a radiator very well made: for barely 50 was a cooling system equivalent to the towers 80 found in trade with an Intel Core i5 3570K OC 4.1 Ghz I reached 25 ° at rest and at play about 35-40 ° - Little less: - The radiator was damaged during transport: upper fins sank, but the heatsink is still usable, I have kept the product works wonderfully - Nothing indicates the presence of a driver already in the box, knowing that the installation was relatively difficult and the radiator requires a longer screw that found in the trade, I bought a Compatible screwdriver at the same time provides that and I find myself with 2 screwdrivers little use in conclusion:. a product with a perf / price ratio, a bit difficult to install, but the result is worth it !!
