Zalman Flex + Apache

[SubScape]

Hey guys, looking to upgrade my cooler from stock AMD, I have a pretty cheap mid tower case (fantastic for price, just lacking space) and I pretty much need a cooler sub 150-1mm in height, I was looking at pairing a Zalman CNPS10X Flex with an Apache black 120mm, I may get into overclocking in the near future as I honestly might as well, Anybody have any experience with the Zalman and/or apache and recommend/have any issues with it? Also would it I see much benefit in getting two fans in Push/pull? Regards

Thanks Wing, I did notice the performance of the vipers, but the fact it will severely clash with my colour scheme kind of put me off

You're probably right, I don't even have a side window, Temps seem good with the zalman + viper. As for the 4870x2, I'd have thought the gtx 460 would be an improvement?
