By the way there are also programs that give you more options and where you can set a desired temperatures which the CPU won’t go over such as “Ryzen Controller” (deprecated but still working fine) or the new and advanced “Universal x86 Tuning Utility”.
I will keep it connected to the motherboard as temperatures are not so bad, it keeps under 70ºC all the time with medium loads. The fan brings an adapter to an USB port and I have also tested it but it works at max speeds and it is a bit noisy.
I have checked apps to control the fan by software but this apps doesnt find the CPU (another stone in the path… I don’t think I will buy a chuwi computer again). I have tried Aida64 and HWInfo and they doesn’t see the CPU fan neither.
Any other idea would be really appreciated!!!
70ºC is very good all considering!
Yeah, I don’t think Chuwi realizes that on the long run their unsupportive policy will bite them in the ass, it’s good if you want to make a quick buck, but as more people will realize their doings (or lack of) more will stop buying or recommend their products…which is a pity.
I haven’t tried it yet, but check and see if the free program “FanControl” can help you. I heard very good things about it:

I have tried FanControl but it doesn’t find any fan neither, it seems fans are controlled by firmware and hidden for Windows.

Dammit! 
The reasons behind these technical choices are incomprehensible to me. 
Hi
I wondered if anyone has anyone tried ducting the fan to the air vent or perhaps adding heat pipes to the heat sink (not sure where they would go exactly)
I bought the 5800h one of these new as was going cheap.
Some of the low profile cooler options look like they might perhaps fit (in height) and these are rate he much higher TDP
Sorry if this is a lot of questions
This is exactly what I’m going to do once the Two year warranty period expires. I’m going to add heat pipes to the original heat sink, can’t do it sooner since the warranty gets voided and I’m not trusting this thing not to have problems in these two years.
What I was thinking to do instead was using another heatsink (or creat my own), and just switch back to the original heatsink if I had to send the unit for warranty…but I’m kinda lazy now so I might not do it 
Thanks for the reply, really appreciated 
I turned it on for the first time today, was on for about 45min.
The fan didn’t seem to spin as all and for a few minutes I thought of the post about disconnected fan header.
Then it sporadically span up slowly now and then still barely noticeable, after 30 min of doing very little just web browsing and downloading some software it just span up like a hair dryer for about 2min, then back to normal.
The fan looks to be 50mm, so the poor fan curve and half sized fan add to the heat pipe issue already covered.
I didn’t get any temperature readings
The ducting was my lazy idea as I see others getting 5 degree drops in different systems.
It would be nice if we knew the make of cooler or mother board to try and sorce something elsewhere. Or if its all in house stuff they could send the tech drawings.
I see some laptops have a three screw coolers, would be nice to find something which could be modified etc
If chuwi are reading, please feel free to upload something as several people would be grateful
I’m not sure what you mean. Have you already made the change? Could you please post a picture of your mod? Or do you still have to do it?
We need a better cooler.
Since I purchased the RZBox I have only used It at 25W with boosting disabled, because at more power the CPU hit 100°C in seconds.
I have reapplied thermal paste several times and removed the side panel and put a 140mm fan, but the main fault is the stock CPU cooler with its single heatpipe and low fin count.
WE NEED THE FULL POTENTIAL OF THIS PC.
Hi
I’ve come across these a 36mm and 30mm cooler
Would be interested in the opinions of anyone who had changed or looked at their coolers to see if these would work
I know a 5v fan would need to be sourced etc
Thanks
Stu
Just wanted to add that if these are a good fit (I don’t know if these are, for sure they’ll need some adjusting) you have to at least drill the top of the panel as the hot air must be expelled to the outside, you can’t just slap these on
Good point, was thinking of replacing the rear panel with dust cover mesh
I’ve added 1.75mm of thermal pad to the aluminium to try and absorb some more heat
(Seen it on YouTube with laptops)
Also added two 35 x 35 x 11mm copper heatsinks to the front fan section.
In CPUz stress test, it hits temp of 97 rather than 100 straight away. Then after another 20 to seconds we’re back at 100.
So looks to have done something, but nothing worthwhile I’m afraid.
Hi Oskarcanyon,
Looks good, did you get any good results.
I noticed mine is set to 54w TDP out of the box
So I’ve dropped it to the 45w which I believe was what the stock should be
Haven’t had any time to test but hopefully that will help a little.
Thanks
Stu
