Blower graphics card: does larger exhaust from removed DVI port change fan speed/temp?

[Bouowmx]

Considering GeForce RTX 2070: ZOTAC Blower and ASUS TURBO.

ZOTAC: Similar to Pascal reference design. ASUS: no DVI and wide gaps in grate.

I remember MSI releasing a Radeon RX Vega "Air Boost" model, but I cannot find any comparisons to reference model.

DVI needs to die on high-end cards already. Anyone who (for whatever reason) needs DVI but can afford these cards can afford a DP to DVI adaptor. As for how it impacts thermals, I'd wager that it is not a very large impact either way.

I would say the one without the DVI port has an advantage with the cooling.

Well, I assume that is what most users would guess. But I am looking if anyone has tested the difference.

I could not find anything.

I could live without it. DVI was always a terrible standard.

DVI is still very useful though, half the monitors still primarily use DVI-D. In terms of cooling, for sure the wider holes and open space helps cool the card better. If I had to take an educated guess I'd say about 1C degree difference purely off of that.

But again you have to take into account other factors as well like heatsink design, thickness, fins design, chamber design, cooler, etc...

How so? I still curse the horrible port design of HDMI. DP seems better, but I miss the screw in connectors of DVI.

Isn't VGA provided through DVI? You could do native/digital DVI through DP but you'd lose analogue connectivity via DVI which is still in broad use.

Yes, in DVI-I. But these use DVI-D which is digital only.

• DVI-I (integrated, combines digital and analog in the same connector; digital may be single or dual link)
• DVI-D (digital only, single link or dual link)
• DVI-A (analog only)

I have the ASUS TURBO and it's LOUD! The default driver setting has the fan (squirrel cage blower) running at an annoying speed. Also has an annoying RGB strip slanted across the top. And $1200 for a graphics card you'd (at least) think it would have the backside of the PCB covered. It doesn't.

As far as DVI, yeah it needs to die along with 1366x768 LCD panels.

Yes it absolutely does affect temperatures. NVidia no longer have DVI outputs on their GPUs starting with the GTX 1080 Ti for that purpose in fact. The removal of the DVI output allowed them to double the surface area of the heatsink resulting in a nice temperature decrease and higher clockspeeds. HardOCP did a comparison in their GTX 1080 Ti review and they found that the GTX 1080 Ti ran about 8c cooler when overclocked to the same settings than the original Titan XP which still had the DVI output.

Yes, in DVI-I. But these use DVI-D which is digital only.

Ah right, I just assumed they'd want to keep VGA backwards compatibility, but you're right Zotac uses DVI-D I dunno if that's standard on these cards or what. My bad.

Me and my monitor with its vga, dvi ,and hdmi would like to have a talk to you anti dvi people. My dvi does fine for 144hz and well the hdmi port on this thing is going towards a roku box lol. Geez i wonder if the hdmi port on this thing is 2.0 or not cause if i do a RTX upgrade in the future i may be ruined especially for 4k. Meh doesn't matter any upgrade for me would be a 60hz 1440p or 4k 60hz monitor with dp and hdmi if i get a RTX series card anyways.

That’s what I’ve been getting at though. Anyone who is purchasing a high end card isn’t running resolutions within the bandwidth limitations of dual link DVI (if they are sensible), where the highest resolution you can run without going below 60hz is 2560x1440.
