BEAMS Posted February 12, 2006 Is it normal for the cpu fan to shut off after 10 seconds of running when its connected directly to the boards cpu fan connection. I sure dont think it is but someone told me that it could be normal and just to watch the heatsink and feel if it gets hot and i will know if its working by seeing the fan start up when the heatsink gets warm. I have my cpu fan running off the ps through an adapter. Quote Share this post Link to post Share on other sites

EdLSmith Posted February 12, 2006 Use of fan headers on board are not reccommended. Bad for board. Yes the setting for this is in BIOs. Fan turn on at 25C and spin full RPM where you adjust for. It is not uncommon for HS with heatpipes to do this. Keep a close monitor of temps. Quote Share this post Link to post Share on other sites
BEAMS Posted February 12, 2006 Ok thanks, i noticed my cpu was running at 20c in bios on start up so that make sense. Sorry for the stupid question, im just used to my old asus boards and they never did that. Quote Share this post Link to post Share on other sites
wevsspot Posted February 12, 2006 No question is ever stupid unless it isn't asked. Yes, the fan behavior you describe is normal. I'd follow the previous recommendation about pulling all fans off of m/b headers. I use a fan controller from PCToys and it works great. The only fan I have on a m/b header is the chipset fan.
