Here goes my first post... 
Running a Xeon W3502 oc'd to 2.88 and I'm experiencing temps in the 50-60deg C on my northbridge. My questions are:
1. What are safe temps for this NB? 
2. Has anyone seen or made any improvements to the cooling of this chip that I might try? 
The stock heatsink has a heatpipe over to the regulators, but the sink itself doesn't look like it would be too easy to install a fan on...
Any ideas?
