Do you have a fan controller? (Benifit: 4-6 temp gauges!)
Cooling is essentially a trial&error exercise.
But there are some basic (physics) laws.
The very first one is:
In an open case there is no airflow!!!!! Device temperature can only be achieved by direct airmovement to/from the component.
In a closed case:
Layout a basic cooling strategy BEFORE assembly. Where to locate components to benefit most from the air circulation that can be achieved (theoretically).
Then it is becomes a question of experimenting. Check temperatures at many components and places. Then start changing fan speeds and watch temps change (or not). Reversing air direction can also lead to some surprising results.
This is a very time consuming exercise, which remains tolerable if you approach it methodically.
That the PCI fan box doesn't do great things should be fairly obvious:
1. most of the opening area is blocked by sheet metal
2. the air needs to move around the corner.
Which in an open case results in zero benefit.
You would have to reverse your approach.
Your approach: remove as much warm air.
Better approach: supply as much fresh air to the graphics card(s), and use the rear fan box to help remove the air.
Hope that helps a bit.
It has 4 temp sensors but i havent used them. Dont know how to install them properly.
What do you mean by "direct airmovemet"? So an open case, means there's no need for fans, since the heat is going to be dissipated directly into the ambient.
BTW My True Black Supports 2 Fans, which i have alread installed. But which one is most important. Is it the one facing the rear part?
And a final question as to the cpus. Why is it that different cores have different temperatures and how are they affected? Core#2 always seems to run hotter, and core#3 is the coolest of them all. And this never changes.
They do? According to the specs these 230mm fans do 700 RPM/110 CFM/19 DBA.
Isnt this the fan of the 840?
