Prolimatech knows it makes some pretty powerful CPU coolers and it wants others to experience the coolers. What better way to do that than with a contest? Prolimatech is giving away two of its Black Megahalems coolers on Facebook, but you need to act fast because the contest ends on July 30th. All you need to do is head over to Prolimatech's Facebook page, "Like" the contest post, share the picture, and leave a comment on the post. That is all there is to it to try and win one of the Black Megahalems. If the giveaway post receives more than 1,000 likes, then Prolimatech will give away two more Black Megahalems. That could give you four chances to win, so head over to the Prolimatech Facebook page now!
