And the results…

Before mod:

After mod:

Load temperature of card drops from 74C to 56C.

That’s a 18C difference! For a $ 10 old cooler you can just purchase at the
back alley of Sim Lim Square shops, you can’t beat that! This mod works for all
6600 AGP or PCI Express.

Thanks to yaoyao for sharing his mod with us!
