Do the cougar fans come with the fixation screws required, or do they need to be purchased separately ?
If so can you share the length/size of these screws ?

Thanks

No they dont have. You need +30mm screws. You need 1 spacer bolt or something or the cougars go too deep and fan will hit the frame.
Easy assembly but you need 2 screws & bolts for each fan. Maybe 4... i was lazy. Also my bolts were too long for top left corner. Anything longer than 40mm will hit 1 capacitor.

Thank you, just to clarify, will 30mm be insufficient, do i need more than 30mm screws

Also is anybody able to comment on the screw diameter and pitch required ? http://en.wikipedia.org/wiki/Unified_Thread_Standard

Would these screws, for example, work with a space nut ? http://www.pccasegear.com/index.php?main_page=product_info&cPath=83_388&products_id=25486

Antminer with heat sinks and Cougar fan applied.
32mm 6-32 UNC screws with a spacer bolt work perfectly

I am seeing about 300rpm slower fan speed, and about 3 degrees cooler at 400MHz

These work great: http://www.microcenter.com/product/354391/Plastic_Screw-In_Standoffs_For_Pre-tapped_PC_Case_50-Pack

I don't know if those specifically work but plastic motherboard standoffs work great for 120mm fans. BTW, love the little heatsinks.
