How much heat does RAM generate?

Enough to warrant the use of a fan near/over them? How good do the heatspreaders work for them, or should I even bother? No, my system isn't overheating...just curious.

i doubt they give off too much heat. i'm not an expert in any way about ram but i'm sure you can go a lot farther with heatspreaders than you can without

I don't know really, but my ram can get pretty darn hot after loading the system for a little bit. After idling all day its not cool to the touch. I'm guessing it runs hotter than my CPU but I don't have any temp probe to find out.

Mine have always gotten hot enough to feel really hot. Leave your fingers on there for a bit and they feel like they could burn me. (never overclocked or anything either). With my system ram and all the ram on my I-ram drive my system is putting out some good heat.

I dont think you need heat spreaders though. It almost seems like they just keep the heat in and retain more of the heat.

rambus and fb-dimms generate ALOT of heat.

DDR1 generates a bit
and DDR2 generates even less.
