Do I need more fans for my Corsair Carbide 330R Silent Edition?

[en_gender]

For intake, I have two Corsair ML120s. For exhaust, I have one Corsair ML120 in the back position and one of the Corsair 120mm case fans that were included with the 330R in the top position, where I've jacked up the top cover about a quarter inch.

Running NiceHash, my GTX 1060 6GB gets to about 56-59 degrees celsius running fans at around 77% and my i3-7100 gets to be about 48 degrees with my system temp at about 32. I think this is good, but I took the side cover off the case when running NiceHash, and the GPU temps dipped under 85—so it seems like I could improve the airflow somewhat.

However, my pressure calculations indicate that I have net negative pressure, which is not what I'm going for.
My pressure math is the following:
Intake: 2 x ML 120 (less 50% for filter and indirect intake) = 75
Exhaust: 1 x ML 120 (less 10% for mesh) + 1 x 120mm (less 40% for indirect exhaust) = 83.5
Delta: -8

I'm trying to accommodate these numbers by raising the fan curve on the intake and lowering it on the exhaust. Can anyone comment on whether adjusting the fan curves can compensate for a negative pressure delta?

Now, to fix the negative pressure, I could remove the 120mm fan that came with the case. Or, I could purchase two ML140s, and use them as intake fans and then . . . not use one of my ML120s? That doesn't really make sense.

Ultimately, my questions is, should I spend more time and money on getting this right? If not money, what adjustments should I make to achieve positive pressure?

I mean, it seems like I'm getting good temps under load. I feel like it could be better, but I hope someone can tell me if any gains would be marginal.

EDIT: Forgive me if this is in the wrong category. Mods, feel free to move it. Thanks!

The asnswer is just leave it and move on ... I messed around with fans for years. The only thing I recommend is to cut out the mesh at the back of the case (but never the mesh at the top) to allow the exhaust fans to work more efficiently. Removing the inlet filters just allows more dust in.

The ML fans are very good.

I got more fans. I purchased two ML140s for the front of the case and drilled a hole in the bottom for one of my ML120s. For exhaust, I have two ML120s at the top and one of the fans that came with the case in the rear. At load, the interior of the case reaches 30 degrees Celsius. So, pretty cool, I think. My GTX 1060 doesn't get above 60 degrees Celsius when benchmarking, with an 80%@55 degrees fan curve.
