Active cooling with standard cover

Hi guys,
here my solution of active cooling
Components
- battery: CM5095-WE (MicroUSB in/out) or any other 5V battery
- Fan: Delta EFB0612MA (60x60x10mm, nominal 12V (running at 5V), soldered to microUSB female connector)
- Fixing: velcro strip
Result
- no noise
- no vibration
- low weight
- no need to remove back cover of the Note 4 (tested with Mugen 6640mAh extended battery)
=> no overheating :good:
Good luck

works perfect
excellent job done, Bro
...rebuild your solution -to be honest it doesn't look as good as yours, but it does an excellent job.
Tested about one and a half hours nonstop gaming without any warnings or overheating issues.
Being driven at 5V, the 12V FAN is rotating in super-silent mode, to be heard only in absolutely silent environmental conditions.
No need of removing back cover off the phone. Due to the constant airflow, the Note4's overall surface temperature is less then handwarm.
I didn't expect that much high efficiency for this simple crafting.
Just wondering why Samsung didn't implement it on GearVR from the beginning
ThX to reikow and keep up the good work
sincerely

Is this exhausting the air out or blowing it into the device?

it is blowing the air to the device.

Thanks for this post. Modded my unit also. Makes a big difference.

Definitely works miracles! Now the Gear VR can run until the battery dies without having to cool down after 15 minutes or so of running.

I'm sorry drilled, my standard cover. Instead, 3D print of the cover.

Looks way nicer than mine, but it works..... GPU centrifugal fan with 2s 850mah lipo battery...
Can be run off battery or any usb charger. Moves air throughout the whole unit and also prevents fogging issue. No vibration, hardly any weight, and keeps a nice breeze on your face

How is the fan cable connected? Does a micro usb have 3 wires like the fan does?

Can anyone tell me how the micros usb cable attaches to the fan wires? What wires did you solder, as the fans usually have 3 wires. Does the micro usb also have 3 and what ones match up?

Thank you so much for this great idea. I completed mine a while ago and was playing for over 45 minutes and the phone did not even get warm to the touch. I used a longer USB cable so that the battery does not have to be on the visor itself but can sit in the chair or couch next to me

usually the fan has a plus/minus and a separate one to return back the speed of the fan. Just try them to make sure spins in right direction - look up which pins on the usb you need! You can't really hurt the fan if you try wrong - so just try them!

Thank you. I got the mod done already and all working Great. Played Herobound online for over an hour and no overheating at all. Used a long usb cord, so I can put battery on my side and not weigh down the headset. Also used hot glue gun on fan, over hole in visor plate, and worked out very nice.

Solutions I've seen here on XDA or on Youtube seem to be bulky, require soldering and often modifying the protective case in some way.
I open this to debate, as the cleanest Gear VR cooling mod seen so far. WITH DOUBLE FANS.
Look it up and feedback is welcome!

I like it, but won't it still heat up more than the cover modified type of mod, due to not pulling in the room temp air from outside of the case cover?

There are six wide enough air intakes/exits (roughly 50mm high and 300mm wide).
Two on the sides and four spread upwards and downwards within the design of the protective cover itself.
I only gave it a first run with a movie and a heavy 3d game yesterday for about two hours so of course it went smoothly. No fogging (fogging was present even in the movies before) and no heating warnings during the game.
I'll let you know after more usage and hopefully if I have time with longer usage sessions.
It does though make a tiny winy bit of hiss due to the two fans blowing close to each other. But that doesn't bother me as I often have earphones or headphones on (you only notice the air hiss sounds when you take the earphones off).
This video shows how big are the in-design air intakes/exists that we all have with our protective cover.

[Review] ZeroLemon 3500mah Battery Case

I've been using this ZeroLemon battery case on and off for my Galaxy S6 Edge in the past couple of months since May and I have to say that I like it a lot!! I've been a fan of ZeroLemon since 2013 when I began using their products for my Galaxy S4 (3000mah & 7500mah batteries) and this product has lived up to my expectations.
This product consists of 3 main parts - the 3500mah extra battery, a little bridge connector that connects the 3500mah battery to the micro USB port on the bottom of the phone, and a TPU case. Here is a picture of what they look like:
It is very simple and easy to put together the package. You first connect one side of the little bridge connector to your phone and connect the other side of the bridge connector to the battery. You then insert the phone and the battery together into the TPU case.
Once everything has been put together, it looks like this:
Putting on the battery case makes the package as tall as a Galaxy Note 4 and about double the Note 4's thickness.
I expected the phone to become super heavy but I was pleasantly surprised that it wasn't too bad. My old Galaxy S4 with its 7500mah extended battery was heavy. This 3500mah ZL battery case is not bad at all. Despite the tallness and thickness, I am still able to use the phone easily with one hand, which is very important for me. The phone is still comfortable to hold and use.
One thing that struck me was the improvement in the quality of the TPU case ZeroLemon used for this product compared to its older TPU products. The feel is way better as the TPU material is now more solid-feeling with a nice texture to it. The older ZL TPU case material felt spongy and cheap in comparison. Kudos to ZL for improving their TPU case material and quality.
Fitment of the TPU case is very good as well. There are no glaring gaps anywhere and the phone is secured snugly with no nervous looseness or movements.
The main star of this kit, of course, is that extra 3500mah battery and it performs very well. My wife and I went far away from home yesterday to do some outlet shopping and I knew I would probably run out of juice during the trip with all the GPS & data usage. About the middle of the day, my phone battery was down to about 30%. So I activated the ZL 3500mah battery by holding down the Power Button on the back of the case and the phone began charging itself right away. About 1 & 15 mins later, the phone was fully charged back to 100%. Nice~! To turn off the charging function, I pressed down on the Power Button again. Very simple.
There are 4 indicators on the back of the case that lets you know how much charge you have left in the 3500mah battery. After that charging session from 30% to 100%, I had 2 bars left which was what I had expected.
So how do you charge the ZL battery pack? You connect your phone charger cable to the microUSB charging receptacle on the lower-left side of the battery case. I noticed that the ZL 3500mah battery gets charged first, followed by the internal OEM battery. After plugging the charger in at night and looking at the phone in the morning, both the ZL battery & OEM battery were fully charged to 100%.
To sum things up, I'm very happy with this ZeroLemon battery case. It is easy to set up, easy to hold and use, and the important battery extension capability just works as advertised.
++ Pros ++
-3500mah backup battery capacity!!
-Easy setup and comfortable to use.
-Good quality TPU case.
-Battery charges fast for not being a FastCharge type.
-The raised lip of the TPU case allows the phone to be placed face-down.
-The case routes the sound to the front so the phone with the case on becomes front-facing rather than down-facing.
++ Cons ++
-A bit difficult to slide the phone inside the case if you have a screen protector on the phone and don't want it to get wrinkled up. It's possible to not mess up the screen protector but takes some effort.
-At maximum volume level, the audio sounds a bit hollowed out and distorted. If one lowers the volume a couple notches, distortion goes away but still not as clear-sounding as having no case on.
I would definitely recommend this battery case to any S6 Edge user who doesn't mind the extra bulk of the case, doesn't want to carry around a power bank, and want some peace of mind knowing that their Edge will easily last the whole day and more. :good: ​

I've heard about Zerolemon that their batteries are powerful. Maybe I'll give it a shot.

Cheap stand available on Amazon. Just $6

I needed a new charging method after metal band replacement.
Here is the band:
http://amzn.to/1P1YK8s
And this is the stand:
http://amzn.to/1P1Z5YA
(Mine is black, but there's no pics)
I simply bent up a beer bottle cap, wedged it into the hole, and added a dab of hot glue. Pressed the charging disk and the cap together (I like this better than the plastic cap as the magnetic pull from the disk works on the bottom too), and you're done.
Total cost, minus my steel band, $5.99. I'm very happy with it and putting it on and off the charger is very easy.

Love the idea, original charger is just too light, whenever taking watch off it wants to come with it.

I just use Blutac to hold charger to the stand - works for me.

not your idea though, is it. The guy who did the original Spigen stand of what this is a clone of was first.

has anyone used this one?

Cleanest mod USB Fan + Powerbank for Gear VR

Pictures of mod items down below.
Back to the topic of modding the IE Gear VR for the note 4:
I just received my IE unit days ago and had a look at the various modding attempts be it on this thread, youtube or google altogether.
Some do look clean enough still I was pondering the idea of the cleanest sleekiest modding design, while keeping costs to a minimum.
After about 3 days of hectic googling, I came up with the following:
1- 8000mah Note 4 extended battery:
Link: http://www.ebay.de/itm/391342722159?_trksid=p2057872.m2749.l2649&var=660582850100&ssPageName=STRK%3AMEBIDX%3AIT
As opposed to the many more or less higher capacities at about 9000mah up to 10000mah which cover more width area of the phone. This piece at 8000mah has the same proportions as the original battery, only two times thicker.
That should be taken into consideration as the heating parts on the phone when used with the VR are usually around the back camera upper area. Having a normal sized extended battery should leave free room for air-cooling later on. As opposed to the wider kind at say 10000mah (Wink Wink Zerolemon ) that unfortunately cover the heating-up back side of the phone, theoretically causing the air-cooling mod not to work.
Last but not least, this battery at its offered capacity roughly costs 10 bucks. It should be a steal, once I'll confirm it is indeed offering a close enough performance to its claimed 8000mah capacity. More on that soon.
2- USB Cooling Fan
Link: http://www.aliexpress.com/item/1Pcs-Cool-Cooler-Cooling-Fan-USB-Foldable-Folding-Pad-w-2-Fans-for-Laptop-Notebook-Free/32435788330.html
Now to the main course, the cooling!
Most mods I've seen use an elaborate approach based on adapters and long cables.
Now I have found this piece, two fans already USB'ed and sized at :
167*66*20mm (respectively: Length*Width*Thickness)
These proportions should easily fit my rough calculation of the VR removable Front cover which more or less are:
180*80*18mm
USB is a 5V DC easily powered by any powerbank.
Price is just about 3 bucks. well 2,36 euros for me.
More on that after I receive my order and see to it.
Plan is double sided tape. More on that later.
3- Powerbank for the USB Fan:
With portability always in mind and me not willing to give up any aspect of that portability. Mods I've seen around just velcro-strap a sizeable powerbank on the headstrap or backstrap then call it a day. That is neither cool nor comfy. It is of course a matter of opinion and that was mine. Anyhow, here is the link of the smallest powerbank I've seen.
Link: http://www.aliexpress.com/item/keychain-Mini-Powerbank-1800mah-5V-1A-Mobile-Phone-Power-Bank-Mini-usb-Universal-Portable-External-Battery/32585393797.html
proportions: 51.5*41.5*17.5mm
weight: merely 70g
These proportions perfectly fit the left side of the VR where the GEAR VR OCULUS logo is.
It is planned to be installed by surrounding the edges and corners of that logo with thin double-sided tape/Velcro. That should keep the logo visible, harm the appearance as little as possible and hold the 70gram powerbank just fine.
Also more on that when I receive the goods.
The powerbank has a decent 1800mah for something the size of a key (designed as a keychain). That should be enough to run the fans for two days at least, again theoretically.
The price is an alluring 10 bucks or less if site's discount is applied.
Edit: If all works according to calculations, this mini powerbank would be sprayed white so it would fit with the IE Gear VR colors, and not stand out with its gold finish.
Conclusion:
My note 4 with the original 3220mah holds about 3h to 3h30 inside the VR without mods.
With the 8000mah it should hold up double the time or if conservative then a decent 5 hours. Again without cooling.
Double Fan cooling should be extreme as most of the seen mods report no heating whatsoever with just one fan, still lets see if double fans might be the new standard !
The Powerbank is to be installed as plug and play (with velcro) on the side. Just press it in or pull out from the left side. Easy.
The powerbank's own proportions are fitting the left side, so neither appearance nor design are compromised.
At 23 bucks, this is the lowest cost/design mod seen yet.
Well not seen it perse, I have to make it :laugh:

Actual DIY mod
Update 07-05-2016
I recently received my orders for the DIY and started working on it.
Challenges were met, but let's keep it brief.
My piece of advice on all this would be:
No matter how good your calculations are (for this particular kind of mod that doesn't involve damaging or altering the cover case but rather duct-taping your way around it):
Always make sure to double check your calculations as you will be working on a Millimeter -mm- basis here. . It literally took me tens of trial and error and loads of patience to find that particular right spot where the two fans don't hit on anything be it the camera or any part of the phone .The concave form factor of the protective cover definitely was of no help as only the center can be used, and that center hardly houses two fans.
So the fans had to be stripped down to the very bone, taking off every single part that had the potential of being removable. (used a heated knife and/or scissors)
The result can be seen in the video, where literally less than 5 millimeters separate the fan blades from the highest point of the phone, being the camera.
I did mention "this particular kind of mod" as not only does it not involve any cutting into the cover nor holes, but also it is built with completely removable material eg: Double-sided duct-tape and double-sided Velcro.
That provides two advantages: a clean design obviously as the title suggests and the possibility to keep your case undamaged and unaltered by simply scratching off all the Velcro and duct-tape at some point in the future, if you decide to.
I haven't received the 8000mah extra battery (mentioned above) yet so I'll update on that at a later date. Although now I highly doubt it would fit with the two fans, if one keeps the protective cover unaltered.
One last piece of advice: a 4mm wide double-sided duct-tape on the back of the battery is a good trick to keep it well snugged in the phone, not suddenly falling down, and still keeps the battery easily removable later on with finger pressure.
Pictures down below, and a short video made just after I finished the project (ps: humming is from something playing on the laptop, the two spinning fans don't make any noise).
Link https://www.youtube.com/watch?v=kXPEArWpgm0&feature=youtu.be
Shoot away your questions, I'll be happy to help!
This is my first attempt at any sort of DIY, and I'm glad it turned out just fine, and also happy I can give something back to this great community!
So much for trying to be brief ! Sorry !
Cheers.

ZeroLemon Note 8 10,000mah battery case combo

First off, let me say this is a great setup for a power user and is the third ZeroLemon 10000mah battery case I have used on a mobile device. I use my phone for everyday business and multimedia use around 12-13 hours a day. I am constantly in the car or traveling for clients and have very little time to actively charge my phone on the move. This battery case combo was a no brainer for me.
So far I have been through 5 complete charge/drain cycles. Charging this battery case usually takes 8-10+ hours and holds a charge pretty well from what I have tested throughout the week.
The overall size and feel is great, although it does take a beautiful thin phone and make it into a hefty brick. I would say it is relatively the same size as 3 Note 8 phones stacked on top of each other. For me, this feels great and gives me a bit more piece of mind when handling the phone all day. However, your basic consumer may not like trade-off. That though, is a positive trade-off for me to have stellar battery and usability to get me through the day, worry free.
The case fits the phone very well and I do not worry about it coming loose, shifting etc...If I were to drop it I don't know how well it would absorb the impact, or whether the phone would stay in the case itsself. I'm not going to test that though. The s-pen can be a bit difficult to get out/in. This isn't an issue for me as I rarely use this feature. All the buttons line up with the respective case buttons and pluggin in the charger has ample clearances etc. The camera and fingerprint sensor are easily reachable as well.
Overall, this was a great purchase and one I will make again for future devices. It does exactly what I need it to do every day, and it does it very well.

I don't think anyone could have designed an uglier solution

Way too much bulk to add considering how long the battery last and how fast the Note 8 charges. I have an external battery, but have only used it once

I bought the 10000 mah lemon battery as well via pre-order being I was coming off a rooted Note 3. Once I seen they was making a 10000 mah lemon I went and bought the Note 8 immediately. Not only have I've gotten 3-4 days with moderate use but it can also be used as an EXTERNAL battery for anyone worried about the added bulk or having to take a more protective designed case off to use the lemon case and battery.
I haven't even seen this option advertised in the Amazon reviews, Zero Lemon website or anywhere so decided to share. Basically just buy any USB C to USB C cable like this but shorter if you want "AmazonBasics USB Type-C to USB Type-C 2.0 Cable - 6 Feet (1.8 M... https://www.amazon.com/dp/B01GGKZ1VA/ref=cm_sw_r_sms_awdo_t1_icXvAb4CR5EGC and plug it in the actual white and black battery that fits in the lemon case. There's a input and output insert. Use the Input slot and plug the other end into the Note 8.
This works just like an external battery where you get the option to have it in the case or out the case. Also to add. When flat on a table, the lip for the case slightly raises the phone off flat surface which helps with the glass not touching. Although it's not designed to protect the phone I dropped mines twice off a dresser and not a scratch. Landed on its back possibly because of the weight. Hope this helps anyone in deciding.
