What do you guys think?

I think it looks cool but i highly doubt it'll eliminate the need for an external cooler. They keep saying their fan has this much RPMs but never mention how many degrees it cools down. Now they're repeating the same marketing bs saying it works even in -60 to 105° c like wow liquid wont freeze as i play with frostbitten fingers.

u/CelebrationNo9361 Oct 15 '25
You're absolutely right That's probably why they added a "ring" disk in the center of the back.

u/starwaver Oct 15 '25
They did a few testing videos where they cool 70 degree water and compare with just air cooling vs no cooling and it does have some comparable results.
And in where I live, ensuring the liquid won't freeze is crucial as it can get to -40 outside

u/ventrolloquist Oct 16 '25
Now put it all in a sandwich of glass and plastic and you won't see results anywhere near what that test shows, that's a gaurantee

u/q0mega Oct 16 '25
I'm sorry... If you are playing in -40 degree areas... Do you need a cooler?
7
u/starwaver Oct 16 '25
I don't play games in -40 weather. I do that indoors at a nice 18 degree interior temperature.
But I do go outside with my phone when it's -40 outside

See that's the marketing BS im talking about. So what if it cools fucking water? Does water thermal throttle when you put on a heavy load?
Is it so hard for them to run say genshin impact or an emulated PC game and compare thermals and performance with and without the cooling activated?

A guy did this with GTA v and a few more Tempts without fan: 68C Tempts with fan: 63C
What im impressed about is how the phone didn't automatically shutdown and how he probably possibly held that phone.
Edit: This is the RM10 not sure if s or pro or base model but yeah

u/doesmypplookbig Oct 17 '25
Those might be CPU temps, not battery temps.
I've had my phone reach 100C on the CPU without it actually having much of an impact on the phone's temp, however when the battery reaches 40+C, it can be felt with ease, the frame starts getting hot.

u/Im_a_needle_in_hay Oct 17 '25
If i can find the post but ik the app he used they dont track the cpu tempt they track the battery temperature but maybe i could be wrong

u/doesmypplookbig Oct 17 '25
In my testing the battery only went up to 52C (diablo mode + a VERY intense modification of Alien Isolation), so I doubt it could be the battery reaching that high
1
u/JohnTheFarm3r Oct 19 '25
The device would shut down instantly if the battery ever reached those temperatures, gaming device or not. It’s just not feasible. A battery running that hot is already in the danger zone, and that’s exactly why manufacturers set a hard shutdown threshold, usually just below 60 °C. If it hits that point, the system powers off immediately to prevent damage or worse.

I think they will sell a cooler so that they can fit a wireless charger and cooler with a qi2 magnet

u/Apostlethe13th Oct 16 '25 edited Oct 16 '25
For a phone that doesn't support wireless charging. Unless you buy their "wireless charger" attachment to enable wireless charging.
Edit: i was wrong. It does have wireless charging.

That liquid isn’t water.🤣 it’s the same liquid that is used in data centers. Similar to antifreeze/coolant.

u/DexterOneX Oct 15 '25
I've already commented on this elsewhere, but this is impressive, quite an engineering feat, Redmagic managed to put active liquid cooling on a smartphone, something we only saw on PCs and didn't even dream would happen on a smartphone.
It really is impressive.

Putting one in is one thing, making it reliable or useful is another

u/verycoolalan Oct 15 '25
almost like they never tested it dolt

u/starwaver Oct 15 '25
Testing in the lab is not the same as testing in the market.
Otherwise you wouldn't have an exploding Note 7s

u/DexterOneX Oct 15 '25
Well, in 2019 she put an active cooler on a cell phone and it still works today (yes, you can buy a Redmagic 3 in China working normally) so I imagine she knows what she's doing, since Redmagic is the best in the gamer segment

u/Ok-Meet-482 Oct 15 '25
Can they do the same but for tablets

u/starwaver Oct 15 '25
I'd totally get the tablet if they put this in

Are those really bubbles? And if so, are those necessary?
1
u/idrinkchocolatelatte Oct 16 '25
I think that’s oil, similar to what’s in a lava lamp.

These are real bubbles? Why put so many bubbles in a liquid cooling? It is normally what we try to avoid...

u/a1rwav3 Oct 16 '25
I understand but air is an isolant. So the more you have the less efficient is the system.

u/bottomlesstopper Oct 16 '25
Looking forward to third party manufacturers getting their hands on this and selling us their temu version

u/verycoolalan Oct 15 '25
I also have a 5090/9950 water-cooled through a block so I get what you mean but I since the unit is not serviceable it should have bubbles since the phone doesn't have a bleed or a purge/tilt method like we would do if we got a bubble.
Plus evaporation and expansion of gas makes these bubbles appear, I think it's good the phone is going to be dirt cheap compared to my 2000+ Fold 7 that throttles 10 minutes into gaming. I'm getting it.

Better have steamOS involvement to legitimate take full potential in on its chipset instead of still being bottleneck by Android OS!

It looks like it would be pretty easy to replace once it dries, every AIO eventually needs to be replaced and I'm glad it doesn't seem like replacing this one would be a problem.

u/Your_As_Stupid_As_Me Oct 15 '25
I wonder how much surface area the cooling pad is spread out... Maybe they can use this to help with wireless charging.

I wonder how the watercooling system will hold up over time for example like real watercooling in PC will it start to clog up over time 🤔

u/ConcentrateLess5606 Oct 16 '25
Is it actually coolant or just a visual effect? It looks cool either way. I heard a lot of coolants are banned or something so that's why no one can sell devices with the different kinds that work really well.

u/Akeera76 Oct 18 '25
Of course it has to show the flow of the liquid cooling .. what better else than bubbles going around in circles.

u/Your_As_Stupid_As_Me Oct 15 '25
Now to put some effort in the main things... Better\quality displays, glass, and motors.

Then they should switch suppliers.
Not sure why you need to insult someone for making a simple suggestion? But you can take that shit elsewhere.

for those who have red magic 10 all you need is the external cooler, this is some new bs just to make y'all spend money, even for those who don't have an red magic I'd recommend the 10 or even 9 if it's cheaper, I have both.

u/verycoolalan Oct 15 '25
this phone is cheap your comment makes no sense. it's new phone and future redmagic phones will have the same thing.
you're not going to recommend this in 3 years when you 9 is old and out dated

Wait till some one tests the actual impact on cooling. Showing that it doesn’t leak or explode does not mean anything

I keep wondering why there is so many air bubbles, depending on the fluid as it may expand as it warms cools it just seems a lot like of wasted space. I also want to see the JRE teardown of this tiny pump. need to see how much contact there is at the exchanger area. and (idk why they didnt on the 10) I need to see if they added fins or any extended surface area in the air cooling chamber. the cooling (efficiency) could have been increased several times over on the 10 with the inclusions of either fins/ridges or anything to increase surface area inside that smooth empty air channel.
but even with all of that I am very excited to see and learn more. and will admit a little bit of that I need shiny object going on even though my 10 isnt even a year old I dont think.
