The Sound of silence( cool computers)

[Dan]

My stupid PC gives me headaches!
Can I run it without a CPU-fan, with just a heatsink?
Its a 1,2GHz amd duron. Also what is the fastest Intel or AMD cpu that can be run without a fan?
I heard that the AmigaOne G4 has a CPUfan, that is not cool, why?
My A1200 060 50Mhz doesn`t need a fan.

Not likely.... a 1.2ghz can cook up some heat.  I wouldn't dream of taking the big-ass hsf off my 1.2ghz T-Bird.

You could use a Zalman cooler, or some other low-noise solution, though.  

Also what is the fastest Intel or AMD cpu that can be run without a fan?

Not very fast.  I haven't seen a PC faster than a couple hundred mhz without an active fan somewhere.  (now granted, some later designs up in the 400-500mhz range used a large heat-sink on a cpu and routed air from the power supply fan over it...)  But, even then, I've not seen one over 500mhz or so.

I heard that the AmigaOne G4 has a CPUfan, that is not cool, why?
My A1200 060 50Mhz doesn`t need a fan.

You just typed the answer, yourself.  a 50 mhz chip with ~2.2 million transistors (68060) vs 700+ mhz chip with over 6 million transistors (g3/g4).

To run a chip that is that much more complex, you need more power.  (You're not going to run a modern computer on a 50-100watt A1200 power supply, either!)  You add more power, you get more heat.  More heat means you need a better way to dissipate it.  Hence, larger fins, more fans.

Don't know about the AmigaOne PPC but, my son in-law has a Imac II with a 1 Ghz G4 cpu and it has no fan and a dinky heat sink.   My 450Mhz cube has a larger heat sink than his and it's really not that big, and has NO Fan! :-D

Try larger fans running at a slower RPM
This will make things quieter. I am trying to arrange the import of some GMC Noblesse SE cases to the states. These cases have soundproofing throughout the case. All the drives are isolated with rubber and teflon. Even the Power supply is equiped with dampers. makes for a very quiet PC or AmigaOne/Pegasos

Or you can buy ASAKA soundproofing for your case.


The heatsink fan on the Amigaone G4 is anemic to say the least very puny. Not much noise or heat.
But I recomend you replace it with one a little more robust.

Try looking at this heat sink with no fan (large case fan is required thought)  Zalman

Bought me a Hush and love it.

No fan, quiet HD, I leave it running all the time (low power too) and even under load (emerging under Gentoo) it doesn't have any problems.

What do I call it?  It hath been so named: "amigatoo".  That's it's net name.  Based on the idea that, according Amiga Inc. at one point, if I bought Amiga Forever, any computer I run it on is an OFFICIAL AMIGA!

So it's an Amiga.  An Amiga Hush PC.

 :-P

The best and silent Ventilators are here

Verax

They have PSU, CPU and VGA-Cooler

BTW I can sleep in front of my PC...so silent

The Hush is pretty cool, so is the Tranquil PC......  The same computer in a different case. :-D

Still cool though.

Look also for the silent coolers :

http://www.arctic-cooling.com/en/
I'm using the Artic Cooling Cooper Silent with a Athlon XP 2000+ and it's very, very silent (not complete silence but very quiet.

No its webpage, it's rated at 20 dB. Now you know that other cooler with 20 dB should be quiet (at least for me. And I also value the silence on a computer  :-)


Figure out it your PSU also makes noise ...
In that case, look for a silent PSU also.

(damn PC technology! Speed first, comfort later)

BTW : do you know how to post a follow up on these forums instead of reply like i did now ?)

Thats exactly what the iMac G4 does - it has a fairly low speed fan running at the top of the dome, pulling air up through the base and around the inside metal casing. Heat pipes carry the heat from the cpu out to that case. They're quieter than the HD itself.

The convection iMacs have the G3 in contact with a rather massive plate of aluminum that's also connected to a mesh just on the inside of the case - most of the air that passes up through the machine goes through that mesh. Same kind of idea - lots of air, moving slowly. instead of smaller patches of highspeed air.

Hmmm....fans....go for the Zalman Flower...have one at home as its as close to silent as you can get. You will see why when you have a look at a pic of it.

PSU....quietpc.com   Got one yesterday for work and you can hardly hear it.

CPUs running without fans....Via have released their x86 processors...the 533 and 800 MHz ones can be used without a fan. And they are dirt cheap

[RedWarrior]

I've been researching this one as well... http://www.endpcnoise.com/ has some good solutions....

The Zalman flower looks interesting, but takes up a lot of space in your case and also exceeds Intel and AMD's weight guidelines for heatsinks...

This is exactly the type of thinking we need for Amigas.  The complete solution not just a Motherboard.  Whats wrong with specifying a mininum spec SE system a nice looking case which is dead silent (ie Segate Baraccuda H/D, Radeon 9200 (or even 9600 when the price is right) both have only passive heatsinks, Silent PSU, etc.

I'm looking forward to a Hush type system (see mentioned elsewhere) with an Amiga iATX board in it (G3 FX/GX will do!).  I've got case designs drawn up already if anyone is interested in producing 'em.

And all these comparisons between PPC vs x86, never compare like with like.  Lets see a comparison of G3/4 with Mobile CPUs like the Pentium 4-M and Pentium-M.  I'm possitive you would see Price/Performance ratios that are very close...(IMHO!)

BTW was I dreaming about iATX Amigas, I'm sure I heard this from Eyetech and now I can't find any mentions at all!  Please someone find me some info so I know I'm not completely insane!   :-D

Dont even try that... it will fry after a while. There is more silent coolers out there also, which still does a good job at cooling it down.

Though... if you underclock it and set it to lowest voltage... then it should work fine.. even my TB 1400 did if i clocked it down to 600mhz using lowest core voltage... i think it was 1.0-1.1 or something

And yeah... as EgonSpenglerUK said.. Via has some nice chips that run fine with just a small heatsink and they are cheap.. You get both miniatx motherboard with integreated audio, gfx, network for less than the price of a modern amd/intel cpu.
