Both stack up very well but overall the Mine takes the lead, depending on what prices you can find them for. The Mine has a slightly larger and quieter 100mm fan. However, throw in a 120mm fan and it performs very well compared to the AC Freezer 7 Pro but, at $35.00 (Newegg U.S.) plus the cost of a decent 120mm fan you'd be in the price range of the higher performing 120mm products by Thermalright and Scythe.
If you can find a AC Freezer 7 Pro for under $25.00 (difficult to do), then that will give you the most bang for your buck. Otherwise the $35.00 for the Mine wins. Best price I could find on an in-stock AC Freezer 7 Pro is $30.00 at Newegg. Everyone else seems to be out of stock.
