Skipping a few steps ahead I’m showing you the TJ09 with a system installed, I’ve marked the airflow inside the case with RED arrows for hot air removal, and BLUE arrows for cool air incoming:
As you can see the cooling potential of the TJ09 is quite good, fully decked out the case pressure inside the motherboard area will be negative as more air is being removed and blown inside. The hard drive area however has low active airflow as the 120mm has not a lot of room to work in.
The most unordinary of the TJ09 is without a doubt the middle fan:
This fan is rated at 1200rpm and pulls cool air in through the two openings at each side and blows towards the VGA area. The metal grill serves as a finger guard/dust filter and prevents small objects from being sucked in and cause havoc. Although with a low CFM fan like the one used here airflow around the area is not extremely strong.
Moving to the top of the case you find two 120mm fan holders, the fans click into place without the need for tools:
These fan holders can be removed to make room for other hardware… like a radiator? If we take a look at the backside of the case near the top, we’ll see further ventilation holes which help to passively remove the heat collected there:
The removable motherboard panel reveals further cooling powers as well as the pre-installed water cooling ready features:
The 120mm fan has a fan guard and is also rated at 1200rpm, the small black dots you see at the left/top side can be removed to reveals precut holes for water cooling tubes.
