one fan blowing into another fan bad?

[grimlykindo]

Sorry to confuse anybody with my weird question.

I have a dell 4700 and I'm stuck with a proprietary cpu heatsink. Its actaully tall and skinny like a tower heatsink. I have a 92mm fan attached to the right side of it blowing through it and towards the rear and then goes right into my rear exaust fan. It seem to work great cause the heat just goes right out the back of the case and never hits the ram or mobo. Downside is that it seems to create some turbulence within the case. Is this bad? I really don't know enough about airflow and physics to tell. Thanks for your time

p.s. the airflow is like this-


Out<---<80mm fan<---<CPU heatsink<---<92mm fan<--

Both fans are facing the same way (make sense?)

Not really bad. If it works, stick with it.

na, as long as your temps are fine I would not sweat it.

thats sorta similar to my setup...i kind of have my case sectioned off into virtual cooling sections...the CPU area gets intake from a top blowhole, which feeds the CPU HSF, which is then shot out the back by a Tornado exhaust fan. a bit noisy, but very effective.

I though the point of a blowhole was to remove hot air (hot air rises) from the top of the case???
