My feet prefer it cool too. Heat aggravates them, and leads to burning sometimes.
I read a physiology explanation about temperature sensation once. It says cold sensations supercede heat. This is why menthol in foot or body rubs works well for most PNers.
So if the heat sensing neurons are misfiring, stimulating the cold ones block the heat feeling.
Your mag seems okay. It should be working to help your circulation.
