How to increase airflow in sharkoon tg5 case

[dubisk]

I uploaded a picture of the inside of my case, the specs are: asus h81-m mobo, i7 4790, gtx 1060 6g (Palit StormX), corsair Vs 650W and a sharkoon tg5 case. The 3 fans in the front are intake and the rear one is an exhaust fan, the two fans on the cpu cooler are in a push pull config. Now, my CPU temps are pretty fine (67c during intel stress test with 30+ ambient temp), but my gpu temps are a little too high. It is undervolted to 1V and overclocked to 2000 Mhz on the core and +400Mhz on the memory, it reaches temps of 84c while playing Hellblade and 78c while playing PubG. The top of my case allows 3x120mm fan to be installed or 2x140mm. I was thinking about installing another intake fan on the top front and another exhaust fan on the top rear (either 120mm or 140mm) in order to increase the airflow, but I don't know if that would be useful. Do you guys think this is as good as it can get or should I go ahead and purchase the fans? Also consider that I live in a hot place with no AC and temps go often above 30c during this time of the year.

If your card is this there is nothing wrong with those temps


 

 

That kind of cooling is the worse (you will have high rpm an high temps , anything bellow 90º is ok for that, I understand 85º as max temp you got, normal)

If you want to keep this card put a better cooler , i think that would be the best

or If you have 2 fans on your house spared pick this and put 2 fans (you need to control fans but make a good curve and its ok)

Yes, that's indeed my card. I know the cooler on it isn't the best, I bought it back in February because it was a good deal at the time. I wanted to avoid replacing the cooler or the thermal paste not to void the warranty, so do you think the fans in the case would be completely useless?

i think it has nothing to do with the case , you have airflow for weeks with that case (i've recomended that case to a friend because it has 167 mm cpu clearance and tempered glas + 4 fans seems a great deal)

Maybe if you can remove the psu cover you will have 1-5º better and give enough space on the back of your case to let all the hot air be blown.

With that noctua fan you could buy that 40euro that i've showed you, plus one more for 11-14 euros you will be better than any 1060  

 

The main problem with that card is the heatsink , it seems like old ones , just too little... 1 fan its ok , you only get more noise but that heatsink seems like a old gtx 660    damn palit...

Thank you, I'll see if the psu cover can be removed but I'm pretty sure it is soldered. I should see if I can change just the fan in the gpu cooler but at this point I might just go ahead and get an accelero II since I'd have to void the warranty anyway. Thank you for your tips, very helpful!

Like said above, problem is that your fans are too far from target. You could DIY cardboard tunnel to force air directly to GPU. Also, having tiny mobo on huge case doesn't help.

Almost useless. The problem is the graphics card cooler and not your case fans.
