Hey bro, all is not lost. If you could give me some specs, I may be able to give you a BETTER solution to a single pelt setup. If you were to make a multi-pelt (2 or 4) setup, you MAY get BETTER temps than with one alone. I'm not talking about stacking. Mount them side by side in parallel, and you may see some pretty good temps. Here's the info I need:
1. Qmax (maximun heat transfer)
2. (delta)Tmax (maximum temp difference)
3. Imax (max current)
4. Vmax (max voltage)
While i'm making the calculations, you see if you could fit 2 or 4 pelts on your system. This may require modifying the coldplate.
If they are all the same exact pelts, you may be able to find them (or ones very similar) on my website. The cold side temps are listed there.
Here's the link. Note the parameters for the calculations though.
Oh, I'll need some rough estimates of your setup too. Here's the req's:
1. Processor
2. Temp of water
3. Quality of WCooler (eg: cheap, mid, hi-performance)
PS - I'm not making any promises
