Hi there tomshardware folks,

I was wondering how many fans I can still add. I have an asrock Z75 Pro3 mobo with a Cooler Master 690 CM III case. The asrock website lists: - 2 x CPU Fan connectors (1 x 4-pin, 1 x 3-pin)
- 2 x Chassis Fan connectors (1 x 4-pin, 1 x 3-pin)
- 1 x Power Fan connector (3-pin). The CM Case 690 comes with a 200 mm front fan and a 120 mm rear fan. There are still options for the top and bottom of the case. If possible, i'd like to add two on top and one on bottom (scythe slipstream). But from what it looks like, i'll use my 2 chassis fans for the cooler master one's, one cpu fan connector for my cm hyper 212 evo, and one power fan connector for my PSU. So I was wondering, is there any way I could still add 3 more fans? Also, I'd like to be able to control the speeds of the scythes, I've read they become really loud at 1600 rpm. I could also opt for scythe's 1200 rpm (same price essentially). Thanks!

how ever many controlers there are on the unit ?? if its a 4 fan controller then 4 fans 2 fan means 2 fans ?????

I guess from off the psu as many as you can daisy chain ??? find a molix or what ever to 1- 2- 3 - 3- ect - fan splitter ?? but there will be no speed control just full blast

something like this maybe as well ??

thers like 1000's of these items all you got to do is buy and try do some home work on whats best for your needs ?
a lead from the psu powers the controller and then the fans are powered and adjusted from it ??

just find one you may like a pull up its manual to see ...

example
http://downloads.nzxt.com/manuals/Sentry-03-manual-multi-language.pdf

this shows it has a cpu temp probe ? I don't think I would risk a good set cpu and it cooler over something like that unless I don't have a cpu installed yet ?? I'd just flop it to the side and not worry with it or maybe use it on the boards vrm or chipset to monitor them ??

Say I would link the case fans to the psu, how many could I possibly link? Also, since they're going to run on full speed, I might need to swap the scythes to something else. Any suggestions?
