| 744641 | 2009-02-03 19:29:00 | At the moment i am trying to build myself a laptop stand with cooling fans. As you know i love those huge giant fans that comes with some high end pc towers. I was trying to look for those big fans on trademe and some sites in NZ but i was very disappointed. on trademe the biggest they sell is only 140mm, and in some other site the biggest is 200mm (it is called big boy something something), and it is very urgly! :dogeye: aren't there bigger ones available? like 10 inch (250mm) or something like that? aren't there prettier looking ones, like transparent ones that comes with UV LED? can anyone please suggest a place or site as to where i can get those big exhaust fans in NZ? thnks so much for the help. |

A big fan does not necessarily run slower than a small fan, it depends on what it is designed for. However if you are satisfied with the flow rate of a high speed small fan, then the bigger fan can be slowed down to give that same flow and the noise level will be much reduced. Roughly the flow rate Q is proportional to speed times tip Diameter cubed, so if you have a fan of twice the diameter, say 180mm instead of 90mm, for the same flow the bigger fan need only run at 1/8 the speed of the smaller fan. Noise level is not so easy to scale: www.mne.psu.edu |

| 744647 | 2009-02-04 00:54:00 | 200mm is going to be the biggest computer fan you'll get with a 12volt DC supply AFAIK. www.pp.co.nz Otherwise you will be into mains powered domestic ventilation fans. |

| 744649 | 2009-02-04 01:36:00 | Antec uses the 'Super Big Boy' fans which are clear 25cm fans with LEDs for the Skeleton case. Though I've never seen it being sold separately. | qazwsxokmijn (102) | ||
| 744650 | 2009-02-04 02:14:00 | So you're after something like this? www.ubergizmo.com I use ones you can get from the Warehouse for approx $35, they're in a square container with tiny feet on either side. Works brilliant for my desktop :D |
