Globalwin FOP32 (slower fan) and VOS32. Alpha P3125 and PAL6035. I also bought 2x Tennmax Lasagna (gpu heatsink) and a P3STF.

I still have a Lasagna, the P3125 and PAL6035. PAL6035 fits where larger Socket A heatsinks won't.

Globalwin FOP38 or something wasn't it? Damn loud bugger.... I have a couple of Cooler Master s370 heatsinks also, one that's pretty tall but slim with a 4000rpm fan and another short little bugger with a real Napoleon complex- something like a 6000rpm fan- sounds like an electric drill. Couldn't stand it for any amount of time.

FOP32 and FOP38 - very loud and nothing but average cooling. Still, it was a better choice then most other things you could buy at the time. the 32 would keep it cooled at default, and 38 could even cool it when somewhat overclocked.

Yeah I think the solid aluminum design if the FOP3x and VOS32 heatsinks was limiting. Thermaltake Orbs were all aluminum and overrated too.

Alpha had the inset copper, fancy hexagonal pins, black anodizing and the shroud to guide airflow. It all added up to a bit more heat transfer efficiency apparently .

I'm resurrecting this thread because I've done what I suggested those years ago. Pentium II SECC OEM heatsink that was normally fan-less now attached to an Athlon. The Athlon had the usual 5000 RPM 60mm fan equipped cooler that was very noisy. Now it's almost silent.

Athlon before and after. Undervolted fan attached with zip ties. These OEM heatsinks attach with screws. The Athlon screw holes were untapped but steel screws don't have much trouble tapping aluminum.

Wow, I have one of those exact coolers on an old PII 266 and I was just looking at it today and thinking "Man, that's a beefy cooler for such a slow CPU."

Using a Goldenorb with a copper spacer could save Coppermine's 😁

I love seeing all these Orion 1GHz Athlons still up and running. I'd love a golden orb for mine, but swaaye has the right idea. Those giant passive SECC heatsinks with a 80mm or larger fan attached are plentiful, cheap, and effective. Are you monitoring temperatures on that setup? If so, what are you seeing at idle and load?

Apparently the ASUS K7V needs an external thermistor connected to read CPU temp. And that would just tell you the temp of that area of the heatsink (with unknown accuracy at that). Not very useful.

I've put my finger on the heatsink during some Prime95 and it's quite warm but it isn't burning hot. It seems to be conducting the heat well. The fan seems to move air through it well enough too.

I love these SECC modules and I wish they'd bring them back for modern architectures.

What about the beefy Montac Arctic Circle, a.k.a Panaflo "Orb" ? I still have mine. It's pretty hefty as it's one solid cut piece of aluminum. These were re-purposed HP coolers that were re-milled to attach to Athlon K7s.
