My CS750M had only been in my case 1 week and started making these absurd loud fan noises that were not normal and extremely annoying. I opened up the case and turned the fan upside (was downside previously) had the PC running for 5 minutes now and no noise... Have I solved it or should I return it?
 
Solution
Fan should be down if there is a ventilation grill on bottom of case.

If it can't operate with fan down return it needs to be returned , it's poor quality to begin with.

Get a refund.
Sometimes the fan can HIT something in the power supply case when upside down but work fine the other way.

I don't know if I'd necessarily return it as that can be a huge hassle and you have no power supply in the mean time.

You can always return it later within the Warranty period so maybe just hold off.

I flipped the PSU around this morning again, I only flipped it upward because me and my girlfriend were watching a show and it was over powering the sound, even when it was loud... The PSU has not made the noise again and has been running for 20 minutes, maybe it was just getting too hot because it had been running for roughly 14-16 hours straight?
