It's a shame it performs poorly out of the box. Mainly due to the fans? I wonder how the single fan configuration performs, these down-draft coolers are great for height restricted HTPC / SFF builds.
I've got a NH-C14 that matches the NH-D14 nearly step for step on a 3960X workstation at work. Wouldn't the Be Quiet TF cooler look nice with some Noctua NF-A14's or NF-P14's strapped on there? I bet those temps would drop a tad too.
Well most of these top down units are not realy for ultamate oc'ing there more for the budget mobo's that dont have mosfet heatsinks such as a lot of the budget FM2/+ mobos that can overclock, but you will still see in the manufactures notes that a top down heat sink is recommended.
