Jstrat31 Posted December 3, 2013 Share Posted December 3, 2013 I juts purchased a H55, if I plug the pump into the pWR_fan header it's quite but shows as only running at 1500rmp. Is this a normal speed?? If I attached it to a molex to fan adapter it makes the worts grinding noise I've ever heard. Same if I put if in any other fan header with the fan control setting turned off. The pump should be able to run max all the time Without issue. Do I have a defective unit??
