EiSkip Posted December 19, 2015 Share Posted December 19, 2015 Howdy all! For Christmas, i wanted to buy my PC an overkill upgrade, because overkill is nice. I had previously a Corsair GS700 PSU that was a bit noisy, but a utmost pain in the bum for being non-modular. After a couple hours of shopping, i decided to get the RM1000x (silent, no corsair link but who cares, overall good reviews, good 80 plus gold AND MODULAR :D: ) Hooking it up was easier than removing the GS700. But once all was plugged in and running, i noticed that my fan controller would not power the case fans anymore (3 noctua industrial 140mm PWM and 4 noctua industrial 120mm PWM. Don't tell me that it's too many fans, i know and i love overkill!) My fan controller is a lamptron FAN-ATIC http://www.lamptron.com/product/controllers/fan-atic-5-port/ I chose this one for the switchy looks and the easy settings (OFF, 5v, 12v). That way i could easily turn down the noise while idling, then play between low and high setting depending the gaming load. With the Old GS700, the case fans would start on both, depending on the switch position (off, 5v, 12) With the new RMX1000, the fans twitch on startup if the switches are on the 5v setting (the controller LEDS are on, and i can start fans with a flick of the finger, after which they'll continue to spin on their normal low speed until i put the controller switch to OFF. The only non-manual way to start the fans i found so far is to trottle them to full power (pushing the switch to 12v them setting it back to 5v) After noticing the problem, i unpluged the RMX and pluged back the GS700 to see if it was the Fan controller who died. Everything started perfectly, proving that it was a problem with the new RMX PSU and not the the Fan controller TLDR: I can't make the case fans start on low speed (5v), i absolutely need to trottle them to get them spinning. How can we fix this? Side question: Does undervolting fans could cause premature usure and cause them to die early? Link to comment Share on other sites More sharing options...
