про контроллер пишут 120мм вентилятор даже направленный на него не справится...
I had a 120mm fan positioned to blow directly over the stock heatsink - even so, the heatsink was hot enough to burn my finger; probably around 70C or so.
Heatsink temps with the "quiet"* 50x50x10mm fan bodged on are around 50C as measured by my trusty Radio Shack IR thermometer. That's fine, but the fan blocks a PCIe slot that I'd like to use.
