Twin Frozr IV

[pbenologa]

Anyone knows how heat is dissipated in a Twin Frozr IV?

Isn't it pretty straightforward like most dual fan gpu coolers?

The heat is drawn away from the gpu by a heatsink and heatpipes. The heatsink is then cooled by the fans that push air through the fins. The air then escapes out the sides of the graphics card to be exhausted by the case. Some of the heat escapes out the back of the graphics card through small vents.

As for the vrms, they transfer heat to plates that are actively and passively cooled by case airflow and air from the 2 fans.

So heat is dissipated like this? 

          _______________

80% of the hot air is released at the back then 20% at the front?

[Kaiser Soze]

So you want a specific percentage?

 

I think it also depends on the card ( how sealed it is from the sides) and on the case airflow in general (negative-positive)

No. Very little of the heat is actually exhausted out of the back. It mostly comes out of the sides.

Oh! So all i can do is to optimize airflow so that the dissipated heat on the sides will go out of the case?

Pretty much.

After reading from this http://www.silverstonetek.com/techtalk_cont.php?tid=wh_positive&area=en, Is it better to have positive airflow to push away the hot air inside the case?

Positive airflow has little to do with getting heat out of your case. It has to do with pushing air outside through the cracks of the case where there aren't fans instead of sucking in air including anything that may be in it like dust through the cracks with negative airflow.

So neither type of airflow has no impact on getting the heat out of the case? Any ideas on how to push the heat efficiently and faster out of the case?

It's not that they don't have any impact. It's just that positive airflow is generally preferred for keeping dust out more than anything else. 

Better fans will generally help. As for fan placement, it depends on the case and the components.
