Depends. Reference GTX 780 actually uses a vapor chamber, but as it has a single centrifugal fan configuration (blower), the heat is dispensed to the outside of your casing. Some other vapor chamber based coolers (e.g Sapphire Vapor-X) actually uses axial fans, and the hot air is dispensed and circulated back into your casing.

l read up that reference will blow the heat outside of the chassis by the card itself instead of dispense heat into the chassis thus reference usually hotter

You're correct. That's why reference cards (with blower style cooler) is very suitable for small (ITX) builds, since it does not heat up your casing. The hot air is expensed (almost entirely) outside of the casing.

It's actually harder to design a reference (blower) cooler, since manufacturer needs to balance between thermal and acoustic footprint. And there is only a single centrifugal fan, which usually blows out a lot of air, but also runs very loud. This is an area where Nvidia currently excels at, as you can see the Titan-style cooler used on reference 780 / 780 Ti / Titan / Titan Black is rather efficient compared to the horrible reference cooler used by AMD in its Hawaii based cards. And also the GK110 is a much more efficient chip (due to the Kepler microarchitecture) compared to Hawaii.

linus tech video showcase how to remove the titan cooler, l can see it is a quite complicated design by itself but seriously nvidia could have paint the cooler in all black for titan black instead of the original color theme
they better don carry this vapor chamber to 800 series

Cost. Manufacturer will hardly want to create a new design (even just black paintjob) just for one card, and for one that may actually sell the least.

Vapor chamber still remains one of the best cooling solution, especially for single fan blower. Why so skeptical over vapor chamber? Vapor-X and supposedly even Tri-X also uses vapor chamber technology.

the tri-x looks promising and tempting does it emit led?

LOL, tak ada LED. IINM, only the Toxic R9 280X got LED I think.

for a moment l thought tri-x emits green led like lightning

*raydenex 290 tri-x

that's just my NZXT hue led reflection on the card

no....!! l had been deceived, the led so lighting so strong!? even the gc itselfs shining, gonna buy few strips to play play

yes oh bro, when it hit 80'C , I can feel warm and hot rear side casing near the connector.

and i open side cover and touch the graphic card also hot.

non air-con room bro, I am using CM Storm Scout 2 casing. cables all hide behind motherboard side cover.

2 fans for front intake. 1 enermax t.b. vegas (adjustable fan speed) fan for exhaust.

i also open and touch before... not really hot la.... i got once using this 780 temp reach 91'C that is hot... Hahaha

80'C is just warm for me

im using a smaller casing than urs CM 690II 1x 120mm front + 1x 120mm back (exhaust) + 2x 120mm top (exhaust) dont seem hot to me LOL

All fan using Bitfenix LED 120mm

wah. 90'C

my 2pcs front intake fan is same with u too, Bitfenix Spectre LED 120mm x 2pcs

in your opinion, If I added 2 more fans as intake at the side cover, will it helps?

Yeah 90'C... i change some settings via that ASUS Software

But just curious 2x intake front? should be ok already....hmmm add 2 more shud be intake i think....

How many output (exhaust) fans do you have?

1 intake front, total 3 exhaust (1 back + 2 top)

but i reset the settings for card now constant 80-81'C

Usually, on stock settings, the GTX 780 will run at max 80 - 81C due to the GPU Boost 2.0 requirement (default temperature target).

hahaha i adjusted once i got it... then readjusted when i see the temperature

Me bole masuk ah? Been playing games with 780 Ti Classy, WCed...
