So there's these little holes in the cooling fin supports, and i though, "i wonder if i have some copper wire that'd fit that hole" I did, and here's what i've come up with: [attachment 7172 IMAG0218.jpg] I don't have a thermal camera, so have no idea how effective it is at cooling the top of the hot end. However, this, or something similar, might remove the need for the fan. (though i don't use a fan, so need, is perhaps too strong a word) The U shape helps keep the wire from vibrating out, as does the bend toward the bottom of the U. There's not a whole lot of surface area on the wire, but the idea is that the high thermal conductivity will spread out the heat and help pull it from the PEEK fins. I could always add longer wire pieces, too. https://reprap.org/forum/read.php?70,125223,125223#msg-125223 Sun, 10 May 2026 03:44:23 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?70,125223,125223#msg-125223 https://reprap.org/forum/read.php?70,125223,125223#msg-125223
