If you are a fan of extreme air cooling then I am sure you have heard of the Prolimatech Megahalems. They are by far some of the best air coolers around. The only thing that really sets them back is their price, at $70. To help save you money Prolimatech has released a new Basic line which is currently made up of 4 coolers (B81/B65/B48/B45).
The Basic-81 remains much the same as the original as it has the same dimensions and number of fins. Instead of aluminum fins you are getting stainless steel ones, which obviously cuts down the price and will hinder your cooling just a little bit. You still have the 6 large copper heatpipes and copper base. That Basic-81 has a MSRP of $32.
The Basic-45 is a smaller compact cooler that uses 45 aluminum heatsink fins. It has two large 6mm copper heatpipes and a copper base. It ships without a fan so users will have to add their own. It is priced at only $14.
The Basic-48 is not released yet, but is just a little bit larger than the Basic-45. It has 48 aluminum fins and three nickel-plated copper heatpipes.
