Due to the complex power regulation Asus has fitted rather large heatsinks to the MOSFETS – as they get quite hot – and has followed up on the passive chipset cooling from the A8N-SLI Premium. However, as the board is now using a two part chipset, there are now two heatpipes, one from the main chipset and one from the SPP. Both terminate in the same copper radiator which sits on top of the rear-most MOSFETS.
The heatpipes are blocking access to certain parts of the motherboard and a graphics card with a large passive heatsink on the back might not work in the top slot. However, something like the Asus Extreme N7800 GT Dual – that’s the huge dual-chip 7800 GT card from Asus (review coming soon) – fits in the lower slot. This might sound odd, but as this is the primary x16 PCI Express slot it makes sense.
Another problem that might occur is that some very large CPU coolers would be hard to fit to the board, as there isn’t a lot of space between the heatpipes and the CPU socket. Generally this shouldn’t be a problem though, but something worth bearing in mind if you plan to use an oversized CPU cooler. For those wanting to use a passive heatsink or a watercooling kit on the A8N32-SLI Deluxe a fan is provided that has to be fitted to the heatsink where the heatpipes terminate. This is because it won’t be sufficiently cooled in such a system. This is easily installed by clipping it in place.
The rest of the board is up to Asus usual standards, although the layout gets crowded at times. Starting from the top working our way down, the power connectors are placed towards the top of the board with the 24-pin ATX connector located between the memory slots and the top IDE connector. The second IDE connector is angled at 90 degrees, something that can help keep cables tidy in your case if there is enough room in it.
There are only four SATA II connectors at the front of the board, but a further two are located at the rear, one internally and one externally. In terms of expansion slots there is a x4 PCI Express slot and three PCI slots as well as the two x16 PCI Express slots.
