While I have not used Silver Arrow 130, it would be a good choice. I've used/tested most all Thermalright coolers until this year and all are amont the best in their class.
But case needs to flow more air than CPU and GPU use, so 1x 120mm fan on CPU needs more than 1x 120mm case intake fans. GPU with single fan (most have 2-3x 80/90mm fans) need than 1x 120 case intake fans. End result is 3x 120mm intakes will be about the minimum that can supply airflow demands of CPU & GPU .. and at least 3x 120mm exhaust vents. It this custom case going to be a tower? If so, can you use bottom intakes?
If case is not flowing more air than components use than components have to re-use their heated exhaust .. and every degree warmer the air into cooler is translates into same degrees hotter componet is. Below is link to basic guide to case airflow and how to optimize it:
