Firstly, hello. So this last year I have been slowly upgrading my PC from an old i5 2500k........ A GPU Gigabyte 1070ti. Mobo Asus z270-a and cpu i7 6700k. 16g of HyperX ram. All a bit dated but they are what they are.
My old PSU had been getting louder/hotter as time went on so middle of June I bought a EVGA 850 GQ. Everything seemed fine.
Then at the end of July. I turn on my PC to find my Corsair H100i had died. So I got a replacement, H100i pro. From the word go I had what I thought was air in the system so I tolerated the noise, a buzzing in the pump. It did get quieter but continued and then I started to get the occasional knock/bang, not loud but it was doing my head in. A forum recommended that I try to mount it vertically in the front of my PC. The constant buzz faded for the most part but these annoying bangs continued. They would only happen under load but so random that I could never quite work out where they came from and had assumed it was the water cooler. I put up with this for three months, until recently when under load not only would I get the bangs but a much louder buzz with the AIO cooler.
I talked again to some people on a forum and they urged me to investigate the PSU.
So I contacted EVGA support a few days ago, basically saying what Ive just said here. The reply was short, "Most likely the Noise is coming from the pump of the Hybrid pump. Regards EVGA"
I bought a new AIO water cooler. I decided on a Arctic Liquid Freezer II 240. Partly because of the good reviews so far, the price and that it is powered by the CPU_FAN header, not a SATA cable like the previous two Corsair AIO coolers were.
After it was installed today, I chilled and watched some videos and Twitch stuff for an hour. Then went on to play WoW to see how things went under load....... A short while later ........ the knocks were back. SIGH . I got my GF to sit right next to the computer and listen as I played for a little while longer. She knows even less about computers than I do but she clearly pointed out, with her ear right next to the PSU, that the knocks were from the PSU.
It isnt a coil whine, not at all. It's a metallic knock, a bit like if you knocked a side panel with your knuckle. Not a light tap, a knock.
Would this be an issue for you guys? I feel like it is and I certainly cant afford to buy all new components if the PSU blows up and takes everything with it.
I contacted EVGA a few hours ago. Hopefully I will get some sort of helpful reply.... Do I try to make a fuss if they arent overly helpful?
