My chipset fan seems to be going on my Asus A8N-SLI Deluxe and I need a replacement. Trouble is it has be be relatively low-profile (no more than the stock one) due to the video card, otherwise I'd use the spare Zalman ZM-NB32K I have. The Akasa blue LED fan at Scan looks too tall at 20mm. Anyone know a good Northbridge HSF that would fit the bill?
