Re: GTX 670 launched

edh, thanks for your suggestions, but it seems that for now that software is a bit unreliable with GTX 670, so I'll wait.
However, I have bought and just installed an AC Mono Plus on my GTX 670, and here are some results.
It idles at 30% fan speed, which is ~900 rpm, not acceptable to me, I want under 600, considering that idle temps are just 30C.
In Furmark extreme burn it reaches a GPU temp of 60C at 1140 rpm, with a GPU speed of 915-928 MHz.
The large VRM heatsink also reached 60C, but I had to open the case (P150) to keep a thermal probe touching it.
With the case open the GPU temp dropped to 55C. There are some issues when installing the Mono Plus though.
I was unable to put heatsinks on two of the memory chips, because the Mono Plus's base is too large.
Actually I used some Thermalright heatsinks (not the ones coming with Mono Plus), that have a sticky tape on them.
And after realizing that I can't install the cooler with them I had to rip them off the card.
So don't permanently glue memory heatsinks (onto two of the memory chips with this issue) before installing Mono Plus.
Also, the PCB is bolted to the back of the card through the stock heatsink's shroud. Without the shroud the bolt
has nothing to catch into, and my card is sagging a bit. I need to find a thin bolt and nut that would fit instead.
PS. Since I'm keeping the card in my backup PC, I gave Afterburner a try, but I was unable to lower minimum fan speed below 30%.
I set the fan ramp-up to 10% at 30C till 50% at 60C, and more afterwards, but in practice nothing happened.
