MSI releases 7900GT with passive cooling

[Darksaber]

MSI has just announced a new version of the GeForce 7900GT - the NX7900GT-VT2D256EZ. The card sports a passive cooler, using two heatpipes and a large cooler to get rid of the heat. The rest of the card is pretty much standard, as it runs at 450MHz on the core and 1320MHz on the memory. Using two of these in SLI should be possible, as the cooler does not take up a lot of space.

Hey dark or anyone out there, Im noticing alot of these hgih end cards are passive cooled, is it worth it other then the silence?

Nothing cools the ram though, that's the main problem here. It should come with copper ramsinks at least...

Actually since it's passive cooled, it should be alluminum ramsinks, since there isn't any airflow from fans to get rid of the excess heat that the copper conducts.

If its worth it or not depends on what kind of person you are. Personally i would much rather hear the slight sound of my fan humming away then to go without and get higher temps

I don't really know much about copper or aluminum ramsinks, all I know is that copper conducts heat more than aluminum. I guess you're right.

I have read a few review on these passive cool cards. Personally i rather they just pust something like a Zalman or Artic Cooling.

I don't care much about sound anyway. I usuall have my iPod on, or my surround sound, or a headset on for the comp. As long as the soun coming from the comp seems like the right sound that a fan should be making, or other parts, I'm fine with it. I actually like the noise better because I know that it's actually running.

one thing tough passive cooling is not for "overclokers"

Have these chips been modded to run cooler or is it just the normal card with very good heatsinks? Because it the chip runs cooler anyway you could buy one of these and chuck a fan on and it might oc further.

Edit: And how come MSI manage to passively cool a faster card than Asus with a smaller heatsink?

Copper absorbs away heat faster & Aluminum dissipates it faster

I don't really know much about copper or aluminum ramsinks, all I know is that copper conducts heat more than aluminum. I guess you're right.

Copper "ABSORBS-AWAY" heat faster than say, aluminum, but it comes with a "catch" on the reverse side:

Copper is denser, & thus, HOLDS ONTO HEAT LONGER than Aluminum does...

(Aluminum "sheds" heat faster than copper does in other words).



* Probably a great deal of the reason WHY you see 'combination' metals (usually Copper core for faster 'absorption of heat from the cpu core'/Aluminum fins for heat dissipation)

P.S.=> IIRC, that is the "physics" of it for heatsinks & metals used... apk
