I want to change the fan with something more silent than factory thingie. But i have one major problem. How to know which fan will be good for it? Can someone do a big favor for me and measure a starting voltage for the fan or hat are the characteristics of the original fan (voltages, RPM etc) I've used Xigmatek XLF-1455 fan but it just won't rotate. It just keeps on restarting and never starts to fully spin.
