[SOLVED] New build and GPU heat problem in NZXT H510i.

[ShavedJesus]

Hello all,

I just made a new build some days ago and I'm having some problems to keep the GPU temperature down while playing.
Here are full specs to start:

• Intel I7-9700K;
• ASUS Turbo GeForce RTX 2070 Super EVO;
• Aorus PRO Gaming WIFI Z390;
• Corsair Hydro H100i Pro;
• 2x8GB Viper 3200MHz;

I want to add also that I tried to change the 2 stock fans with x1 Corsair ML140 Pro (on the top), x1 Corsair ML120 Pro (on the back) both for exausth in order to have negative pressure.
After changing the stock fans I have decreased the CPU temperature about 7-8°, it was around 70 while playing.

So, on idle I have around 27-28° the CPU and 35-36° the GPU.
While playing, the CPU raises to 62-63 now and the GPU, after 10-15 of playing, is always around 80 (max 83) before and after the fans change.

I know that this case is not the best for airflow and I realized that I mounted the fans of Hydro H100i as exausth other than intake... So, I reverted them and, since their CFM was greater than the stock case fans, I changed them, as already mentioned, with the 2 corsair ML1X0 Pro in order to have negative pressure.
The CPU is better now, the GPU no.

Do you have any idea on how to make it better somehow?
Could mounting the GPU as vertical be more efficient in term of airflow?

Thank you very much in advance!

EDIT: For temperatures, I used Apex Legends with all MAX settings as benchmark.

If the GPU is maxing at 80C.....I wouldn't be very concerned as 80C is not really much out of the ordinary. That GPU has a max temp spec of 89C. I'm running two GTX series cards and one RTX and they all run near 80C when maxed out.

You have a blower type cooling on that GPU. It exhausts air to the back and positive case air pressure would give more air to use. As GPU is not in the middle of air flow thru case it's just starving for cool air.
Those single fan GPUs are running pretty hot anyway, if you could place a fan somewhere on the side panel or bottom it would help much more.
You could also put something like this bellow the GPU

I read also this, but I'm wondering if there is any configuration to lower it a bit also because I cannot imagine it in the summer..

Unfortunately my case is not intended for positive pressure and I don't have room for a side fan but the PCI fan that you mentioned could be placed below the GPU. I will think about it, or maybe just buy one to try because, as I said to jay32267, I don't know how it will be in the summer.

Please, let me know if you have any other idea.
Thanks a lot guys.

Here is a picture of the case:

I think I found another solution.
I'm using MSI Afterburner to tweak the GPU fan speed based on temperature. I was able to stay at 74° while playing. Well, it's a bit noisier but I don't care so much about it.
Why does manufacturer keep the GPU fan speed so low? Is it just for the noise like a compromise?

I noticed also that there's a grid below the GPU. I think I'm going to put a dust filter there and maybe 2x 120 intake fans in order to lower the GPU speed fan to save some noise.

What do you think about it?

Thanks a lot.

Yes, manufacturers compromise fan speed for lower sound but also allow for higher temps than users are ready to accept.
That concept of turbine/blower type of cooling is used for simplest cooling on "reference" cards, there are better cooled cards with 2 or more fans and better heat sinks.
Yes, adding one or two fans bellow should considerably help in cooling GPU.
