Oh, OK thanks...
I appreciate your comment and thanks for looking.I did try a number of rated Peltiers i.e. higher amperage ones before settling for this one as this is indeed a comprise between the heat generated on one side against the cooling effect on the other.I found that there was no overall gain using a higher output device, just more heat.When I did settle on the 3A pump I again tested my setup as a straight heatsink & fan assembly compared to placing the peltier between and there was more cooling achieved when using the peltier.There just needs to be a heatsink and fan capable enough to dissipate the generated heat quickly enough.Thanks

Hi, there is no added vibration caused by this fan as the fan itself floats on rubber mounting points. I tested with various other fans before finding & using the one that I have used. Thank you.
