Need a new fan to Cool HDD bay

[joe159540]

Probably is its a stock one and the Pc is refurbished so its probably extremely old and worn

It procides power but only when the mobo/CPU is as a cetain temp.

If I remember correctly, black is ground, red is +12v, and the yellow is RPM report. The fan doesn't actually get any data from the motherboard, only sending to the motheboard what it's current speed is. If the motherboard is turning power on and off to this connector, then it may be a motherboard problem (either physical problem or a settings problem in the BIOS) and not a fan problem.

I disagree I believe the fan can be bad and they do ware out.

Fans wear out all the time, absolutely. However, that is not what I was what I was implying. Joe says

This makes it sound like the fan is not running AT ALL unless the the system temperature reaches a certain temperature. My post afterwards was addressing how the motherboard cannot actively control that fan unless it's turning that connector on and off. If the fan is not receiving any power unless under certain conditions, that sounds more lile a problem with the motherboard, not the fan.

What I did not mention or address however, is that at lower RPMs (if the fan infact is temperature controlled with a diode for instance) the fan could be partially seized up due to wear and tear, and only when the fan attempts to run at higher RPMs is when it finally turns over. That could appear to be that the fan is only selectively getting power. To test this, Joe could try and give the fan a jumpstart when at idle. That is to say, if the fan is not moving, Joe could give the impeller a little spin and see if the fan continues on it's own. If it immediately stops, then there's a chance that the fan is not getting power. If it goes on it's own or chugs down to a stop, the motor is seizing.

Either way, if the fan is as old as Joe suspects, it definitely would not hurt to replace it.

I Will be replacing it with a 82mm fan at the front and back
Thank you to everyone for all their time and help
