Thanks! Great tips for shielding thermistor cables. I found metal braided sleeving on eBay for less than $1/foot shipped (USA): https://www.ebay.com/itm/Tinned-Copper-Metal-Braided-Sleeving-1-8-1-4-1-2-3-4-1-1-25-1-5/142221053994?ssPageName=STRK%3AMEBIDX%3AIT&var=441288259663&_trksid=p2057872.m2749.l2649
Does the thermister cable metal shielding need to be grounded? I'll cover the metal shielding with plastic cable braid as well.
I'll also replace power module with the one you used and will twist the thermistor cables as suggested before shielding for good measure.
