Nexus NX-4090 blows air in instead of sucking it out
Hi
In other posts I have praised my Nexus NX-4090 for being a very good and silent PSU. I have however discovered a problem. Recently it began blowing air in instead of sucking air out of the case... it's really wierd because the fan is spinning the right way although very very slow (since I only have 2 hdds, a 2,4 ghz and a pretty old gfx card).
I am sure that my observation about blowing instead of sucking is correct. I tryed putting a peace of really thin paper beneath it and the psu pushed it away. When i put the paper to the exhaust it sucked it in. This is really wierd.
I have no other fans in my system so one fan plce right beneath the psu is wide open. I'm woundering if this might create some wierd airflow maby.
Right beneath the psu is a xp-90 with a nexus 92 mm @ 5v. Don't know if that matters.
EDIT: After some more careful testing the psu actually seems to suck som air in throught the the center of the fan. At the sides it seems to be blowing and ithe air behind the exhaust barely moves. Seems like its recirkulating the air within itself. The air like 1 cm beneath the cpu air intake is however still.

I guess that right next to the fan blades (especially if moving slowly) you can have some turbulence that is not going in any particular direction. To get at net airflow, you could light one of these smoking/smelling sticks (damn, can't remember how to call that in english) and see where the smoke goes.
