Ok, I'm kind of up to speed on how the axial flow fans vs blower fans differ on graphics cards, and where they are best/most effective.
Granted - blower type cards are better suite for small cases with poor airflow so that the rest of the components don't have additional hot air to deal with, and are better suited in SLI config.
Granted - axial type fans cool better in larger cases with good airflow (possibly because they're larger and can have 2 or 3 on a card) and are quieter.
End of the day, the axial flow type cooler does leave its exhaust air inside the case, leaving it up to the case fans to exhaust the hot air from GPU in addition to that from the CPU and rest of motherboard heat sources, which in all likelihood raises the CPU temperature.
Blower type fans will take some of the fresh air and exhaust it out of the case - they may not dump the hot air from GPU back inside the case, but I suppose that does reduce the net amount of air remaining to cool the CPU.
I'm particularly seeking the experiences from folks who have used both reference (blower type) and custom (axial flow) type cooler fans in larger mid and full tower cases , the same GPU chip , if there is any measurable, consistent difference in CPU temperature.
I have an Antec 1100 v2 that's fairly large and airy : 2x 120mm intake fans, 1x120mm rear exhaust , 2x 120mm top exhaust fans, and has room for 5-6 more 120mm fans. I plan to put 2x 120mm fans at the side window to blow air in at the GPU/motherboard when I get my GPU.
I'm more concerned about temps than noise though, being in the tropics, but haven't used any blower type cards before , hence willing to hedge on blower type if there's at least 4-5ºC difference consistently in CPU temperature at load.
The question is - which type will leave me with a cooler CPU (assuming the blower type GPU cooler, even if hotter, is within manufacturer specified limit) ? I gather some blowers are poor and some are excellent, same with axial fans, I'm looking at getting RX480/GTX1070/GTX1080 , depending on pricing and availability here.
