Akasa 14 cm Viper High Performance S-Flow Fan, £9.95 Amazon/prime (£12.94 non prime)

Decent price at 9.95, however 12.94 is about their usual price.

Just a heads up to anyone thinking of buying these - they are not quiet - I have 3x the 12cm ones as intake on my corsair 780 currently running at 2/3 power and they are noticeably noisy in the room.
On the flip side though the air they move at this speed in incomparable with any fans I've owned before.

12cm = 83 CFM
14cm = 110 CFM

Keep them at <=50% and you should be good with far better air movement than any of their competitors.

noted! thanks for the review. Probably buying a dozen of these for my mining frames

I've got the 140mm and they shift some air, been very good fans. At high speeds they can sound loud but so do my £20 Noctua !

Good choice - using them currently to keep my case in check with 4xGPU's - going to have to move to an open build at some point though!
