Old INTEL CPU Coolers

[Ciuwas]

I just noticed that the old Intel heatsink s didn't even have copper slugs. Is this model specific or are all of them like this?

It's model specific. My i3-4170 has no copper center, but the Pentium G3258 has one.

Is that just missing the slug? The old heat sinks did in fact have slugs (put one on my bro's 7700), that specific CPU cooler pictured would not work as a heat sink because it doesn't have a way to contact the CPU

The opposite side almost certainly has a flat on it. If I can find the one that came boxed with my 4790k, I'll post it up. It was set up the same way.

Oh I see, so the slug is smaller than I thought. Still, it's there, and conducts heat better.

The "cup" part of the slug sits just beneath the dead zone of the fan

Now I remember, I have seen it before, it's round on the inside. The picture in the OP reminds me of the Wraith spire with the vapor chamber removed.

More or less, yeah. It seems as though the slug is just friction fit as well, given enough pressure, I'm confident I could pop her right out of there. I can't imagine a vapor chamber in that small of a space would have any meaningful impact.

I've had to use this thing interim after I had an AIO fail and before all the parts for my current loop arrived to keep my system up. It was remarkably inefficient at cooling. It surprises me that Intel would even package this thing up with a 4790k. Stock clocks and voltages, Idle temps were in the low 60's (ambient of ~10-15c), and a couple of times I hit thermal shutdown under what I'd consider to be relatively moderate load. Undervolting and cleaning up the flat surface of the slug (even with light lapping and polishing, it's not perfectly smooth) brought temps down to functional, but it was far more work than it was worth.

I think it's weird that Intel would just do this for some small amount of coolers. Mine was from an i5 - 4950.

It's likely a "this was cheap at the time so we're doing this" type of thing. Extruding is about as cheap as manufacturing gets, and if it doesn't need the slug, why bother?
I wouldn't trust running a stock cooler with or without a copper insert on anything important anyway.

My R5 1600 wraith spire has a copper bottom, it is missing in 2600.
