Is running the liquid cooler radiator fan on 'exhaust" suicide?

I recently purchased a thermaltake case for my new computer, and the fan on the CPU is LOUD.
I bought corsair C80 liquid cooling system to quiet my system down.

The C80 Liquid Cooler unit has 2 120mm fans, and I know it should blow from outside the case to the inside so cool air runs over the grill.

I cant install the cooler fan to the open spot in the bottom of my case because the coolant hose wont reach. The cooler hose can only reach the rear fan.

I am guessing the best thing to do would be put the cooler fan in the rear as intake, then add another fan to the bottom as an exhaust. I would then have 3 intake and 2 exhaust, but I am destroying the "flow" of air through the case then.

I don't overclock and I'm not the kind of guy that gets excited if my CPU temp drops a little.

In summation- do you think this is the best way to do this?

TL;DR - my current computer case has a 'flow' of air from one end to the other. If I move the fans no longer have that 'flow'- is there going to be a significant penalty for me?

SPECS:

it won't affect it much. Air inside the computer case is usually 3-5 degrees higher with good air flow, so thats how much higher the temp will be by putting it on the exhaust side.

With bad air flow however, it could be as much as 10 degrees or more. Looks like from the ammount of fans you have, the air flow should be pretty good.

One thing to keep in mind, you can't reverse the air flow from your ps or the graphics card. trying to reverse the flow through only half of the case may end up worse.
