Out of stock on the Yates at Jab for several months now. Not even on their site anymore. Have them at Tekgems for $11 single units...2or more $7....5 or more $5. Nexus are $16 at Jab. As I have read, Nexus "cherry picks" their Yates for least amt of bearing/motor hum/noise. I have never used a Yate (besides my rebadged Nexus's), but imo I would go as operandi said on the HS (or xp120) and get a Nexus. Thats just me. With the right case airflow setup & install, the Nexus @~1000rpm is more than adequate to cool any oc'd CPU paired with the SI/XP 120. You can get the HS and fan from the same etailer as well.
