As for that post - many fans have that same issue. You need to put a little space between the fan and the grill.

In that way, can the PWM fan be controlled by the MB to be synchronized with the speed of the PSU fan? Also, why do you synchronize it with the PSU fan, where is your TY-140 located?

Would the rubber noise screws be enough for that little space needed between the fan and the grill?

A friend of mine just bought the Nzxt Phantom and was wondering what the best airflow configuration would be

Maybe the stock 120mm fans on the side (bring in air for the hard drives), a 140mm in the front, and move the stock 200mm top fan to the frontmost position and block off the rear one whilst removing the grill from the rear fan position?

He's going to have a 212+ for the cpu cooler so he won't be able to fit in a side 200mm/230mm side fan.


Here is how I do my phantom. I will be modding it a bit in the later future perhaps, but at the moment it works well for me.

front 140mm fan intake
2x side 120mm cm r4
1x side 200mm nzxt fan. (mounted on the outside, I have a 212+ also)
1x 120mm cm r4 in the 5.25" drive bay area
1x top front 200mm nzxt intake
1x rear top 200mm nzxt exhaust
1x rear 120mm cm r4 exhaust
1x 120mm fan behind the hdd cages to push air to the GPU

Very cool, how are your temps like that compared to the default setup?

Is it hard to mount the 200m on the side or do you just screw it in from the other side?

yup, i took off the side mesh and just mounted it on the outside. I swapped the stock rear cooler for the non LED version because it is faster and then put the LED one on the side. so my side fan lights up from the controller. the temps are much better than stock. I could do without half my fans, and it would be quieter too, but I like having some color lol

I have a CM storm sniper. For the longest time I've had my CPU Cooler facing my GPU with my top fan as exhaust. Finally switched my CPU cooler so that it exhausts into the rear fan, and switched the top fan to intake. I think* I've dropped temps at least by 2C, possibly more. Thanks for the info!

Power comes from the PSU. The speed control can come from a header dedicated to chassis fan speed control, but most would plug the PWM fans into the cpu fan header. This is what I do: two heatsink fans and one intake fan get their PWM control from the cpu header. Their 12v and gnd come from the psu.

Usually rubber noise isolators ("rubber screws" or "rubber nails") provide enough standoff to keep fan blades from scraping grills. Usually.

Ok, I got it now. I misunderstood you when you said you "synchronized" your PWM fans to the PSU, I thought you meant you synchronized your PWM fans with the speed of the PSU fans.

Here's a preview of part of the new airflow configuration I mentioned A couple weeks ago. My OS HDD died last weekend so haven't been able to upload any pics off my DSLR as they were shot in RAW. Will convert and upload as soon as I get everything up an running later this week. biggrin.gif

Have you looked into replacing the stock Lian-Li fans that came with the K62? I love how quiet the stock fans are, but I'm wondering if I could squeeze a bit more airflow out if I looked into some replacements. I read in the K62 thread that the stock fans are actually rebranded Yates that can do up to 51CFM.
