Ending today, Newegg offers the refurbished Corsair Hydro Series H100i Liquid CPU Cooler, model no. CW-9060009-WW, for $62.99 with free shipping. That's $7 under last month's mention, the lowest total price we've seen, and a current low by $7.

A 30-day warranty applies, although it's unclear who backs it.
