I have (what I believe to be) a fairly novel idea for cooling a PC, and I'm wondering if there's anyone out there with any thermo/fluid dynamics knowledge which I certainly don't have.
Would it be possible or feesable to move ALL case fans to a position say, 1 meter away, using strong SP fans connected through tubing to a microATX case?
I'm guessing that there will be significant drop off in performance proportional to the distance, the question is how much. Eg. 2x 200mm fans 1m away channeling air through 'tubing' to the front of the case vs 2x 120mm fans directly attached to the front intake?
The idea behind this being you could build a PC with hefty CPU & GPU heatsinks, and have a 'fan farm' in another room with equal if not higher cooling potential. I'd be interested to know if anyone's tried something similar or if there's a significant drop off in cooling performance.
1Any clue how this would transfer to a desktop-sized set-up? without any actual AC, how much air flow is really needed in a case? – Nick Booth – 2018-05-21T17:42:18.523
Your followup question is not possible to calculate with the information you provided. You would need to know the amount of volume of the case to determine how much airflow you needed. You won't get this with a couple fans, you would a significant amount of airflow, to keep a CPU cool enough to prevent it from overheating with 30 seconds of being turned on. You would still need a heatsink, and even my example cabinets, has a heatsink and their own fans to control the airflow. – Ramhound – 2018-05-21T17:45:02.227
