Does anyone know where I can get some GOOD info on setting up two peltiers to cascade? I am thinking about trying this out but I would like more info before I shell out $40 for another peltier (I have one now, and I am not satisfy with it's "coldness")
My speakers are:
DanSpeak Multi 4.0, handmade from Denmark(2 X 6,5" Vifa mid/woofers, and ScanSpeak Revelator) bandwidth: 26Hz-25KHz
The End MK 3.1, aprox 2 X 180W, 900W PSU/120 000uF capacitors.A Kit from LC-Audio Technology(also from Denmark)
Pre Amp: Home made passive with an attenuator from LC-Audio Technology and an Elna line-out switch.
all internal cables pure silver/teflon.
xternal cables from AudioQuest
I'll try to update my site within a week or so, with both Hi-Fi-links, system-specs/pics(puter)and hopefully a completely new layout/design. I'll ask a friend of mine for some advice in the web-design part
Cascading peltiers for cpu cooling is extremely impractical. You have to remember that the second peltier has to move not only the heat of the CPU, but also the heat of the first peltier. This means it has to be about twice as large to get equal benefeit. It also means you'll need a twice as large heatsink. You're better off using two peltiers in parralel if you can.
SkrUbol sounded like he was making sense. I just acquired two 50watt TECs and was wondering how effective the "cascade" setup would be. You would end up with something that was less efficient than "parallel" TECs by virtue of the fact that the first TECs heat output must be absorbed into the second TEC, intead of straight into a heatsink or waterblock. The energy loss is in the conversion from TEC to TEC to Heatsink - not TEC to Heatsink. Add to that the fact that TECs are producing heat of their own just to operate. There must be some benefit to a cascade arrangement, I would bet it recovers quickly from heat spikes, and generally works better than a single TEC- although its less efficient. Hell if you've got one CPU and two TECs laying around, what else would you try but stacking them?

earlier Duckman send me a link to overclockers.au. They had a article on cascading and they needed 3 peltier. They used one peltier to cool the cpu and then stacked the other two to pump the heat from the first peltier and cpu. But I am beginning to think it is just best to get one good peltier from a reputable TEC manufracturer.
BTW, that site stated that most TEC are only 55% efficient. That's why you would need two peltier to pump the heat from one peltier and one cpu.
BTW, DUCKMAN, did you get your name from the cartoon Duckman? I loved that cartoon (and it's sick sense of humor to some, but not me).

Oh BTW, if I had two peltier I might try to use one peltier to cool my core and the second to cool my cache (I have a PIII). But I guess that wouldn't apply to your celeron, TNproud2b (and anyhow, you got your water cooling going anyways).
if I were to run two peltier in parallel, then woudln't the peltier cover the holes where I am suppose to screw the screw into the alpha to clamp the whole assembly together? From the pics I saw (that you posted), I see some new holes at the top of the cold plate .... can you explain (or tell me where there are more pics?).
