Second followup to the airflow mod
I had two burning questions in my head:
- What happens if the fan is pointing down?
- Are the intake fans creating much of a difference?
The new configs are:
- Intake at 30% with the other fans at a custom fan curve
- Fan pointing down, not running CAM
- Fan pointing down, running with CAM at 50% fans
So here's all the data compiled. Regarding the charts, instead of using maximum clock speed (which all of them were within 1% of each other), I used maximum temperature instead which is a far more useful statistic. I also found a better way to represent the performance cap data. Instead of showing bars and counts, the counts are normalized to 100% and all of the performance cap reasons take a chunk of this. This makes it much easier to visualize how often the GPU spent in that reason.
Spoiler alert: Running with the fan pointing down without CAM running performed the worst, even running into Thermal performance caps. However, using CAM to turn the fans on to 50% seemed to help a lot. The 30% intake fans performed very well. Which makes me wonder if this is just a problem with air circulation within the case rather than a problem of trying to push air in.
Why bother with gathering this data?
One could think that this affects just my configuration, but I think it affects any micro-ATX case with a tempered glass side panel and a PSU shroud. If anything, the results from this data gathering could be generalized for other people who want to tweak with getting the best cooling performance.
