Good fan, quality / price quite correct. Mounted on a config support "775" it cooled very well my core Intel E8400 (about 38-40 °) in any case well better now than the original fan that was in the process of giving up the ghost. Descriptive record very sleazy (images) done anyway attention to components around the radiator in the amount, to avoid damaging parts of the motherboard (but this is valid for any fan mounting Processor)! Thermal paste present on the radiator, so no need to purchase a syringe is something gained!
