Its just normal, definitely quieter than the ref 6970 that it replaced and that wasn't overly loud either. If you were after silence then yes you may find it audible, but you shouldn't be buying reference cards either.

Forget about the 70c-80c thing, this card is tuned to hit 80c where it will lower the voltage slightly so the fan runs at a slightly slower RPM thus is quieter. The max overclock you want to look for is the one when its running at this state, so mine runs at 1190-1200mhz when looping Heaven at 80c. Whilst running BF3 with a slightly lower GPU usage and lower temps it runs at about 1220mhz. Any higher it will crash.

I only mentioned it because a certain someone on here was making a massive deal out of the 15mhz it costs you... to me 0.1 of an FPS doesn't matter if it means saving £50, particularly as I plan to SLI them sometime in the next few months

80C also doesn't bother me, my 580 phantom got up to 85 on full chat so I'm again wondering why all of a sudden 80C is a big issue for some people :/
 
Nice, give that memory a push, as the cooling is good you should be able to manange +550 or more, have my memory currently sat at +750.

What boost clock is +185 giving you?
 
Boost is over 1300MHz, but it coming down to 1296MHz when 65C and a bit lower when 70C
Max temp 75C in Heaven with these clocks, and as I said 57% fan speed :) - Lovely card.

This card is a bit different regarding boost clocks, don't know why is doping down clock when not even 70C.Also voltage is dropping a lot, it wasn't like that in my KFA2 card - what it could be?

I had this on one of my 680's... try starting from +10 and go up slowly and look at the boost clock... i did start from 150 and it would run and boost but it kept hovering around 1084mv instead of 1175 and the boost clock would fluctuate quite a lot too... I put it back to +100 and it then boosted higher and locked itself at 1175mv

when I was getting low voltage I actually saw the power target climbing much higher than when I used a lower offset and it then used a higher boost and higher voltage, but the power target was lower

have a benchmark windowed in the background to stress the gpu and then play with precision in the foreground so you can watch what the mv and boost clock are going each time you make a small adjustment

Had a play doing this, didn't really do anything for me though, probably as the windforce is locked from stock at 1.175v. Still puzzling me why my power usage was 10-15% higher on air than water, don't suppose having no fans to run would effect this?

Edit: A slight tweak on the memory and a 200mhz increase on the 2600K and i've smashed the P10500 mark in 3dmark11 :D

it could just be that as the chip gets hotter it gets less efficient, so it needs to pump more current through to hit the same boost clocks, now that you have the chip running cooler all the time it's not drawing so much power even though it needs the voltage, but yes if it's reading the the power draw of the fans as well then that could also influence it

what offset are you running pgi? Blackwhite's seemed excessive to get to the boost he's reporting and that was the issue I had on a 680 (way too much offset caused voltage problems without causing driver reset errors but it did cause boost de-clocking even though temps were low)

doesn't matte with or wqithout OC card is doing the same, co thi si not an OC issue, just card itself.
it is not a problem for me, I can leave with this :D
 
My offsets are:

Power - +111%
Boost - +165
Memory - +750

Any higher on the memory I get artifacting, but a 1.5ghz effective increase from stock isn't bad going :o

But my stock boost is 1189mhz, if someones stock boost was lower they would need a higher boost offset to hit that 1300mhz mark.

As it stands even some decent clocking 680's are having trouble keeping up with my 670 :)

No, the 1110 is the advertised boost, the actual boost should be 1215 Mhz with a 1006 base clock.

1727 is the ram frequency.

The black squares around the GPU are the memory chips, not the memory controller.

No such thing as an "actual" boost on the 6xx series. The advertised boost is the minimum all cards can achieve but everyone's end boost will vary since the cards tend go go near their limit when boosting anyway. It's why some people have huge boost out of the box and others don't.

My Asus gets pretty toasty in Diablo 3, just hit 80c with the fan @ 65%, still quiet though, I took the side of my PC and it only dropped to 76C, core seemed to stay around 1097Mhz.

Ambient room temp of 23.5c.

Not sure how you're managing to get temps that high in Diablo, with a 23c ambient temperature and with a Windforce card the max I get in Diablo 3 is 54c, heck the card doesn't even boost above 980MHz cause it's not needing to go higher

I do have v-sync and forced triple buffering via D3DOverider, perhaps that's why, I'll try again without it.

Can you hear the fans at all on your windforce while running Heaven?
