This guide provides information on a variety of different metals' thermal conductivity and electrical conductivity. I did not take this FAQ, I did my own research on it. This guide is in the cooling sections for the fact that it shows thermal conductivity, and it is in off topic for the electrical conductivity. The electrical conductivity is measured in electron negativity in the Pauling scale, and the thermal conductivity is measured in W/(m·K)

Incase you want to look up a certain metal that list in alphabetical order will let you know about the metal.
Here are the lists in order of greatest conductivity.
Electrical Conductivity
Gold - 2.54
Lead - 2.33
Platinum - 2.28
Mercury - 2.00
Tin - 1.96
Silver - 1.93
Nickel - 1.91
Silicon - 1.90
Copper - 1.90
Cobalt - 1.88
Iron - 1.83
Zinc - 1.65
Aluminum - 1.61
Titanium - 1.54
Magnesium - 1.31
Thermal Conductivity
Silver - 429
Copper - 401
Gold - 317
Aluminum - 237
Magnesium - 156
Silicon - 149
Zinc - 116
Cobalt - 100
Nickel - 91
Iron - 80
Platinum - 72
Tin - 67
Lead - 35
Titanium - 22
Mercury - 9
Although diamonds are not on the list of thermal conductivity, I found it interesting to learn that they have a thermal conductivity of 900 - 2500. Manufactorers currently use synthetic diamonds or bort diamonds (low clarity bad coloring unfit for gem making) for cutting ect, they also use it to remove heat to keep other parts of the machinery from overheating, but as new advances in synthetic diamond manufactoring continue, we may see the day where heatsinks are made of diamond.

. I never knew diamond was so thermally conductive, I just had to mention it.
