Motherboard: Intel 6321ESB Southbridge

Skulltrail 6321ESB Southbridge
Since the Skulltrail system is based on a workstation chipset, it also uses the corresponding workstation Southbridge. Intel's 6321ESB connects to the 5400 Northbridge either via four PCI-Express lanes or four ESI lanes. The following table compares the normal ICH9 Southbridge to the 6321ESB.
| Intel 6321ESB and ICH9 Southbridge Comparison | ||
|---|---|---|
| Southbridge | 6321ESB | ICH9 |
| Manufacturing Process | 90 nm | 90 nm |
| SATA-300 | 6 | 6 |
| USB 2.0 | 10 | 12 |
| IDE ATA-66/100 | 2 | 0 |
A floppy controller is provided through a third-party I/O-chip connected to the Southbridge through the PCI bus. Intel's D5400XS board does not provide a connector for a floppy drive, however. We did not have any trouble updating the board's BIOS with a bootable USB thumb drive.

So does anybody have a recommendation on a northbridge fan I can use?
preferably easy to install?( I really hate to take the motherboard out on that monster.)
