Power supply and motherboard fans

My neighbor told me she heard a loud noise from a fan in the back of the machine and after this her computer started to reboot itself after about hour of use. When I checked it , I found that the fan in the p.s., and on the motherboard (an Asus A7V133) were not running. I suppose the sound was from the p.s. fan, but i'm not too sure about the fan on the motherboard. Is it possible the change the fan in the p.s., or it is easier to just buy a new one? Can the fan on the motherboard be easily changed?

 

They are both relatively easy to change if you have good mechanical skills. Often the power supply case is riveted to the chassis, so you will need the proper tools to drill out or grind the heads off.

Under certain circumstances, I have simply cut the grill slots away to allow access to the PS fan and managed to remove it by breaking it into pieces without having to pull the PS from the chassis. Then I mount a new fan on the outside of the cabinet over the PS hole. The fan electrical leads can be reconnected to the old ones and dressed out of the way. That's just a field expedient method for older limited value boxes though. Let your conscience be your guide.

As for the Processor fan, it will normally just snap off but inspect to verify that. It may be sc rewed in place.

I would be concerned about the PS proper if both fans failed at the same time. I suppose that didn't happen and that it may have been operating with only one fan for some time. That sounds like it may be about over the hill anyway.

Good luck.

Hi,

JUst my 2 cents here but for trouble it is worth I would just change the PSU and be done with it. Consider how old is the PSU and how much Wattage, you can get a bit more wattage on a new one and it gives you a bit of room to play later if your friend/nighbor so desires to add drives or what not later.

Probably quicker to change to a new one as well. Surferdude is correct though in a pinch if you had to drill or in some way remove the fan from the PSU you could. I think you would be happier with a new one and a warranty!!!!

Cpu fan should either unscrew or unclip, but my guess is that if the PSU went out that might be the cause of the Cpu fan going out, never the less you can pick a cpu fan real cheap as well

Good Luck.
