General Fan Performance Guide

Lars Olsen writes: "As a complementary article to his comprehensive General Heat Transfer Guide , Dave Smith has written another great article for Amdmb.com called General Fan Performance Guide. This is an indepth guide to the performance of the fans we have in our PC's. Here's a quote: 'The specific purpose of this guide is to take the science associated with fans and translate it into a meaningful document that will allow the reader to understand how fans work and how they apply to computers. It provides a brief summary of DC power and drives. It finishes with an introduction to the concepts of sound generation and measurement.'"

I am not a troll

[Anonymous Coward]

People have a right to know if their Anonymous coward is a troll. Well, I am not a troll.

you want good luck to follow you and your offspring for geneations to come? This troll has the solution for you...

All you have to do is copy this troll onto two to four of the discussion threads of your choice! That's right! Just copy this into a new message and click "post anonymously." That's all there is to it!

Tired of that idiot talking about geek culture! Stick one of these babies on it! And it's good for the economy!

Marge Gentry of Cambridge, Minnesota participated, and the next day she received a large fruit basket outside of her door from a secret admirer. Unfortunately, Marge was hit by a truck the next day, so she didn't get to the Granny Smith apples.

Commander Taco of Hole-in-the-ground West Virginia didn't participate, and he was violated by a group of raging homosexuals. Since the gang was headed by Jon Katz, Taco had no recourse to the law because the entire town knew about their previous relationship. The unfortunate outcome is enshrined forever at goatse.cx.

So if you want to get the fruit basket and not get poked in the bread basket, just copy this troll onto two of the discussions threads of your choice. We could have this place blanketed by sundown!

Plus ça change

Isn't this all kind of pointless?

For me at least, my computer came with a fan. The fan works. Why do I need a new fan? Why do I need to know anything about fan performance when THE FAN WORKS? And if my fan ever stops working, I can get a new computer.

Perhaps for system builders like Dell and Gateway, this type of article can be of some use. But for the average slashdotter, it is too technical and too specialized. And as a great man once said, "specialization is for insects".

The truth is that CmdrTaco and friends are frustrated that both dirty trolls and Ph.D. holding geniuses are posting as AC's, hence tainting the named accounts with a "middle class" flavor.

Heck, there's now even a user preference that sets all AC posts to -1, even if it went up all the way up from 0 to +5.

Wake up Slashdot crew! You have people posting the heat equation on your website within 15 minutes of a Heat Transfer story. Aren't you astonished?

Let me get this straight... (Halloween Special)

[Anonymous Coward]

As if recent events (attacks on the World Trade Centres, Anthrax Attacks) raising our collective conciousness into a state of terror wasn't bad enough, Halloween is just around the corner. Soon, a new terror, a spooky terror, will unfold as the souls of thousands of innocent civilians who died, raise from the dead on All Hallow's Eve to terrorise yawl's neighborhood. And you people have the gall to be discussing fan performance???? My *god*, people, GET SOME PRIORITIES!

The angry souls of the recent dead could give a good god damn about fan performance, instead preferring to wander the areas where they met their untimely ends, seeking out unwitting victims for retribution. By all means, on the evening of Hallowe'en, try to avoid the area around Ground Zero of the WTC, the area near the Pentagon, and the crash site in Pennsylvania unless you don't mind becoming a victim of terror (a very spooky terror indeed), yourself.

You have been warned!

A can't believe no one said this yet

But this story really blows
