PII fan?

Curiosity (well, mainly) question: Everything I read says without a heatsink and an embedded fan, the processor chip can burn up in less than a minute. Is this referring to just the latest (well, say PIII, maybe, and beyond) CPUs. I seem to recall PII-233MHz with a fair-sized heatsink, but NO fan. Can anyone verify this?

Thanks.
 
Typically you need both a heatsink and fan (at least since the days of the original Pentium). However, I have seen some systems where they've had larger heatsinks and no fan (on certain Compaq models) and not had a problem. Also, today there is a wide array of high performance heatsinks that we didn't have 4-5 years ago in the days of the Pentium II. I would think that with a sufficiently large heatsink on the CPU you would be OK, especially if the heatsink were directly in the path of one of the system fans.
 
kmcferrin,

Thanks for the helpful cogent info.

Historically fans were introduced in the early PII MMX days, from about PII 233 onwards although many early Celerons didn't have a fan until they reached over the 333mhz mark.
At that time some manufactures chose passive, others fitted a fan, from 350mhz practically everything had a fan.

There were exceptions depending on manufacturer.

Obviously from that point there was just too much heat for a passive to manage.

I have a Dell (customer through it out), that has a P4. Large passive heatsink, covered by a plastic chute ending at a fan mounted on the case. Big, ugly, but works!

Typical Dell layout, but hardly passive if a fan with couling is directing air onto it. lol.[2thumbsup]
I guess that depends on interpretation.

rwbrick,
I didn't start seeing fans until around the AMD K-5 and Cyrix 133. The PII was the first that I saw with just a heatsink (the size of a brick) since the Pentium 75.

I think the first PII I saw with a fan was the 266.
I think the celeron 300A was the one we use to fan and over clock as well.

It has been a long time and I may be wrong about some/all of this so don't take me as fact.
