Copper core CPU cooler for Intel 10th generation

[Shrek]

Replacement Intel CPU cooler finally got here; temperatures are about the same when stressing all cores

• Original Al heatsink 65°C
• New Al/Cu heatsink 66°C

but the fan does not ramp up and down so much and so is less annoying.

Not sure why the designed these coolers where the copper slug protrudes and is the only thing contacting the IHS plate. The all aluminum heat sinks, the entire base made contact with the IHS plate. AMD and Intel both do that. Energy storage increase while surface ares decreases.

The circular slug reaches to the edge of the IHS, so only the corners are left exposed.

Leaving available surface area.
However, one of my best water blocks is similar, leaving the 4 corners exposed. Which doesn't make a huge difference, but I prefer full coverages.

That is a good performance. Under full load and not cracking even close to 70C? You're solid. Call it good and forget about it until you need to blow/clean it out in a 6months.
