GTX 780 Ti reviews

lol

Yeah, I know. Let em have it.

In principle air is not getting out of this part , it should be
pulled inside the card from this side .

Incorrect. The fan sucks air in through the center and expels it in all directions. That includes the back of the card.

I thought air was also sucked from this side of the card and pushed to the exhaust that is at the rear of the PC, if it effictively also blown from this side then all i said is even more relevant as this side has forcibly lower resistance to flux pressure than the other side , most of the heat is released inside the case.

Here I found the card's picture while operating, which better explains my point :

Infraction issued for thread crapping. 3-day automatic vacation for points accumulation.

Seems legit.

Probably why it's so fast, afterburners.

Can someone confirm whether that blows or sucks or both?
Is this a case of taking advantage of the fact that most reviewers run an open bench :sneaky:

Both. I read in a review that something like 5% of expelled air goes back into the case. I'll see if I can find it.

Seems some guys are REALLY reaching to discredit the best reference shroud ever designed - with objective measurements showing excellent cooling and acoustic performance. Gotta wonder about the real intentions here.

I don't think anyone's buying it. Sorry.

It wouldnt matter if cards were 30-50W but here we re
speaking of 200-250W and if it s the case (pun intended)
i m quite amazed at how amateurish and clueless the reviewers
can be...

The intention is to discuss the design choice of a manufacturer,
namely the technical caracteristics of the card in this topic.

Is that irrelevant to the thread.?.

5%? Lol. Better find that source...

I bet in reality it's something like half.

Stop Off topic, this is not 7990 thread. We are talking about <300W GPUs that don't need that kind of cooler

5%? Lol. Better find that source...

More than a half. The amount of air that goes to one side is proportional to the flow resistance of that side, compared to the opposite side.
So if this side is 1/3 lenght, of the back-end. 2/3 of air goes from the front end, and 1/3 of the rear end.

Taking fan placement and rotation into account (opposite to thinking of it as high pressure source) the amount of air will be split around to 50/50, with a bit more air going though the path with lower air resistance.

The heck is this crap? I hate using the "thread crapping" card but seriously, everything on this page is garbage. Trying to discredit the Titan reference blower design - I don't know who anyone's trying to kid here about the Titan shroud because it's been tested by thousands of websites with objective data showing it to be the best designed blower cooler on the market. Let's not try to deceive anyone here, facts are facts, nobody is buying it.

Just. Stop doing what you're doing. Because the cooler has been tested for nearly a year and the results have been out forever.

this isn't about how well it works though

it's about how it works (ie not a shroud)

It expels all of the air out of the rear, it's quite obvious if you've actually used it. Have you used it? The vast majority of the air can be felt forcibly being rushed out of the back, just like any other blower design. It isn't expelling air inside the case to an appreciable extent, maybe 1%, if that. In fact, I remember putting my hand near the area in the front and no air can be felt being expelled from that area. Only from the rear, just like any blower.

Is it exhausting hot air into the case or not?
Just trying to get a handle on how it works
Thank you, only 1% eh?

 

[96Firebird]

Even if air is escaping through the vent closer to the fan (I'd have to see what the cooler looks like), that air is only going to be as warm as the wattage of the components under the heatsink there. And guess what, I'm willing to bet the air will be close to ambient.

 

[blackened23]

I have no idea if it's 1% or 5%. But it isn't expelling hot air from there - How do you measure a percentage of hot air dissipated? Anyone that has used it, and I know a bunch of people here have used it - there is no appreciable amount of hot air being expelled from the front area of the card inside the case. It's all about air flow direction - the air is being expelled from the rear just like any blower design.

I'm sorry, anyone stating that 50% of the hot air is being expelled inside of the case is misinformed. That clearly isn't the case - it's quite obvious if you actually use it and put your hand against the front of the card. The majority of the air is expelled from the rear, as it should be.

Who has one? Fire up a game and stick your hand next to that end of a reference card.

Don't do that, it might explode and take your hand with it.



Not having this thread crapping nonsense.

Then explain what is blocking air to go through front heatisnk

Purolator is holding mine hostage.. it went from LA to Vancouver over the course of 4 days. Based on where I live, they shipped it about 10% further away from me.

 

[Keysplayr]

I have to laugh at those saying half the cards heat comes out of the back. Does anyone happen to notice where the fan sits and the difference in the amount of heat sink real estate that sits before and after the fan?
Let's start with that and we will work our way up to discussing why any of you were compelled to say that 50% or greater of heat comes out the rear of the shroud.

 

[blackened23]

Yeah. It's hilarious. Whats even better is the concept of direction of air flow. I know that concept is lost to some folks, apparently. Hint: direction of air flow = TOWARDS THE REAR OF THE CARD.

Proof is overrated when rumors and deception can be used instead, yeah? So which reputable website is showing "50% of hot air being expelled back into the case" Oh yeah. None.

 

[Gloomy]

For what it's worth, I said nothing about heat, just air. I don't know what fraction of the heat is expelled into the case, and I'm not going to take a guess either.

But it's obvious that the card expels more than "1%" (lol) of the airflow back into the case.
