heat spreaders really work or just look cool?

so that's the question do they actually spread out more heat than a card that doesn't?

  1. They do really work. The thing is if they're on something that normally doesn't heat up much, like DRAM, the amount of heat they're spreading is negligible, making them cool-looking but unnecessary features.

    Yes they do dispense heat as mentioned above, but most DRAM doesn't really get all that hot, the sinks came about with DDR2 that often ran at (comparatively) much higher voltages (often 2.1 and up) and during a period the when you OCed you were often OCing everything (socket 775, OCing through the FSB). The appeal of the 'looks' has carried over into DDR3 that runs lower 1.5 and below and in the area of 1.6-1.65 for high performance (as well as just plain weak i.e. 1333/1600 sticks with med/high CLs) sticks
  3. so a DDR 3 stick on 1600 just looks good with the heat spreaders if i got what you said?

    Yes, that's pretty much it. They look cool.
  5. Look cool yes, but also help spread heat into the air to keep it off the mobo, same as a CPU cooler or heat shields on the caps and all - in short an effort to keep the mobo as cool as possible
