Why is part of my 5970 at 96C and the test 60C???

A typical HD5970 having an idling temp of 60's C and a loading temp at around high 80's to low 90's C is not unusual.

For examples,

Regarding your specific setup, I see you have a HD5870 as well, which might sit closely to the HD5970 and contributes to not-so-desrirable circulation.

 

Additionally, a HD5970 exhausts heat via both ends.  Therefore, thermal management must be done carefully to establish intake and exhaust paths to avoid cross-pathing and hot air recirculation.

 

Other than these, you might also want to make sure the fan is functioning properly and with a good fan speed profile.  And removing the shroud to clean the dust in the heatsinks is also a good move.

my 5970 idles in the 40's and maxes out in the mid 60's with a custom profile on the stock cooler. anyways that 96C temp might be from your VRM's, which is acceptable for them
