Twittersearch on fan noise.<\/p>\n

\n

I believe i will have to bring back my Macbook Air. the fan<\/strong> is making constant noise<\/strong> and runs at 6\/7ks rpm…not good.<\/em><\/p>\n

The fan<\/strong> on my Newertech MiniStack 2.5 is failing for the third time. I really can’t say enough lousy things about it.<\/em><\/p>\n

Solved one problem with iMac now have loud fan<\/b> noise<\/b> which is driving me crazy – !!!!! Ahhhhhhhhhh can’t stand it!!!<\/em><\/p>\n

The noise<\/b> of my fat PS3’s fan<\/b> drove me so mad that I got a slim.<\/em><\/p>\n

XBOX360turn down the fan<\/b> noise<\/b> please.<\/em>#xbox360<\/em><\/a><\/p>\n

New northbridge fan<\/b> ready to install. The old one was driving me nuts with noise<\/b>.<\/em><\/p>\n

I HATE MACBOOKS!!!!!!!!!!! Why does the fan<\/b> freak out and make loads of noise<\/b> every time I try to film something?!!!!!!!!!<\/em><\/p>\n

I hope my laptop fan<\/b> thingie isn’t dying….I hate when it makes the odd noise<\/b>….<\/em><\/p>\n

Hm. My mactop fan<\/b> shouldn’t be making that rattling noise<\/b>, should it?<\/em><\/p>\n

My laptop fan<\/b> is making a buzzing noise<\/b>. I shook it, and it just got louder. Just like a baby.<\/em><\/p>\n

Checking on obscenely loud computer fan<\/b> noise<\/b> I’m tired of listening to. Time to crack the case.<\/em><\/p>\n<\/blockquote>\n

etc. Needless to say my Dell laptop is doing the same too. All computers and piece of hardware start being silent and after some use they all are getting damn noisy, thanks to this weak design that is a cheap fan blowing hot air on an expensive silicium chip to make the temperature drop. Isn\u2019t it stupid?<\/p>\n

I know, we can\u2019t really get rid of them for now, and the smaller fans are, the more they make noise and are unreliable. Hence the problem with laptops.<\/p>\n

On the other side by making less powerful chip we can be fanless, like smartphones and netbooks are showing it. But of course we lose a lot of comfort (forget about the 24\u201d screen and forget about the fast as \u201cimmediately\u201d<\/em> when loading a heavy web page).<\/p>\n

\"CPUs\"<\/a>
Good old silent days, please come back thank you.<\/em><\/p>\n

TDP<\/h2>\n

To understand how much we are close \u2013and yet far away- to solve this problem and have both silent and powerful computer there\u2019s a measure unit: TDP Thermal Design Power (in Watt). It represents the maximum amount of power the cooling system in a computer is require to dissipate. The number is usually 20 to 30% lower than what the chip is able to output when really stressed out (video encoding, games). So you always need to have more than what your processor can dissipate. Of course the faster the cpu is, the bigger is the TDP. <\/p>\n

Full List of CPU power dissipation<\/a> (long loading is long). Wikipedia, I love you.<\/p>\n

First there\u2019s a huge dynamic: from the single core Atom running at 1.6 GHz you can find in netbooks at less than 3W to the quad core Core 2 Extreme QX9775 at 3.2 GHz rated at 150W.<\/p>\n

To dissipate a cpu passively with a simple chip-sized radiator it needs a TDP inferior to 10W. In a really compact environment like a phone it needs less than 3W. <\/p>\n

If you want to passively without any need of fans to dissipate a typical 2010 desktop computer at around 65W\/90W with a midrange graphic card, you need like 25 Kg of steel attached to a radiator on the CPU. Temperatures at full charge are as high as 90\u00b0C (194\u00b0F) or more on a finger nail-sized surface. Don\u2019t forget that we need to dissipate three literally burning chips in a computer: the CPU, the GPU and the Chipset which is responsible of all the interaction with components.<\/p>\n

\"G5<\/a>
25 Kg of thick black anodized aluminum does the job. But man!<\/em> <\/p>\n

Yeah it\u2019s kind of insane.<\/p>\n

For the rest of a configuration though, the problem is already solved even for the high end market: sound card? No need of fans. HDDs? Not really. SSDs? Not at all.<\/p>\n

Because progress of making cooler chip is always matched by the progress of making them more powerful, we always end up on the last trend because manufacturers (basically five companies: AMD Intel Nvidia Motorola IBM) would say that \u201cthe market decides and people want more\u201d<\/em>. Hopefully they now know. They stopped pushing the thermal envelope and the clock rate<\/a> to focus on resource management, adding more core for the same energy output after facing some problems of..<\/p>\n

Reliability<\/h2>\n

A really important parameter in being satisfied with a computer or any digital device is to have the less maintenance possible to do on it. With the extreme temperature of today\u2019s chips and the fact that they need fans, these weak points getting clogged and making noises or simply killing machines by dying, reliability is not better but worse than 10 years ago (is the fan 3 not working well or is my watercooling pump dying?). And it requires more management than ever before. <\/p>\n

Before the Pentium and the 100 Mhz barrier, computers were not requiring any special care. Since circa 1997, fans are obligatory and IT help desks became Dissipation Garage.<\/p>\n

In a fanless world, machines are maintenance free. They are virtually more stable than a rock in a field. They can be covered of dust like your media center under the couch, no problem. All year long, you don\u2019t hear anything and you don\u2019t have to bother at all<\/em>. You know there is not going to have any problem unless something heavy fall on it or if there\u2019s some water damage. Otherwise you can forget about it and that\u2019s the beauty of the fanless design. You know it. Your TV. Your fridge (almost). Your Hi-Fi. I want that in the computer world. All around me. But there\u2019s more reasons for going this way.<\/p>\n

Sustainable development and human rights<\/h2>\n

First, we need to make these hundreds of millions of machines to be useful as long as possible to avoid stupid waste. Having fanless design all around would make it easy because computers usually come out useless because of the weak fan design. If they could work without any problem and any noise I still would have my old machines, computing for a cause<\/a> 24\/7.<\/p>\n

Too much electronic waste. Way too much<\/a>. Discarded electronics represented 5 to 6 times as much weight as recycled electronics, polluting entire region of the world.<\/p>\n

\"Electronic<\/a>
Think about it next time you use your phone or your gamepad.<\/em><\/p>\n

Second, we all know and don\u2019t want to admit it that all the digital devices and computers are made by hands by 16-18 years old Chinese women working 90 hours a week<\/a> (more at Kotaku<\/a>). It\u2019s called slavery and it makes me sick just to think about it. Especially whe
\nn as you gadget lovers, my eyes sparkle when they see a nice and new piece of hardware.<\/p>\n

It has an awful human cost. And I want that to slow down and even stop some day. I want these girls to use what they actually make. I want them to connect and learn as much as I did and do, thanks to the magic world of computers.<\/p>\n

 <\/p>\n

So to resume in two lines it\u2019s either:<\/p>\n

more power=>more power consumption=>more heat=>more noise=>less reliability=>more waste=>more slavery<\/em><\/p>\n

or<\/p>\n

more efficiency=>less power consumption=>less heat=>less noise=>more reliability=>less waste=>less slavery<\/em><\/p>\n

After decades of the first, I want the second for a while. Please? <\/p>\n

So when I\u2019m said that as a music producer I\u2019m legitimately anal about the noise that machines make, it\u2019s not just that. Really. <\/p>\n
