I've been looking into aftermarket coolers for my old build to get some better/quieter cooling performance and settled on these two for my 4870; the Akasa Vortexx Neo and the Arctic Cooling Accelero Twin Turbo Pro However I've read mixed reviews on the performance of both of these coolers. Some say the former is not sufficient to cool these cards and some say the latter results in the VRMs to get way too hot. Can someone who has experienced either of these give me a first hand account or can someone recommend a better cooler out there? Thanks in advance
