For Precisionx have "Auto" checked, click "Fan Curve", Click the software control checkbox, and then set it up something like this

Click and drag to create/move a point, press delete to delete a point.

You need to have it start on boot to keep your OC and fan profile active.

So my Asus Direct CUII TOP came in today. Looks like I am one of the many lucky ones who got a perfectly performing card. biggrin.gif Below are my results....

Core i7 2500k @ 4.4 GHz
16GB RAM
EVGA Precision-X
Win 7 x64

Out of the box my GPU clock was sitting at 1241MHz, and I was able to run Heaven without any issues. My Heaven FPS after benching on full settings was 46.1 which seems to be about normal for the stock TOP. Below are some results from my OC trials. For all OC tests, the Power Target was set to 117% although I never noticed the power going above ~112% usage.

+10 to core (1251MHz) +400 Memory = 48.8 FPS
+15 to core (1256MHz) + 600 Memory = 50.2 FPS thumb.gif
+25 to core (1266MHz) + 650 Memory = 50.5 FPS
+35 to core (1276MHz) + 600 Memory = 50.4 FPS (yes, a reduction... maybe because of lower vRAM frequency rolleyes.gif )

I tried to go +40 to core, but Heaven crashed and I am too lazy to go +36 to really find out what she had left in her. Given my tests, I will be running at +15 to Core (1251 MHz) +600 to Mem with a 105% power target as I see that being my best improvement with the lowest overclocks.

Thus far, I am loving the card. I ran a little BF3 on ultra and for the most part on Caspian Border with 64 players, it remained between 70-95 FPS with Ultra settings with FOV at 74. Another thing that is great about it is how quiet it is, even around 80% fan. Compared to my SLI GTX 460's, it is complete night and day difference.

The only thing I am not happy with is the cooling. I have a CM HAF-X with all the fans going in the correct directions. I was able to keep my GTX 460SLI at ~66 Celsius under full load, but can only keep this single card at 69/70 Celsius? That is annoying. It says right on the box it is suppose to be 20% cooler than the reference cards, but I am not seeing it.

Does anyone else notice this... During Heaven (Full Screen) Precision-X does not update the Fan Speed analog number %, but does update the grey graph representing fan speed. (running on a second monitor). Not sure what is up with that, may try MSI After Burner to see if theirs updates real time like it did with my 460's. Makes me wonder if the fans are actually cooperating with the curve. (Auto is checked when using curve)

Lastly, but not least, if anyone has this card in a 5760x1080 setup (single card), and plays BF3, please let me know the best settings you can pull off while maintaining 40+ FPS... Next move to upset the wife will be 2 more monitors. biggrin.gif

TL:DR Thanks!

I have a pretty aggressive fan profile. I have it set to hit 80% at 60c since it is so quiet. And this thing sits at 58-59c in my case. With fairly weak airflow at that. Your temps sound bad if the fan is cranked up on the card. My ambient is about 70f.

Right on thanks for the reply. Something I can compare to... It is probably my ambient. Above the garage + wife keeps the house at a sauna level. It is 78 degrees currently. That may have something to do with it tongue.gif

I will try to up my fan profile to be more aggressive like yours. Long as I can keep it under 70c I am a happy camper.

The graph might have some delay, have you tried using the onscreen display to show the fan speed?

Well, i just debunked the myth that the throttle point on the Asus 670 is at 70C. After thoroughly testing it by pushing the temperature up to 81C, i've found that the first throttle point is at 76C (not 70C like the reference model) and the second throttle point is at least above 81C. I didn't feel comfortable going over 81C with my brand new $430 card at this point tongue.gif (maybe later).

Here you see i'm at 71C and my temperatures are progressively increasing yet my GPU clock remains at a steady 1262MHZ:
332

And here you see when i finally hit 76C i drop down by 13MHz to 1249MHz:
340

So it looks like Asus was pretty damn close to setting an optimal fan curve as far as i'm concerned. With the default fan curve and a hefty overclock (+720 on the memory and +18 on the core), i was still rarely hitting 76C in the most demanding games.

Anyways, with this knowledge now, i think everyone should set their fans to go up to ~79% at 75C (79% is what it took for me to stay below 76C in furmark on my Asus 670), then have another point at 82C at 100% (your GPU will never get this hot anyways, it's just a safety net), and then a point at 68C (average gaming temps for me) set at 62% and then the last point about 2C above your average idle temperature (31C for me) at around 21% (this keeps the fan steady at idle so you don't hear fan ramping with every 1C increase).

Here's what my fan curve looks like:
472
So in typical gaming my fan stays around 62% (completely inaudible for me) and then goes up to 79% to keep me well below the throttle point in the most demanding (ie, hot) parts of a game. Then at idle my fan stays constant.

Edit: The throttle point on the Asus TOP might actually be even higher than 76C. I think i was being throttled by power percent rather than temperature here. I just redid this test here and i didn't see any throttling until above 79C.

Thanks for taking the time to post that... My fans are fine smile.gif Ambient temps in house dropped for a real test and all is good.

The OSD has much more delay than the graph does. When i had it set to show the GPU clock frequency, i never saw it drop at all, but when i checked the graphs, i saw split second 13MHz drops. At least that's what i observed when i was doing my temperature tests above. So either the OSD has more delay, or it averages out the numbers (ie, smooths them) so they aren't constantly changing 539839 times a second. So either way, the OSD is a poor way to get real information compared to the graphs.

Ok am I missing something here. Your getting 69/70c on a haf x overclocked? I'm getting 77c playin bf3 on ultra 1080p @ stock factory oc. And when I put a gigabyte windforce gtx670 it never goes past 70c. The gigabyte stays at a constant 1150 while the asus stays around 1189 as soon as it hits 75c

Redo the TIM job. Seems kind of highish temps since your 460s were running cooler.
