4090 FE received today. Very-little coil whine - it's probably the quietest high-end card I've owned in 10+ years (and I've had a lot). As an added plus, the 4090 FE has to be the most beautiful graphics card ever made.
This was actually my third 4090 within past 2-weeks. I purchased a B-grade Zotac from a competitor which also had very-little coil-whine. Unfortunately the Zotac turned out to be faulty and was promptly returned (core clock would randomly drop to 300Mhz and stay there - even after restart). I then made the mistake of purchasing a "Reconditioned - Excellent" MSI Suprim X from a big electronics reseller on the big auction site. This arrived with a severely-warped PCB (obviously used without an anti-sag bracket), covered in dust and grime, no-accessories, and packed loose within a battered non-OEM box. I didn't even install this one - it got returned immediately. After being burned twice I did what I should have doen in the first place, bought a brand new one. I will only purchase new or from trusted forums (like OcUK) in the future. I think too-many B-grade and so-called refurbished high-end cards have had tough lives. People on here seem to look after their stuff. Tiny-rant over. Happy in the end.
