a whole different story, and this story will be told in one of the next upcoming articles here on ComputerGEIL.dk, and in that article you will be able to read about the test equipment, and which test methods we are going to use, to test the different specifications on the fans.

I realy hope they do a pressure vs CFM test/graph of all the fans.

Free flow CFM is kinda pointless.

For some reason I'm really pumped to see these results - especially when choosing for watercooling.

exactly, but i somehow thing they wont be testing this.

i also think they arent going to be using very man perfomance fans like delta/panaflo/high end sunons. i think they will be sticking with mainstream fans like what vantec and all those other pc cooling companies put out which are crap.

yeah, i hope your worng, but your probably right.

I want to see a comparison of Delta/Panaflo/Sunon/Papst/etc side-by-side on the same test bench.

I would imagine that the company with the highest static pressure in the 120mmx38mm would get a little more business, at least from me.

Would you be needing a translator? I don't speak Danish, but I can use your translated stuff and put it in more laymen terms. Let me do this one, I'll show you what I mean.

Edit: I'd suggest maybe doing a few other tests (the poster above's idea of pressure vs CFM sounds good) as well. And maybe making little notes about how you felt the fans were in real world situations, such as "I put my ear to it, and can hear a slight clicking motor noise".

Here's my translated version (taken from your English ones). If you'd like, I would be willing to do this for every one of yours, free of charge, just hit me up with a PM.

World’s Biggest Fan Roundup, Ever – Coming Soon
Vol.1

Here at ComputerGEIL.dk we’ve got something special prepared for you. In the next few months we will be testing, reviewing, and giving a roundup of a TON of computer fans. We’ll push them to their limits and then you can decide for yourself, which fan is the best for you.

We’ve borrowed fans from Denmark, Hong Kong, and everything in-between. There is a wide selection of fans, from famous makers like Acoustifan, and Vantec, as well as many other fans; there’s a fan for everyone. Whichever fan you ever thought about buying, it’ll probably be in here.

This is the first of many articles at ComputerGEIL.dk which is a small teaser about what’s going to be happening in the coming months.

Why is it necessary for a massive fan roundup?

On almost every fan available, the producer company has listed some statistical information. For example, they may tell you the noise level (dBA), the rotational speed (RPM), and the power consumption (W).

However, each different company tests their fans in different environments, with different equipment. This can lead to varied and skewed results.

ComputerGEIL.dk is prepared to test all the fans the exact same way, with the exact same equipment to give an accurate reading of the specifications of each fan.

What are you going to be testing?

We’ll begin our tests with the easier measurements. Minor League stuff you could say. We’ll measure how many rotations per minute (rpm’s from heron-in) at 5v, 7v, and 12v the fans will run at, as most standard users can easily run their fans at those levels. For instance, one fan might run at 500rpm at 5v, while another runs at 1000rpm. This can be a quick indicator of the airflow, and noise level of the fan. But remember, this is only an indicator, as there are many exceptions involved with fan technology.

The next thing that we will be testing will be the push of the fan. How much air can the fans actually move? Once again, we’ll do the comparison at different voltage levels since it can change drastically as the voltage is changed. We will also be looking at how much air each fan will push when running at the same rpm (not all fans run at the same rpm at the same voltage) with a specially built device that allows us to measure the airflow of standard fans (80mm, 92mm, 120mm).

Furthermore, we will be looking at if there is a connection between the amount of air moved, and the noise level. Is it uniform in all fans? Of course not. We’ll be showing you all the data so you can try to find your personal ideal; lots of air movement, with whisper quiet operation. Does this type of fan really exist? You’ll have to read on and find out…

The next test we’re going to do is to measure the noise level in decibels (dBA) of all the different fans, once again at varying voltages.

The next test is more long term. We will be running the fans continuously after the first test, and testing them again once a month. By doing this, we will be able to gain an idea of the stamina of the fan. There’s no point in buying a whisper-quiet fan that only remains silent for a month, now is there? In fact, we’re going to push all these fans right to the end, and run the tests for a whole 6 months! That way, we can hopefully crown an undisputed winner.

How many fans are we talking about then?

Without ruining the surprise, we can tell you that we’re talking about more than 50 different fans right now, and more and more are being sent in for testing. So there’s a high possibility that anything you may be looking to buy, or already have, will be reviewed. Maybe you’ll find out that the fan you’re always suggesting to others may not be the best after all. This could be a real eye-opener for everyone.

What test equipment are you using?

Now that’s a completely different story, one that will be told in an upcoming article. So visit frequently and stay tuned to ComputerGEIL.dk to find out the latest on this massive fan review.

So pick a fan, and find out how it ranks, on the World’s Biggest Fan Roundup, Ever.

About when will a new page be released?

[FLMJIGGY]

Look at the date...... If I'm correct it has taken them 3 yeasr... so far... maybe they're making every single fan available?:p:

[Ubermann]

Tell me more about year 2010 jiggy..

Does the cars fly yet ?

[SoundWave]

I'm sorry about the date, but we have to set the date back because we don't want the article on the front page in english.

Me and the author of the articles (he writes Danish, I'm writing English) are going to do some last modifications to the test station next weekend (14-16 of July), and soon after that, the next part of the article is being put online, after SoundWave has approved them.

@Steensen: I didn't realize you were the author as well.


So are you going to be testing static pressure? This would be a very helpfull figure for watercooling enthusiasts.

Wait, and you will find out soon enough. ;)

Hi!

I'm the author and the person who does this test. I just want to say that part 2 is coming really soon. If you read Danish you can read part 2 now, but for the rest of you, you'll have to wait at day or two more. Steensen is translating the article as you read this. So be patient. We are working really hard.
