News Leadtek Readies GeForce RTX 3050 With Blower-Style Cooler

It reckons this design is "the best solution for servers and small cases." In addition, Leadtek has recycled a design used for other RX 30 cards and some GTX 16 series cards.

I'd be curious to see how well this design works compared to video cards that have the axial fan style, at least in cramped conditions where circulating the air in the case may not be the best idea.

Curious too. What are the pros and cons of axial vs. blower cooling for a video card?

Love the blower coolers.
GTX1080tiFE was one of the best.
They get the hot graphics air out of the case directly.
It seems entirely appropriate for a 3050 class card.

Axial fans can get heat off of the gpu better, but then you need good case ventilation to remove that heat out of the case.
Larger axial fans can run at lower rpm than a typical blower, resulting in quieter operation.

Larger axial fans can run at lower rpm than a typical blower, resulting in quieter operation.

Maybe in an open-bench setting. If low noise is a high priority, you should use a noise-dampening case with the strict minimum of ventilation holes and those are usually better at attenuating higher-pitched noises.

What are the pros and cons of axial vs. blower cooling for a video card?

Radial
+Excels in narrow/limited space, and stacking multiple gpus.
+The waste heat is pushed out the rear of the gpu, and not inside the PC.
-The design isn't very efficient.
For the best effect this type requires high(er) or maximum fan curves, but the noise may stop some users. The single fan needs to be able to push - maybe ram is a better word - cool air down the entire length of the gpu and out the back. The air pressure kind of drags across if the fan's rpm is low enough.


Axial
+Cooler design is more efficient than radial; can achieve better cooling at lower noise levels than radial.
-Doesn't do as well in narrow/limited space, nor stacking multiple gpus. These fans need a little more 'face space' than radial.
-Dumps its waste heat inside the PC, some of which the cpu cooler has to cope with too... with the exception of front mounted AIO/custom loop rad. For top mounted AIO or air cooler, the alternative is the user over-provisioning on cooler size, if possible.

Part of me wonders about this last point about axial fans. The issue I see is most heat sink fins are oriented towards the sides of the case, so most of the air gets channeled out that way. If the heat sink fins were oriented towards the front and back, I'd image that it would channel at least half the air out , but I also imagine it wouldn't be hard to make it so most of the air gets channeled towards the back.

And then there's NVIDIA's cooler design for the RTX 30 cards.

There aren't many cards out there with that orientation, but for the ones that do:
-some air blowback at the support bracket at the rear. The grille on the AIB models don't look, and probably aren't, as porous as the ones on the AMD Reference(none on 6000 series) and Nvidia FE models.
-turbulence between the fans on front to back style fins? Take a dual fan cooler, for example: <air | fan | air> ? <air | fan | air> ? < front chassis fan(s)
It looks less efficient than the one aimed at the sides. Then there's the PCIe slot guards - they impede airflow a little.
Some of the air likely gets recycled by the cooler too... IDK, too much speculation = 😵

And then there's NVIDIA's cooler design for the RTX 30 cards.

The cooler design for the 3070Ti FE and up was great. I wish the AIBs had gone with it, but nope... most are still taking a dump inside PCs.
