I cannot agree with this.
What if I used silicone caulk as TIM? Its resistance to thermal transfer is very high. Very little heat energy is going to transfer to the heatsink. Rather, thermal energy is going to start moving in extraordinary proportions to the socket and eventually the motherboard as well. Its going to go where it can, due to the resistance encountered at the IHS. And since the socket is not a very suitable medium either, eventually the chip is going to die.
I do understand the Delta needs to be higher to achieve the same air temp at the heatsink, but using silicone as TIM would require exponential delta as compared to proper TIM.
Substitute poor TIM application for silicone, and I still think Delta would have to be exponentially higher in order to achieve the same air temp at the heatsink. I think OP's example, air temp would be...
I dont know, I'm confused myself now. Need time for this to sink in. Its wayyyyyyy past my bedtime.Edited by Baskt_Case - 3/31/13 at 3:35am
