NVIDIA RTX 3080 Cooler Design: RAM, CPU Cooler, & Case Fan Behavior Discussion
video description
NVidia said it's based on the game Control which has DLSS capability. Are Turing and Ampere both using DLSS? If so, and DLSS is improved on Ampere doesn't that imply that 1.9x number would be way high compared to normal games (no RTX)?
Whatever, I'll Google Techpowerup rtx3080 when the time is right and get a nice SUMMARY of game performance averaged over about 20 games. Best way to do it. Then zero in on things like relative RT and DLSS performance.

Can t wait to get more info on this, I ve been trying to figure out what case I might need to upgrade to by watching your case reviews. I ve been thinking of getting the white case you show early in the video, not the one you are talking the whole time with, and putting 2 x 140 mm fans, a exhaust fan and upgrading to water cooled cooler master cpu cooler and putting the radiator over the intake fans. But I don t know if I can do it with that case, so I was thinking of getting the nzxt h 510 elite and custom making a screen filter to replace the glass on the front. Not sure yet, gonna make decisions once I get my hands on the 3080. And if you want an image of what nvidia has been running to cool the gpu look on their website and you can see an image on the Rtx info streaming slide portion of a pc with the gpu in it. They have some kind of exhaust cpu cooler set up. Can t find that cooler available anywhere so maybe something new, not sure.

Yep, AMD stock coolers are not good enough for all cases(non extreme even), i live in a warm place(usually peaking at 38C) and had to buy an aftermarket option for my R5 3600, because cpu rendering in blender was exceeding 95C often, a few times i had to stop rendering because it got over 98 (I don't know why it didn't throttle at 95). Previously I had a R5 1600, which my wife is using now, and it never went over 93C overclocked and with the stock cooler that came with it... So maybe my new MoBo is abusing this CPU or Zen 2 is a very different beast. (I can tell they are pushed to their safe limits)
I've always chosen AMD even when they weren't this good, so I'm not a hater... I have intake and exahust fans on a fairly non obstructed case, so don't make assumptions on that end... And now let them salty fanboys come and unload their shit.

I'm almost expecting to see a video a day about different scenario and potential issues with thoses new cards, testing every configuration is clearly impossible (even if i think some prebuilt may be shipping with a stock cpu cooler). Kudos to nvidia to take a different approach for gpu cooling wondering if other will follow and if some issue appear especially with tower coolers some manufacture may try something alsa different to compensate (but it's clearly far fetch speculation at this point).
Anyways good luck to all of you for the massive amount of work incoming for the next month can't wait to see the data and what kind of number you will achievement in overcloking.

what is the temperature of the air pushed by the GPU directly in to the intake fan of the CPU cooler. I am wondering, is it better for the CPU cooler to have colder air from the front fans of the case or is it better to have hot air coming from the GPU fan directly in to intake fan of the CPU cooler. Also there is a mixing between the air that is pushed upwards from GPU to CPU with the air that is pushed from the front fans of the case towards CPU. I hope they will change that GPU fan to push downwards and back instead of pushing air towards CPU and RAM

you can always invert the cpu air cooler to take air from the the back of the case and have an exost in the front top, that way you would be adapting the airflow to match the gpu air flow what do you guys think about that? it would be the fan in the back of the case intake the air cooler flowing air towards the front of the case and then you can have either an exost fan in the top front or and exost fan in the front (it would be and look weird but I think it would be functional) am I right?

I think if you look at the MTBF of most fans used on GPUs, you will find its something like 6-7 years if run 24/7 365. I'm not saying being able to take apart a gpu isn't important, but its a weird thing you guys always harp on, especially when it comes to replacing a bad fan. Not condoning gluing them together like Nvidia did, but its a weird flex. Being an PC enthusiast site, I would assume most people are taking their cards apart to water cool them, or liquid metal them.

...perhaps...the 3000 series GPUs could be when vertical GPU positioning started making sense? Blowing hot air at PCIe slots should be better than blowing it straight at the RAM. Perhaps use the regular PCIe brackets behind the vertical GPU to mount an exhaust fan, to create a strong front to back airflow, helping suck out some of the hot air?

Interested to know how these cards will stack. Usually when stacking several GPU's for work/render machines, blower cards or watercooling has been prefereable to fans due to pushing most the heat out the back of the case. I wonder if this 'semi blower' cooler will be any good, or if it effectivly now makes the FE cards void for multi GPU machines.

Hey Steve, Looking at your Med. Modmats and I was wondering if you have any Plans to Update the GPU's Listed to Navi and Ampere or Maybe Keep this Version, but Come Out with a Brand New Design with The latest NVIDIA and Navi Designs?? Personal would Love a New Design since I already have the Original!
Great Work and Great Quality Merch!
