"Urgent help" fan Problem

[clippingpathlab]

Today while working through my computer it shut down suddenly and every time i tried to power on the CPU it restarted than i found that the cooling fan of my power supply is off. it doesn't run. what should i do now? please help me

Sounds like a faulty power supply.

Can you try another one?

the fan was likely dead for a long time, and now something int the PS has overheated to the point of failure

Buy a new PSU. You always have to have a backup PSU at hand.

I guess by "urgent help" he meant not really urgent, hence the quotation marks. No reply back since posting this on 7/28.

It is normal to happen after long usage PSU can fail.
Replace it with new one. Buy some quality PSU like Chieftec maybe it is not cheap, but it will last long.

Will the PSU work ok after being off for a while? Maybe it has a thermal shut down feature. If it still runs fine I'd just replace the fan. Though it could be that it failed from overheating. Probably blew mosfets or something.

On a lot of newer power supply's the fan will only run when it needs to. I hardly ever see the fan run on my corsair hx series power supply's.
Just a thought.... Not saying there's not something wrong. You ought to check your psu manual and see if the fan is supposed to be running always or not.

Yea... most good power supplies today not only use a variable speed fan, but run with no fan during cold starts and no load. If you put your hand on the psu and don't find it dangerously warm, it isn't the psu temp.

are you sure that its your PSU?
I bought a faulty GPU which didn't let the system to boot up I mean no power at all, replaced it and everything started working fine.

I had a cheap PSU (an "Allied", I think) in my PII (Pentium II) rig, and it blew out. Turns out, I had replaced the fan on it, and run the fan wire (molex) outside the PSU, and FORGOT TO PLUG IT BACK IN after I worked on the PC.

Needless to say, the capacitors exploded nicely, due to overtemp. Was a bit messy inside.

Thankfully, no damage to components (Thank God!), but it was a shock and a warning to me.

I always use a PSU with a working fan these days. Cooling a PSU is important.

I would replace the PSU outright, OP, with a QUALITY one.
