Hi After designing a quiet system i have recently noticed that the northbridge fan on my MSI K8N Neo4 Platinum motherboard is getting increasing noisy. I would like to swap it for a silent/quiet solution, i was thinking maybe the Zalman NB47J. However due to its location this becomes very difficult as it is located right next to the PCI express graphics card, with only limited clearance. What do you suggest? as i was considering trying to modify the zalman cooler or possible remove the exisiting fan and replace it with another, possibly larger fan mounted else where.
