Case Fan RPM

[Catch22]

I have the Razer edition H440 with two stock fans, running at 1200 RPM and two EK-Vardar F3-120 fans running at 1850 RPM and I was wondering if I should upgrade to all four fans to the EK Vardar F3-120's? For the rest of my specs that are relevant I have an A240G water cooling kit for my Cpu and Gpu. Cpu is a Ryzen 7 1700x oc to 3.9 Ghz and my Gpu is a GTX 1070 FE. 

 

TLDR How big of a difference would it make to upgrade two fans by 650 RPM in terms of temps?

 

Thanks for any help you can give!

I think it would depend on whether or not all your fans are being used on radiators. If you upgraded everything to EK Vardar, you would likely see a decrease in temperatures. RPMs aren't the only thing you want to measure fans by, there's also static pressure to take into account. Vardar fans are pretty much the best for watercooling(I could be wrong, feel free to correct me).

RPM probably wouldn't make that much of a difference in temps. If anything, get two more Vardars(i assume those are on your rad) and set the rad up in push/pull, you'll get significantly more airflow in the case to cool the rest of the components and you will see a significant drop in temp for the components that are cooled on the loop. Jayztwocents tested the temps for rads in push/pull and saw a pretty big temp drop when compared to just push or just pull. Make sure you have a good ratio of intake to exhaust, the two stock fans exhausting and the 4 vardars intaking should be a good combination, id suggest running the exhaust fans pretty slow just to be sure you have positive air pressure for less dust build up
