Spoiler: Old Velka Build

Rotating the case (psu bottom) could reduce temp by up to 5C.

Ok, I’ll try, thanks

Hello everyone, I've made a new build

Lovely build!

I might copy most of it soon, have a Velka 3 laying around.

Till now I'm avoiding Flex PSU though, fearing their noise.
How is this one from aliexpress behaving?

Not a lot of customers review to learn something about its quality from the link you posted.
One says the PSU only started once and then nothing. I hope yours is not at risk!
Did it ship with some test report?

My PSU is not loud but not absolutely silent, so I replaced the fan with a Noctua A4x20 FLX. I didn't get any test report, my sample works without any issues.

Thanks a lot for your feedback!

Anything to take care in particular when replacing the fan?

Anything to take care in particular when replacing the fan?

No. You need to take the following steps:
1. Unscrew all the bolts and remove the top cover from PSU.
2. Cut the original fan's cable (with proprietary 2pin).
3. Fix 2pin to A4x20 using OmniJoin™ adaptor set.

Some updates

Today I received a new fan - ID-Cooling NO-9215 RGB. The only one slim 92mm fan with RGB

Noise level (A9-15@50% vs NO-9215@50%) is identical and very low

 

[Moncavo]

Super neat build!!

 

[chinevo]

One more update.

Today I received interesting fan - Scythe Slip Stream Slim 120mm (SY1212SL12M). It‘s super slim, thickness is only 12mm.

The next step is to remove the heatsink from the RAM with a hair dryer.

And yes, it fits! No issues, but super tight - absolutely zero space between RAM, fan and case.

Waiting for L9a Chromax cooler to make some tests.

 

[chinevo]

I have another cooler in my hands - Jonsbo HP-400S

The stock fan has been replaced with an ID-Cooling NO-9215 RGB and tested in Cinebench R23.

The result is the same as Metalfish Z39. 83C after 15 minutes at 50% fan speed. Updated the table in the first post.

Hi there! I apologize in advance for the many questions .
Have you found the voltage and MHz lock at 4.15Ghz and 0.95v stable? Also, any update on the Noctua l9a comparison?
Regarding coolers, have you tried the Z39 cooler? I’ve read it eliminates the turbulence the other coolers have because the fan sits under the heatsink instead of on top of it.
Thanks for sharing your findings!

Nvm about the Z39 lol. I was thinking of comparing the AXP90-X36, the L9a and the Z39 and I meant to ask if you had tested the X36.

Hi.

Yes, I received the L9a a few weeks ago and tested it. The temperature was the same as the Z39 and Jonsbo HP-400S. I think the main limitation is the fan and its speed (50%). It can blow out a certain amount of hot air. That's why all three coolers have the same result. As for the AXP90-X36, I haven't tried it. But I'm sure I'll get the same 83+-1C

Regarding voltage and MHz. I set offset to -0.2625V in bios. And didn't do any more settings. The voltage became about 0.95V. The frequency is floating. In Cinebench it is 4.1-4.15, in games 4.15-4.25. The system is stable.

Thank you very much for getting back to me! The reason I was comparing the l9a, the axp90-x36 and the Z39 is because they differ a bit in design. The l9a is the legend, so it has to be good, the axp90-x36's heatsink has a vertical fin design instead of the horizontal design of the l9a so air probably has a better chance of escaping and not be blocked by the RAM and rear mobo ports, especially in sandwich cases where you don't have anything above or below the motherboard, so my thought was that while it probably has similar cooling performance, the other components might remain cooler unaffected by the warm air of the CPU.
The Z39 sounds very interesting because it would eliminate the turbulence that the other 2 have in a Velka 3 and I assume Velka 5 case too since it has more room to pull air from underneath the heatsink. So the Z39 is probably the quietest of the bunch from 70% fan speed on wards.
Those are some very good voltages the 5800X3D has! Better than the normal 5800X. Thanks!

Ok, I’ll try, thanks

Did you verify this?

 

[chinevo]

Did you verify this?

Yes, I tried, no difference.

 

[BruvAL]

I see you have a 5800x3d

Should i go with this cpu and undervolt or just get a lower tdp cpu
Are you still seeing higher frames compared to a 5600x or something?

Thanks,

I replaced 5800x3D with 7600X and plan to upgrade to 7800X3D.
X3D is a big deal if you prefer to play at 1080p at high refresh rates (144-360Hz). My case: Valorant and Zowie XL2566K (360Hz).

I lowered the voltage on my 5800X3D with a PBO2 tuner (-30mV curve) and got a maximum of 75C in games.

How are the temps with the ryzen 7000 series cpu in your velka?
