I'm using an aluminum flash to try and bond a few peltiers too for the purpose of making a self cooling water radiator.
(Unfortunately for me the $3.99 flask is rounded and so not an ideal bonding surface thus I need the cement)
The thing is I don't know if the cement will be suitable for thermal transfer of heat from my water inside my flask to the peltier's cool side. Also, would it be a good idea to insulate my flask from room temperature, or would leaving the aluminum exposed help cool the water inside it? (colder then room temp vs hotter then room temp)

The peltier's and radiator are OUTSIDE my computer by the way so waste heat from the peltier's should have plenty of space to go. My plan is to have heat moved from inside my radiator to the outside air, while cooled down water flows into my cooling blocks.

What is a peltier?: (Bought mine for $4.00 each excluding shipping)

have you looked at this?
its available as both a spray aerosol and a paste, not sure if it helps but its what first came to mind when i read your post, if its too much you can try this.
You can get both at like napa/oreillys/walmart/etc

Even though the peltier cooler won't be sitting on top of your CPU, thereby mitigating this problem to a point, you should be careful with anything that has the potential to send water across that's cooler than ambient temperature, because that will produce condensation along every bit of the cooler that's outbound from the radiator, potentially including the CPU block.

Once the machine gets hot enough, that would balance out, I'd just be careful to make sure that the temperature from the CPU, even at idle, is enough to keep the liquid from getting below ambient temp in any part of the system.

I think I'm getting a better picture.
You plan on attaching a Peltier to the outside of a round flask (acting as a reservior) for a coolant loop.
The oatley product will not transfer heat, it is more of an insulator.

Good man. Condensation from the thermoelectric effect (Peltier) is a PITA for PCs, hence why you don't see them much in CPU cooler.
