Acer BiFrost A770 high temps/rpms

looks like you can add 2 lower fans as intake to help cool the card, and what resolution are you running ? and what games have you tested it on? i have a 3070 but only run at 1080P so it never goes over 54C and it goes as low as 48C all depends on my room temps, with my main game, Days Gone on max settings, with NVidia game optimizing on and auto tuning enabled.

Gamers Nexus did a review of this card few months ago. If you haven't seen I think it is worth a watch. Tech Jesus had lower temps and a lot lower RPMs than you did, but most likely the tests were run at 1080p. Naturally ambient temp also matters - Steve and his team conducted tests at controlled 21C.

To me the GPU core temp and extremely high fan speed (I assume the reading is from the smaller Delta fan) point towards a bad contact between the GPU core and heatsink. There's only one way to fix it and that'd be to do a repaste. Thankfully it is easy to do according to the video.

I honestly do not know. Some manufacturers allow repasting and repadding, while others don't. Maybe ask Acer technician directly to have it in writing just in case?

Usually after any mods the card has to be returned into original configuration before sending it back for a possible RMA. So make sure not to lose any parts etc.

If you end up doing a repaste job, please report back about your experience and what happened to temps and RPM. Thanks!

Good luck!

well, im no expert, but it could be the case causing the higher temps, i know in the predator den there are a few members talking about that card, maybe ask them in there what temps they are getting and what kind of case they have, im sure the case size matters alot for cooling, and ive always been told, the higher the resolution of your monitor the higher the temps will be, there is a guy that has the same pc as me, with a 4k monitor and his temps on his card run 10 degrees hotter using the same exact settings playing the same exact game as i do @ 1080P.

well, mines air cooled as you can see, and with cinebench r23 running the multicore 10 minute test, my cpu temps are 64C, and i have no issues with my cpu and gpu, both run at 100%, i checked the bottleneck calculator mines at 0.04%, now it could be your ambient room temps, im in a basement in ny, in the winter mine runs 46C-cpu and 54C-gpu and in the summer with central air going, they are 40C and 50C with side panel off 38C and 48C, in the winter my thermostat is set at 68 and 68 in summer lol, so yeah, a lot factors in with our internal temps, now i always run mine with all the fans 100% also when gaming for maximum cooling.

mines a 12700F that came with my predator 5000, and its a 2022 model, with the stock cooler i got 85C on that same test and when gaming i was at 63C, that's why i upgraded to the Noctua NH-U12A its amazing i love it !!@!! and of course, added 2 fans up top as exhaust and maxed out my ddr5@64gigs-crucial 4x16@4800mhz, removed the hdd caddy and cpu bracket that blocked air flow to the gpu and cpu, i think its all helped with the temps im getting, so after reading what you said, maybe its that small case limiting the cooling, mines a large case and the more i did, the better and cooler it has gotten, especially when ya see my temps changing significantly from the stock cooler to the Noctua, it was a 15-20C difference.

well i assume that it's the fans in it. all the reviews i have seen say that acer Bifrost runs the hottest of all variants and they assume it's from the unusual choice of fans. and you also know ambient room temps' effect everything. i almost got the acer version to replace my 3070 because it's almost as good in numbers but not in temps. mines stays around 46-54C depending on my room temps. so I'm def not getting it. and i did experiment with turning the power down on my 3070 using MSI AB it can go as low as 45% and i didn't notice any game performance loss but in the synthetic benchmarks like time spy etc. the numbers were lower, but it was averaging 32C at 45% power ha-ha.
