Hello everyone, I have a general inquiry for the 3080 TI XC3 since it looks like my queue time is coming close and there doesn't seem to be a whole lot of info regarding the card compared to its FTW brother
 
Owners of the card, what are temps and noise like? I've heard the 3080 XC3 gets pretty toasty and if they just reused the 3080 cooler for the 3080ti (like some other manufacturers have done from what I've been seeing) I suspect the 3080ti will be very hot as well (with lots of noise to go along with it). I would be using it in an ITX space, so heat will already be a challenge as is

Will I need to get new thermal pads, and if so what sizes? Since this is the more "budget" of the 3080 ti family I imagine the thermal pads are more suited to longterm use and won't be the most top tier performers as a result. I helped my cousin repad one of his cards so I feel comfortable tearing apart the card and adding them
 
Sorry if this is the wrong place, just not a lot of info about this card is easily available like its premium FTW brother

    It's not bad. I average 77-79C in a typically hot day. It can be a bit noisy at 100% fan speed (I have a pretty aggressive fan curve) but since I have 5 other case and AIO fans running, it blends in :). I would like to know if it's worth re-applying Thermal pads and paste as well.

    Noise will most likely be an issue if you want to keep the temps at bay.  Just make sure you have ample of internal case airflow to feed the GPU in such a confined space.

    My 3080ti XC3 runs in the high 70s in tasking games at 60-70% fans speed. If I turn the fan speeds higher than that it is to loud for me. I have not pulled the card apart to repaste or swap pads. I have seen up to 366 watts being pulled at times by the XC3 card. The FTW has a bigger heat sink but also can pull 450 watts. I do not have any personal experiance with a 3080ti FTW card for compairison though

    That seems especially hot, have you tried undervolting? Almost slamming against 80C even at 100% fan speed seems like a problem with the card, I don't know the measurements of the pads but I'd definitely be looking at pads and paste for that.

    Have you undervolted at all? I've been told the 3000 series undervolts like hell and that might help keep temperatures at bay. Beside that, how would you describe the fan noise up till that point? My current gpu fans whine when above 50%

    I would be looking at a ftw3 if my queue for that wasn't a day late, so the XC3 is the option I have here.

    Yeah I'd be putting this in an ITX case (Formd T1) so temps are already gonna be an uphill battle unless I can get a hybrid kit (whenever those get back in stock lol)

    No, I have not tried to undervolt it. This is with the power target set to 105%(max) and GPU temp to 91(max). The fans do start to get kind of loud over 50%/2kRPM. I came from a hybrid 1080 card before this one and miss how quiet the system was before.

    Well then the higher temps and fan speed make more sense knowing ya have it at a higher power target, makes me feel a tad better about the cooler lol. Hopefully once I get mine it'll be a bit on the quieter side, might have to get one of those hybrid kits otherwise

    i get mostly the samt temps but my gpu runs a litle to hot some times any tips on how to prevent this?

    Ambient room temps are mostlyl 25-28c and outside is like 35-40c. The card is undervolted. I tested again today with AC on at 19-20c ambient room and went 71c max temp.

    Would you mind sharing your undervolt? Its looking like repadding/repasting might be a good option to bring down temps further, but I'll have to do some research to see what the sizes

    pads shouldnt do much difference if it is correct thickness , proper paste should improve it few degrees hopefully

    I was operating under the assumption core temps *and* vram temps decided fan speed, a newer paste should help a few degrees but fresh pads (given the stock ones are bad anyway) could also do wonders to keep temps/noise down

    So received my 3080 TI today and did some testing, nothing super scientific but might help those were in my shoes and wanted some info.
    Stock Settings playing Cyberpunk 2077 for 15 minutes (4k, RTX Medium, DLSS Quality, Mix of High and Ultra Settings) and GPU temps topped out at 76.7C and Fans topping out at 1900RPM (where they stood at for the last 5 or so minutes of the run, poor GPU). The noise I would describe as kinda audible but not "so loud you think the card is broken" loud, its certainly bearable. I'm using an ITX case where the gpu is facing me, I imagine in a bigger case with better airflow the sound would be drowned out by other components. At stock the card drew 350w all on its own, so proud.
     
    In regards to my worry about thermal pads, I am happy to say that the stock ones are fantastic topping out at 86C under the Cyberpunk load (which is a far cry from the 90+ I had heard for other cards). I don't have the measurements for if someone wants to change them out sadly but honestly unless you just really want to I don't see a reason to want to change them out. I'd only really consider opening the card up for maintenance or for a hybrid kit installation (which I hope gets restocked soon, I would love to try one)
     
    I have also heard the 3000 series is very good at undervolting, so I tried to make the best undervolt profile I could using the average clock speed that the stock settings had (1770-1800mhz) and ran Cyberpunk again for 15 minutes (not the exact same gameplay but I tried to do similar missions and traveling). Performance ended up being about the same, if there was a difference it was 1-2 frames at best. So at 793mV and 1785Mhz temps topped out at 74.1C and fans around 1790RPM (this time it gradually rose and spent the last 5 minutes creeping from 1700 to 1790RPM). The fans sounded a bit better, there was a specific distance I could sit and I'd hear a gritty sound (best way to describe it, it didn't sound like the fan was getting caught) but otherwise just sounded like the 1900RPM but slightly quieter. With this the card drew 305W max, which kinda surprised me since I expected a bit less wattage after such a dramatically lower voltage. Its likely I could try to lower the voltage more, but that would be for another time. Memory temps under this config topped out at 84C.
     
    I don't have a lot of cases to test my theory, but I think it'd still be safe to assume that a bigger case that has more intake fans would help this card perform better. That said given the case, I am pretty impressed with the performance of the card. I think with a bit more fine tuning I could get it to where its bearable enough to use without headphones. That said I am after testing this very curious to try out a hybrid kit, so hopefully those restock soon to how far the card can stretch its legs.
