Side panel fan or no...

post #1 of 18
Thread Starter 
I just destroyed one of my fans when re-wiring my case and pulled my side panel fan out to replace it, that got me wondering if there is any real advantage to using a fan there....I mean when I think about it from the perspective of fluid dynamics it would create turbulence when hitting my other airflow stream (from the front to the rear of the case) making the cooling inefficient and I have a Coolermaster Hyper Tx3 so the panel fan isn't even feeding my cpu cooler..Does anyone know anything about this? Should I bother to spend the money to replace it?

yes, side panel fans help the cool airflow to your gpu

It helps cool the GPU but you don't really need extra cooling for a 5670. Also if you have sufficient front intake it's not necessary and probably harms airflow more than it helps.

The only time a side panel fan might really be needed is if you're running two or more cards that are close together and are starved of air.

I say use a side pannel fan, It helped on my sigle GPU rig, I also replaced my PCI slots with vented ones, so that airflow is not disrupted. I saw a nice drop in GPU temps allowing for further OC

I have a modded pci cooler that helps move stagnant air from the bottom of the case to the gpu intake, I also have 3 interior fans moving air past any cables/obstructions from the front intake fans, I don't know if my gpu will benefit any since I already have extra mods to help move air all about my case. I am doing a write up about using dry ice vapour to check for dead spots and airflow in your case...I tested my temps they decreased on my gpu after removing the panel fan oddly enough, and my cfm has increased but not by much...

I also forgot to mention that my panel fan sits over top of the cpu cooler and is not near the gpu at all..

If this is your case, you should have a lower fan location for a fan to intake at your GPU, dont use the uper fan mount as its useless, it would be best to block of the uper fan mount on the side pannel and use the lower as an intake for the GPU.

I ditched the side fan it's useless on my rig, and my system is neutral pressured so nothing is being sucked into the two ports on the side so I think I found a good balance.

Really? hold a pice of paper/napkin over the opend hole on the side of your case. I'll bet it sticks, this is becouse the exhaust fan's will pull air from where ever they can.

Nah I have my fan controllers adjusted, and I have used a dying match next to it to see if the smoke was sucked in and nada...
