on a T95Q box, the processor heats up to 75 degrees Celsius when doing something heavy like trying games, you find that normal? I added a huge PC heat sink but I have to keep the box without the top cover.

Are you OK with the CPU heat ?

I have a pc heat sink on mine without the fan (passive cooling) because I want it to be 100% silente.
I use another such fan at my new H96 Max X2 (with similar results).

hmm..
My devices:
Allwinner a31 (dad) = Intel Northbrige cooler
Allwinner H8 oc = Thermalright true copper
Allwinner H6 = Thermalright HR-05 copper
Allwinner h64 = Stock ( remix mini )
Amlogic s805 = northbrige cooler
amazon 4k stick = connected to the large surface area of the metal bed
amd gaming pc = 2x zalman resonator v1
All are passive cooled...all of the heathsinks are from my youth overclocking days
On arm I use plastic clamps to hold the cooler in place
Note:
If i needed heatsinks.. a bunch of local kringloop stores sale them really cheap 1 or 2 bucks ( small to really large )
- left over parts from throw away pc's

On all my divices, I remove the stock small cooler from the cpu, add good computer cpu termal past and then a huge heat sink I remove from old nvidia graphics cards. I fix it with metal springs wich also act as heat sinks.
If the box has no hols I make some or remove something to let the heat get out. For example on the t95q I remove the plastic holding the leds, and use clips to fix em.
Now the cpu never go above 55 degree on heavy load, idle is around 25 (the room is around 20).
You guy use fans to cool the plastic in the bottom of the box, this is no sens.

There is NO need to "keep the box without the top cover"!! There is no need to open Holes!!! There is no need to destroy permanently the apearance of your box.
If by doing what we suggest we lower the temp by 10 to 15 degrees celcius, thats more than enough (and we have an intact box!).
At the same time we lower the temperature (10-15degrees), we recycle old PC parts and we have zero cost. Not bad I think.

I loath excessive heat on most electronics. I am for any method the user wants to employ to lower temps. I have done some myself that are stealthy(OEM look), and others that are much more obviously modded, almost Steampunk.
I am a "function over form" type. I like good looks too, but favor function, so whatever it takes to run cooler is progress in my opinion. If it can be done passively, all the better. Much of my tech is in a space that is not climate-controlled. During the Spring/Summer months, ambient temps can start as high as 100F/37.8c. Often active cooling is required to keep box temps reasonable.
I also am a promoter of holes. By holes, I mean ventilation. The overwhelming majority of boxes I have seen, or had, have had poor case ventilation. The topic has been a running theme on FT since I have been around TV boxes. Holes can be added in ways that are not visually repulsive. Of course, good airflow starts by encouraging heat to take its natural course, to rise. Holes in the bottom and holes in the top are the obvious choice, but careful consideration can often result in airflow constantly moving across the heatsink. If the case can function as an effective quasi-thermal chimney, the need for a fan will be considerably reduced in most operating environments.
As known, many of the 12v PC fans will run on 5v, with reduced, but adequate-to-cool, airflow and less noise, so I prefer the 12v fans running at 5v, specially the 80mm or 120mm sizes. They are less noisy than a similar sized 5v fan running on 5v. Someone, who shall go unnamed(they know who they are), put me on to the small USB fan speed controllers(seen below). For noise reduction on boxes with fans(and no OEM speed/temp control solution), I have considered modding one of the modules and incorporating it into a case.
As long as you're having fun and getting temps down, I say good job.

Anyway, I could have made pretty holes that would have had an oem look, I have the tools!
Passive cooling is way better than having a spining fan 24/24, even if it's quiet, I could hear it clearly at night, for example. Especially if we compare passive cooling of a CPU to active cooling of a piece of plastic at the bottom of an android box !!

It functions with 5volts (although the fan is 12V-so with less airflow but still adequate as @Risky Dude already mentioned) and there is no noise at all.
As I already stated I lower the box temperature by 10 to 15 degrees celcius. Of course if this is not enough for you, you can keep your box without the top cover (because of the heat sink) or make holes or whatever you think is better for you.

I repeat my opinion that you DO NOT have to open your box for the following reasons:
1. By using an old fan the way I and others suggest you lower the temp by 10 to 15 degrees celcius. This is more than enough.
2. You never touch or open the box so your guarantee is valid. Also you don't alter the external appearance of your box in any permanent way (e.g. by making holes).
3. You recycle as you can use old PC fans and other such old parts.At the same time you have zero cost.
4. The fan functions only when the box is turned on (if you connect it to the USB port).
5. If you use the old PC fan which is 12Volt because the fan gets 5Volt from the USB port it is extremely silent. It still gives enough air flow to lower the temp by at least 10-15 degrees.
6. At the end it is a way that you can first try, without altering anything to your box. If it is not enough for you then you can do anything else you think is suitable.

Why ? because heat is the enemy of electronic components, and any means is good for eliminating it.
On the T59Q, which I use daily, I had a temperature of 70 degrees celcuce with the original firmware, it was a silent killer that would sooner or later kill the box. (this is no longer the case with a custom firmware)
If I didn't have a heat sink that fit, I would have either left the box open or drill holes, but I would not have put a fan from outside. like you're hot in a jacket, you put yourself in front of the air conditioning but you keep the jacket, it doesn't make sense, you have to remove the jacket first !
it is ultimately a matter of personal preference

this is my T95Q, you can see the ventilation space and the black heat sink inside.
Remember, if you want to do like this use a good computer termal past between the heat sink and the CPU, I lowered another 8 degree switching between the stock termal past and the computer termal past.You may only view thumbnails in this gallery. This gallery has 1 photos.1 Photo
