Im good at computers but can't understand why do they require these?

because processing information uses power and generates heat, this heat has to be removed from the chip else it will overheat. The early pentiums (I think) would go from ambient to >100C in about 1s if you removed the heat sink.

Sending electricity through a wire generates heat, unless you are making use of a superconductor (which we are not). Imagine billions of transistors with tiny little electric wires all working in unison to calculate all those fancy programs you run. They each contribute to heating up the chip ever so slightly, and in the end the heat needs to go somewhere or else it will just increase and melt down your motherboard and cause a fire. High heat conductive materials are then latched on the chips and then a fan dissipates the heat into the air in your room. This is an unfortunate side product of the current state of micro computing. Hopefully one day it will be negligible.

Many modern tablets do a good job at not getting hot without active cooling, but their processing power is many times lower than the best computers with the best graphics cards.

Graphics cards are a special kind of implementation of computing that lends itself towards parallelism. You can compute the second pixel's colour while the first one is also being computed by another part of the chip. Modern graphics cards have thousands of small specialized cores working all in parallel to calculate your frames at the same time to display the frames faster. This is why graphics cards are even more cooling hungry. Also, to push a card faster you can often increase the MHz of the card (frequency) which in turn creates more work to be possible inside the circuitry. Things happen faster but generate more and more heat. You can often easily overclock a graphics card to 10-20% higher out of the box without major problems but beyond that you need major upgrades of cooling such as more fans, larger and faster fans, or use water-blocks to take the heat straight out of the box at even more cost but with the ever diminishing return of investment, that puts a smile on millions of nerd faces every day. :)
