Went from a 226 to 156 pelt and...
My temps have never been better. I have two heatercores , shroads , 120's. Im using the Becooling PSU.
I dont know - it seems crazy. I can run 2300 Mhz @ 1.7v @ -5C idle 5 C load.
I can also run 2524 Mhz @ 1.85 @ 10C idle and 14 C load.
This is after running for a good 2-3 hours too. Franky Im shocked. I would have never thought to try this either if the 226 pelt wire handn't have broken off.
Just incase someone else out there is stumped .

doc said:Nunez1980, I think you need a reminder of what efficiency is. It has more to do with the ratio of heat pumped vs power input than what is the max heat pumping. At lower than max power input you do get less than max heat pumping but you can get more watts of heat pumped per watt input. So yes the efficiency does increase if you run TECs at less than max, but the trade off is that you can not pump the max rated amount of heat.

doc, I understand that, but as long as you can handle the heat load, running the tec a full volt is better than at less volts, thats just my point
If you can't them its just better to get a lower wattage tec, than the higher one

I take exception to that statement. My experimentation has shown that a tec operating at 70~80 of maximum rated voltage gives a higher ratio of cooling to heating. So running a tec at full voltage in order to achieve xxx cooling will have a hotter 'hot side' than a higher rated tec running at 70~80% or rated max voltage achieving the same cooling.
