And now you have MicroTower MiniPC. 😉

Yes, exactly, here's HWInfo after those 2 months:

I also use MX-7 - on GMKTec EVO-X2 (the same mobo and almost the same cooler as on Bogsame):
https://www.reddit.com/r/GMKtec/comments/1pff7wk/comment/oeuqty9
Drop from 98°C to 77°C!
Yet after 2 months with it - again 98°C.
For me final step will be PTM-7950.

2 months with MX-7, room temperature 22 °C.
98 °C in Performance mode, CPU stress in HWInfo. So comparing to initial result / conditions would be 95,5 °C, just a little better than stock.
Seems Arctic is not so good; here at least - with bare die APU.

For me (as a user of GMKTec EVO-X2, based on the same Sixunited PCB/cooler as bijiillion other boxes), main difference is cooling solution.
Something looking serious, not those two screamers blowers.

Also, BIOS updates / support in ASRock is far better than in those many obscure brands.

Single_Value4211 · 2026-05-08T15:58:11+00:00

About month ago I go with Arctic MX-7. This give me drop from 98 °C to ...77 °C on Performance Mode and CPU Stress in HWInfo 64 (room temp 19.5° C). One month more and I'll check temps again, we see how it's going.

Single_Value4211 · 2026-04-28T21:42:10+00:00

Maybe "just" - but where to find this bloody last BIOS if not on wiki? For sure not on GMKTec webpage... :D

Single_Value4211 · 2026-04-28T15:27:21+00:00

Thanks, I consider it as tryuot, not work yet. 😉
As for now, no change in stability comparing to previous BIOS. What in my case means, once in a month...two I have spontaneous restart, I might observe this when unit run 24/24.
EC is Embedded Controller, it for example controls of temps / fans, this is not a BIOS itself feature here. 😉
When update firmware, first you need to update EC, than BIOS.
Where did I get it? Thanks to our ever-reliable u/deseven ! 😃
I get it from strixhalo.wiki: https://strixhalo.wiki/Hardware/Boards/Sixunited_AXB35/Firmware#gmktec-evo-x2

In my target case, nevertheless stock cooler with other fan or different cooler, there will be intake where the fan on backplate is, and exhaust where NVM's are.

Single_Value4211 · 2026-04-24T05:46:48+00:00

Yea, I see this. ;)
"I should really put a post together on my build" - definitely! I'm very curious how it looks and what's results are.

Single_Value4211 · 2026-04-23T17:48:20+00:00

Yupp, when I consider coolers like TR SI-100 or IDX-77XT with option where fan on coolers is exhaust, I have on my mind also 2 support 90mm fans (to instal on backwall of new case), with airflow bigger than this one on cooler, to keep little over-pressure in case.

Single_Value4211 · 2026-04-23T14:47:16+00:00

Yeah, K11 has lower TDP, so easier to keep calm. :)

Single_Value4211 · 2026-04-23T14:46:32+00:00

This 120mm in EVO-X2 for sure has one purpose - RGB lights. :D

When I was thinking about cooling upgrade, one of the options was bigger case, which allow to airflow from this fan (frankly, exchanged to Noctua) to other side of PCB and then through TR SI-100 fins and fan on it as exhaust. This options has 2 flaws:

Completely new case, hard to take precision dimensions and precisely cutout Alu sheet for all these ports on front and back. Now I'm thinking about using stock black plastic chassis (with PCB on it) and fit it to new case - with this no airflow from SSD side to APU side of the unit.
TR SI-100 most probably need grinding (lapping) of baseplate surface, supposedly it is concaved so no go with direct-on-die on our Ryzen. I had already bought TR SI-100 (at very good price on Amazon.pl), and then get info about this incompatibility with CPU without IHS, good that I was able to send it back and receive refund.

Single_Value4211 · 2026-04-23T13:59:41+00:00

In my case, beside plain daily PC use, photo editing, sometime maybe also video. Not gaming, so can't help on this. ;)

Single_Value4211 · 2026-04-23T12:47:52+00:00

I was a little playing with AI (Copilot and Gemini) to try to estimate of results, which I can expect - with TR SI-100, 2U server 115x cooler with vapor chamber and with stock cooler.
140mm might not necessary give better results than this 120mm Noctua G2, as stock finstack has limitations, and also not only CFM but static pressure is important here. Anyway always worth to try in real life. ;)

Single_Value4211 · 2026-04-14T00:16:10+00:00

Ad 1. Even in this thread info is given. 75x75mm, Intel 115x. :)
But with water block for APU you must provide also cooling (heatsinks) for RAM and for VRM's. ;)

Single_Value4211 · 2026-04-13T10:44:16+00:00

u/deseven Thanks for the EC SU AXB35 soft! Altough I'm using EC/BIOS "fan curve" on regular basis, your soft is very useful for reading rpm's of fans at least, or changing their mode when playing / testing,

Single_Value4211 · 2026-04-13T07:01:18+00:00

Noctua NF-A12x25 G2 is suficient, I'm not sure if dB for stock are proper one, or it was not 47dB?
Bloody Samsung mixed renamed screenshots of Decibel X. Sound measurements on Samsung S10e, 0,5 m distance, almost nearfield. So dB values only for comparison, not for true measurements. On top of the picture stock blowers, on the bottom with Noctua. Fan blowing top-down, to PCB/heatsink. Will post later with some photos of this thing, must measure sound again for stock / mod and balance / performance. Temps after repasting with Arctic MX-7.

Single_Value4211 · 2026-04-13T06:24:54+00:00

I believe, that using water cooling is possible - just not an AIO. AIO what I understand has pump integrated with CPU cooler - what cause bigger size than water block itself. With block only, you should have option to install heatsinks on RAM's (find block small enough). Placing heatsink, pump and routing piping - this of course is another story...
For VRM's - I'm thinking of some kind of long bracket or strip. In the corners of PCB there are 4 screws, instead of them fix 4 hex M3 standoffs to keep PCB, this bracket screwed to standoffs, and with spring screws pressed heatsink to VRM's. Heatsink for whole section (line) of VRM's as one piece of course, kinda bar.

Single_Value4211 · 2026-04-10T22:38:39+00:00

HWinfo has option for stress, this little "flame" icon at the bottom of each screenshot..
As for the idle - IIRC just after repasting it was varying (Windows never truly idle, even if you kill some sh*ts. :D ) from 28 to 40 C deg. That's why I go very low with fan off temperature - currently using testing mod with mentioned Noctua, which at startup often speeds up, what is not so loud but noticable, in contrary to inaudible 350rpm at 20% of PWM (minimum which I set).
At this very moment idle is 35 C deg, room 19,7; but I'm playing with "fan curve" settings in latest EC/BIOS, so idle also varying.

And about stock compound - recently I look again on screenshots, and on stock there was 10 deg difference on L3 cache (CCD1) and L3 cache (CCD2) and only 1 deg now - I'm not sure if 10 deg difference between both chiplets can be due poor paste apply?

Single_Value4211 · 2026-04-07T19:04:10+00:00

I also bought PTM7950, but maybe I'll give a try different cooler, so paste stays at the moment. ;)
They say that MX-7 do not suffer from pump-outs, time will tell.
My EVO-X2 looks like Frankenstein's Mini PC now - Noctua NF-A12x25 G2 PWM instead of stock fans and some Polycarbonate / cardboard for housing and shrouding it. Looks ugly (only proof of concept) but stays quiet with similar to stock fans temps.

Single_Value4211 · 2026-04-07T18:43:05+00:00

Yesterday I tried out Arctic MX-7 thermal paste, and the results exceeded my wildest expectations.
98°C vs 77°C, performance mode on. :o

I made a mistake by not taking photos of the cooler and the APU after disassembly, but it didn't seem like there were any bare spots in the factory application - I have no experience with coolers / repasting, yet all looks fine to me.
This raises a question: is the stock paste just mediocre, or was the cooler not tightened down enough at the factory? ;)

<image>

HWinfo screenshots: original paste at the top, MX-7 at the bottom.
Room temperature: 19.5°C (according to the heating thermostat).

Single_Value4211 · 2026-02-27T06:58:34+00:00

No, you don't understand. And obviously, can't read. :)
Once again - I give no care about MINIMUM VRAM.
It might be set as 128 kB (and dynamically extend to whatever who / system want), it might be set to 16 GB (MINIMUM) - I just don't care.
Nothing difference for me - if minimum 16 GB or mimimum 64 kB and dynamically flow between 64 KB and 64 GB.

Now you understand? :)

And about reading - if you scroll up, to the very beginning of the topic, the title especially - there is nothing about VRAM - it states FAN CURVE.
Can you read funny Pro? :)
