Passive Tbred B cooling

What processor?
Are you underclocking?
undervolting?<P ID="edit"><FONT SIZE=-1><EM>Edited by pIII_man on 03/24/03 05:49 PM.</EM></FONT></P>

btw I also have a pasive cooled processor (in one of my other computers)... An intel pentium II... HeHe. It has a gigantic heatsink, I think its copper... don't quite remember. Even that processor has a case fan blowing over the heatsink.

Thoroughbred B Athlon XP 1700+ overclocked to 1666mhz (equivalent of a 2000+) and undervolted from 1.6v to 1.575v. So its overclocked, undervolted,. and doesnt require a fan... Im very happy :smile:

hell with adequate case cooling you could probably passively cool a 2800 with an SLK-900 (same as SLK-800 but a bit bigger).


Long live ATI.

nah i doubt that, even with huge case flow

tombance what are your temps? this is an amazing feat indeed
what's the cfm of the side case fan?

Ive recently put the 12v casefan on 7v, so now its basically silent, and only moves a very small amount of air (not exactly sure of cfm). My temps are 37/45C idle/load. With the fan on 12v they were around 32/41C.

lol you mad, crazy fool... keep this up & you will undervalue all that coolermaster thermaltake & co are doing to make HSFs as LOUD AS POSSIBLE ;-)

Hmmm, wonder if I can get a valid page fault ???
these invalid ones are far too commonplace...

LOL, thats one of the main reasons why im doing this, sacrifising my temps to get rid of my 60mm POS whiner :smile:

Is this just an experiment or are you confident that your CPU is getting enough cooling long term?

definately get the slk900. big big surface areal, and lowering the voltage has a significant impact on temps.

Too be honest I don't recommend a full copper heatsink. Due to the very low airflow copper will be a very bad cooler (it tends to hold heat).

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on  

Nope, this is long term. Ive just lowered the PSU fan to 7v, now running even quiter (cant hear my PC over my typing). Temps are currently 32 MB / 36 CPU doing some light browsing.

I was thinking of this, but then decided it does a good enough job already, Im not going to bother spend that much money If I dont need to :-)

Are there any Aluminium HSF's that attach using the 4 holes on AMD mobos?

TechTV's, "Screensavers," featured Yoshi's Quiet PC (P4 based). Just 8 dBA (14 dba for frequencies below 100 Hz), tested in a listening room at Dolby Labs.

Pretty common stuff. Sound deadening material, quiet HSF, video heatpipe, soft-mounted, speed controlled, and oversized fans. Only slightly unusual things were the fan mufflers and the mod'd power supply.

The PC is kind of a commerical for Zalman (and I'm not a big fan of Zalman coolers) but I'd never seen the CNPS7000-Cu, a 109 mm orb-like cooler. It's massive and weighs in at 773 grams. The Zalman video heatpipe I had seen prevously.

Personally, I'd probably prefer something like the Spire Falconrock II/Speeze RaptorCool 1 which is a massive copper/aluminum hybrid. (I'm thinking about your idea, though).

The Swiftech MCX-462 is a copper baseplate/aluminium fins heatsink that uses them... so does the Alpha PAL8045 which is hybrid too.

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on  

Pretty good stuff, although I think to get that quiet I would need a new PSU. My current 350watter gets warm even when the comp is idle so requires a high CFM rating to be cooled effectively.

Well, Ive just managed to sell a P2 system for £100 so a New HSF may be what Im looking for. Then again, an nforce2 mobo would be nice in order to get those higher multipliers and more performance than my SiS745 mobo. Ahh, but i also need to replace my 5400RPM 20GB PIO hard disk.... So much to upgrade.

I think I really need to upgrade the HDD and mobo together (to save 2 formats/reinstalls), but that would cost a lot of money (about £180 probably). Maybe I should go for the HSF first, because that would only cost about £25, and I could also try and get a 120mm Casefan to replace my 80mm version (a little bit of modding required). hmmmm... I'll have to think about this.

Could be a problem.

I believe Yoshi mentioned that he controls the air flow having about 32 CFM thru the box. He must have his Stealth fans in the PSU running pretty slowly.
