GPU temps and how to low down the noise in PO3 630

Simplerider1984

Hi!

I was hoping to have pretty quite PC. PO3 630

I've instaled noctune to reduce CPU noise but now GPU is a pain.

In games i get 80* - is this normal?

GPU creates a lot of noise, any ideas how to reduce?

I take you have RTX 3070, right? Temps are normal, but admittedly the GPU makes a lot of noise. You should be able to lower the temps and noise with MSI Afterburner. Youtube has many videos how to do this. Look for undervolting.

More drastic step would be to deshround the card and replace those original fans with something better (92mm). Below is one thread where this is discussed. I've done this with 1080Ti and 3080Ti with very good results.

Below are few pics what to expect if you open the card. Nothing to worry about as it is very simple operation to do.

Thank you Sir for helping me out.

My GPU is 3060… i do belive is quite simillar to the 3070.

I would definitly go for a fan swap. The question now is which one should i buy? which one fits?

thank you so much

Cheers!

I believe that 3060 and 3070 are basically similar in construction. Remove the shourd and take a peek. Pay attention to how the original fans are powered - single connector or two?

If you are happy with using zip ties, you can get normal 92mm wide and 25mm thick fans. It has been a few years since I had 3070 card, but I believe I used two slimmer 14mm Noctua NF-A9x14 PWM fans. I powered them directly from the aftermarket MSI motherboard I was using. You don't have to get Noctua fans, but there are many as good and cheap options out there. Some are even black or white, if that is what you prefer.

Since you are using Acer motherboard that has limited number of fan connectors, you may have to use Y-splitter cable (attaching two fans into one cable) and modify the connector that attaches to the card itself. This would mean splicing cables and maybe even some soldering, but any electrician should be able to make you a new connector if needed at a cost of a cup of coffee.

Good luck!

One more thing!

When you take out that GPU, remember to open the plastic PCIE latch before pulling the card out. It is at the end of the PCIE connector and anchors the card in place.

A friend of mine ripped out the whole PCIE connector from the Acer PO3-620 motherboard because he left it locked. (True story.)

Sheesh, he must have really strong arms. :)

Not really. He's tall and skinny guy with long limbs.

Since the lock at the end was still closed but there was some give (he had removed the screws), he kept rocking the card up and down while applying more and more force until the PCIe connector finnally gave up.
