I used cooler about 1 year, to buy this cooler is just waist of money.its cooling is too slow.the fan is spin slowly it does not cool to a large view means when we on the rotate mode it not give proper cooling .its service is good but cooling is too worst I seen ever.i suggest you to not buy this cooler its just waist of money.if just look good but cooling is too bad.when you buy a new a cooler try another cooler instead of it.
