Howdy all, I recently upgraded many of the components in my old system to bring some life into an out dated PC. In doing so one of the things I added was a Corsair H50 cooler. When I first got the cooler it made a trickling sound and I had no fan recognition issues. Now when I start the system it says there is a cpu fan error and it shuts off and there is no longer a trickling noise which could be air working it's way out of the lines somewhere. If I sit there and start it many times sometimes it turns on and once on is stable. I checked the temps of the cpu both while playing games and just surfing and they seem to sit in a safe range (30-47) only a few times reaching the 50's. I am not sure if the fan is bad but the temps staying where they do indicates other issues to me. Does anyone have any ideas? Is the cooler bad, and if not how do I get the system to recognize the fan? My final question is I have swapped the radiator fan to the cpu slot and the pump to the case fan slot, I did this in hopes of tricking the mobo, but wanted to know if it was safe to do this before running it in this configuration for any amount of time.
