Alright. So.

Fan Xpert in Asus Suite III wasn't functioning properly. It would only read the CPU fan. Now it might have had something to do with me having 8 fans inside my case. And 4 of them are connected to one header via a 4-way splitter. That must have been the issue. Well no. I went to UEFI, loaded optimized results, went back to Fan Xpert and voila, problem solved, it recognized the two on my CPU, the one in the back, the one in the bottom, and the four splitted ones (two front, two back) as one fan, which is fine, cause they are all the same anyway. Now, I have previously had everything set to manual mode in UEFI to what I figured was optimal to get the best temps at lowest noise possible.

BOY WAS I WRONG!

After fiddling about with the fans in Asus Fan Xpert, they are now quieter and by a lot and my temps have gone down. GONE DOWN. I was idling at 38c on the CPU, and now while in Chrome writing this I am at 33c. WHAT THE HECK. Now I am confused as to how fans actually work right now! It's a pretty standard push-pull config with mine, though.

- The two front ones and the bottom one are the intake.
- The two top ones and the back are the out-take.
- And I have two fans on my Hyper EVO 212. The one closer to the back is pulling the air out towards the back fan, and the one closer to the RAM is pushing it back through the fins. So generally in the same direction and out of the case as fast as possible.

Here are my questions:

1. How much do the chassis fans REALLY affect the CPU/GPU temps?
2. At how much should you keep your chassis fans while gaming?
3. At what temperature should you set your CPU fans to run at 100%?
4. Is it possible that the chassis intake fans were pumping so much air into the case, along with high CPU temps that it just got too hot, too fast in there, so that even with the out-take fans running full speed it couldn't get rid of the hot air and cool everything down enough?
5. Should you keep your intake fans a bit slower than the out-take?
6. Are (multiple) chassis fans overrated?
7. I'm so happy right now, because I almost opted out for a water cooler, just to keep everything quiet. BUT THAT AIR GOT ME HIGH RIGHT NOW. I CAN'T LIVE WITHOUT THAT AIR YO.
No, I mean literally, I would die... :??:

Well I hope I get some answers, and maybe this helps someone out having issues with cooling their case or with Asus Suite's Fan Xpert III. Peace!

no one calls them outake fans. we call them exhaust fans.

1. chassis fans affect the cpu/gpu temps significantly.
2. it should be set automatically unless you want to manual control them with either the asus fan xpert or a fan controller.
3. probably 70C or whenever your core temperature is at full load ( http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html )
4. air outside the case should technically be cooler than inside the case, so heat inside the case should be expelled outside the exhaust. if there is no exhaust and only intake along with dust + overheated components, yes it is possible to not be able to cool everything.
5. does it matter? usually u have 1 exhaust fans and 2 intake fans with higher cfm anyways, showing the importance of cool air intake than trying to exhaust hot air. however, both are necessary to keeping your pc cool
6. depends on the computer's profile. if you're performance-oriented, you want extra fans. if you're more conscious of having low-profile and silence, you want less fans.

Sorry I'm not a native speaker so I'm not down with all the terminology.

1. So how come when I set my chassis fans to a lower speed, I got lower temps?
2. I want to find the optimal sound/efficiency point (not having to rev them if the result is worse or same)
3. That is what I set them to, opposed to before, setting them to max any time I was gaming (and am having 10c lower temps now)
4. But there is exhaust. 3 exhaust and 3 intake fans. But slowing them down to about 70-80% instead of 100 gave me lower temps. I wanna know why.
5. I have the same fans frontside and back.
6. I am performance oriented naturally, but have figured out I could have silence when doing simple tasks and that all my fans should not be at 100% while gaming, silence aside. Having chassis fans at lower speeds gives me a cooler performance.
