turn off "auto" fan, set it to something you are comfortable with like 60% and then re-run heaven and see what temps you get, then try to OC from there

With the fan running at a constant 60% speed (definitlely NOT quiet) my temps on default 980 MHz running Heaven Benchmark are between 65/66°C surely that isn't right?

Whats up with pricing of the 670's, it was £341 yesterday when i looked now its shot up to £370 for the Windforce.... Thats ridiculous, it can be had for £340 elsewhere.... :confused:

At that price i wont by from OcUK out of principle.

It was on a one day only special I believe

as pgi says, he was running 1350mhz boost clock 60% fan = 60C

it would seem that you've got a bit of a lemon as far as windforce cards go, however compared with reference type cards 1280 at 70C is still pretty good and the FPS difference between 1280 and 1350 will be 1-2FPS so not worth worrying about!

just set the fan to something that is acceptable to you and leave it at that and whatever clock speed and temp you get is what you get

there was one other person that topped out at 1280ish with 67C, so it's not unheard of

Little tip for everyone, put your efforts into overclocking the memory, it seems to give a better performance lift than the core boost, should be looking at 7000 effective minimum on these cards.

I just tried 1:1 and with my 1293 clock boost it reached 66°C/66% fan speed, I guess I may as well run the set auto fan, peak is 47% fan speed for 1280 clock boost - quiet as a mouse.

Is that as a percentage of the total clockspeeds?

So for instance a 20% overclock on the memory would give 12% better performance in benchmarks, while a 20% increase in core clock would only grant 8% overall FPS boost?

There was no mention of a one day only deal anywhere including on the actual product and I'm pretty sure it lasted longer than a day. I'll be picking one up somewhere over the next week or two. I was intending to get it at OCUK but with atleast two of their main competitors selling it for £340 I am not impressed with the 10% mark up.
 
Am I right in thinking that the Windforce 3x uses a reference GTX 680 PCB design? so a reference GTX 680 Waterblock should fit on it just fine? if so, for anyone that has done it is it relatively easy to remove the Windforce cooler? as I cant seem to find any guide on it so i'm guessing it's relatively straight forward? :)
 
they were on special over the weekend.. i went to order 2 and it said only 1 per customer! tempted to phone now and ask if i was to order 2 if they would honor the price they did over the weekend!??

Almost what I was getting at, I noticed larger performance increases moving my memory higher than the core boost, you can gain over 1000mhz effective on the memory, only 200mhz average core, and that's if you have a good chip.

I'll try show some benchmarks later of core vs memory, once I've had a fiddle with nibitor that is ;)

Yes and yes.

you just unscrew it and it comes off

no increase in overclocking potential though, the windforce cooler is already very good and water doesn't seem to be adding anything in terms of OC
 
It's very easy to fit a 680 waterblock to the windforce, but as Andy pointed out there was very little to gain putting the card under water.
 
So are all the reference coolers exactly the same then? i.e. all noisy?

Should I get a £310 670 now and wait for more cooler options to come out or just get the Asus for £380? :eek:

Hint: I don't like noise :)
 
the kfa2, gainward, msi and zotac reference cards all seem to be the same - exactly the same as nvidia's reference cooler... the EVGA basic one looks a little different, the fan is smaller, both the EVGA regular and SC model come with a high flow bracket on the rear instead of the standard one but no one is quite sure if the heatsink on the EVGA non-SC is the same as the slightly bigger one on the SC (I wouldn't be surprised if they were the same given all these other similarities)

the nvidia reference one has been commented on as being audible, though a whining noise could be down to some faulty fans rather than actually inherent in the design

the windforce is the best overclocker on average and also stays quiet (it was also on at £340 but has jumped back up to £370)... the asus is not a particularly good clocker and also doesn't stay all that cool while OC'd

I would say that overall the prices on the OC models will be coming down (again) as time goes on, so could be an idea to try a reference one and if you don't like it DSR or sell on to get one of the OC models
 
:( can't get my windforce past +75 gpu clock without crashing in heaven, i managed +80 but with fans set @ 55 which is 'audible' but then adjusting the mem clock it crashes again. temps aren't great atm i think where i've got it right over the psu is not helping, it just touches the fan clips on the heatsink if i use the 'first' pcie slot (P8-Z77m w/ NH-D14).

was considering a backplate / electrical tape as so i can move it up away from the psu, would this work and would it help? i have a feeling that it doesn't like hitting 70c...
