Need serious help with Corsair HX750

RejZoR · Dec 18, 2009

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.

disconnect the stock fan and then hook up your aftermarket fan to the motherboard or to a 4 pin connector...

You will fry that PSU without the stock fan... unless you get something equally as loud *and powerful* to replace it - ive fried an OCZ because i modded silent fans onto it.

Sell it and get a quieter PS. Zalman makes ones that are virtually silent.
