PSU fan failure?

Hi,

 

Are there any safety switches in PSU that will prevent overheating during fan failure?

Unfortunately, it does not appear that SB-B700 has any kind safety switch to prevent overheating during fan failure. It does appear to come with a two-year warranty however. If yours is older than that, any failed components would need to be replaced, or bin it and purchase a new PSU.

Thank you for your response Doc.

 

One more question. There seems to be a system that controls fan speed depending on temperature. So there is a chance that the fan won't spin until there is high enough temperature. I just don't want to take a risk and wait to see if the fan will start to spin.

 

Do you have any suggestions how to test it?

Try using the computer on a hot day?

 

Note that if the CPU were to get too hot, it should cause the computer to shut down. (Mine do).

Yeah, i can try to test it like that, but like i've said - i'm afraid that it will overheat and cause some damage. CPU have safety switches but we're talking about PSU here.

Correct. I've had to replace the fan in a number of PSU's over the years. (Be careful when inside a PSU, they can bite).

You would be both better off and safer to simply replace the PSU, it is well out of warranty and unless you are a qualified electrician or technician you should not be opening up an electrical device that has the potential to cause serious injury or worse case scenario a fatality.

 

Please note that hardware such as PSUs will often have a label on them stating that there are no user serviceable parts, this basically means once faulty either get the item repaired by a professional or toss it in the trash, having the PSU repaired professionally would not be cost effective and replacing the unit with a good quality brand Bronze efficiency rated or above would be your best.option.
