Reference VS EVGA ACX2.0 GTX 980Ti

 

Need answer fast Im about to buy.

 

I will be running SLI and my case airflow is meh [Corsair 750d]

 

Reference or ACX2.0 and please add opinion. Thanks

If your airflow is terrible, reference designs will fare better.

SLI go with two refernce cards

Reference

[SeanBond]

Why not both? If you don't care about uniform looks I think that bottom reference card with top acx would provide the best temps.

[m_tieu]

Reference. I have the ACX cooler on my 780ti and the top card runs a lot hotter due to the open design.

[thekeemo]

top reference bottom acx

[sgloux3470]

Either is fine.  It's either run at 80 degrees with a better cooler or run 80 degrees with a blower cooler.  Not a big difference either way.

Reference design for SLI matters more with 3-4 card setups.

top reference bottom acx

 

This. If you have the top of ACX, your bottom card just gets hotter. You could go with bottom reference and top G10+H55 @Faceman spoiler

Wouldn't the bottom air get the cool air first? This would force the heated air out the back, with what is left over the top acx card would push the heat out the top. Reverse that and the heat goes up into the reference card, what am I missing?

The fans on the top card would blow hot air all over the bottom card.

fuck reference

Oh well okay, thought the air would go upward. I am no expert on sli.

You don't need to know about SLI in order to understand physics. As long as you understand the physics of air and the capabilities of fans, you should be able to deduce what would be the proper solution—therefore, I wouldn't deny immediately what you're saying just because you're not an "expert" on SLI.

you are right, you dont have to be an expert. The fans suck cool air to the card. Not blowing hot air away. But in SLI the problem is there is not enough cool air that can come to the upper card. The fans just suck the hot ambient air of the lower card.

ACX. Got a reference 980 and it was the worst mistake ever; #nevaagain

Not sure why you sound upset with me over something silly.

And yes, they suck air towards the card, the reference cards push all the air out the back. How could the top card suck in heat if the bottom card has already pushed out all the heat? Then the heat from non reference cards should be going upwards, the same direction the card's fans and the case's fans are blowing. I really must be retarded because I am not understanding physics right now I guess.

I was simply explaining why you shouldn't feel like your opinion is invalid because you don't feel you're an expert in SLI. I wasn't intending to hurt your feelings in any way and didn't intend to sound upset at you.

Don't worry about me, im not upset. But I would like a good explanation of how I am wrong. So what was wrong with my last explanation?

Air gets hotter in ambient of hot objects. the lower card is increasing the ambient temperatur of the air beetween the both cards because of thermal radiation. And heat is allways travelling upwards.

 

But consider a custom waterloop as answer to your problems.

You are only helping my point. Regardless of the sli config you are going to have higher ambient temps because there are two hot pieces of metal in one space. Now say you have a non reference card, all that heat that card generates is going upwards into the top card. But if it was reference like I said the great majority will be pushed out the back instead of spread in the case. This is why reference cards are usually best for sli configs.

i never said you were wrong ;D

uh....buh...huh. The way this conversation was going I thought I was being disagreed with and I couldn't understand why.

in my first post i allready wrote that you are right ^^

Woops, I was thinking I was talking to the same person who posted what arnavvr. Lol I have been arguing with myself.
