I am fairly new here and certainly haven't read every post on the forum (so might have missed some discussion of this), but I have seen several threads, particularly reviews, that seem like they might be missing a basic concept. I have seen many people gushing about "really great thermal capabilities" of a particular heat sink, host, or the combination thereof using statements like "It barely get's warm to the touch after being on almost a full minute" I just wanted to point out that if the host doesn't get warm to the touch it could be due to very poor thermal behavior. If you had a 100 deg.C diode surrounded by wood/plastic/fiberglass, you might easily say that it doesn't get warm to the touch. It seems that the best performance would come from a build that does get warm, as this means it is effectively absorbing heat from the diode, and will also be able to give that heat up to the air/your hand so it can be turned on again without too much wait. Admittedly, if it's a very large heatsink with the purpose of allowing a long transient "on" time before it must first be turned off, then it would also be cool to the touch for some time after a "cold start".
Does anyone have a sink/host they would describe as a great thermal performer, that they would also describe as getting warm quickly?
