1. Front fans....look at the rpm.....get the one that's slower....think noise.
3. Google 3pin vs 4pin fan.....has to do with pwm
Have you thought about testing this with just the stock fans.
I plan on buying these two for my build:
Case: Thermaltake Level 20 XT
Motherboard: Asus ROG Zenith Extreme
The case supports multiple fans, and that's where my questions begin:
1.- I can put either in the front, 3x 120mm or 2x 200mm fans, which of those two options would be better if both provide 75 CFM per fan?
2.- How many fan connectors (or however that's called) does that motherboars has?
3.- What's the difference between a 3 Pin and a 3/4 Pin power connector?
4.- If my motherboard, say, has two fan power connectors but I plan on buying 6+ fans, what do I do?
Thank you very much in advance! ![]()
