New CPU Fan makes noise on startup and out of sleep mode. Tags: CPUs Sleep Mode Fan Last response: February 5, 2013 5:09 PM in CPUs Share justmark81 February 5, 2013 4:56:17 PM Hello, My new CPU fan makes noise when it starts up (2 seconds of full speed fan ) and after waking out of sleep mode. Why is that? Did i do something wrong? More about : cpu fan makes noise startup sleep mode eightdrunkengods February 5, 2013 5:06:44 PM It doesn't sound horrible or anything? It just spins up fast for a few seconds? Does everything run fine otherwise? We have some Lenovos at work that have always done that. I don't think it's a problem. justmark81 February 5, 2013 5:09:55 PM Yes it works great, low temperatures.. my old CPU+Fan never started this way, so i wasnt sure it was normal. Thanks alot!
