With the GT you do not need to use any form of grease - the seal string is all that is required with you Phase Change setup. This is not the issue.
The CPUs you have a cold-bug plus you have an Expert MB with TCCD, so the combination will be more of a challenge.
You will need to work the Dram Strengths to help the TCCD modules on this MB which will also help you boot. Vdimm will aid in this too, again the Expert requires a bit more over the other MBs.
You can also try to set the Multi CPU registry setting as this boosts the temps of the CPU.
Temp reporting on the Expert is not accurate so -26C Idle is typical but prob. not true. Check your Evap heads based upon what it ran previously to esitmate the CPU temps or use a probe on the IHS.

Also, The CACJE will only clock up to 2.8 on phase which it used to clock up to 2.9 on water. You think the dielectric grease fom not having any is causing this? Thank you, Micah
