Good question,All i know is they give you 3 Coolermaster fans with the case and i read that theyre actualy quite good,I also have another 2 Gigabyte 120mm fans which i intend to throw in there too.
Im hoping it will be quiet,If not this post will help me too
Got my CM690 today, man its a beast. Also got coming two 140x140x25mm CM Fans which im going to mount on the top of the case.
Just got a question and I hope its good lol. With the two fans mounted on the top will my Coolmaster V8 HSF still fit? Cause that thing is equally massive.
The Coolermaster V8 fits like a glove in the 690...at least with my motherboard. I have about 1/4 inch to spare with 120mm fans that are 25mm thick mounted in the top.
My system is all done now with my new case,I added a extra Gigabyte 140mm fan at the top,I also have another spare 140mm i could throw in there too but its not realy needed tbh.
I have my fans connected through a fan controller too so its super quiet even with the stock Coolermaster fans they give you
I have bought my Dremel, all new black screws, fan grills, sleeve kit, new Zalman fan controller and a few other things. The entire case will be modded
To answer your question of "What's a fan controller?", its a small box that measures either 5.25" or 3.5" and there are knobs on front. In the back there are cables that run to your fans and basically you can adjust the speed of the fans.
Does the power from the PSU plug into the controller, the the controller plugs into the fans?
What exactly does it do? Measure airflow or something, or is it just a big resistor that varies the power supplied to each fan therefore controlling the speed?
It supports different amounts. You could have one for 4 fans but you may also have one for 8 fans so you'll be fine. The Zalman fan controller I sent has 6 ports and its only 29.99 so its pretty good.
