I have the case from the attached image , Redragon Whelljack it can fit three 120mm fans or two 140mm fans on the front panel (my case) they can be mounted inside or outside considering the glass panel and mesh filter what position would be better ? (Currently getting 74c at 1950mhz@950mv 8000mhz VRAM at my 3060ti under full load and 75c PBO@1.334v full load on my 3700x)

inside mount as air intake closer to gpu the better 3x 120mm
 
ATX, front and bottom are intake, aft and top are exhaust. 140MM fans can run a little quieter than 120 mm while moving the same amount or more air.
 
Naturally RGB 120mm intake fans should be outside mounted for aesthetics.

For performance, inside mounted 120mm intake fans will generate less turbulence since the air from the fan encounters fewer obstacles.
 
So the front is a glass panel? I would install them inside to avoid the fans being too close to the glass and obstruct airflow
 
@joemama the front is of a mesh screen like type, by the looks of it.
 
I currently have them installed like the picture, wondered if moving them inside would improve thermals.
Well i guess the best way to find out is just to move them inside and see.
 
Reporting back GPU Temperatures with the change Superposition 1080p Extreme 1950mhz@950mv 8000mhz RAM at 74c (peak) (no changes) Cinebench R23 12441cb PBO@1.334v at 70c(peak) (5 c drop).
I got a clearance of about 5 centimeters from the intake fans to the gpu. Could turbulence be the reason because GPU temps stayed the same?
 
Well if mounting the fans outside doesn't get obstructed by the glass, then there shouldn't be much difference between installing outside or inside.
I think turbulence is too small of a issue when considering case airflow as it is almost inevitable. The main affecting factors should be how much is the airflow and the path the air flows through.
 
Thats retarded, id remove the glass completely and have the mesh only with fans inside
I Actually tried it no difference whatsoever, perhaps my gpu has shitty dissipation and that's it.
 
OOh i would have so much fun with a dremal on that case ha. It would at least fit 3 140mm fans in the front haha.

Be bye bye glass too, and find some nice open stamped metal to let air flow in, and that PSU cover would have to be altered.

Yes must be the GFX card at fault, sure.

But yeah stupid first build, perhaps i could try to exchange the case for a 4000d airflow or something similar

It's really stupid like the third 120mm fan has to be mounted with water cooler radiator screws if mounted from the inside because it uses screw holes from the non removable hdd cage instead of having it's own for the bottom ones.
 
If possible, leave the glass and remove the mesh.
 
Redone the power cable routing holding the gpu and removed the glass, and runned superposition at same settings again 72c peak yeah really doesn't make much difference.

If you have the opportunity to return this case, do it.

There are a number of thoughtfully designed, relatively attractive mid-tower cases that prioritize proper airflow. The Corsair you mentioned is one.

Here's another one to consider:


I own the Lancool II Mesh Performance and it's very easy to work in, something a novice PC builder will appreciate.

However based on your most recent test with the glass removed, a case with better airflow won't likely improve GPU temperature much further, at least not with your current graphics card.

Can't return it, had it running with a low tdp gpu since 2020 only now i got a higher tdp gpu that i runned into this issues. I considered a swap to the Lancool II Mesh but i been watching stock for months but it nevers come back.Only options in my budget are the Corseir 275r airflow,Cooler Master H500p or the Lian Li Lancool 205.
 
I think front and back it's should be enough

Some people told me that too, well got to find a use for the other two fans.
 
Hi,
Put the extra fans on top as intake.

Stupid question(I might be severely wrong), doesn't hot air go up? Placing them up there wouldn't force the hot air back down again?

Hi,
Only if there is no air to move it otherwise
The back is open for a reason so air can be pushed out
Top if filtered for intake same as front is.
You obviously need another cool air source the front is shit.
