Now that I have 2 8800GTX's in SLI I was wondering what the best cooling solution would be (bear in mind I have an Asus P5N32E SLI board with one of the PCI slots taken up with an X-Fi music card)?

I have seen the Thermalright HR-03 and was wondering if I could mount 2 of them and still keep the x-fi card?

Are there alternatives (apart from water)?

In theory two TR-HR03+ heatsinks can be mounted because there are two way to mount them with the heatsink hanging off bottom side of one card and off the top side of the other card. I don't know the dimensions and distances of your board, northbridge heatsink and CPU heatsink and finally the distance between the lower GTX and your X-Fi card. Without these values it's quite a big gamble.

Another option would be to test how "hot" your cards run with the stock heatsink. Mine was running too hot because a far too thick layer of thermal paste was used and while I don't think that I could have archived such drastic improvements without the HR03, I do believe that the stock heatsink with the proper amount of AS5 on the core had reduced my temperatures by 5 degrees or maybe even more.

I would also add a 120mm fan to the right side of the cards and open all rear case slots to improve airflow and possibly one more to the sidewall/window near the cards.

snip.

Thankyou for that well worded answer..Thankyou..I will try your suggestions first...failing that..I will consider going with a water cooling setup..such as the Zalman ZM-GWB8800 VGA waterblocks...they seem quite slim.

What temps do your cards run at idle and load? Just curious how effective those waterblocks are.

I have the gpu on it's own loop.

What about the zalman vf1000? It's cheaper and still good.

I see you have a Stacker case. Which one is it? If it's the 830 series, you can easily add 120mm fans on the side with the fan bracket.
