graphics card heat dissipation numbers

[rehpyc]

It'd be nice for people looking into buying different cards, such as myself, to have one thread to see the types of heat dissipation required for each card at full load.

How much heat would a 8800 GTS 512mb at stock produce, and heavily overclocked?

How much heat would a 8800 GTX at stock produce, and heavily overclocked?

Feel free to add other graphics cards you know the numbers for.

What defines "heavily overclocked"?

A 8800gts 512 class card consumes around 100-150w under full load of course not all of that will be the gpu (split among memory, vregs and so on) and some of that heat will be dissipated by the board and other components.

a 8800ultra is about 70watts more for around 170-220w

This is all at stock clocks btw

I'll calculate the electrical draw of the card and figure it's about that in heat. Very rough, but it's always worked before :shrug:

A calorimetric method using 2 waterblocks leads to (8800GTX@ stock clock/voltage) :

Idle
- GPU only: 40.1 W
- GPU + mem + I/O: 53.1 W
3Dmark 2006 - Canyon Flight (loop)
- GPU only: 79.9 W
- GPU + mem + I/O: 96.8 W
3Dmark 2001 - Nature (loop)
- GPU only: 89.5 W
- GPU + mem + I/O: 108.0 W
ATI Tool - Furycube
- GPU only: 94.3 W
- GPU + mem + I/O: 117.1 W

There are points in 06-3dmark that push the card harder than the ati-tools scan for artificacts
