Fan splitters

[AndThenThereWas1]

(im a total noob)So i have multiple fans but i have a limited amount of fan connectors. All the fans are 4 pin fans. When i use a fan splitter, do both fans get the proper energy to run at max or do they only get half the power. Secondly, how accurate is the rpm readout when splitting the fans? for example i have 2 noctua nf-f12s in a single connection. The readout is about 900rpm. Is that accurate?

What are you using to control them a fan controller? If so which one. If you use a fan controller you should be OK if you hook 2-3 fans depending on the wattage per channel some controllers are rated 20-30 watts per channel. The motherboard fan controller you might be limited on how many fans you can put on 1 fan header

Im using my Asus maximus 6 extreme motherboard.

after reading about your board you will need a fan controller because those headers are not capable of running multipul fans check this out

If i use a fan controller will the readout be correct when controlling multiple fans with 1 header?

Well yea when it comes to fan controllers you can hook more the one fan up. Let's take a fan controller that uses 30W per channel and you have 3 fans that run at 10W well that means you could hook up 3 fans on that one channel.

I have 10 fans and most fan controllers only have 4-6 connections. I would have to split several of the fans. Would the readout on those fans be accurate?

To my understanding yes.

Since you are using 4 Pin PWM fans you can buy a powered PWM splitter which uses the PWM signal from the motherboard and the power direct from the power supply.

 

Swiftech make an 8 way PCB one and Akasa make a 4 way cable one. However both of these will only give you the speed readout form one fan but honestly if you're using all the same fans it won't matter as they'll all be spinning at similar speeds!
