Optimal Fan Cooling Set-Up (NEWB)

[zdzilla]

Hey everyone, so I am trying to find the best fan set up for my case. I am very new to PC gaming in general. I have a noctua CPU cooler placed tightly to a noctua fan as an outtake. I am wondering if this even makes sense to have as an outtake fan or if I should place it as another intake fan to the right of the CPU cooler? It would be blowing air towards the tempered glass pane, as I do not have an option to pull from the front. Any suggestions would help, as is my case runs well but wondering if it could run cooler. 

 

Thanks

So the PSU shroud is on top, so that's cut off.  The front has no fans at all?

 

The fans on the bottom... intake I assume?

 

If so, then yes leave the CPU fan to blow into that exhaust fan out the back.

 

What case is that?

(IT would be easier to see if you opened the glass to ditch the reflection)

i think is a roswill.

 

i think you can mount 2 fans on the side.

 

i would do 2 on the side intake 2 on bottom left as intake and back exhaust

Does look like it. I would honestly either leave it stock or do bottom and side in and leave the back open.

For air cooled cards like the 3080, 3080 ti and 3090 having the intake at the bottom and exhausting through the top is the the best since cool air passes over the GPU and hot air does rise if it can.

 

As for the CPU cooler: If the exhaust fan moves less air than the CPU cooler hot air will build up behind it. 

I have the issue with the CM H500 ARGB. When the build had a 2080ti it was not an issue but with a 3080 ti(400 watt stock) it is so I have ordered a Noctua NF-A12x25 to replace the stock fan. I will test without a fan first since that may be the best solution.

You stacked two fans at the exhaust,

That's not good,it creates impedance.

 

Remove the fan from the exhaust of the CPU cooler and see if CPU temps improve.

the gpu air only rises to the top when the exhaust is not doing its job.  the front fans will push the gpu air to the back. the top is for aio only. the slowest fan over comes any benefits from convection.

 

could have had a gpu hot pocket

With the 3080 ti the air between the Noctua dh15 and the exhaust fan(2.5") heats up under load.   

Above the Noctua dh15 is mech so air can escape that way as well but it does not do it fast enough so the dh-15 eventually gets heat soaked along with the GPU.

When I had a 2080 ti and later a 3080 in the case there were no hot spots. 

 

I also have an identical case with a dh-15 but with a FTW3 Ultra 2080 ti and it stays cool.

 

The case will end up with a EVGA XC3 Ultra 3080 ti that is 50 watts cooler than the FTW3 at stock so the problem may just go away. If it doesn't I will add the NF-A12x25.

well in that case it might be needed. what is the case?

It is a CM H500 ARGB. 

I use them for quite productivity builds with air coolers.

The only reason why I am personally using one is that my two gaming computers are connected to OLED TVs and the TVs do burn in doing thinks like forums so I needed a third computer(after I burnt in one of the OLEDs).  The i9 9900k in the CM H500 ARGB was the only computer I had available at the time since is was just off a repair. 

It is on the desk about 2.5' away from me and it is totally quit so I sort of like it.

hmm i no there something up with the 3080 and 3090 cards and temps.  people call me crazy but i see it all the time.

 

well i would tell people to get an bottem intake case but i dont really have proof that it fixes the problem. so i order a 1366 cooler that will fit in my 011 air so i can test botte, front and side intake. the only problem is that the case has no back fan which could be a problem...

I see it as well. 

My 3080 is a ROG Strix OC that has a larger cooler than my MSI and EVGA 3090/3080 ti so it is passable. In a more perfect world I would have gotten all Strix cards but I got what I could get and not what I wanted. 

 

I got luck with the MSI 3090 since it is in a Cooler Master H500M. Now I know the reason why it is still near the top of Gamers Nexus case list.  It is an editing only rig that will never be overclocked so it is the least of my cooling worries.

My MSI Gaming X Trio 3080 ti at stock under load was in the low 80s in my Corsair 5000d but is in the low 70s in a Lian li o11 dynamic so bottom intake is the way to go.

 

I also bought another Lian li o11 dynamic last week for the 5800x and FTW3 Ultra 3080 ti.

The Cooler Master H500P Mesh that the 5800x is in now is at its limits even with an extra 60mm exhaust fan. The extra heat of the FTW3 may turn it into a hot box.  

 

The reason I want the cards to run in the low 70s stock is to have some overclocking headroom. As it is now I have to take off the glass to bench and that is a pain.

ya interesting. i wonder if its the heat or the size of the gpu. longer or wider. you tried removing the pci slot covers?

 

i tryed bidding on a amd 6990 for a poor mans hot gpu its long too but i lost the bit (had a water block too...) but seems like it could have gone like $300+ i only wanted to do $250 + shipping max

 

also was looking for that hot cpu amd 3650 or something? like a 225w cpu but there expensive... so no poor man test haha

 

hmm i think the 30xx gpus have a thicker heat sink? i wounder if they increase the thick ness of the fan or not? kuzz i no that there are problems with thicker cpu coolers and air flow. hmmm

The MSIs are 324mm long, the Strix 319mm and the EVGA 300mm. The EVGA FTW3 2080 ti was 300mm and did not have the issue. 

 

Both the CM H500P and the 5000d had dead air spots that heated up below the GPU. I added 60mm fans on both below the GPU and it worked on the CM but not on the Corsair.

The GPUs are about as thick the the 2080 ti but a little taller.

 

There is also a big difference in vram temps between the 2080 tis and the 3090/3080 ti. 

With the 2080 tis the max overclock temps were around 80c overclocked and in the 60s stock. The backplates were relatively cool.

On the 30 series the stock temps are in the 80s stock and overclocked they are in the low 90s. Air flow across the back plate is a must now.

This is a Rosewill Prism S500 ATX Mid Tower, and a 3060ti.
