I'm really keen to buy a thermonamic TEC with T200 CuSn solder, much better thermal conductivity than standard T100 BiSn solder, also I want one with Aluminium Nitride Ceramic as opposed to the standard Aluminium Oxide, once again much higher thermal conductivity, I got quoted about USD$150+shipping IIRC for one specced like that, USD$40+shipping for a standard one, not sure how much better it would be but the thermal conductivity increase alone would mean you can basically turn your TEC off and it will still transfer the heat from the cold plate through to the water block very well. Now this is speccing the TEC up from thermonamics standard, its about a 4x increase in thermal conductivity of 2 of the most important components in the make up of a TEC, now imagine what no name fake stuff the cheapo TECs are using instead of aluminium oxide that thermonamic uses standard, I can imagine it isn't specified on any data sheet and hasn't been selected for optimal performance.
Judging from how bad my little cheapo 12715 is struggling to transfer the heat when my CPU is at 100% load when heavily OC'd I'd imagine it is more likely that my cheapo TEC is not up to snuff more so than my Thermal Grizzly Kryonaut TIM and my water block mount. Baring in mind, I bought a 12715 based off of my calculations from customthermos 12715 data sheet, so I can guarantee it won't perform as well as customthermos otherwise I'd be able to hold far better temps than I can at load if my cheapo TEC matched the data sheet of customthermos. So I think it is worth spending a bit more coin, maybe not $150 for thermonamics specced up option but certainly about $40/TEC is worth it in terms of overall result, efficiency, delta, longevity, power consumption etc. I'd say the only data that cheapo TEC's actually have on their TEC's is Umax and Imax, the Qmax is already derated from customthermos for my 12715, 132w qmax vs 141w qmax, so delta might not be as good either. I am quite happy I bought this Kryotherm TEC, I just wish I could find something less power hungry with enough qmax in the 40x35mm size that I got this one. Now to find out how well it performs, I haven't got access to a data sheet for this one either, its 111 couples, 13.7v and 23.1amps, so I've derated a customthermo 245w qmax 26amp 15.2v TEC and hope it is similar to that even though the couple count is different and the imax and umax is about 10% more.
Overall though, I'd say quality water blocks and quality TEC's will make all the difference between being extremely effective and just being good enough.
If I had the funds to buy ultrasonics 62mm TEC block that another user just bought I'd probably spend the money on one of those crazy expensive specced up thermonamic units and his block and just run it as a direct die on every PC I buy for the next decade haha.
