GTX 580 Heatsink on GTX 480? - Page 2

post #11 of 13
i have both heatsinks, and I dry fitted the 480 heatsink on my 580 without any issues.
Not sure if it would work the other way around or not.

Reference GTX580's cooling does not fit on reference GTX480.

 

The four pictures below show:-

And while OP is interested about fitting GTX580's cooling to GTX480, the chart below shows a GTX580 with reference cooling and a GTX580 fitted with GTX480's reference cooling.  It shows that the GTX580's vapour chamber is superior, at least for the GTX580 GPU.

They should of seaked out Scythe to build the fans for the Fermi GPUs or all Next Gen gpu's. As long as Scythe Oils the bearings before sending out because thats there only issue. They run dry and seize up.

Anyway a Scythe fan if they designed it to do so, could perform better at high rpm and quieter than the standard DELTA 1.8A 12V fans the reference cards used.

Right now I'm modding my gtx 470. There are numerous issues with the reference cooler. Firstly pressure on the core is lacking so i did a little modding and increased the pressure about 5lb ft possibly on the core. It yielded 10C drops alone by tightening it down better. Not only that but back metal piece has paint which reduces the thermal conductivity so the voltage regulators always run around 100C especially in game.

I removed the paint from the metal part and significantly reduced my memory/ voltage regulator temps by about 40C under load!

Does the card perform cooler with u cut a hole in the shroud on top of the cooler? and maybe mounted an exhaust fan on it? As long as u had more fans pulling hot air out of course...
