Twin frozr 2 vs twin frozr 3 gtx 560 ti temps

post #1 of 16
Thread Starter 
Is a 10 degree difference under full load normal between a gtx 560 ti twin frozr 2 oc (880/2100/1V) and a gtx 560 ti hawk twin frozr 3 (950/2100/1.075V)?

Absolutely, even though the Hawk's fans push out 20% more air, the card is overclocked quite a bit.

I actually RMA'ed the HAWK because i tought it was way too loud and hot. I had to wait for it soo long that I bought a twin frozr II in the meanwhile. While playing black ops the Hawk got up to 76° while the twin frozr II I have now only gets up to 62° and remains really quiet.

Is there a possibility to SLI these two cards when I get the hawk back and maybe flash the Hawk with a twin frozr II bios so that both get even as hot?

How much does a temperature of a graphic cards increases when running SLI instead of a single card? About 10° for top card and 5° for bottom?

Depends on how close the two cards are installed on the motherboard. If they are installed right next to each other, then expect a temperature increase like you mentioned. If there's a PCI slot in between (or enough of a gap), then the GPU temperatures will be a little better.

I have to agree, the Hawk does actually get very loud, but, it's still amazing and was worth every penny.

i'm still a bit dissapointed. MSI promises it to be a silent and cool card but in fact it doesn't.

Is it possible to SLI a twin frozr II with a twin frozr III?

I have a MSI P67A-GD65 and there is one slot in between...

I don't see why not, but, of course the Hawk would be limited to the TFII speeds

That 1.075v setting for your TFIII hawk is rather high; no wonder it ran so hot. I run my TFII at 950 @ 1.032v and the noise level isn't so bad, but it definately is not silent. If you plan to run SLI, consider using an OC which both card can handle comfortably. And make sure you have very good case airflow since most the heat gets dumped into your case (the only bummer about the gtx 560 ti cards).

Well 1.075mv is what it came with stock. So i'll guess i'll have to undervolt it? Isn't there a way to modify the bios with the voltage and core/mem speed settings like the twin frozr II OC?

I'm gonna get some scythe gentle typhoons ap-14 for my Antec P183, 3 intake (2 in front of videocards and 1 bottom chamber for HD) and 2 outtake (1 rear and 1 top). Will this be sufficient? What should be the maximum temperatures I should let them reach?

That fan setup will handle your potential SLI, just make sure your exhaust fans are keeping up with the air flow of the intake fans. If all is setup well, those SLI TF cards should be topping out in the low 70s c, though usually they'll be cooler than that. I don't know anything about custom bios voltage mods, but you can experiment with MSI Afterburner to set voltages and clocks; Afterburner can be configured to run your setting at boot up.

If you are really unhappy with that TFIII hawk, selling it might be worthwhile. IMO, SLI only makes sence if it's the ONLY way to get the performance you need (read: huge resolutions).
