You sure about the Direct CU II? I was able to play with one of those Asus 7950 Direct CU II last week and when under full load I was able to hear a slight whine. I first noticed something and then with the case's side door open I was sure it was from near the VRM end of the card. Nothing too loud but it definitely was there. Guess it was luck of the draw (ASIC was only 60% too so that was two points against that particular Asus 7950).The Vapor-X cards such as 7950 all have Black Diamond solid core chokes that guarantee no coil whine. The same is true for MSI Lightning cards, Asus Direct CUII cards, and some MSI TF versions (Power Edition).
No, it's a custom Gigabyte PCB with 6+6 pin connectors. The downside to this card is it has fully exposed MOSFETs. They are not cooled by any heatsink.does that gigabyte windforce you mentioned have the 7970 PCB???
You cannot get an HD7970 with after-market chokes for less than $400 unless it's Asus DirectCUII but those are a huge PITA in terms of driver/black screen of death issues. I think the same applies for GTX670 line too. Any card you buy that doesn't specifically have upgraded solid core chokes, you are playing the coil whine lottery, NV or AMD, it doesn't matter.So, If someone was going to jump on a 7970... what would one want to get? I cannot spend more than 400 btw really... and I don't want to have coil whine either.
I have it slightly in AvP, during Windows Experience Index update screen, MSI Kombuster "Triangle of Death" GPU Burn-in synthetic test when the GPU gets > 1300 fps on a 2D still screen (!!), but not in any other 3D game. The coil whine tends to come out in situations where there is a "still 2D screen" and GPU goes nuts to 500-1,000 fps. However, I cannot guarantee you won't get coil whine on a 7970 Dual-X like mine, it could be completely non-existent, similar or worse.I notice that you have a 7970, do you have coil whine?
Yeh you're right and the HIS 7970 IceQ was really quiet fan wise. Plus I have 3 large fans going on highest fan controller setting and I still did not hear anything loud until the card began to squeel. Maybe others can just write it off but I was trying to do that playing my games I just couldn't take it. Its like a dog whistle almost lol.Ya, it's really sad that AIBs save $3-4 on these components and then release special versions and charge $50-60 extra for them. I bet a lot of people have coil whine but they don't hear it since mild coil whine is virtually inaudible in a blower fan card as the blower fan is louder than the coil whine. Once you go to after-market cards, they tend to be a lot quieter and suddenly you start hearing coil whine. Actually, if you notice from anecdotal evidence, it's usually the quieter cards that exhibit coil whine since their fans are much quieter than the reference blower designs.
Not necessarily. The after market cooled 670's will also have coil whine but like its been said before, if the it has a reference blower fan its most likely will not be heard. If you want a 7970 the Asus DcII, Saphire vapor X ghz, or Powercooler PCS+ Vortex II use premium components. Those cards are highly not going to have any whine. The MSI lightning included too although I've heard one or two people with that card still had whine. Its a bit pricey though.And that is I guess what I'm trying to avoid.
So... Pass on the 7970 in other words right?
The cards themselves are fine, they will fit, it's the adjacent slots that will likely have to be vacated. Run crossfire on 8 out of 10 mobo's out there and you can kiss your sound card goodbye. I shudder to think if you have other, even pricier pcie goodies.will there even be room for me to do a crossfire with the size of these puppies?
