Question Does bigger card = run cooler ?

[Kusky]

The Gigabyte 5070 WINDFORCE SFF vs ZOTAC GAMING GeForce RTX 5070 SOLID.

These two cards are at a good price right now in the UK, around £500. My main concern is sound for this upgrade. My old Gigabyte 2080 Gaming OC runs hot and loud.

I haven't found much info for those two specifically on thermals, so I've looked at their sizes. Both are triple fan design. Gigabyte is L=282 W=110 H=50 mm and Zotac is 304.4 x 115.8 x 41.6.

Would it be safe to assume, that the Gigabyte being SSF makes it run hotter and the Zotac being a bigger card will have a bigger heatsink and therefore run cooler and quieter?

it's a relative answer actually, if your case doesn't have optimal airflow, no matter how big the cooler is or the fans are, the card will end up running hot. If your case has optimal airflow, then yes it'll run cooler.

What is the make and model of your case?

Corsair - Crystal 460X is the case, although I have a front mounted radiator also. Covering 2/3 of the fans to cool the cpu. I understand that will restrict some cooling, but I cant move the radiator and I dont want a new case yet. Which is why atm I'm interested in gpu cooling capabilities, specifically does bigger = more efficient.

Radiator fans are part of case cooling just as much as case fans. If radiator is in front, it means pushing air in but that also means you need just as much airflow as exhaust.

The cooler doesn't particularly matter with regards to heat output as long as it's sufficient to cool the thermal load. A larger heatsink can dissipate heat better so you might gain a bit of efficiency and since your case has relatively terrible air flow would likely be a better choice. I'm fairly certain that getting a better case would do more for video card thermals than the difference in coolers of the ones you're considering will.

Also regarding the "SFF" branding in this case it's an nvidia thing and doesn't actually mean the card is particularly small: https://www.tomshardware.com/pc-com...nthusiast-class-gpu-into-your-mini-itx-system

Your Corsair - Crystal 460X doesn't look like a terrible case cooling wise, you could use a more aggresive fan profile if you want better case cooling.

It has closed front. That limits airflow considerably.
If getting a better case is not an option, then remove front glass panel.
This seems to be possible and would improve cooling/airflow tremendously.

Proper airflow also requires rear exhaust fan installed. Do you have it?
What is model name of cpu AIO cooler used?

Can you show a photo of your system with side panel removed?

All other things being equal then usually but it also depends on fan speed and cooler efficiency. A slightly smaller cooler made completely from copper will be better than a larger one made from aluminium for example. Fan quality also matters because a larger card with slower fans is quieter than a smaller one with faster fans even though thermally they might be around the same in performance.
