I arranged the case and rad fans in what I think is unconventional. Compared to my corsair case, the Lian Li case just seems difficult to keep the aesthetics and practical case cooling.
I'm not giving up.
I decided to try both rads exhaust and the case fans intake.
I do have a slight negative pressure. I installed filters at the air flow entries for now.
I notice I was getting higher air temps at the bottom rad compared to the top rad. At first I thought it was pulling the hot exhaust air back into the case from the PSU.
I blocked the PCI from air entering the case and the temps climbed another degree. To the right of the bottom rad was another airway. I blocked that and it climbed even higher again.
I was running Aida Stress test on the GPU and CPU and the temps were steady. I think the CPU approached 90c and the GPU at 40c after half hour or so.
Then I thought, what if I slowed the bottom raid push/pull down and see how it affects the temps.
The top airflow temps increase and the bottom airflow temp decrease. I felt dumb.
I admit I been so focused on radiators and water cooling, I never thought about case airflow balancing. I also wouldn't believe just adjusting fan rpm's that you can watch temps in the case change that fast.
Even at idle I can see a difference in temps. The bottoms rads was just exhausting more air then the top and allowed the top to get the cooler air from the back.
In the end, I don't think it matters much since the water loop is balanced. The air flowing through that RAD did hit 31 deg during the stress test at 100% RPM.
Attached are screenshots at idle. 100% RPM and 50% RPM.
Current test arrangement below.....
- I placed couple artic 140mm P14 and Noctua 92mm for intake on the flipside.
- I put spacers behind the distro plate and removed grommets in a few key areas where the rear fans are.
Installed temp sensors located...
- Flipside between the intake fans.
- left fan of top rad
- right fan of top rad
- center of bottom rad.
