I have a Lian Li PC6070 and I just realized that the only exhaust fan I have is from my PSU. The fan on the back is an intake fan because there is a CPU Air Duct kit that usually comes with PC6x cases, mine doesn't have this.

I am wondering if this can be bad?

Would it be smart to make this an exhaust fan? If so, how would I do this? Just turn the fan around?

Thank you.
 
I have a 6070....the rear fan is an exhaust fan, the two in the front pull in cool air ! they are quiet fans, and I have since replaced them with panaflo H1A's....keeps the noise down but ups the airflow...I have no problem with cooling now ! Just remember the intake is under the front usb ports and need to be kept free....and occasionally cleaned, there is a piece of foam filter in there !....yes just turn the fan over ! there is an arrow on them to let you know which way air is flowing. I also cut away the rear exhaust grill to keep things quiet and incrase airflow....just don't do it with eveything installed if yoy do !

Thanks for the advice, the two in the front are fine...I made a little stand for the computer because the intake port was way to close to the carpet which made me quite nervous about the computer getting adequate airflow.

I ordered a much less restrictive grill for the back and I will flip the fan a little later today and let you know how everything went.

Thanks again.
 
Those intake grills cut down on flow quite a bit. I dont have a case like yours, mine is a raidmax. I used the stock 2 intake fans, they were noisy and didnt flow much. The problem was, the stupid grille was too close to the fan blades, making a lot of noise, and not much flow. Out came my dremmel, and they are gone.

Now, I can hardly hear them, and the exhaust air isnt hot enough to cook food with.
 
Well I just flipped the fan and everything seems to be going fine, I am going to watch my temps pretty carefully for the next hour or so to make sure everything is fine.

Edit: One thing I have noticed is that one of temp readings is jumping ~10C every once in a while. It will go from 22C and jump to 27C for a second or two and jump back down, any reason for that?
