Update for my results



results from VDO on before and after, system setting 3570K@4.5GHz, 1.3Vidle), 1.296Vload | RAM 2666C11, 1.65V | Room temp ~37ºC

Before remove the IHS or intel stock TIM


about Subzero sense #1 measure at heatpipe and #2 measure at base, this can help to checking for about heat transfer from Die to IHS
if it heating up that mean heat from CPU die can more transfer to IHS



from above seem average different about 10ºC for before and after

more testing with different clock and lower Vcore

3.8GHz


4.0GHz


4.5GHz


4.7GHz - this is max MHz of this chip can do before remove IHS with this cooler


finally after replacing TIM to Gelid GC-Extreme temperature lessen ~10ºC and it can get more MHz ~200MHz from 4.7GHz to 4.9GHz
now it can stress at 4.9GHz but before can't do over 1 minute and temp will jump to 100ºC in 10sec !
