Hi Ersterhernd, I believe the T case reading would relate to the heatsink temps as it is in direct contact with the IHS or (Integrated Heat Spreader), some of the overclocker community are now removing the IHS to discard the Intel thermal paste between the actual core and IHS and re apply the thermal compound with a better quality product, Although the procedure doesn't look too complicated, I for one won't be resorting to it, as they claim massive temp drops. Googling the subject will lead you to youtube clips on the subject . I have much more investigating to do in trying to realize my ambitions in running the cube with a full power CPU and graphics in the cube, I have come to learn that there isn't enough room in the cube for the hardware and cooling devices and as Neil Hart pointed out that the cube's mesh in the lower panel is very restrictive and I may have to look at overcoming that. Please don't take this as criticism of your build or any other i7 cube as I think they are absolutely stunning in their detail but as I say, I want full power at any given time without any instability issues and finding that in the cube is a challenge which is costly enough without frying an expensive component such as the CPU and with the added graphics card and PSU. One thing I have learnt from the psu being inside the case is the increase in temps, even though the air exchange is quite large. Maybe even just a small fan to direct airflow onto the psu, not sure, but will keep searching. Rossi.
