i tried with mixed fans but ddnt work out so good..

phanteks has a newer hub available from what ive heard that gets true pwm and sends it out to either 3/4pin fans..your gonna have to ask sm1 else about your issue there..might be a bad hub/ a dud?

Of course that hub will work for 4 pin fans... If you supply 12 volts to 3 pin fans it does nothing. It's just a splitter.

And yes I have 2 of the new style fan hubs... I've tried a variety of fans and believe me it doesn't work. The controllable range for my ap-15's is 1500-1850 rpm then to 0 using a pwm only signal from the board. It's nothing more than a hub at this point which is no different than the nzxt grid.

The phanteks hub has been discussed a lot. I've even offered to send mine to anyone who has electrical knowledge to test it but no one seems to care.

As for rear and front yes please do change, rear fans are also same as above (swiftech helix) and front as well.

Thank you Dave (very quick answer)!

Just to avoid any confusion I suppose that with "intake" you mean fresh air from outside coming inside the case and, vice versa, with "exhaust" you mean hot air from inside going outside.
So is this design wrong:
and the only exhaust I need is in the rear?

I suppose you are talking about 120mm fan(s). You said CM JetFlo is good fan and I like it more than swiftech helix. Can I use JetFlow fan(s) instead?


Someone suggested to specify everything I'm going to put inside the case (thank you X-PREDATOR):

CPU 4970k
MoBo Asrock Asus MAXIMUS VII HERO
RAM Corsair 2xCML4GX3M1X1600C7
Power Supply XFX XTR, 650W
SSD Plextor m6e M.2 2280 256GB
CPU Cooler Noctua NH-D15
Case CM690III
HD Seagate Barracuda 1TB ST1000DM003
GPU GTX 970 (not sure about the brand yet)
Your case has:
1 x 200mm/180mm or 2 x 140mm/120mm front fan mounts (200mm fan included),
1 x 120mm rear fan mount (fan included),
1 x 200mm or 2 x 140mm/120mm roof fan mounts,
1 x 200mm/180mm or 2 x 120mm left side fan mounts,
1 x 120mm bottom fan mount,
1 x 120mm internal HDD cage mount (fans not included)
You want as much exhaust vent area as intake fan area. If you do not the fans are trying to push air out of less space than they are bring air in through .. and only as much air as is exhausted from case can be enter case.
You may find link in sig for case airflow helpful.
post #1648 of 2323
front ..bottom..side-all intake
top ...rear...-all exahaust full blast on these two..will get the hot air out the case quicker..
post #1649 of 2323
Hot air cannot leave case any faster than cool air is coming into case. It's a simple matter of displacement. Air coming in must have same amount going out .. air going out must have same amount coming in.
post #1650 of 2323
What about if you have 4+ intakes and 1 exhaust. The 4+ intakes would create more air pressure forcing the hot air out faster, no?
