Just installed my MCP-310-49002-0N and ran through a very, very (non-scientific) test. Doing a Handbrake encode of The Waterboy (see, non-scientific, maybe something's wrong with my medulla oblongata ) prior to having the shroud installed, at the halfway point (about 15 minutes) the CPU temp (according to IPMI) was 93 C, and the fans were blowing at 2500 RPM. Idle temp prior to the shroud was about 72 - 74 C.
So, shroud installed - same test - at the halfway point, CPU temperature was 73 C and fans running at 2200 RPM. Shut down the test, wait five minutes, CPU temp had dropped to 59 C and fans were running at 1600 RPM, which seems to be my new idle temperature. Of course, this is far from time tested - I just wanted to report in on early results. So far, I'm a happy camper.
