New Power Supply Help

[arealsnek]

Helloo.So i recently received my new Seasonic S12II 620W PSU for my gtx 1070 ( ASUS DUAL NON-OC). The old one burnt out.

So it s all working but when i opened up overwatch, after about 10-20 seconds, my PSU fan went crazy and really loud.

And just like the old one, i can hear random noises like hitting/grinding. It does have a smell coming from it, either very little burn smell or the new product smell or maybe it s because of the old PSU.

I immediately shut my pc off and i started it again and now on desktop/youtube etc it s all quiet/cool etc.

What could be the problem/what should i do?

P.S I can record the noise/psu etc if it would be helpful.

EDIT Gimme 5-10 minutes.

Recording on the way. Btw the usb failed at first when plugging it into the front case usb. Could the box thing that leads the power to the power supply when you press the start-up button cause problems?

@herman mcpootisu can answer this right

It just did that again. I was selecting some videos from my plugged in phone and i just heard a fan going very fast.

On the backside of the PC it didn t feel like overheating/warm but rather coldish.

Restarted my pc and everything is quiet again.

I d like to test it in a game with HWMonitor but i m afraid it ll die or something...

GPU is set to fanless mode.What could it be?

Halp please

Maybe the fan goes bad. Try tier 1 or 2 PSUs.

Do you want suggestions? EVGA supernova G2/3.... you can not go wrong with those if budget is not a major issue.

My guess is that the fan cable in the PSU is getting grazed by the fan. This is a fairly random occurence and happens even in very good PSU's (IIRC Oklahomawolf had this happen in a G2 once, though the G3 has solved the problem).

 

I'd check if the noise persists when you manually stop the PSU fan.

The PSU is new, i just bought it after the old one died. It s a good PSU, tier 2.

The thing is, that the old one was doing this aswell but nothing happened with my old graphics card ( when i had the old PSU ).

I couldn t find any youtube videos with my exact noise/problem.

My guess, a loose screw or maybe it s hitting the case or something. 

 

Would it be safe to start playing something or will i risk having in die?

btw @Nimrodor, you mean i should open the case while the computer is running and stop the fan with my hand?
