Message: Subject: Ambient temperatures By: Ray (IP: 81.154.236.*) Written on: 24-04-2009 03:48 Are these observations correct? 0.2C ambient temperature drop = 1C object temperature drop. (Big heatsink, no fan.) E.G., 21.3C ambient = 29.7C 21.5C ambient = 30.7C Test object is a 2.5\" SATA -to-USB case running at 100% load with a lapped 150mm x 95mm x 15mm tall multi-finned 250gm aluminium heatsink resting on top & no thermal interface material. Adding a fan (any fan, any orientation) dramatically reduces the object temperature, of course. Thanks, Ray.

Measured CPU* temperature at ambient desktop 21C as 26.5C. Then I moved the PC onto the floor ... Measured CPU temperature at ambient floor 19C as 24.5C. I know people who have spent a fortune to get a reliable, consistent 2C drop in CPU temperature. Ray (Open door & window ... no-one\'s watching ... UK summer!) *SL7PP
