I changed my power sup, afther that when i try to play game my system restarts afther a few min.I thought it must be about cpu fan becasue normally it has to make more noise while in game. So i enter bios (its phoenix award) and disable "smart fan control" option than the fans run at full speed and i am able to play games without a problem, but it makes too much noise and i afraid of burrning fans motor. afther that i try to use "speedfan" but it is not able to control fan speed.

i controlled my fans cables and there are four cables connecting to mother from cpu fan.Beside them my hdd light is more active than before i change power suppley.

what should i do to run my fan normal? Do you have any idea? Thank you.

There may be an advanced section in BIOS/UEFI that ALSO controls fan speeds. The advanced section (if it exists) often lets one set the lower and upper fan RPM limits, and/or the temps at which fan RPMs increase/decrease, and/or manually set fan RPM to a fixed percentage of maximum RPM (e.g. 50% of 4000RPM = 2000RPM)

You can also try a freeware and Open Source program like Open Hardware Monitor which provides an somewhat less complicated (but less flexible/powerful) fan control interface than speedfan. Keep in mind that BIOS/UEFI settings may interfere with other fan control programs and you may have to experiment with those settings to let the programs (like speedfan, OHM, etc) gain fan RPM control.
