$30
I bought this excellent and compact CPU cooler back in April 2012, but it still works very well. Retail price at the time was around $60. Specs:
Noctua NH-C12P SE14 (https://noctua.at/en/nh-c12p-se14)
Comes with:
Note that currently, this specific cooler is only compatible with Intel CPUs on sockets LGA775,1366, 1156, 1155, 1151, 1150 and AMD CPUs on sockets AM2, AM3, AM3+ (I used it on a socket LGA1155). HOWEVER, if you have a more recent processor (LGA2011 or AM4 for instance), you can get an upgrade kit free of charge directly from Noctua (https://noctua.at/en/support/mounting-and-upgrade-kits)! Since you won't have the original receipt, you will just have to take a picture of the cooler next to a piece of paper with your name and the current date (see lthe ink, select your mounting kit and look for the form).
