I plan on putting the h80i as intake as the back of the case (exhaust) then mounting a 200mm fan at the top as exhaust. Sound good?

If I have to take the 2 pictures you posted up there as reference, yes the upper picture is the way to go with closed water loops like H80. That's also why i mentioned midtowers. With bigger cases, usually you will have much more places to put intake fans and you need more intake because the interior space is big. However with midtowers being usually crammed, there are little options. Still, midtower cases have components a lot closer to edges, so exhaust fans creating negative pressure, the case itself just breathe from wherever it can (front meshes, floor grills, side grill, anywhere that air can be sucked in.

I think the case in the pictures is HAF 912, which I have.. I don't have any water cooling. I got 5+1(psu) fans in total. 20 cm in front as intake, 20 cm on top as exhaust. 12 cm as rear exhaust, 12 cm on CPU and 12cm on aftermarket GPU cooler. When I'm not benchmarking, I don't use the rear exhaust, only top. My rear exhaust is a silverstone 105 CFM monster thou. Noisy, that's why I usually don't use it unless doing benchmarks.

When I put side fan as intake, the gpu temp and cpu temps rise. When I put the fan as exhaust, the gpu temp drops and cpu temp doesn't change. My best setup is top and rear exhaust with no side fan. (And 20 cm intake for HDDs ofc, the air doesn't get past them)

Most custom loop users call them "wannabee water cooling".

Asetek has all patent rights on CLC and CoolIT is only other company making them. Asetek has filed lawsuits against CoolIT and Swiftech for patent infringement.

Front intakes do matter! Most modern cases depend on front intake for much of their airflow.

Often the front intake vents need better fans. Fans that have higher pressure / airflow rating to overcome the resistance of grill, fillter, HDD cage, etc.

As I said above it's all about flowing cool intake air to component intakes and flowing heated component exhaust air out of case without allowing it to mix with the cool intake air. With CPU's this is not much of a problem. With GPU's it is a nightmare.

The traditional "front & bottom intake with back & top exhaust doesn't work as well as it used to because new GPU's make more heat than CPU's do. Add the problem of them exhausting hot air everywhere makes it very hard to exhaust it from case without it mixing with cool intake airflow.

Saying your HAF 912 has average cooling is being more than generous... and not knowing what all you have in your system doesn't help us figure out how to cool it. We need to separate the airflow into 2 airflow patterns; one for CPU and one for GPU. We have to remove the heated GPU air without it mixing with cool intake air supplying both CPU and GPU.

My suggests are:
*Better intakes (which is a problem with 200mm fan).. what are your front fans now and how much do you worry about how loud it is?
*Remove as much HDD cage as possible.
*Add intake in 3x optical drive bays.
*Bottom intake if you can. Often need to raise case for better intake air access.
*Side intake/exhaust depending on what works best.. check temp of air going into GPU as suggested above.
*Remove unused PCI slot cover from back to hopefully let heated exhaust out of case.

It's possible reverse airflow may work. Using top and front intake with side and back exhaust. Problem is keeping heated exhaust coming out of case from being pulled into top intake.

Air is a fickled witch and often surprises us by not doing what we expect. Therefore all these suggestions are my best educated guesses of what will work.. and in most cases it does. But occasionally the airflow is not what we expected so need to be verified by what component and case temps do when they are applied. That's why I suggest trying different combinations and keep a record of all temps... component intake, room, component, etc.

I currently have a default coolermaster fan and antec tri cool as my intakes, they are silent, I do not mind a little noise since the h80i is pretty loud.

GPU is a 780 ACX so it dumps hot air into the case.

Again in a mid tower, bottom fans (floor) are not available. But there are grills there. With a midtower case, intake fans are marginal biggrin.gif Not many places to put them anyway. If the case allows for a floor fan, you can try that.

However, because it's a midtower, it's gonna suck air on its own just fine from Negative Pressure. With water cooling like h80, you can set its fan as intake on rear exhaust area. If not, rear exhaust must be well rear exhaust biggrin.gif However, believe me, side INTAKE FAN on mid tower is POINTLESS. Either try a side exhaust fan or leave it empty so gpu and cpu will breathe air in from there on their own. Side intake just upsets the air flow around gpu, gpu won't be able to breath air. You don't want turbulence around gpu area.

sigh.... you really should not be giving advice to people since you have no clue how cooling works biggrin.gif pretty much everything you said here is wrong biggrin.gif

I cant fit a 200mm at the top, only 120mm, how should i set my fans up

Well, i have an odd case then, the cooling works as I explained up there in this CASE. I also had a full tower case which I needed lotsa intake. Negative pressure didnt work in that TT Kandalf FullTower.

Yeah I have an odd-ball case. There's an interesting detail thou, I wonder if you saw that biggrin.gif

Whatever you can fit on top. And just load prime95 and test some setups yourself.

Yes and Yes.

A water cooler will help.

i happened to own an older and more expensive version of that case (Xaser III) that design is ANCIENT biggrin.gif mine was all 80mm fans if that gives you any idea of how OLD that design is biggrin.gif cases back then did NOT really care about positive / negative pressure because the ENTIRE machine drew less power then a typical video card these days biggrin.gif we are talking about pentium 2 to pentium 4 generation hardware here:D voodoo 5 was the king of video cards and nvidia wasn't even around biggrin.gif

thermal demands have risen significantly since the golden days of 80mm fans. and a great deal more care and research into thermal demands has been applied to the design of cases since then. the amount of airflow we are talking about today is like a fire hydrant compared to the garden hose of the 80mm era.

the good news is YOUR version of that case design is salvageable w/o modding since it already uses 120mm fans. mine requires dremel work biggrin.gif i also own a 80mm era lian li that i intend to put a 180mm fan into some day when i get around to cutting it up smile.gifbiggrin.gif
