Need to be pretty careful with the voltage on the 0.13 micron AthlonXP's. I wouldn't go above 2.05v or so. Would create too much heat in a small area. You'd need one of the Thermalright heatsinks (or perhaps the Alpha 8045 or MC462). Thermalright SLK-800 would be best though. Should be available in perhaps a week or two. As I was saying about the heat output in a small area. The current Palomino core is 128mm². Thoroughbred core is 80mm². The AthlonXP (Palomino, 1.75v, 0.18um) 2100+ is 72 watts where as the AthlonXP (Thoroughbred, 1.65v, 0.13um) 2100+ is 67.9 watts. Now according to this everything looks fine.. just slap it in and it'll run cooler. Unfortunately not. Some of you may know where I am going with this.. This would mean the Palomino has a power dissipation of 0.5625 watts/mm². The Thoroughbred would be 0.84875 watts/mm². While it appears at first (due to a lower wattage) it'd run cooler in all actuality you'd need one heck of a copper heatsink. I'd like to see some sort of silver heat spreader put on those chips or perhaps even silver bottomed heatsinks however those would be rather expensive.. :) Best bet would be to make some small silver heat spreaders.. perhaps have them sealed to the core via Arctic Silver 3 & epoxy.. lap it totally flat. Should work great. Anyway, be careful if you overclock. Make sure you use silver based compound & remove ALL thermal pads from the heatsinks. It comes off best I've found w/ lighter fluid. Just make sure you wipe the heatsink down before installing it :) Also remember.. don't push the 0.13's more than 2.05v, the older 0.18's can do 2.2v easily though.
