Ventilation and case fan issue.

[Guest]

Hello,I just bought a new GPU EVGA GeForce GTX 970 FTW ACX 2.0 a week ago and I have found out that my pc have ventilation issues.Due to this ventilation issues,my cpu temp have been ranging from 70-83 degree celsius while gaming because there is not enough room for the hot air to exit out of the case.Instead of getting a new case,can I install a case fan at the back of the pc to blow the hot air out since hot air rises? My cpu fan is facing the side of the pc.
My gpu is an axial gpu.

The interior of the pc looks like this:

My PC is an Acer predator G3-605 which doesn't have any case fan included.

Yes, there should be a fan at the rear of the case to exhaust the hot air; I have no idea why they did not include one there.

Hello... Yes there is a cut-out and mounting holes for a fan... measure ( mm ) mounting holes diagonially... and order/buy and mount a fan with air flow out the case.
You can get Fans at office depot/Staples/Best Buy, locally to fit it.
1) 12VDC 2-wire molex connector Fan to your Power supply connectors.
2) 3-4 Wire/Pin mini connector Fan to your MB Sys_Fan connector.

A 4-wire fan wiill give you speed control through the MB Bio's.
A 3-wire and 2-wire Fan will give you single speed only.

Sorry,just to clear my doubt again. Without any case fan,the side panel gets very hot even though there are holes on it. So by applying a case fan at the back of the pc, I'm assuming it will solve this ventilation problem I have?

Hello... You have two choices
1) run your computer without a side panel.
2) install Fans to Pull outside air through it.

Your Graphics card is the largest producer of heat in your computer case... using the ACX type designed Video card, ONLY re-circulates the HOT air it produces back into your case... a "reference" designed card with "external exhaust" will EXIT the hot air for you... Thus you need to add a FAN to do the same thing with the ACX Fan cooling design Card.

Ok,I will try buying a case fan and install it on the rear of the pc. I only have enough space at the rear of the pc. The rear case fan is supposed to push the cold air into the case or push the hot air out of the case?

Hello... Depends... experiment here... and read your temperatures with it mounted both ways... How and Where your Case is located in your Room can make a difference too.
Power supplies also Pull and Push Air in different ways... try to design/make a Air FLOW from outside Cool Air into and out through your computer parts.
But if we are to use SCIENCE here... HEAT always rises... and the top most part of your case will have the HOT air... Use the Highest Fan to PUSH it out of your case... so it is Typical Design to have Cool air come in the bottom and then exit out the Top.
If you are good with tools... You can mount one on your side panel Too...
Is there a pre-Cut for a front case fan? alot of case have those too.

The rear fan is for exhausting hot air out of the case.

No,there is no way I can include a front case fan, only the rear and side.
