UPDATE: I have managed to grab a bigger CPU cooler, DeepCool Assassins III to test out the difference ~ Holy Jesus, even at boot up, max CPU temp was at 60 compared to previously of 80+. In games/AIDA64 tests, my CPU temps dropped about 20C at max load. I think the H80i AIO is basically dying and it's been like this for a long time without me realizing it. EVGA cards are absolutely brilliant, thank you everyone! Hello all, I got my hands onto the EVGA 3080 FTW3 Ultra card. I installed it right away and I realised that my CPU temp raised from 80C to 100C after upgrading from a 1080TI (tested on Rainbow6). Things I have done: Flashed motherboard BIOS to latest version DDU removed graphics driver and reinstalled Re-tested CPU temps on old card (using same system) Results show so far that my CPU is significantly higher in temps running the 3080.

Your average and maximum woltage and wattage went up on your CPU. They didn't go up a lot, but they did go up. Make sure your that your Pump on your H80 is still working properly. Everything else in your computer dropped temperature between 3 and 6 degrees, only your CPU got hotter, so I would wonder if there is an issue with the pump or radiator. *Actually, I see your pump on the far right side, and the liquid temp did go up, but it says your pump is still running. By any chance did you bump the CPU block while installed, which may have caused a mount issue? That is strange that 90% of the items in your computer are running cooler while your CPU is getting hotter.

For that kind of a jump, something went wrong... Make sure your fans and pump are still plugged in. A couple degrees would make sense, because it's working to keep up with the GPU, but 20 degrees... That's not right, lol.
Did the CPU block get bumped at all? You may need to reapply thermal paste.

Hello all,
I got my hands onto the EVGA 3080 FTW3 Ultra card. I installed it right away and I realised that my CPU temp raised from 80C to 100C after upgrading from a 1080TI (tested on Rainbow6).
Based on your temps, your case's airflow is horrible. The GPU's heat into your case has doubled. Take your side panel off and set a small fan pointing at it. I'm sure you'll see both GPU and CPU temps plummet considerably. Also, update your GPU driver. I'm guessing you have a water loop with radiator on the exhaust -- poor choice, move it to an intake --- it matters. OOf, you're using a 120mm cooler on that CPU!? Just an inefficient config all the way around. Get a 240 AIO and front-mount the radiator at a minimum. I'd use a 280mm if you can fit 140s, or a 360 if you can fit it. 3080s create a lot of heat. Pictures of the case's interior showing fans would help. Do you have mesh or solid front? If solid, invest in a better airflow case.

I came from an ATX build with a 6700k and 1070 FTW3, to an ITX case with a 10700k and a 3060 ti. Before I had the GPU I was integrated graphics and had normal CPU temps, but definitely higher than my ATX case was. When I installed the GPU, even at idle the CPU temps went up about 5-10 degrees on average. I second the notion for airflow inside your case, and since you have not listed it, would be nice to know what case and fan setup you are rocking. I simply adjusted my fan curve to compensate. I would also go ahead and redo the thermal paste, and it would be nice to know what you are using for that as well. Since your CPU temps under load are already pretty high, I'd say those are the two most likely suspects, along with voltage and if you overclocked or use any auto settings in BIOS. May require some more under-volting.

Pretty normal for the temps on the CPU to go up after a GPU upgrade. Especially at 1440 or 4k. You removed a lot of your bottleneck allowing your CPU to work harder. Regardless though your temps were horrible before and they still are. You need better airflow, a better CPU cooler, or a better mount. Maybe multiple of those.

Hello all,
I got my hands onto the EVGA 3080 FTW3 Ultra card. I installed it right away and I realised that my CPU temp raised from 80C to 100C after upgrading from a 1080TI (tested on Rainbow6).
Things I have done:
Flashed motherboard BIOS to latest version
DDU removed graphics driver and reinstalled
Re-tested CPU temps on old card (using same system)
Results show so far that my CPU is significantly higher in temps running the 3080. Please see the attached screenshots on HWINFO
Specs:
i9-9900k, everything should be stock as I set bios to defaults
32GB RAM
CPU Cooler: Corsair H80i v2
Motherboard: Gigabyte Aorus Elite Z390
Due to max upload size limit, I have attached the screenshots of HWInfo here:
1080TI - https://i.imgur.com/UVoNCEK.jpg
3080 - https://i.imgur.com/gKKQ1nq.jpg
Can anyone provide me some advice on what I can test or do to hopefully fix this issue?
Thank you!
Alec
A 120mm watercooler for a 9900k? You must be nuts. That thing is maxed out, get a bigger one. If that rad is exhausting air out of the case, of course its going up, these series 3xxx ran much hotter so your internal case temps have gone up...

Thank everyone for your replies!
I have managed to grab a bigger CPU cooler, DeepCool Assassins III to test out the difference ~ Holy jesus, my CPU temps dropped about 20C at max load. I think the H80i AIO is basically dying and its been like this for a long time without me realizing.

That's good! The H80 isn't really made for a newer gaming rig, anyways, lol. What kind of case do you have? How many fans do you have in it? Might be able to get it even cooler.

your new GPU is pumping some heat into the case ... good to see a better AIO cooler on your CPU helps
Why is the back of case fan & the other two fans about where a CPU would be blowing forward ?
Might want to test as Intake & then Exhaust with the case's side cove fan position

You'd likely be a lot better off with the CPU cooler and rear fan as exhaust.

Amazing what a large CPU cooler can do eh? I was hitting around 80c on the stock fan for my i7700k a while back, after adding a dark rock slim with only one fan it dropped to the mid 50s When I switched to the i10700k the temps remained the same and I didn't need to buy a new cpu cooler as it fit the new one.

don't fight the natural direction of the airflow from the front of the case. Swap the CPU cooler and rear fan around. I'd also remove some HDD brackets if possible... or all of them. A Dremel can do more magic than merlin.

Turn your CPU and rear fans the other way, they're fighting the air flow from the front fans.

I'd have to disagree with everyone on the fan direction -- your cooler is an air cooler, no? You're doing precisely what you need to do for an air cooler -- You'll only gain CPU temps swapping it. There isn't flow in this case, only pressure. Lots of turbulence. Some forget the PSU is also an exit fan, albeit a small one.
Theory however is what it is, so based on where your case is sitting and the other variables at play, test results trump theory every time. Don't hesitate to try different configs. Or if you're happy enough and lazy like some of us, what ya got now is goodnuff
