Windows 7: Corsair 800D Question

No the fans are only able to be controlled by the mobo if they are both connected to the single 4 pin post near the cpu. I've found that with premium coolers with quiet fan or fans then it's best to run them wide open all the time. You may add a fan controller or a 4 pin to 3 pin splitter and run the cooler fans off the CPU fan post.

Even this is a 3 pin to 3 pin and it won't allow the fans to be controlled buy the mobo, only a 4 pin to 4 pin will and even then there isn't any temp. sensors involved.

I dont really care if they are running on full or half speed, but I would like to see how hot the CPU is so I guess I leave the CPU fans intact like I got them now and just try to figure out if I can do something better with them, my next trouble is to actualy find this adapter, I live in Sweden and I belive we lack a lot of small computer things like this. The link is the closest I have found Komplett.se - Akasa AK-CB001 Multi-fan Adapter but im not that happy about the 2 speed reduction ones since I want them to run on full power because I got a very small room, but I guess it wont matter that much if im planing on having 7 fans in the box taking up every spot.

CPU temp is totally separate from the PWM / CPU fan header. All the header does will control fan speed to match CPU temp if you engage that feature in the bios.

Im back again, I got my connectors and I got a slight problem, well I wanted to run all the 4 fans I have on 1 of these connector, but my 2 140mm noctua fans did not wanted to start on 5 volt connector, and I need to have 1 of the smaller fan that is on my noctua heatpipe connected to the cpu pin, if I dont have that I will get a CPU fan error notice when I start the computer and it dont want to continue booting. My question is if its possible to disable this so it boot anyway so I can get rid of the long fan cable that is now connected to my cpu pin

Yes in your bios should be a area regarding the cpu fan and heat warning and disable this as you know your fans are spinning off 12v psu power and the CPU is running max cool all the time !

I'm thinking about getting a 800D myself and have been looking around the Corsair H100 fits perfectly where the top fans would go and has excellent reviews. I'm unsure if you'd be interested and I'm a bit considered about the cooling in this case myself - as it's my first build - but the H100 seems like nice way to go.

I got the H80 with push/pull and my idle temps are around 35. with my i7 860 @ 3.77, max temps are around 60-67 I think so I bet your H100 would give even better temps
