Corsair 650d modding!

juicemelon · 14 Oct 2011 at 23:02

Hey there - I've just finished my latest build (BF3 ready i hope

). My awesome rig resides in the beautiful case that is the Corsair 650d.
However i have noticed something that is slowly driving me insane. The top 200mm fan is really really noisy. I've installed the fan kit and swapped the screws for the silicone ones which did fix the fan controller hum.

But this is different, after a while you can see the fan start wobbling about and the sound is sooooooo annoying!
A slight tap to the top of the fan, and the sound is gone... for a few minutes

SO i figured, lets turn a bad situation into a good one... swap the 200mm for two good 140mms.
I'm thinking two fractal-design 140mms, and maybe swap the 120mm out the back as well

A good choice?

For now a t-shirt mutes the sound enough... for now.........

kinda depends on your preference of colours, but most people tend to go for these or the more expensive versions with yellow blades

Yes actually i think i will get the akasa 'venom' fans, as I have two on my cpu so the theme will look nice

.

I have a couple of questions if you don't mind. I plugged one of my cpu fans into the CPU_FAN on my mobo, and the 2nd into a CHA_FAN. Now they are both working just great but i've noticed the chassis one runs faster. Should i of split the CPU_FAN for both.

Next question is - The rest of my case fans are currently 3-pins running into the 650d fan controller (with fan kit installed). The akasa fans im after are 4-pins. Would i be safe to split a 3-pin on the fc into 3x 4-pins for my new fans

Sorry but this stuff confuses me

there will be a fan profile in the bios for the ones on the motherboard headers, you can change the speeds in there, I think that there is a program that you can use to change the speeds in windows, but I can't remember the name.

I'm not quite sure about the 4pin fans on the 650d fan controller, as I've never had any pwm fans myself

Think i found my answer to the first question here! - http://www.overclockers.co.uk/showproduct.php?prodid=CB-031-AK&tool=3
That way i can have two CPU fans being powered by the PSU but controlled by Q-FAN

Still need some help on the second one tho

mini-bump

OK, i have noticed that the fans are 3/4 pin so i could use them in the 3-pin fan controller directly but how would i plug them into a male plug that has the plastic shield on it?

Seems like its enforcing 3-pins only which seems a bit backwards

KiiYzOo · 16 Oct 2011 at 11:25

you could cut the shielded cover to let the 4pin connector come out the side of it

Hmmm, i would rather not tbh!
I might just stick with the fractal-designs. They are just 3 pins, and white won't look bad at all

I'd have a look at the Coolermaster Megaflow 200mm fans also, a lot thicker than the stock Corsair fans and quieter whilst pushing more air, if you don't like LED's you can just snip one wire on each LED to kill them, I've done that with both my Megaflow fans.
