When you say custom blower do you mean axially cooled GPUs with typically multiple fans?
Reference blower, or squirrel cage fans, intake air from the case and exhaust it. They can reduce overall temperature of the system.
Typical custom cooling solutions have fans that pull air in and up through the radiator on the GPU and out through the sides/front, and to some extent, out the rear of the card. These cool the GPU, but the heat is exchanged inside the case. That heat needs to be exhausted and fresh air brought in by other fans.
In most contemporary cases the rear exhaust fan should stay as such. Since the power supply is often bottom mounted and has its own airflow the rear exhaust is the only exhaust in cheaper cases.
For dust reduction you do typically want more intake than exhaust, so that air isn't being pulled in through small gaps.

Custom graphics card fan setups will be fan type or liquid cooling.
Stock fans may be blower types.
A blower cooler takes in air from the case and directs the exhaust directly out the back of the card and the case.
A fan type arrangement also takes in air from inside of the case, but the heated air is released mostly within the case, depending on case cooling to ultimately get rid of the heat.
Such fans look impressive in reviews which are done in an open test bed.
In a case, they depend on case cooling.
What is good case cooling??
It is best to concentrate on getting sufficient fresh cooling air INTO the case.
Whatever comes in will exit somewhere, taking heat from your parts with it.
To my mind, if you have two 120mm/140mm front intake fans, you will have sufficient intake air to cool a overclocked cpu and a strong graphics card.
If all the front intake air is filtered, your parts will stay cleaner.
As a caveat... Do not use strong exhaust fans or it will draw in unfiltered air from adjacent openings.
Liquid cooling complicates matters.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu or gpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cooling will be less effective because it uses pre heated case air.
