Fanless Duron - Is this a good idea?

[rockhard]

Im just putting together my shopping list for my study PC which will need to be as fanless as possible.

I was wondering if i was to buy a Duron 700 and underclock via the multiplier to 500 and also lower the voltage to say 1.55v would i get away with using a Alpha heatsink with no fan?

Motherboard? Is there a motherboard thats micro ATX form factor that supports the bridge joined overclocking of the socket A CPU?

Any help be much appreciated,

rockhad =)

might work , u can put like a 10cfm panflow that has like no noise,....why would u wanna do this anyways?

Try Passive Cooling. Get a fatty HS on the CPU and maybe a Silencer case fan on there and it should be fine.

Man I dont understand why you people whould underclock cpu's to run them wit passive cooling just to reduce the noise.

Have you ever thought about getting a good quiet fan and sound deadening your case? you wont beable to hear a thing

You said it. Buy the chip and use the stock HSF. Quiet enough as it is, underclocking is just throwing your money away.

 

[pillage2001]

Why underclock??

 

[nickburns]

is the noise from one fan on your cpu worth underclocking it? just use a reatil HSF or something that is pretty quiet and run it at stock at least?

If you really want it quiet just trade your system for a laptop

Here's his reason, although i dont really know if the ambient noise from a PC's taht irritating....

I'm not even sure you can underclock like that because socketA motherboard I OCed on (msi k7tpro2a) only listed 7.5 multiplier and above (up to 12.5) for a 750 T-bird. Anyways, it's not really a good idea, just get a really silent power supply and stick a really quiet fan on your heatsink (maybe run it at 7V) and you won't hear a thing.

The stock retail fans are extremely quiet, and do a very good job of keeping them cool. My roommate's TBird 900 with retail heatsink and fan and the stock phase change compound runs cooler than my TBird 800 with Arctic Silver and GlobalWin FOP32. (Intel stock fans, not so good. They barely blow any air, and the CPU's get up into worrisome temps.) And my system with the case covers on and locked up tight is a hell of a lot louder than my roommate's which runs with no covers at all.

There may be Micro ATX boards which allow multiplier changing, but I doubt there are many of them, and you're almost assuredly only going to find them with an integrated chipset, with onboard video, sound, LAN, etc. If you're only going to be using it for schoolwork, then that may be exactly what you want. If you plan on doing anything beyond the basic Internet and word processing/spreadsheet type stuff, then you'll want a board with an AGP slot to allow you to use a better video card at least. Durons run quite nicely with a TNT2 card.

It's really hard to get away with no fans on modern cpus. Most non overclocker size fans tend to be fairly quiet. I find that in almost every situation, power supply fans are louder than cpu fans. I find that using a giant heatsink, use a case fan, but running 5 volts instead of 12, gives good cooling, but it is almost silent. No need to underclock either.

Man.. my Duron 650 with Antec 303x PS, Slot cooler, and still the fan for the chip is VERY quiet.

My athlon slot is pretty darn loud though. Just deal with the PS fan that should be very quiet.. and get the HS/Fan for the Duron and I doubt you'll notice the sound at all.

Dude, if you want a quite system, &amp; you don't mind doing some mods?? This is what I'd do...
1)use a low RPM 120mm 12v fan, run it @ 7v &amp; good heatsync (With heatsync compound)
2)build an air duct/funnel for maximum air flow. (use cardboard &amp; ductape if $ is tight)
3)enjoy the nice quite, yet very cool system

You know what you can do... bah I can't think with my 4 case fans+delta in an open case comp next to me

 

[urbantechie]

I say go with Passive Cooling and use a Silencer fan on it.

 

[Lord Evermore]

using a fan automatically makes it active cooling...technically...whether it's mounted to the heatsink or not...

 

[ElFenix]

lhampel - thats pretty much what dell does, those are some quiet computers. except for the 1GHz ones. those are loud

thanx for all the replies guys

heh, i like the reply about me studying for school - im 28 so it put a smile on my face (no offence taken )

im actually planning on studying for A+, Network+, CISCO, MCSE.
im just starting on my A+ so got a long way to go though

think i'll try popping my alpha on it and ducting it to the PS intake and get a nice quiet fan to pop in the PS.

Can u guys recommend a quiet PS - I heard that the Enermax 350 was as quiet as they come?

thanx,

rockhard =)
