I'll be building a computer for the first time 5-6 months from now. I'm having no trouble researching all the important stuff, but I've come across a (relatively) minor issue that I can't seem to find much about. The lack of importance and lack of information are probably related, but I'd still like to know all I can.
I understand that system fans can be controlled by the motherboard. I'd like to do that if possible, as it seems like a more elegant solution then simply leaving them all on max all the time.
I'll post a few of the relevant parts that I've been looking at. Just for context though, as there is no way of knowing what my actual build will be 5 months down the line.
CM 690
GIGABYTE GA-MA790FXT
CORSAIR CMPSU-650TX
Ok, now some questions to give an idea of the issues I'm looking at.
If I power the three fans on the CM690 directly from the power supply, will they simply run full speed all the time? How loud would they be in that event?
From reading, it looks the the CM690 comes installed with 3pin fans. My understanding is that the fourth pin on some fans is for speed control, but that 3pin fans can typically be controlled anyway. Is that correct?
That motherboard, like most of them I've seen, doesn't have 3 system fan headers. It is listed as having one 4pin and one 3pin.
If I plug one of the 3pin fans on the CM690 into a 3pin header, would that fan have its speed controlled though the motherboard?
Can I plug a 3pin fan into a 4pin header, and would it likely be controlled?
I've actually seen people say that you should NEVER EVER plug a single system fan into a header specifically designed for system fans, for fear of blowing the motherboard. You see a lot of people online proving how tech savy they are by repeating bad information they have heard from other people trying to prove how tech savy they are, and that is what those warnings most look like to me. I'm not an expert though, so I could be wrong.
The warnings to never connect two fans to one header using a splitter strike me as a lot more credible. How great a risk would that be? Obviously it would have to be near zero to be worth it. If there is very little risk, would two fans on one header both be controlled?
I've also noticed that a lot of motherboards have headers for a power fan and northbridge fan. Are either of those typically used? If not, could you connect a regular system fan to one and control it through the motherboard?
This is all the sort of stuff that I have learned absolutely nothing about from doing upgrades over the years. I realize it's not the most important issue around, but I figure someone who has built a few machines might know enough to help me out.
