1. My longest used blower style cooler was an EVGA GTX 570, and the RPM was pretty high; which made the graphics card unnecessarily loud, but only reduced temps by a degree or two, so i wouldn't be worried about low RPM's on your 770 (that's speaking from experience)

2. Looking at your case, i suggest you stick to your blower-style cooler. Unless you have an adequate way to exhaust the hot air an aftermarket cooler will store in the case, and also have a way for cold air to come in, blower style coolers would be the best option for you. 63c is VERY good for a GTX 770. Here in Texas it gets pretty toasty during the summer so i used to have my top GPU hover around 86c on air @ 1293Mhz while playing demanding games. Other people on the forum you're talking about could have colder ambient temps, and that also makes a great difference in overall temps.

If you don't already have fans blowing on your graphics card, do that, i believe that should help keep temps under check if you are thinking of OC'ing, and note that anything under 85c is super fine, your GPU would live a long happy life at that temp smile.gif

Hey thanks for your answer! biggrin.gif

So, I managed to get 63c, but that only was today after playing a bit with the EVGA Precision software. Before that, Unigine benchmark and pretty much every demanding game would make the Card go to 80c (at least the ones I've tested). For the card to be 63c the fan must be at 75% max RPM, that's more than 3000RPM if I recall correctly, based on the readings on Geforce Experience. VERY LOUD!.
If I leave the card control the fan itself it will go up to 1850RPM approximately, which is not so loud, but temps will be high. I know the card will sustain it without problems, but other components near the card (like the SSD) will be getting some of that heat, which is why I don't like it.

That's why I was considering one with open-air cooler, in the RVZ01 thread one of the guys reported 58c with an EVGA ACX on load, without modifying the fan curve. That would equal almost the temps I got without the tremendous amount of noise :S

I'm in Puerto Rico, it gets very hot here (not as much as Texas though), but right now the nights are still cold, and that's the only times I've been able to test the new toy tongue.gif

Hes right for most part im also in Texas unless you water cool the entire system...during summer time you either lower the overclock and voltage some or you simply deal with the added fan noise and temps...the gpu's especially can run mid 80's for hours without hurting them at all just keep on eye on vrm temps if possible or lower your memory overclock.

Also the after market cards dump the hot air mostly back into the case and or upwards so always try and get a fan on the back pulling out as well as one or two or three up top...for sli I usually do reference cards on air for time being until gpu blocks and install my top radiator pulling air out as well as a rear 140mm in any case...and a rad on the front pulling air in or just fans ietehr way thumb.gif

remember as well that aftermarket coolers will increase the inside case temps including the motherboard so you want to keep on eye on the mosfets also...most people don't look at mosfet temps anymore but if your running a higher voltage overclock you want to keep on eye on them for lifespan of the motherboard etc.

My gtx 770 is a 680 PCB, clicking on either (red or blue) button won't do anything. I tried to set voltage in AB and it didn't work. I tried the second program and it won't go past +12 mV (looks like it is blocked by AB). If I put 20, it maxes at 12 and indicate 12.

Also, I am unable to reduce the voltage in AB... Wonder why.

This Zotac 770 has over voltage support

about my bios yes i'm back to the original and bios from msi Site

still the same ... RPM always at 9000-8800 TDP never been beyond 75% with 1.4 V and 1489 mhz core and 4005 Ram and this is not normal because the same with stock clock 75 % TDP ....
and now both card have the same TDP problem on original bios
under sli mod when i rapidly change multiple windows for a long period of time a small tearing appear always in the same position in the monitor number 4 for about 0.5 s or less i could not even record it with phone ....
no gaming problems no unigine valley bugs no furmark bugs
100 % OCCT tests for Gpu and VRam
i'm clueless about the rmp ... 9000 ... why ??

i have flashed both Gpu about 100-300 times ... i don't know anymore

up : Fans speed is unchangeable on First GPU
used bios , by loading card to max temps to change speed...
and the same with MSI AB evga X .... riva ... all tools
the fans runs quiet as a mouse
the other card is fine the fans boost up to 100 % when i set it .

i think My pwm circuit is dead ... Fan speed is always the same .... help ??

What OCs are you guys (and girls!),able to get?

And how important is the RAM clock?

With the core clock I was able to get +60 on the gpu clock together with boost it was around 1250, and +300 on the vram and ended up around 1900.

With the flashed bios I can go much higher on the gpu up to 1300+ but on the ram I can´t put more then 1800 or it crashes.

VDDC_Generic_Detection = 0
VDDC_NCP4206_Detection = 4:20h

Did that, but all it does is I can't touch the voltage (no slide in AB) and it seems to be fixing the voltage at max (1.187V) always even when idling...

I never heard anything like what you experience. All I can suggest you to do is to re-install drivers & software. Try Nvidia inspector to see if there is the same reading.
The easy solution is to try the card in another system, if you can reproduce the issue then it is likely the graphic card. You might have a sensor that gone wrong.
