Slow front fan, good airflow?

post #1 of 7
Thread Starter 
Hey OCN! I've had my 922 for a while, looking to find a new case... Just now i've noticed the front chassis fan seems very slow, going only 700 RPM, I'm also wondering if my airflow is as good as possible.. The light blue indicated intake, red is exhaust, green is my GPU radiator, and light green is my hyper 212 + fan. Any suggestions? And does anyone know how to make the top exhaust fan and front chassis intake fan faster? I feel my computer is gasping for air since the front is so slow.

261

These RPM's are when I am using prime95, thats why the CPU fan is hovering around 2000.

They are 200mm they can move a lot of air at a lower RPM. No you can't make them go faster than they were designed to run. The front fan doesn't do much for airflow in the case IMO as it really just cools off the HDDs. You can add a front 120mm intake into the the 5.25" drive bays if you have enough room for it as it takes up 3 slots, though I don't know what good it will do you with the Top fan being exhaust. Bottom intakes to me don't seem like they do much, you could also add a side fan I think the 922 takes up to a 200mm on the side.

Just realized the intakes on the side ;P

Edit: Also seeing how you are in the market for a new case I would suggest a HAF X, HAF 932, Storm Trooper, or NZXT Switch 810.

Are they or have you tried them plugged into a fan controller? I have my back exhaust on my M59 plugged into my mobo and it reads 1700 rpm max but the fan is rated at 2000 rpm. My front intake is the same model plugged into a 20w Rheobus fan controller and it seems to be run faster when turned on high thumb.gif

I don't have any fan controller to plug them to. I tried using speedfan as an alternative but using it doesnt do anything to my fans, just shows temps. I might be doing something wrong..

I might add these as my 120mm fans for the 5.25" bays, but how will I get it to not move? I took a look at the HAF X's exhaust and it's pretty much the same intake & exhaust as the way I have it now. What's wrong with the top exhaust? When i'm prime 95'ing, thats the area that gets the hottest actually. I do agree the bottom intake doesn't do much, I just have it there cause I wanted to fill the gap tongue.gif

Took the bottom fan out and put it on the 5.25" bay, nothing is stopping it from moving atm but i'll put some zipties on it tongue.gif My temps actually dropped 3/4C just from that fan switch. I bet if I could get front 200mm fan to go 1000 rpm, if possible, i'll be set thumb.gif

Buy a fan controller if you want to get the max speed out of your fans, I think I paid about $15 for my Rheobus and it works great for the price thumb.gif

What about the scythe "Kaze Q"? Looks pretty good for the price, and all I need to control are 3 fans, possibly 4 in the future.
