Re: 8800 GT and Zalman VF900-Cu
Whoa my GTX idles higher then that even with fan at 100%...
54celcius to be exact and can go much much higher when playing a game.
Maybe I should do the same?
Was this easy/plug and play? Where can I buy those parts/maybe better ones? Thanks! |

I needed four additional heat sinks for the mosfets, but you can get them from Zalman, too. Zalman's quality is excellent.

Stock 8800GTS cooler | 
VF1000+ZM-RHS88 | 
Highly overclocked settings | |

You have to use the Zalman ZM-RHS88 and VF1000 set. I have it on my 8800GTS 640 and it idles at 52C and loads at 72C while overclocked. That's on silent fan settings. On 100% fan, the VF1000+ZM-RHS88 barely makes 64C at full load.
As for the pictures, they were a before/after screenshot. Please note that the stock cooler is at 75% duty cycle and not the normal 60% - otherwise it'll show around 90C at load. |

Worlds apart in terms of cooling performance. If the VF900 is lagging behind that badly, a GTS/GTX stock cooler would probably better than the VF900. You have to remember that the VF900 was designed for GPUs with small die size, the GTS/GTX's die size are a lot larger than previous generation GPUs.
Don't get me wrong, I love the VF900. I had it on my 6800GT and it was amazing. It's just not the right cooler for the GTS/GTX.
Note that the X1950XTX loaded at around the same temp as my 8800GTS with its stock cooler (page 4).
EDIT: Besides, the VF900 won't physically fit on the GTS/GTX. The mounting holes are farther apart than what the VF900 could reach. |

You have to remember that the VF900 was designed for GPUs with small die size, the GTS/GTX's die size are a lot larger than previous generation GPUs. Because it won't work on an ATI card doesn't mean that it won't work and work effectively on the 800 GTS series. A tad disingenuous by the author, I think.

That's a legitimate reason.

For what it's worth, the Zalman's "8-pack" heatsink package is not what you might expect. The VF900 does indeed come with 8 identical memory heatsinks of the kind pictured here. But the heatsink package comes with 4 of those, and 4 others that have the same footprint but are much taller. Not that that's an issue for the MOSFET's but just an FYI -- this is not a replacement for the included heatsink set. I also got (from NCIX) the 4-pack of Swiftech MC21 aluminum heatsinks which might be a better fit on some of the chips. That gives me more than enough to play around with on the MOSFET's. All of them come with thermal tape pre-attached.
