Passive Athlon XP cooling experiences?
 

I'm playing around with a new AMD setup (new xp1700+ juihb and fully featured chaintech nf2 for 70 euro... i just could not say no :-) ), and being bored of noisy systems i'm trying of cooling it passivly.

Currently, I'm trying 150*7 (1050mhz) at 1.39vcore, and it seems pretty stable. Stressed with normal apps (bios, memtest) gives a temp of 70 - 72 degrees (diode, not socket).

That might seem hot, but a tbred b should be able to run stable up to 85 degrees.

I've set shutdown temperature to 85 degrees, the lowest i can choose.

Heatsink is a copper Coolermaster Aero 7, certainly not the biggest socket a on the market. Does anyone know of a cheap, but huge socket a cooler?

Anyone else got experience on passive tbred b cooling?

aaah there's my missing Aero 7 :p

well if you are going for passive cooling, might make one of your own, or add a very very silent 40mm fan to that setup, it will drop the temp by 10-15°C

Well, adding a 13dBa papst NGL at 5V would drop the temp by 30 degrees, but that's not the point. Even if you use a completely silent fan, you can still hear the air blowing, or the fan slightly vibrating against the socket, or dust piling up in the heatsink, or... Completely passive is just way more fun. :)

Yes i'm nuts, I've got a loud fridge 3m from my bed, but i won't alow my pc's to make the slightest noise. : )

40mm fan @ 5v won't make noise. no noise. none. nada. as in. silence.

And not as in jmke went too many times to ibiza?

jmke went to ibiza once, only entered 1 disco, payed €50 to get in, stayed 45min.

your point being?

ok, i'll try it out

even a low profile 60mm fan @ 5v is very silent, but that might be pushing the envelope for 'ol richy ;)

hmmm, 7.5*166 (1333mhz), 1.4vcore and 40mm at 5V = 76 stressed.

Doesn't seem to help that much, let's see whether it can keep it below 70 degrees if I run at 1.38vcore and 1050mhz. : )

-edit-
Hmm, the 40mm at 5V barely seems to make a difference. It's exactly as hot as pssivly cooled at 1050mhz.

I'll try sucking instead of blowing.

Place your bets..
How will that hardware survive ?

My guess, +-2 weeks :), if it's lucky.

My via epia runs fine at 90 degrees. My P3-S M usually runs between 70 - 80 degrees. I can't see why an Athlon XP Tbred won't survive 70 - 75 degrees, it's certified to run up to 90.

maybe you can try to remove some fins from the heatsink so there is more are between the fins, that would be better if you'ld work fanless

The heatsink is not my property. :)

And even if it was, i wouldn't like to ruin it.

Buy that uber zalman case. it weighs a ton, costs a ton, but it's quiet.

You'll need a big heatsink with large and spacious fins that, when mounted, are vertical. A global win heatsink, a CAK** (don't really know anymore) fits the bill. But I wouldn't trust it ...

Innovatec has some passive ratiators (a tower of 50cm high) but you'll still need a pump.

and a pump is not really silent.

I know the solution.. hook your PC up to the fridge, 1 sound-source, problem solved :)

Can't you mod that heatpipe heatsink for the PIV and put it on your amd?

what are you talking about?

SP-94 ?

I think that it's that one.

edit: yes the SP-94

Looks interessting, but I'll think I will wait a few months and then buy a 64bit setup.

I use 8rdaVcore 8B and only time I leave my pc on is when I'm downloading something.

When downloading (not very heavy task) I could go down to 1.075vcore with 1325mhz.

Playing mp3 with winamp 2.91 surfing with 3 IE and downloading it didn't chrashed so fine by me :^D

1.075vcore?? Wow... i thought the silicone architecture of a athlon core needed at least 1.3v to properly conduct electricity.

My tbred b is unstable below 1.37v.

Well my fsb was only at 108mhz

This allowed me to run a 80mm sunon @5V and got temp of 33°.
Leaving it alone for a long night could mean getting even lower (bus disconnect does that :) )


I'le try to give u a screenshot one of these days
