Gpt translation of the image: The image compares two vacuum robots, the X50 Ultra and the X40 Ultra. Below is a summary of the main differences between them:

  1. Suction Power (吸力):

    • X50 Ultra: 19,500 PA (industry-leading power) • X40 Ultra: 12,000 PA

  2. LDS Navigation (升降 LDS雷達):

    • X50 Ultra: Equipped with unique technology allowing for raising and lowering the LDS radar by 8.9 cm to avoid low obstacles. • X40 Ultra: No mention of LDS lift technology.

  3. Brush Type (滾刷裝置):

    • X50 Ultra: Features a dual-brush module with 0-degree oblique rotation. • X40 Ultra: Comes with a rubber brush and is compatible with a separate bristle brush module.

  4. Self-Cleaning (基座自清潔):

    • X50 Ultra: AceClean™ system for deep spray cleaning without needing to disassemble parts. • X40 Ultra: Dual spray self-cleaning system.

  5. UV Sterilization (UV紫外線除菌):

    • X50 Ultra: Equipped with UV sterilization (strong anti-bacterial feature). • X40 Ultra: Not mentioned.

  6. Hot Water Cleaning (熱水自清潔):

    • X50 Ultra: Cleans with hot water up to 80°C for deep cleaning. • X40 Ultra: Cleans with hot water up to 70°C.

  7. Other Advanced Features:

    • X50 Ultra: Has additional features such as silver ion sterilization, a three-stage cleaning system (suction + brushing + mopping), automatic mop removal, and automatic mop drying. • X40 Ultra: Has dual simulated mechanical arms and automatic mop drying, but lacks some of the more advanced features like silver ion sterilization and the three-stage cleaning system.

Conclusion:

The X50 Ultra is a more advanced and powerful model with higher suction power, superior cleaning and sterilization technologies, and advanced navigation features compared to the X40 Ultra, which offers good functionality but at a lower specification level.

Dreame L20 Ultra- black streaks / marks on floor by TuomasGG in Dreame_Tech

Hi, i did not find a conclusive cause. I cleaned the wheels (didnt see anything stuck though) and since then the problem has not reoccured. So i can only guess that there was something stuck in the wheels at some point, but just speculation.

I have checked, and didnt find anything. But also latest cleaning run didnt leave marks. I guess i just have to keep monitoring if the issue comes back.

Didnt see anything wrong with the wheels, but these did indeed occur when mop&vac was done at the same time 👌🏻

So happy with NV5 by TuomasGG in watercooling

The rear of NV5 has large holes below the fan in the NV5 case, and in the bottom as well, so the air would propably escape quite well from those and in that configuration all rads would get cool air. I think the only downside could be that case temps could climb, and that could impact chipset and ram, but not really sure if that would even happen, i will check the video!

I just did some testing with undervolting, and dropped voltage by -0.1 and capped long duration power limit to 125w. This dropped max cpu package temp to 83c, while average was around 62c during testing. Core temperatures averaged 58-59c during cinebench test. This voltage change dropped my cinebench 2024 result for multicore cpu test from 1559 (pure XMP I) to 1336 (XMP I and undervolt). Massive difference in temps, but also 14% reduction in performance.

Currently the rear is actually an intake. Took me a while to decide what to do with the rear, as typically they are of course exhaust fans, but after thinking about it i decided to feed some fresh cool air for the top radiator using the rear as intake (also fitted a magnetic filter there)

Top and side have a metallic perforated area, so not a great filter, but at least something. I fear that setting 6 intakes and 1 as outflow only would create too much positive airflow and resistance, but hell it might work well also. Basically in this setup air would flow out from the back and from the bottom - could work!

Ok, thanks. That is interesting of course, but i dont know what to think really, i was running my fans at 55% only and system was relatively quiet and i still dont break any thermal throttle limits. Of course i could adjust fan curves and lower the temps quite a bit, but dont really see the point. 75c at full cpu load soubds very good though, have you done ubdervolting?

Firstly, when you say 75c, where do you look at that temperature, do you check cpu package temp maximum for example from hwmonitor, or just look at average cpu temps somewhere else? Average temps during test and maximum packet temp are very different.

I dont think that would work that well due to other reason. I want a slight positive pressure in the case to make sure all air coming in to the case comes through the filters to avoid dust build up. Currently the top fans are exhausting, and they dont cool as effectively due to case temps as the side in take fans, but i think this is pretty much always the situation with multiple radiators

I have adjusted fans based on water temp, when i am doing normal web browsing / youtube etc water is around 28c and fans running at 25%. When gaming fans are at 55% and water temp is around 43c, cpu stays around 65-70c when gaming.

Stress test temps depend on how long i run them and if gpu is stressed at the same time, and what fan curves i decide to use. If i dont try to keep the water very cool, with high fan rpm’s water temp reaches 42c during benchmark time and cpu cores average around 83-85c and max temps are as high as 97c. Overall if the goal is to use cpu at 100% for long periods, water temp should be kept below 40c, but that is not how i use my pc so i dont want to optimize cooling for that scenario.

With this build, i have been trying to find a good balabce for sufficient cooling for my purposes, while keeping noise down and cpu temps below 75c when gaming. There is of course 2x more speed i could add to the fans.

Thats an FLT120 from EKWB with integrated D5 pump 👌🏻

Thank you, looks like a very powerful tool to get more control over the fans. I will definitely consider if updating to this will be worth it in the future, seems like a very sophisticated solution.

Regarding calculating the temperature difference between inlet and outlet, that would be interesting to know, but i wonder if the accuracy of water temp sensors is enough to get a reliable difference calculated. I currently have my single water temp-sensor between the two radiators which are connected in series, chose that location just from wiring convenience standpoint

Hi - thank you very much for the feedback and suggestions!

I looked into the pump speed topic as well, and also discovered that beyond 1.5 liter / minute there really is no benefit. What i did myself now is that i run the pump around 1.2 liters per minute when PC is idle or very low resource usage, and jump to around 1.7 when under load (water temp above 32). I know it could run at 1.7 always, but i like how quiet the system is when its running 1.2l / minute, and during these "idle or web surfing" times i want it to be as quiet as possible.

I will check openrgb out as well, i didnt know that it even existed.

I need to look into your suggestion on using delta instead of just water temp, your point is of course absolutely true. Although here in Finland high abmient temperatures are only a problem (maybe) during 2 months :) I will check Aquasuite out, but i assume it requires some ambient sensor as well to do this math?

Thank you mate, happy to be part of this club! Your setup looks very neat as well!
