Welcome back Krow ~
Judging from the website, they should be good. A good source I have used several times is CTE: http://www.customthermoelectric.com/tecs_Qcmax.html They have Qmax 400W 62mm TEC which is good for quad core Intel CPUs.
So no performance gain? I thought higher thermal conductivity helps performance, since the pellets are what generate temperature difference, and ceramics plates are just there as an insulator and hold pellets together. This is also new to me. I need to do some research.
The plastic dip thing is interesting. Did you spray into the gap between cold and hot plate?
Nice polishing Looking forward to your full test~
Sorry about your work, my bad
It will work to some extent, especially with high speed fans. But the TEC hot side cooling is probably the most critical part of the system. My mindset is to go for the best cooling. People tried air coolers but later used water when they want better performance. I understand you do not want to use water because of the limitations. A:Dnyway, it will be a fun project. I am interested to see how the high rpm fans increase the performance.
Anandtech uses 340W source to measure the thermal conductance/resistance. But that does not mean it can cool 340W effectively. According to their result, D-15 has thermal resistance of 0.0944C/W, so 340W will put it 0.0944C/W x 340W = 32C above ambient temperature. That is 57C is your ambient is 25C.You are right there should be TIM between surfaces. Pressure is about 50-100psi. This is a very good guide on TEC mounting: http://www.customthermoelectric.com/TECmounting.html.
Freezer normally has smaller compressor as opposed to large compressor in air conditioner. The smaller compressor may not have enough cooling power to cool computer 24/7. The way freezer only need small compressor is because it is insulated and the stuff inside freezer does not generate heat like a computer. The compressor in air conditioner is more powerful, and it can cool an entire computer if you use a large compressor. You can search for "phase change chiller" to...
Using air cooler on TEC? It is possible but could be difficult. Generally under 100W CPU may be possible using large TEC and reduced TEC voltage. Achieving zero degree under full load is not quite realistic. 1. Because TEC is larger than CPU, and the surface of TEC is made of ceramic which is a poor heat conductor along its surface, slapping TEC on CPU will not work. There should be a copper cold plate between TEC cold side and CPU to compensate the size mismatch. The...
