Heatsinks don't necessarily absorb heat. They usually act to divert heat away from sensitive components, and the heat is dissipated by fans.
Any type of memory can be considered "tall" memory. This just relates to the physical dimensions of the memory module. So it is higher from the motherboard than similar memory modules. The main concern here is the heat sink for the CPU. When larger CPU heat sinks are used, they often cover the memory modules, so you would need memory that will fit under the heat sink. If there isn't enough clearance, then you cannot use both that heat sink and the tall memory modules.

heat sinks
All surfaces absorb some heat.
Heat - generated by your metabolism. The colour of your clothes is not important save that a black shirt will radiate heat from you more easily than a white one, but will absorb more external heat such as from the Sun.
They absorb light which is converted into heat energy
Flowers use their epicalyx and calyx to absorb sunlight.
A sponge definitely does have the ability to absorb heat. Sponges absorb heat as well as many other things like water.
no i don't thimg they absorb heat
If there was more heat to absorb than was already in the material.
A conductor does not absorb heat, it conducts heat so that the heat is evenly dispersed. It seems like it absorbs heat but it transfers heat to somewhere else.
If heat is generated during a chemical process, this indicates that it is an exothermic reaction.
