Newegg offers the Corsair Hydro Series H100i Liquid CPU Cooler, model no. CW-9060009-WW, for $99.99. This $20 mail-in rebate cuts it to $79.99. With free shipping, that's $17 under the lowest total price we could find, although we saw it for $10 less in January. (For further comparison, we saw a refurb for $22 less four weeks ago.) This liquid cooler allows you to monitor coolant temperature and adjust cooling performance directly from your desktop. It features two 120mm fans and a mounting kit. Deal ends November 20.
