With premium (>$50) CPU air-cooler market getting hammered by low-cost all-in-one liquid cooling solutions, premium CPU cooler manufacturers such as Prolimatech are feeling the heat. The company launched its first line of low-cost CPU air-coolers under the Basic series. The coolers come in five sizes, and feature no-frills designs that make use of aluminium and copper. The series includes the Megahalems Basic, which was launched this January, which is now rehashed as the Basic 84. The series starts off with the Basic 45. Measuring 100 mm x 55 mm x 125 mm (LxWxH), it weighs 288 g, and features a simple aluminium fin tower with a pair of 6 mm copper heat pipes. A 92 mm PWM-controlled fan is included, which spins between 1000~2000 RPM.
Next up, is the Basic 48, which is a step up over Basic 45. It has the same exact dimensions and included fan, but weighs a higher 309 g due to a third nickel-plated copper heat-pipe. A notch above the Basic 45 and Basic 48 is the Basic 65. Measuring 130 mm x 50 mm x 148 mm (LxWxH), it features an average-sized aluminium fin tower to which heat is fed by three 6 mm-thick heat-pipes, and ventilated by a 120 mm PWM-controlled spinner that revs between 600 and 1,600 RPM. The Basic 68 is its premium twin, which features four heat-pipes.
Lastly, there's the Basic 81, which as we mentioned earlier, is a re-brand of the Megahalems Basic. It's shaped exactly like Prolimatech's iconic cooler, measuring 130 mm x 75 mm x 158 mm (LxWxH), weighing 748 g. It uses six 6 mm-thick nickel-plated copper heat-pipes to distribute heat between two parallel aluminium fin stacks. The included 120 mm PWM-controlled fan spins between 600 and 1,600 RPM. Prolimatech didn't announce pricing or availability details.

Basic 81 seems like it will be a failure if it's stainless steel (much less heat conductivity): Aluminum is about 150 to 200W/(m*K)
and stainless steel is around 10 to 34W/(m*K)
... hopefully people don't fall for it and buy them thinking they are Megahalems. I bet a lot of Ebay scammers will sell it as Megahalems. There's already the Alpenföhn Brocken 2 (~£40) which looks sort of like a copy, but without the etching on the top of the fin stack. If the Basic 81 turns out to be Aluminum (just without polish / coating or the same build quality, for product segmentation) instead of Stainless steel then it'd be a contender. I'm pretty sure people wouldn't mind a few minutes of fine grit sandpaper / buffing wheel action on a machined base if it comes at Thermalright Macho pricing.
From the product lineup it only seems that the Basic 68 (120mm fan) is worth looking at , it comes with PWM 120mm Double-Ball Bearing fan and packs four 6mm heatpipes and works on LGA2011 (Basic 65 doesn't list LGA2011). The other difference seems to be that the Basic 65 is shorter by ~10mm and loses a heatpipe (which would make it about as effective as a Hyper 212 Evo). The basic 45/48 has a 92mm fan.
As far as cost goes OCUK has preliminary pricing:
Basic 45 = £17.99 , 125mm high ... pitiful 2 exposed copper heatpipes ...
Basic 48 = £21.95 , 125mm high ... 3x 6mm heatpipe ...
Basic 65 = £27.95 , 148mm high ... 3x6mm heatpipe ...
Basic 68 = £31.99 , 158mm high ...4x6mm heatpipe ...
Basic 81 = £34.99 , 158mm high ... 6x6mm heatpipe
Compared to: Prolimatech Lynx £22.99 3x heatpipe 120mm fan (so Basic 65 is overpriced) , Panther £32.99 4x heatpipe 120mm fan (Basic 68 is about right)
Can these compete with the likes of the revised (i.e. nickel plated) Thermalright True Spirit 120m , Macho120, Macho, and Thermalright True Spirit 140 (running ~$30-40 and £25-30)? I don't know but doubt it...
At the lowend there's the Raijintek Aidos with 4 x 6mm heatpipes + 92mm fan as well as Raijintek Themis (120mm , three 8mm heatpipe) going for ~£20 and while they're cheap & not made to the same standards , they provide respectable performance.
As a benchmark the Cooler Master Hyper 212 Evo that is so damn popular and comes with a lame Cooler Master fan runs ~$20-30 has 4 copper heatpipes with no nickel plating. The successor Hyper 212X will be similar , with a slight fan improvement and tweaking to airflow across the top of the heatsink plate.Edited by AlphaC - 11/11/13 at 9:37am
