My suspicion is that either your tobacco is too dry, or you are puffing too fast.
Corn Cobb pipes are notorious for being "cool smoking" because they just do not have the heat retaining density of briar.
Regardless of material, if the pipe is too hot to handle. It is a sign that it is being smoked too fast. Much like "hotboxing" a cigarette.
Pipe smoking "should" be relaxing (although I admit it can be, at times, infuriating). A common saying is that the tobacco should be on the verge of going out between puffs. The payoff for this is that once achieved, you will discover that the smoke itself takes on a whole new level of flavor and aroma.
Are you a transitional smoker? Meaning are you going from cigarettes to pipe? I only ask because cigs aren't generally regarded as something to "enjoy" by smokers. they are regarded more often as a delivery method.
