Cooler Master's MasterLiquid ML240L RGB All-in-One (AIO) CPU cooler has been featured several times before, when it sold for about $67. This time, however, a mail-in rebate has brought the final price down to just $41.99, making this cooler the best deal yet.

Newegg has it for $74.99 (down from $79.99). Apply coupon code 93XQU69 at checkout to save $8 off the sale price.

So what's the catch' this is not the new V2 revision, which sports an upgraded dual-chamber pump and a different fan; the V2 model is currently $79.99 on Amazon (on sale from $84.99), so that's almost double.

Nevertheless, despite its goofy name (a name that Burgermeister Meisterburger might come up with if he got a job in Cooler Master's marketing department), the original Cooler MasterLiquid ML240L RGB is a competent cooler; our friends at Tom's Hardware reviewed the ML240L RGB several years ago and praised it for offering "great performance" at a "very attractive price" without considering discounts or rebates.

As the name suggests, this sealed cooler utilizes a 240mm radiator and is fitted with two 120mm fans. It also utilizes a dual-chamber pump to isolate the heated coolant for improved performance. In addition, being an AIO cooler, it requires no maintenance.

Simply put, you will be hard pressed to find a 240mm AIO cooler for the same price after rebates. The EVGA CLC 240, one of the best CPU coolers in the realm of affordable liquid coolers, is more than double the price at $88.99 on Amazon (on sale from $119.99).
