Im using Afterburn to monitor the temp, workload % and fan %

I have tried several testings last night and these are the outcomes:-

Scenario 1 - Took out entire mobo and gpu and test without casing, air con room
GPU Temp 62 - 65 degree celcius

Scenario 2 - Assemble back the mobo into case, like the original state of the PC, air con room
GPU Temp 80 degree celcius peak

Scenario 3 - Open both side panels, air con room
GPU Temp 70 - 72 degree celcius

Scenario 4 - Open both side panels, no air con
GPU Temp 70 - 74 degree celcius

Scenario 5 - Install back both side panels, add 2 more fans at top panels for exhaust, no air con
GPU Temp 75 - 78 degree celcius

===============================================================

From the testings result, i think i can conclude the followings:-

1. The GPU factory setting makes the card to runs at full capacity with temperature limits at 80 degree celcius. (i set 83 degree in Afterburn)

2. The casing airflow is bad

3. live with in at scenario 5, until i have time to buy a new case and reassemble again
