@Krit
You are right 0.0 why the heck I thought that it is spitting hot air in the back, not the front -.-
I think spider needs to get in the pack inside the case :).

Wall also is the problem for front fans. Front and exhaust needs space for breathing.
 
Very nice build! I'm still trying to figure out how you managed to make the fan hold there! You have a very great magic trick!
The water cooling hoses and the RAM fan stand are above the fan and are squeezing it weakly so it can't move.

Yeah, wise, otherwise it might help in recirculating PSU hot air by the right 12cm fan.

Best approach will be to turn the PSU to exhaust in the back but maybe is not enough clearance for cables than.

It's ok to be like that, cause the psu has 1kW, and overall system powerdraw is around 400-500W. So even with this setup psu should not fry itself.

I was not worrying about your PSU health but, on 40- 50 % load PSU will exhaust hot air very close to the the bottom fans intake, hot air of PSU being recirculated by your bottom case fans.

Another thing to test :), I will test with carboard to close the gap between psu, and fans chambers.
I will need a lot of cardboard :D.
 
I think that the problem here:
1748435632239.jpeg

It's not the PSU, but if I see correctly, there are 4 input and one output fans. So air comes out from where it can, but manages not to follow the best direction.
A few degrees coming from the PSU is not a problem, but is the air cooling the video card or swirling the warm air around it.
 
Noob me, i thought that undervolting was going to lower my ram temps. I have to setup a fancurve to see if that helps to bring my temps lower than 84c actual to 80c or below.

Then i will be trying a safe undervolt that works with most of my games.

Is that unsafe those 84~86c temps on the ram???IMG_1298.jpeg
 
@jormungand

It's not unsafe, it is even within specification, but we are strange ppl who don't like high temperatures, and if I think correctly UV is for gaining speed on the gpu die, and lower temps there, it has little to do with vram. (little cause if the die is colder, than all of the components are colder too, heat transfer by proximity.)
Which model do You have?
And about fan curve in gpu, the fan is working in tandem with gpu die temperature, so even if You UV Your card, cause of the lower die temp fan will spin slower, and vram could get hotter cause of that.
In My opinion it is better to set gpu fan curve to maximaze the fan speeds that don't annoy You :).

The asus prime oc 9070xt, im gonna work on that fan curve too, im not that annoyed by fan noise since my case fans are loud already

That's lower than average. It's not unsafe it's good. VRAM was designed to run at ~90C without any problems whatsoever.

I would crank up fan speed to see if it helps with vram. Cause 1000 rpm is really slow for gpu in My opinion.

Like that was an undervolted i believe its related to what you said of die-fan curve temps relation. Look at the watts. I was just doing try outs yesterday with monster hunter wilds benchmark.

Oh i forgot im using the performance bios not the quiet one. Just for info

221 is really low, but the clocks are low as well. but I love the delta temp of Your gpu die, in My case 30C is "normal", You 've got 15C.
About bios, I did not even tried the quiet one, casue almost all gpus 9070 and xt are strangely really set to be quiet even with performance bios.

In adrenaline You can set custom fan curve, and I personally hate 0fan rpm, cause in browsing internet without fan spin gpu vram is sitting 60-64. but with lowest fan speed it is 50-52C.
I would set for fans to spin at max rpm that is comfortable for You when gpu hits 70C. (i think that gpu with 100% load will be always hotter than 70C :). )
Ps windows 11 has quite great screenshot menu, You can even select what You want to take screenshot of :).


TEST TIME
Ok another day another test :), setup was 40% on case fans, 30% on cpu, 45% on gpu.
I've added fan to direct airflow to cpu cooler outside the case. (3x120 and 3x140)
Changed the direction of airflow completely

Capture039.webpCapture041.jpgCapture040.jpg

Temperatures where oscilating between 79-81 on vram through run, and max hotspot was 80C, and cpu was max 50C, but normally around 38-45C.
Conclusion this setup is strange but gives results that are combining best from yesterdays tests.
But it is not apples to apples, cause of adding one more fan.
about psu and hot air from it, it has narrow gap around 4mm wide, so it shouldn't interferate that much with gpu :).
I just don't know why even with lower temps gpu is not boosting like yesterday. maybe to much in background that was getting readings.

I think your fans positioning are optimal like that. I'd keep them in the same place, but I'd also flip them all to have airflow reversed. You're going to dust your PC real quick if you keep it this way.

The top one: Intake
The 2 front: Intake
The 2 on the CPU: toward exhaust
The one on the back: exhaust

I like to have positive pressure with only 1 exhaust that I make spin faster than the intakes. For example, my intakes are arround 800rpm, but my lone exhaust is around 1000 to 1200rpm

I also opened my exhaust vent, but this is just me being a bit :kookoo:

And I also keep the PC sideways! :kookoo::D

After I bought 9070 xt my pc was finally able to stand, nearly 2 years it was on side cause it's easier to tinker with it like that :)

also opened my exhaust vent, but this is just me being a bit :kookoo:
Nah, I've already drilled a hole in 5 days case cause the cable support was designed bad :)
It's normal :D
I think i will add exhaust to Heat Windows in gpu that is connected with top fan.
 
i got home and jumped really quick to check if there's a change with fan curve

Stock setting with fan curve from msi afterburner
IDK if i went too aggressive :roll:

update.

second run
Voltage offset -80
power limit -20

gpu 52c
hotspot 69-70c
Mem 76-78c
Fan speed 60%~61%
253w

no frames lost.

now i need to refine all that crap this weekend .

I didn't OC the memory, i feel like if im not losing performance my goal is mainly temps and efficiency.

I need to make a run in CP2077 later and ill post the results

Temps are great. :) You've got the same resolution as I :D
And now I'm curious if with UV and PL I could achieve temps like yours :p
Maybe not fan speeds, cause Gigabyte tend to be irritating over 50% pwm. 40-45 is limit for me. :rolleyes:
 
Conclusion, With front fans OFF gpu could achieve around 3200MHz boost clock, but cpu was sitting 62C,

Max values tell you nothing for frequency, use avg.

I would like to apologize as I'm still learning how to do valid results, but I think I will be doing spreadsheet from the benchmarks :). Cause the data in diagrams is not as detailed as raw data :D.
And every critique is welcomed :), (constructive critique is essential for growth :D )

I mean you gotta look at the numbers to see that setup 1 only achieved one thing - failed to provide enough fresh air for the CPU. GPU temps between both setups are nearly identical.

That's why in Yesterdays test I've added hw info from around the test (but it is still not enough cause it has few seconds before the test, and after). So raw data and analyzing it is needed here :).
Edit, are the stats from hw info and techpowerup gpuz the same? or better to log both of them and compare?

Seems the Adrenaline and the drivers in this video
about 32: mark, he talks about patterns in boost algorithms.
I guess you need to learn the behavior and steps in boost of your particular card.
Hope it helps

Fractal had good grills, oh well you did it already:D, mine was really bad, far from Fractal that why I cut it off.
By keeping it in that position the case not sure will really benefit the GPU
