Lowered the temperature considerably on my old 6600GT AGP!
From ~ 55 ° C in idle to 37 ° C. Load went from 95 ° C to 60 ° C.
But most importantly, so lowered the volume on your computer significantly, especially when the standard fan had a small crack that created instability and vibrations.
The only thing annoying is that accompanying heat sinks to the memories must be cut some to fit under the radiator when the memories sitting so close to the GPU on this card.
There are pictures of how another made here:
Now I run the card overclocked and cooler at 5V with the included adapter, the card idlar 39 ° C and is located at 65 ° C load.
I run, however, the version with the black fan without LED, but this teaches gonna work just as well.
