Amazing static pressure PC fan

[stealthENG]

Hi there. Im building a grow box but I would like to know what pc fans there are out there that I have missed which have great static pressure ratings. ive Looked @ most Noctuas and for their price they seem over rated.
Here http://www.ebay.co.uk/itm/310311364713 I can get 2 very quiet fans with:
Air pressure (mmH2O)
3.04 mm H2O

for the price of one noctua.

Am i missing something?

There is no way that thing will work with any kind of resistance, looks like a standard pc fan.
