775 fan socket dead?!

[dolb21]

Hi guys ! I have a problem with my CPU_fan socket as it does not delivers power to the fan!
I tried to put the fan on the system_2 socket ( on mobo) and it works, but not as i expected ( sometimes rans out of power ).

The CPU cooler has a 4 pin connector ( like the small power connector for floppy ).

Is it possible to "adapt" it to a molex ?

Again i must remind you that the cooler works, and the problem is only from the cpu_fan socket on the mobo.

Thanks !

Check your smartfan settings in the bios. Some boards are so sensitive that they shut off the fan for periods of time when the temps are within range of the settings.

Hi, in BIOS, in my PC health menu everything is set for disabled ( that means fans will run at full speed , so it should be running at full speed).

I forgot to mention, i recently assembled the PC ( as i moved and couldn't take all the system) so i didn't find the 4 pin CPU cable ( from the PSU ), and i forgot to plug it, of course it made a sparkle, and immediatly i switch off everything, and found the 4pin CPU cable and plug it in.

Now the system works normally, only that the CPU is on 65-70 degrees C all the time, and the fan is working at 650-760 rpm.

Any suggestions? Please.

Are those speeds from the bios or a hardware monitor program, such as speedfan?

Yes it's possible that it died either with age or by you shorting it out. You can use a Molex adapter and your fan will run at Full Speed. Alternatively you can buy a fan controller, either with an analog knob or digital control, to manually control your fan speed.

is the board a gigabyte motherboard?

 

[apache_lives]

should say if thats so then go into the bios, CTRL+F1 then hardware monitor? or health? section then change fan control type to PWM

The mobo is Gigabyte GA-EP41-UD3L , in PC health menu i cannot change fan control. I only can set-up alarms when is overheating.

Also, where can i find the 4pin to molex adaptor? I searched amazon but i found only 3pin to molex .

Cheers !
