We just had the thermal paste replaced on an Intel Core-i7 x 990 extreme edition chip with 12 cores but when it was booted up afterwards, instantly two of the cores reported overtemp (80 deg C) Upon opening the computer case and lifting off the air cooler, it was discovered that the air cooler copper die never made contact with the top of the chipset, thus the processor chip was run with essentially no cooling.
The thermal paste was replaced and the air cooler correctly seated and the system rebooted.
Now unfortunately the temperatures reported from the cores are discrepant and up to a 30 deg F difference was seen, core 1 is running 21 deg F average hotter than all other cores and core 2 is running cold.
I have a feeling that thermal damage has been done to the cores and this chip is basically worthless now, for normal runs.
It would be very helpful to me to get some feedback on this. In the past, while running under 100% computer load, I never saw the core temps differing by more than 4 deg F although they were running very warm, around 149 deg F to 152 deg F
Let this be a lesson to all. (sob)
One last question, are there any Core I7 x990 chips out there with all 12 cores unlocked? This chip had all 12 cores working at 3.468 Ghz guaranteed. We need a replacement chip as soon as possible.
