GPU - Blower vs Dual Fan

[Hi P]

What are the advantages of the Dual Fan design over the Blower design in a non-overclock GPU?

 

Thank you

[xdeathshot20]

it really all depends on the case in question and how the airflow works.  generally dual fan or even triple fan cards tend to be better but if you are working in a small form factor case, then blower will probaly be better.  open or large enclosures will benefit from a dual fan design

Even if you dont overclock you usually get less noise and heat (on the gpu die) which may be nice if you ever plan to oc afterall or just for creature comfort.

 

Do keep in mind the airflow in your system though. In very constraint tiny cases with less than ideal airflow you may be better off with a blower regardless.

What about when stacking? talking about the RTX cards.

 

I'd like to avoid water cooling as much as I can, and I was reading about bad temps / throttling when stacking multiple 2xxx cards with dual fan design.

 

Would that be a good scenario for Blower?

stacking? I dont understand this word's use here.

 

tell us the case you will be using

Sorry is that the wrong term? (I speak Spanish)

 

I plan on buying the Cooler Master H500 along a single 2080 Ti, but I'd like to avoid water cooling whenever I get to buy a second one.

by stacking, you mean gong SLI or NVLink or whatever that's called? Stacking means putting one thing on top of the other, but graphics cards dont go like that.

 

If you go NVlink it's better to liquid cool the card between the CPU and the other card. Otherwise, dual fan or blower, it will lose a lot of cooling capacity

First would be how it effect the card, then the case or rest of the components. 

 

Open air dump heat in the case. Blowers do not. 

 

Noise is relative to the performance of the cooler and the case/fans effecting the cooling of it. 

 

My open air coolers can be just as noise except a higher pitch. Such as my strix. My acx coolers weren’t as bad though. 

 

I tend to use multiple cards so there is no using open air cards. 

 

Alao prefer the looks of reference or fe coolers. But if your system can handle it go open air.

Oh so you have Blower style GPUs?

do they perform the same as dual fans? (without O.C)

 

I don't mind the noise, but performance

Blower to get hot air out of the case you cannot afford to have in it.

 

Fans if you can afford to spin around hot air because you have sufficient intake and exhaust taking care of any issues this spun air may cause.

Depends on the card. My Keplers yes, perform identical and run the same temps. 

 

With my pascal with stock bios, no. The steps dont allow them to be the same. A single open air card can run cooler so it boosts up like normal. 1900/2000 area. Blower would boost to mid to high 1800’s. But with two cards it balances out. The open air cards can’t keep up with the heat. Even with fancy fans. 

 

But if you only need one card and it’s gonna be good limited, go open air.
