Adding a gtx 1070 to my mid-tower case (corsair 88r). Will it cause over heat problems?

Hi all, just build my first PC and want to add it GTX 1070.
The case as stated above is:
http://www.corsair.com/en/carbide-series-88r-microatx-mid-tower-case
Did not add any extra fans (There's the one in the rear that came with the case, and of course the fan that came with the CPU).
Considering the fact that the graphic card sits below the CPU zone and heat "goes up", do I need to worry about the heat created inside the case and buy one with blower fan (cause I understand they create more heat for the same performacne). Should I a non blower fan and add a fan in the front of the case to blow air inside?
Some more info about the PC:
Intel® Core™ i7-6700 Processor
GIGABYTE H170M-D3HGSM

Thanks

There are two major kinds of air coolers for GPU's, the most popular is "open air". Open air coolers have large heatsinks with several heatpipes, and often with two or even 3 fans blowing down onto the sinks. The advantage to this type is a large heat storage volume coupled with a massive amount of dissipation area, also they are typically quite quiet due to the use of large low speed fans. The disadvantage is that they dump all of their shed heat energy directly into the case, necessitating the use of more case fans or larger cases. The other type of cooler is the "Blower" style. These use a centrifugal fan which directs air through a large shroud and across a (relatively) small heatsink. The advantage to these is nearly all heat...

well the Graphics cards do have a "way" of pushing air out towards the back of computer, thats why in the back of the card (where the ports are) usually you will see a "grill" type of design, that's for air to run out that way. You should get 2 fans, you can mount of overtop and 1 to bring air in, to create better airflow. since you are running an i7 (a little bit beefier cpu) and adding a strong GPU it wont hurt.

These use a centrifugal fan which directs air through a large shroud and across a (relatively) small heatsink. The advantage to these is nearly all heat energy is vented outside of the case, disadvantages are excessive noise due to the high speed of the impeller and lower heatsink volume which can cause large temperature fluctuations depending on fan curves and hysteresis settings. Blower style cards can be used in smaller cases and are recommended for multi GPU configurations. As for recommendations typically I always recommend open air styles, the extra heat in the case is trivial to deal with in modern case designs. In addition they are typically lower cost with higher cooling performance overall. Blower style exist solely for specialty uses such as really small enclosures or SLI/CrossfireX and impatient people who can't wait for AIB models (See Nvidia FE fiasco, also see my sig... ;) )

Thanks for answering.

If I degrade myself to gtx 1060 are extra fans still necessary?

Some newby question:
Where exactly to locate the fans? my case has 4 options:
On top there are two opening. in the rear and in the middle.
On the front there are two option, on the bottom and in the middle:
lame profile sketch:
_ 2 _ 3 __________
...............................l
1.........CPU..............l
l ------GPU-----.........4
l..............................l
l.............................5
l_______________l

In 1 there's already the fan that came with the case blowing the hot air out.
If I understood you correctly (which I highly doubt), your saying to add another fan at location 2 or 3 to blow air out, and to add another fan at location 4 or 5 to blow air in.
I acknowledge the fact my experience in fan's location is absolute zero, but it seam like doing this, will cause the air flow to go from front bottom to rear top. In the middle of this sits the GPU, and in the end (getting the air after the GPU heated it a little bit) is the CPU. is that O.K? won't the CPU suffer from this?

Alon, I've used open air high wattage GPU's in mid towers before with little to no issue. If the GTX 1070 is you're desired/required GPU then stick with it. This is PC gaming we don't believe in compromise :) Anyhow to point.....get the card test the card, adjust cooling as required/if required. To start monitor your CPU and mainboard temps with some kind of freely available software, when you install your new card do this again noting any changes in temps and any CPU throttling issues. To be honest I don't foresee any issues, well none that require turning your case into a propulsion device anyhow.

(edit) Another thing to mention is that you can always get a different case, one more suited to your components and application if the current one is not.
