No, there are no specific rules on forming compound nouns. Hyphens are often used to reduce confusion in a sentence. For example, the compound noun 'wire clip' is perfectly acceptable as a compound noun, but for a term like 'plastic wire-clip', the hyphen makes it more readable. The compound word is correct with or without the hyphen.

six-pack or six pack
T-shirt or T shirt
great-grandmother or great grandmother
half-sister or half sister
sixty-six or sixty six
warm-up or warm up
