This, in essence, is what I said in my previous post.

Well put as always, DuckieHo.

It does you no good to be dishonest with your own findings.

I think the best approach would be to take anybody else's findings with a grain of salt, a healthy kind of skepticism, if only because of the uniqueness of his own situation. Some users may find that their results will coincide with you own; others may be way off.

Computers are not homogeneous machines; this is especially true in the world of custom PCs. Even in a laboratory, where variables are controllable, any little change in conditions will result in a "skewed" report. Besides, even in the most ideal kind of situation, such results aren't exactly "real-world" either, because, by definition, they are idealized. The real-world is not a static environment like a laboratory is.

In conclusion, when it comes to all kinds of equipment, do your own tests. Get your own results. Your findings will not be the same as someone else's. Understanding this is the most important principle, I think, when it comes to any kind of real-world usage of any kind of machinery.
Naw... getting a standard benchmark is better. A fan has the same performance curve regardless of where it is used. The end user can then figure out their sweet spot on the fan performance curve. I rather get a few fans that generally meet my requirements and testing.... rather than getting a lot of fans randomly.

There only few major variables with fans.... CFM, static pressure, dB, and noise frequency/pattern. The first three can be plotted. The last one can be recorded (check SPRC for samples).
Once again...

The reason I dispute this point, to whatever degree, is that everything is also interacting/reacting to its environment. The environment is organic, and so would the results. This is also why I insist that one's own equipment is often the only reliable benchmark.

"Standardized" benchmarks do have their place, though. A guide, perhaps. But always should there be the proviso that, in the real world, or in another set of circumstances, the same results are never guaranteed.

Absolutely agree on this, however, when you only have $XX to spend, it would be nice to see a list of options where everything has been tested using the same conditions so that you can make an educated decision on what will best match your needs as far as performance/noise/cost.

Example would be 3DMark06.... getting a score of 16000 means you should do well in games. It is not a guarantee though. However, it serves it role as a benchmark by providing a common comparison across systems. If another user has similar setup, they can expect to get similar performance. Benchmarks serve their role as a guide.

Aye, true.

That is the big drawback. Money. It takes lots of time and money to do testing. This is the true value of "standardized" benchmarks. But your own results cannot be guaranteed to match these standardized tests, whether for better or for worse.

Thread Starter 
Those are some salient points guys and very much to the core of this thread.

The only thing Vapor's data will provide is a guide by which to compare fans. Obviously each application introduces unique elements that impact the performance of the particular fan.

I will be doing the updating later this evening as I am too busy ATM.

Fans are something I am really keen to be all knowing about...I do a lot of random fan buying (lol @ Duckie Ho) and have tried almost all the fans from years past--but dozens of very interesting fans have some out recently I really want to buy and try.

When the first "golfball" fans came out I figured for sure they would be the king of quiet cooling...but like all things new they were too expensive for me...

I have no real taste for over-priced wares--I generally look for a good price/performance ratio and buy midfield.

SilenX fans are my one and only exception to this rule (well that and ThermoChill radiators ) and I am willing to be taken to Skool--by a guru--as my true aim here is to learn and share my knowledge.

Heck I even bought some HW Labs rads....this old dog CAN learn new tricks.

Those Sharkoons fans? I still hear they are good... but not many resellers. Fans are too expensive to test though when there are other things to test. I have owned about two dozen different types in the last 3 years.
