Fan Setup Recommendations

post #1 of 23
Thread Starter 
I'm with a HAF922 case. Originally, my setup was:

1 Coolermaster 200mm Megaflow Front Intake Fan
1 San Ace H1011 5.25" bay Front Intake Fan
1 Coolermaster 200mm Megaflow Side Intake Fan
1 Scythe S-Flex SFF21G Bottom Intake Fan
1 Stock 200mm Top Exhaust Fan
1 San Ace H1011 Rear Exhaust Fan
1 San Ace H1011 for my Megashadow heatsink

The 120mm fans are all connected in a Lamptron FC5 fan controller.

Now, I replaced all the parts of my computer except the fans. I know have a Thermalright Silver Arrow (which is considered to be the best heatsink right now. I'm better off just using the stock fans that came with it right? If this would be the case, I would have an extra H1011 lying around, should I replace the S-Flex SFF21G with this one?

Also, I'm reading that you can't use a side fan with this heatsink, so I guess I should remove my Megaflow side intake fan and replace the stock 200mm fan in the top of my case? Can I use 120mm for my intake?

Which do you think would be the best setup?

Thanks.

Oh sorry about that, edited the post.

well you COULD make the top fan an intake as well and then cut out your back grill and just don't have a fan there, let your san ace on your cooler exhaust for your case, or do a push pull and it should be really good.

Nah, I'm not a fan of making my top fan an exhaust since hot air "rises". Why do you need to cut the back grill and leave no fan there? Where would I put the San Ace as an exhaust for my case?

you mean not a fan of putting your top fan as intake? well it's true that hot air rises, but air goes where you push it. Hot air only rises in slow unmoving air. The air in the case is being pushed by fans, so it goes where it is being pushed, if you push cold air from the top, it will be fresh air used by your CPU, making it cooler, if you cut out the rear grill and have no fan, and assuming your cooler is in a push/pull config, the pull fan of your cooler will act as your exhaust fan and push it out, also because there is no grill to act as a barrier, all the hot air will be exhausted and provide better air flow

Sorry, yeah I mean intake. Ok. With the Silver Arrow being in push/pull config at stock, what will happen if I still use my San Ace H1011 as a rear exhaust without cutting off the back grill of my case?

And if the top fan is an exhaust fan, will it interfere with the airflow of my case from front to back? Which is why you are suggesting to setup the top fan as an intake for it to "help" in providing cool fresh air?

if the top front fan is an exhaust, it will pull the air out before it even reaches the cooler, so if you have a slower top front fan, it will provide cool fresh air

You mean it WON'T provide cool fresh air?

For me, temps lowered by ~2c when I set my top fan as intake. Please don't just blindly say "hot air rises" The whole point of case fans is to force the warm air to go where you want it.
