Am I correct in assuming that the thermal contact area (such as the core surface area) will have a big impact on a blocks C/W?
For example - say I mounted a waterblock on a CPU core, which dissipates 70 watts into the bp and thru careful measurements came up with a C/W value (say 0.24 C/W).
Now if I take this same setup and insert a 226 watt (Qmax) TEC/coldplate in between the CPU and waterblock, the input power to the Pelt will get added to the 70 watts of CPU heat producing somewhat over 300 total watts now going into the base of the waterblock.
If - I used the same 0.24 C/W as before and ran the numbers with the Pelt (0.24 C/W x 310 watts = 74.4 C + 25 C water temp) that would give an estimated hot side Pelt temp of 99.4 deg C! Not good...
Now I'm assuming this isn't really the case and that the much larger contact area between the Pelt hot side and waterblock will greatly decrease the waterblocks overall thermal resistance, resulting in a much lower C/W, right???
