So is this aero cooling fan really works? Or just another gimmick? Anyone can confirm that the temp is much better with the fan Acc on? Thanks

I don't have the phone yet, but all the reviews have said it does make a difference in long term performance. I think it's supposed to keep things about 5°C cooler and reduces/eliminates thermal throttling. Doesn't sound gimmicky to me.
In the reviews that I have seen, that showed the backside of the cooling fan, it doesn't look like there is actually any ports that directly interface with the unit itself. But rather, from what I have read, it keeps your hands cooler and not as sweaty. So, maybe that is where the 5 degree difference comes in. If your hands are cooler and not transferring heat to the unit, then that would make sense why it would help keep it cooler by 5 degrees.

Yeah, it's the surface temp that goes down 5°C, not internal. I haven't seen any tests on internal temps, but several reviews have shown a definite increase in the amount of time before thermal throttling kicked in, and not at all in some cases.

I read somewhere the tested temp drop with the cooling fan was something like 5C to 10C on the back of the phone and 2C to 4C internal temp drop.
Allright thanks a lot guys. Maybe I'll be getting the Acc after all.
This Active cooling fan doesn't drain much battery, it's like you don't have it at all.
It's surprisingly lightweight, it doesn't make the phone heavier at all.
It comes with adhesive hard-rubber cushions you can put under it, to make the phone stand alone, just like having a pair of shoes on its feet.
The writing "Republic of gamers" on is is also RGB-backlighted, and it's really bright!
The cooling stand extends itself for half centimeter, so you can attach it easily on the phone.
And it does the job! Also, keeping your fingers refreshed, neither too much nor too little, so they won't sweat.
Above all, keeps the phone cooled enough. A must have accessory, for Asus ROG Phone 2!
I love the aero cooler, it works and cools your fingers at the same time.

Hey guys. the top corner on the back o my tab gets extremely hot while the screen is on. like Very hot, on the back about an inch and 1/2 below the volume rocker. is this a known issue or should i take it back to bestbuy and get it exchanged?
Please use the Q&A Forum for questions Thanks

Thats where the processor is. Are you overclocked? Mine gets warm, but I believe that's because I have it in a case and there is no room for heat dissipation. Heat will kill electronics, so make sure that it does not get too hot.

Unfortunately this is just another consumer with his or her mind poisoned by companies who sell worthless cooling products for electronic devices.
It requires an education in electrical engineering to understand what is "hot". You cant simply feel the back of your device and guess that it is hot when you have no idea what the temperature even is and when you have no idea what temperature is hot for electronics.
Chips can run at 80c which is getting close to water boiling. If the back of your device does not burn your skin to a blister then NO, your device is not running hot or anywhere near warm.
Education is key to understanding our reality.

As stated before, the tegra 2 does not produce anywhere near the power dissipation to overheat even when overclocked.
I have to ask again, what is the temperature of the back of the unit?

how would i know what the temp. is?
It seems as if there is a bad design flaw in the battery compartment on this phone. Whatever is behind the battery next to the sim gets really hot and transfers heat into the battery(Not a good idea if you read up on batteries)
Im trying to put a spacer between there so it does not get in direct contact with the battery. We will see how it goes. IF not, They will be sending me a different phone.
Heck, my Rezound got above 140 degrees in my first unit, Verizon told me the battery was still good and to use it when I got a CLN replacement.
Some of the battery's red paint is now on the new unit's door, got a bunch of silver lines showing on the pack from all the heat stress its been through
yea thats what happen to my other batt...Try putting some paper under the battery so that it dont touch the hot parts where the sim is...the phone seems MUCH cooler now to me that way...if this is the problem I am gonna demand something else from verizon
None of them were 3.8v btw....its a spacing issue between the hot stuff and the battery guys....I can confirm it now...my battery hasnt got over 37.3 when charging now....its running so much cooler to the touch even now. .....hmmmm htc.....Id rather have a brick of a phone than a overheater soldering iron phone
now in at 36c while charging...its cooling down! yay
Yay now 35c......hmmmmmmmm weird isnt it?
maybe they should vent the back....i just cut a square hold around it so the battery can breathe and now the temps seem even better....will report back

If you guys are looking for a good material to use, the paper-gasket material for making your own gaskets (for automotive use) is pretty good at insulating from heat.

But that heat has to go somewhere, no? I mean, it sucks that it's going into the battery, but could you potentially damage something else by bottling up that heat? It's probably nowhere near enough heat to damage the CPU, I suppose.
This isnt my problem or any other users...we shouldn't have to do anything to a product that is supposed to work.....Ive been noticing though that the phone has been dying quicker since its been getting hotter outside....but that gasket material is a good idea
i'm having trouble visualizing this... pics?
You are just putting some kind of material under the battery and just mashing the battery in hard so it still fits, but now has a little bit of insulation?
but you dont put heat into lion batteries...as they heat up they self discharge really fast....after an hour of leaving it there now im only at 94 percent...and I can promise you its lasting a lot longer now and running a ton cooler....I think the reason the extended battery lasts so much longer is because it has more metal to heat up than the regular batt does.....Im seriously about to class action lawsuit vzw and htc for selling such a badly designed product....good brains and beauty but the design of the battery is horrid
and yes just a little bit of something under the battery to give it insulation will do the trick

It gets warm because it is a quadcore, plus when installing a bunch of things on the phone it will heat up. The memory is nothing to worry about, Android handles memory differently than most OSes. On my One X+ the speaker is pretty loud, it could be your case muffling it.

Android uses ram in a totally different way to windows and ios. Android is designed to think as unused ram as useless ram, And it will manage background processes on it's own. A google search will provide more information on how android uses ram.

I've ripped it apart a few times, no fin, but there is enough clearance to do so, I might give that a shot just because.
Not sure of the potential interference to cell signal though..
Good idea regardless, even aluminum foil at that close proximity with maybe thermal compound or a pad would do more than nothing, in theory.

(edit - all that tape covers areas i didn't want to short, antenna connections mostly. )
View attachment 2220069
So I actually went for it. This is 8 layers of aluminum foil stacked, by folding on of the precut sheets on top of itself until it almost exactly matched the internal dimensions of the LGOG.
This picture is slightly dated, The red+blue borderd box indicates more material I had removed and is no longer present in the rear cover of the phone. The WiFi antenna is located in the backplate for our phone, I thought it wouldn't be affected by the foil but there were two seperate issues.
1.) The contacts themselves didn't always make contact, effectively leaving no antenna.
2.) wireless signal sucked
Also, directly under that area on the opposide side of our mainboard is the LTE antenna. Again *should* is the key work that in theory it would run with no issues, able to radiate out the front of the device.
1.) LTE signal was dramatically impacted. Disabling LTE and using 4g showed fantastic signal. So if you don't use LTE or have LTE in your area this foil can stay, maybe increase the cutout around the contacts so WIFI antenna reattaches correctly.
Also note the cutout area on the bottom. That is our main antenna block attached to the speaker.
1.) Every part of the antenna areas has to be taped to try and use this area.
2.) Foil by itself with no thermal interface material is very unlikely to be sponging or collecting any heat at this relative distance from the hotspots anyway.
3.) Overall signal sucked, not worth it.
Take note of the two metal shims on the top and right of the battery. There is an almost entirely metal "basket" that houses every bit of our phone on the front side.
1.) This is in place to transfer some of the heat that the foil picks up from the transceiver module (metallic thing that is NOT taped over above the top right corner of the battery)
2.) This yeilds a very nice increase in thermal "density" overall. It is a much increased area over which has to heat to reach thermal equilibrium.
In the end I've been running this for about a week now. Placebo effect over and done, testing here and there and I can report.
It makes a dramatic impact on overall temperature regulation of the phone. It does not completely eliminate the hotspot on the back but it does spread it very effectively.
The phone can still reach "thermal saturation" as it were, and will given enough time. There is a weird tradeoff now involved, and I'd have to go back and test this separate to draw any definite conclusions, thusly;
1. You now have more material that can eventually heat up to the point where the phone throttles, this naturally takes much longer to occur (which is good)
however, in theory, this added material still has to find a way to radiate its heat, which might take LONGER to do so.
However, however: ..You also have a greatly increased the surface area that this material can dissipate heat over, so it could take LESS time.
Needs to be tested, but subjectively I can say it is better overall.
Most dramatic increases I get for my personal use case that made this worth it,
repeated restarts from multiple flashes and validating startup tweaks, voltage settings, governer advanced settings properly all taking and setting, etc. Much cooler overall, verified by constantly checking CPU and Battery temps during and after.
Running the phone on LTE, with bluetooth and GPS on, while actively navigating with maps, while actively streaming audio to my car stereo via bluetooth, while hooked up to car charger.
Does NOT hit the point where the screen is impossibly dim and refuses to charge because of how hot the phone gets doing this.
If you've used your LGOG as navigation while docked to a stand on your dash you know exactly how hot this phone can get. It also cools itself insanely faster after this.
Ultimate tradeoff: I have slightly less signal for LTE overall, and it's very slight. I could continue customizing my cutout, and will eventually, but this is working very well for now. It's almost much cleaner than the picture indicates, as once I finalized what worked I trimmed all the edges and cutouts around the backplate fasteners, etc.
Good luck and have fun if you're feeling adventurous.

You must live with spotty lte service. I get plenty of battery on lte with excellent signal strength. Your drain likely stems from frequently switching between lte and hspa

Hello Android Radio friends,
I have thought a lot about how to solve the problem of overheating Android devices with PX5 and PX6 processors. Next summer will come for sure.
My specially designed passive heat sinks are probably known by some people.
This time, I'm going to focus on active cooling + heatsink.
It was important that as many people as possible can use this method. It should be as easy as possible to install, even by people who have no manual skills.
Therefore I created 3D models of different top covers which you can easily print out if you have a 3D printer.
In this lid there are already the drillings for mounting a fan. I make the whole project available for the community on Thingiverse. I also add number 1 - 22 to each 3D model. If someone doesn't find the 3D model for his own top cover. Tell me the dimensions. I will create the 3d model. Let's make a collection of compatible devices.
Because high temperatures can occur in a car in summer, I used ABS as material. This can withstand temperatures up to 100°C.
Of course you could also drill a big hole in the top cover. But it does not look so nice. ?
If someone doesn't have a 3D printer. There are many different websites that offer 3D printing at low prices.
In the video I also show some used fans and some methods of power supply.

What do you think of this project?
Alex
Update 10.07.2020
Meanwhile there are 22 different 3D models.
Nice ideas.
Had some thoughts about that first minute I unpacked radio upgrade for my car, PX6 unit. It has some perforations on the back but it is all closed underneath with plastic so I think almost no air circulation happens there. Yeah it is 2DIN with aluminium heatsink on the back, and yes in my car ventilation is right above it but - I don't like it. Maybe some holes could help.
I'm writing this because of an experience with completely different thing, had annoying fan noise on an instrument amplifier, which was at 100% all the time. No matter how it was used or maybe unused at the time, noise was unbearable. Manual control is too dangerous because I know sooner or later I would forget to turn it up when needed, but it can be automatic so quick and nice fix was temperature control board: https://www.aliexpress.com/item/32886053224.html . I think it could work nice for projects like yours :good:

simply useless. If you switch stock thermal pad with a better quality one and install a good heatsink all is done. I did it one year ago and nothing more is necessary.
Consider that PX5 is a 5W SoC so a passive cooling is more than sufficient to remove heat

Yes, I performed a torture test and SoC temperature during this test was between 70-80°C (never reached during normal use). So as I stated before: a 5W SoC can easily be cooled passively. If you want to increase noise, failure probability of the fan and dust inside the radio, you can but it's not necessary at all. I have experience in cooling CPUs (also with massive overclock) for decades, this is not my first experience.
Moreover my radio is working passively since last year and I've nevere experienced stuttering or problems due to heat.
Other parts of the radio are not hot at all.
Awesome job Alex, and great video. Comprehensive tests too. Thanks so much for your hard work

70 to 80°C under which conditions?
What outside temperature?
Device 1Din or 2Din?
Cover open or closed?
Air conditioning on?
The advantage of active cooling is that not only the CPU is cooled, but also all other components such as voltage regulators, capacitors, amplifier chip and other microchips.
And if the 5€ fan should break after years, it's still better than if a 300€+ device breaks down.

I tested a lot with and without heat sink and fan, same as you did.
By the way... Thanks a lot for providing the 3-D-images to print the top cover. :highfive:
I printed the top cover for my head units to be used with a 80mm "be quiet" fan, which is really not audible if the unit is mounted in the dash board. Even on bench test the fan is really quiet.
The CPU temperature of all my 2-DIN units got down from (in Throttling Test) ~95°C down to max 48°C. Throttling was a real an issue. Up to 55% throttling without cooling down.
With normal usage (navigation with active route guidance, some Tasker tasks in background working, audio decoding active) the CPU is cooled down from nearly 80°C to ~30°C at ~25°C outside temperature, which is much more comfortable for all the parts in the unit and resolved the throttling issues to less than 5-10%, dependent of the unit.
Tested on:
PX5 (RK3368)
CSN2 (RK3368) ...which was delivered with a complete closed top cover. I got temperatures without any running apps of something about 85°C, because no ventilation was possible.
RL7A (RK3399)
SC9853i
Guys I’m in search for heatsink that fits my 1din PX6 unit. Do you have the measurements for the module size I need to cover with the heatsink?
Thanks

I added this to mine:

the temps on my px5 swap were 90c which is way too hot for my liking, with this it never went above 60c and you cant hear any noise.
Hi, great job. Congratulations. Anyway, where to buy Alex's android fan kit from?

Directly from him. Search for his channel on YouTube, there is somewhere his WhatsApp number written. Just contact him over there and ask for fan kit.
Don't know if this is the right location to post this but I just purchased a Vanku px6 4/64 and had every intention of at least putting a heat sink on it and I was pleasantly surprised to find this.. and it was even secured with screws. Win win View attachment 5114453

Sorry don't know why the picture isn't showing. It is a pretty robust heat sink.

My solution is a low-noise 12v fan stuck on top of the heatsink with strong double-sided mounting tape. Works like a charm.
Attached is the picture I was trying to show earlier. This is the stock heatsink in the Vanku
Edit:
Sorry, I give up. I can't get the pic to show.
I simply put an old intel mobo southbridge chip heatsink on a px6, some of them are very large
It has very long fins (over 1 1/4 ") by chance i could mod it to put longer screws to hold the px6 in place with the added heat sink
Fully passive, never had any problems
I simply run my PX6 with no lid. Makes zero difference to induce RF noise etc and my temps are cut in half for free.
Kudos to Alex (Ati_gangster)!
Simply sent the width of the original cover and the position of the two side holes and the size of the favorite fan (not included in the scope of delivery) via WhatsApp and two days later I had my cover in the mailbox. The fit is great and my fan fits perfectly into the existing holes.
