i wanna know what of these are the best cooler (and with a nicely priced) for a custom ITX build, all fit, i only wanna a nice cooler, i liked the C7, my problem with him is this coler had no screw holes for another fan so this is bad since i wanna replace the stock cooler for a noctua or something, i will use Gelid GC Extreme as cooling paste, a recomendation?
