Your OP still says it...I see the update but... Why not straight up correct it?
Search this DB for people that can (easily) have stable benchmarks using LN2. Thats the ONLY point to use that stuff is to get through benchmarks.
Also, coil whine isnt caused by excessive power (I suppose it can be?). You can have a normal load run through a coil and it still whines. Hell I have had cards that have done this on idle even. The way you wrote that tells me its a direct correlation.
You look a little green Q....
A fair question, my friend.
There's a lot of do's and dont's to writing a news article that isn't apparent as a reader and I've been learning a lot from writing these for TPU.
Generally, when an article is updated or corrected, it's considered good practice to leave the original text in and just put an update in there. In the case of TPU it also has the benefit of keeping the forum comments consistent with what was initially posted - think all those skeptical cats.
And the 590 jealousy? Just a bit of humour that a single 580 can do better than a 590 with such a screaming overclock, lol.
The LN2 thing was another joke. I have an irreverent writing style.
Yes, the coil whine is indeed caused by more power going through the card. Some cards are worse than others and I think it basically depends on the quality of the components used how much stress they can take without making a noise. My 580 for example is really quiet on whatever gaming load I throw at it (fan ramps up, ok) and even with the Unigene demo benchie (fan ramps up a lot, especially with vsync off). However, run Folding@Home and after about 30 seconds, the most annoying, irrritating whine comes from it, making folding with it impossible.
Just squeezing and gently wiggling the card affects the noise too, so it's definitely some poorly made/attached component(s) doing this. Mine is a standard reference design with a tiny factory overclock, which I haven't overclocked further. I'd expect that Classified card with its beefed up power circuitry to take a load like that in its stride and not make a noise about it.
