Thread: Antec 900 fans stopped working?

I built my first PC from scratch, and even managed to put everything into my Antec 900 case, and all was fine for months. But after I have left it at the service for some (memory) problem, I saw that the 200 mm and the upper 120 mm fan are not working. I realized this when I tried to play games on it, and the sound of the front bottom fan (the only one of the 2 front and 1 upper fans that is working at the moment) became louder and louder with every second, and I got scared to burn up something and rebooted and cannot play many of my games.

What could be the cause of the single fan "speeding up"? Should/can I put the other fans into action? How? What could be wrong? Any cables I have to reconnect/check?

Help please! I'm quite novice in the cables of the pc ?

You need to go through and recheck all of your wiring. It sounds like something has come unplugged as far as the fans that aren't running now. What kind of power supply did you installed on your pc.

If you used a low grade psu that could single handedly be the problem for the speed up issue.

Give a total list of your components as well. Someone may recognize the motherboard and went through the same issue.

Thanks a lot. You were right - the cables were disconnected now it's ok, but the real problem which pointed me to check the fans was actually - when I start some of my games, a fan (I couldn't find out which, but I think it is NOT the front or upper fans, but either the cpu or back fan) speeds up and gets louder and louder (just like the revving up of fighter planes) and I get scared and quit the game. What could be the cause for this and how could I solve it?

You should leave your fans as they are, when you start a game your CPU will be under load and the fan will kick in just to keep it nice and cool.

If you really want to stop it, then you'll have to change it in your bios, but I would leave it just to keep your components cool.

Oh! So there is no problem! Good to know that however, I'm not so sure, but I seem to remember that it was much quieter when I played games last year (I had a pause of 14 months or so when I didn't touch any game, due to business). That's actually also the reason why I realized the noise this time (because in the past there was none).

I'm using the default settings of my bios, by the way.
