Passive-cooling on a Tualatin Celeron 1.3?

[MercenaryForHire]

What would handle this? The Zalman CNPS3000+ looks up to the task, and at only 148g it's not about to break a clip.
Any other suggestions?

Edit - The Zalman won't fit without clipping or bending fins. Think I can get away with that?

Whats it in? I had a 1.0a in a sv25 shuttle box that was passively cooled using an alpha pep66.

I kind of doubt that would work. I had a 1.1A with an SLK800 on it that still needed an L1A Panaflo running at 7 volts ot cool it enough. At 5V it idled in the low 40°C range and that was during the winter, Prime95 load was in the high 50°C range. I suppose you might be able to run w/o a fan but it would be running awful hot. An L1A at 7V is basically inaudible when it's inside the case and will certainly run much cooler than w/o any fan on it. I'd try something like that.

Should have mentioned that before. IBM Netvista A20i. The PSU is directly over the CPU socket ... apparently the Zalman would just squeeze in there and get air pulled directly off it with the PSU's 92mm fan. Pretty much a zero-clearance situation here. There's about 70mm space, and the Zalman is 65mm.

Mingon - I'll check into that. That's the sort of thing I'm looking for - things that weren't meant to passive-cool but work just fine under circumstances.

RalfHutter - Always an option there. I may go with a 5Ved 80mm, but I'd have to have it pulling off the sink so as not to directly fight the PSU fan.

<pet peeve>slapping a fan on a heat sink doesn't make it active cooling</pet peeve>

i bet my swiftech could do it without the fan on the heat sink. anyway, if you make a duct of out that coke bottle that you made your rum and coke with you can pull all the air that the fan moves through the CPU heat sink. undervolt the cpu and you'll be fine doing that.

Those fuggers run hot IMO, you'd be better off with an original P3 at about 866mhz. Way more surface area and no heat spreader to raise temps.

I'm using Thermalright SK-6+ heatsinks in my P3-S 1.4 GHz dualie. One time, after installing some quieter fans, I ran the system for about 3 days before I realized that the fans were not plugged in. During that time the system was subjected to downright abusive levels of GCC with Quake 3 in between. No noticable degredation in stability, although those heatsinks got pretty hot.

By "Swiftech" do you mean the MC(X)462 series? You know, the ones that secure with four bolts and weigh upwards of two pounds and cost around $40? Considering the Zalman is only CDN$30, I'm leaning towards that.

I was considering the Ghetto Ducting mod previously. If you can suggest a smaller/lighter/cheaper heatsink, that might be the WinnAr.

They both cost about the same, but the 1.3 will crush the 866. And weak isn't what I'm going for here.

Firstly - Dual P3-S 1.4s = :heart:

Sounds interesting, but how was the airflow around the rest of the system? Was there any other source of forced air or exhaust near the CPUs? Or any other fans in the system at all?

Update - After some further dimensional and airflow analysis, I'm going with the Zalman. Wish me luck.
