Meshify C airflow Question

[FurrBall]

Hey! 

 

I have question about airflow in my PC case(Meshify C). 

Gpu temperatures are tad high, around 77/78C (171/173F) in games with unlocked framerate like DIRT 2 and 81C(178F) in Kombustor benchmark. 

With glass panel taken off temps drop around 4/5C lower 

 

I have added 120 mm fan as low as i possibly can ( i need to buy adapter 140 to 120 to properly mount fan in that position ).It helped somewhat, temps are about 2-3C lower.

 

When I replaced 120mm fan with 140mm (first picture), I have created hot air vortex between fan and GPU as gpu exhaust hot air on their sides (2070 Super Ventus) when i put hand between Gpu and fan it is very hot there. generally GPU temperatures are also higher with 140mm fan.

 

So my question is how I can  improve airflow and GPU cooling (CPU is around 55C, max 60C for short peaks underload) in this PC case. 

Is it  the best solution to mount this 120mm fan(BeQuiet Pure wings2) as shown on second picture?

 

Please, do not pay attention to the cables, I am currently mounting HDD on the back. Normally  cables do not block the air flow. 

 

And apologize for my english, its not my native language and I am trying my best.

thank you in advance for the help I really need it.

80 degrees is normal temps for a full load gpu

That ventus cooler is just a bit small for 200+ W card.

where i live its 30 degrees ambient , so it will always go that high , the temp is capped at 80 degrees on the gpu and never go higher , if u want u can manually set the fan higher so it cool a bit better but will make a lot of noise

My gpu loads at 62 using the secondary bios fan curve running heaven. More airflow wouldn’t hurt.

So I understand that I wont be able to drop GPU temp much lower but still, is it more optimal to mount small fan (120mm) just below GPU or leave 140mm fan?

Anyway thank you for all the answers so far!

I have my 3 fronts populated as intakes, I have 4 in, 3 out with my Meshify. It works great, but its not silent. Not at all. I run my fans at 5-7v for the most part, because at 12v they are hairdryers. Brute force tactics.. very effective.

Hard to tell but the difference would probably be small.

Your temps are fine so you can just leave it as is. 

Computer components tend to get fairly hot for human touch and be fine so I wouldn't recommend how comfortable your hand feels as a reliable benchmark.

I installed a smaller fan(120mm) and it seems to me that the temperatures are lower

After 10 minutes od msi kombustor temperature stays at 77C( ambient temperature is 27) 3dMark 76C (after 5 runs) 

And 75C on COD with unlocked framerate

I used the noctua adapter(140mm to 120mm) to install the smaller fan.
