Hello. I have the following setup:

Fractal Design Define R4 Black Pearl
XFX ProSeries Core Edition 750W PSU
Intel® LGA1150 Core i7-4770K
ASUS Z87-A, Socket-1150
Crucial DDR3 BallistiX 1600Mhz 16GB KIT
1 stk MSI GeForce GTX780 3GB Gaming PCI-E
Kingston SSDNow V300 240GB 2.5" 7mm OEM
Corsair H80i Hydro Cooler

so i have the setup like in the picture below(sorry for the bad mspaint job :p  )

Im currently playing some games and i can see that my CPU reaches around 80c which for me seems a bit high. Does anyone have any suggestions for re-arranging the fans for better airflow/cooling ?

Well I would make sure that the heatsink is installed correctly because that does seem quite high for water cooling. Personally I would remove the heatsink clean the thermal past make sure the heatsink and CPU are both clean and then re apply the TIM and re attach the heatsink. Did that heatsink have a plastic film covering it? Make sure it is removed before re attaching it to the CPU.

Lastly do you only have a total of two fans in your system? One on the front and the other one attached to the H80i? I would at least get one for the top of the case blowing out.

The R4 comes with at least 2 case fans, 1 in the front (behind the door) and 1 blowing out the back at the top next to the i/o panel

Yeah, i removed the stock cooler and cleaned the cpu from the old thermalpaste. The plastic film has been removed aswell. The h80i comes with pre applied thermal paste
The is a total of 4 fans in my system. One in the front and one in the top sucking in air. Then there are 2 fans on the h80i. Both are pushing air out of the computer(just like in my "chart").
Just to mention it, my computer do idle between 28-32c which from what i can read is quite normal. Its just when i play it gets very hot.

your H80i uses the hot air of the pc to cool the cpu, especially if you have a custom cooler on your grafic card. Turn it around. Let the H80i take the air from outside the case an pull it out with the fan in the top.

Wouldnt that mean i get negative air pressure with 2 fans(on the h80i) and the one in the front sucking in air and just the one in the top pulling air out?

You'll get positive air pressure. More air in than out. That's normally good as dust will not be sucked in through all the wholes, but pressed out. What you should do as well is to buy a dust-filter for the rear-fan. Than you will have nearly no problems with dust in your case.

But you can also try just to turn around the fan in the top, this should work better than you current configuration. Or you try to put it in the bottom to suck air in - than you might be able to close the top again for more silence.

If you don't have much harddrives you should put the in the bottom cage and take the upper cage out. Than you can install the front-intake there, or mabe bothe fron-intakes. You should also check your cable-management to get good qairflow.

Alright, i will try changing the fan at the top to pull air out instead. As for the harddrive cage ive turned the top one(the big one) so air from the front fan is directed right at my gfx card, that option was recomended instead of taking it out completley.

U have alot of suggestions which i appreciate, but which one do u recomend the most? remember i got 4 fans at the moment and 2 of them are on the h80i.

Take the hdd-cage out and clean your cable management. Avoid anything that blocks airflow.

For the CPU the best would be if the H80i gets cool and fresh air from the outside. This will drop down CPU-temps. As the warm air from the H80i will be sucked out by the top-fan, this warm air will not heat up other components like the GPU. The GPU itself gets fresh air from the front fan - a part of this will be pressed out at the bottom-rear (PCIe-Slots e.g.), rest will be sucked out by the top-fan. You can also turn over your PSU - this will help to suck out warm air from GPU. That's your 5th fan ;-)

Thanks, ill reverse the fans when i get home and take out the cage. As far for the cables all are pulled on the back and doesnt interfer with the airflow at all

so ive now reversed 3 of the fans and the result is about the same, ive managed to lower it to around 70-76 degrees when playing but it still seems to high.
Here is a picture of corslink and my fans showing the direction of the airflow. I also removed the top hd cage to increase space and airflow and put the fan above the second cage instead of blowing directly at the harddrives.

Then you cannot do anything more to improve airflow.
Did You overclock? What voltages and speeds?

No nothing is overclocked, i was going to overclock but since the temps are really high already i wanted to address that problem first. Im thinking of buying aftermarket thermal paste after all and re install the cooler towards the CPU, even though ive read corsair uses good thermal paste. But since i got 87c with the stock cooler and now around 75 with the H80i im having problems thinking the thermal paste thats the issue. And yes i did clean it between changing coolers

Best solution

This temps are not normal without any OC. Are you shure? I've already seen people that made an OC or overvolt by mistake. Maybe you should load default bios settings agein. And - if you want to overclock - to undervolt first would be a good idea. Maybe you have not activated energy-saving options in bios?

Double-checking thermal paste is a good idea as well - maybe you added too much?
What temps (and fan-speeds) do you have idleing?

EDIT:

You should also check CPU-Z (volts) and you should maybe use another program to check the temps of the cpu. Do you have big differences between the cores? A bios-update should be done as well if you haven't.

Alright @slsPCs you probably solved my problem now :)  When you mentioned bios i thought that i didnt touch anything while i was there but acctually i did. There is a setting right at the start that you can set the bios to performance, power saver and such. I put it to performance because i do play alot of games and i didnt think it would acctually oc the system.
I put the bios back to default and when i saved changes i saw a ton of changes it made to the bios when i hit save.

I just tried running BF4 again and now the system is stable around 58-62 degrees which is perfect! That is also with the fans set to 950-1000 rpms which is the same i have when its in idle mode. In idle the temp is around 31-34 degrees.

So stupid of me not to even think that the bios setting i changed didnt matter. Anyways, a big thanks to you, you've been very helpfull.

Btw, from what i can read the system doesnt take damage from running at 70 degrees so putting it in performance shouldnt do to much, right?

Nice.
Doing the OC by yourself would be the better way.
