Cooling my new rig

[spda]

Hello

I need some help with cooling my PC components mainly the GPU.

I use the CMS(cooler master) 690 III mid tower case with the built in 200mm fan at the front (intake), 120mm at the back(rear-exhaust)

I have the window edition with no air ventilation holes or fans at any side of the case

I have a corsair h100i installed at the top with its stock fans in the following configuration:

Top of the case

Radiator

Fans moving air downwards(intake)

The cpu( i7-4790k) is cool, but when I ran the valley benchmark stress test thingy for my evga gtx 780 sc with acx cooler it went up to 80 degrees C ( the GPU) which made me worried

I think I have space at the bottom of the case for probably a 120mm fan

I was considering using the radiator fans as exhaust but I assumed that it would mean cooling the radiator with hot air which is less Efficient and could make the CPU hotter(just an assumption)

Any tips for what should I do with my system? Like should I purchase a fan and install it at the bottom of the case, intake or exhaust, silent or performance, notice that the case ha space beneath it because it is lifted from the sides .I don't plan on changing the stock case fans because that would be a waste for them

P.s I didn't know where to post this, hopefully in the right place and thanks in advance

IF there are any things in the case that would be blocking air flow try moving them, such as cables or hard drives.

whats ur current gpu temps? and is this all ur fans in the system 1 front intake 2 top intake 1 back exhaust.

and is ur card a blower design or nor reference design

Never put a CPU cooler on the top of the case as an intake.

Dust falls, and will easily get sucked in to your case.

Heat rises, and the fans are pushing air downward, not where the heat wants to go.

Work with convection, not against it.

No wires blocking airflow

Around 29 degrees, custom cooler with 2 fans called evga ACX cooler

So I should flip the fans ?

Yes always use top as exhaust. If you need positive air pressure, flip the rear fan to an intake and put a magnetic filter on the back.

If GPU is only part which is heating up, you could think of changing front intake to something more powerful. 200mm fan is good for basic intake but 2 140mm fans can be bit better. This depends on their specs ofc. But they would target airflow more towards GPU, not all around the case.
