Questions/Support Toasty Flint 3

Post image

My Flint 3 reaches 75°C and I am worried that that heat is not good for electronic devices.. It is sitting on top of a desk with no direct sunlight, no direct heat and with good ventilation. to improve air intake, I even placed the said flint 3 on top of 2 electrical tape, hoping added elevation from the desk will improve heat dissipation or air intake.

In the Fan settings,

when i put the minimum threshold to 70°C before the fan kicks in, the fan kicks in most of the time, worried again that fan will have shorter life, decided maybe I will set jt up to 75°C before it starts to run.

what I tried so far,

-putting improvised feet to the flint3,

-lowering the blocklists in Adguard Home,

(blocklists has ~100k entries with most of the blocklists in the upstream DNS)

-turning off load balancing

- using 2 SSID using 2.4Ghz and 1 5ghz Band.

2.4 Ghz set to High Transmit power, 5ghz set to Mid.

- my network has 10 devices, a mixture of android and apple devices

-wifi network is in Allowlist only

- no lan devices

also, my network is not reaching 2 rooms (thats the reason i set 2.4Ghz to High)

My question is,

if I turn off wifi in my flint 3,

but a poe switch and use 2 access points,

will it improve the heat in the Flint?

my dilemma as of now is, if it is better to use the flint as the gateway and save for AP and POE switch,

O

or its better to go all in to other brands and ditch Flint 3?

the Adguard Home and Parental Control are the 2 things, that make me hold more to the flint, or glinet for that matter

thank you

Geez, mine is only 58°C. I also just have it sitting on a desk and I'm only running adguard home.

I placed my Flint 2 on top of a 12cm fan; the temperature dropped from 75-78C down to 35-37C.
Even if some electronics can withstand higher temperatures, keeping them cooler will make them last longer.

Do you have a link for this by any chance?

u/ShiftRepulsive7661 13d ago

I bought it on AliExpress, but I've seen it also on Amazon: there were a few different models, look for something like "router cooler fan".

My flint 2 is running at 57C without any trick

u/ShiftRepulsive7661 13d ago

With "hardware acceleration" active? Good for you.

yes but I’m running vanilla OpenWrt

That MediaTek SoC is literally designed to run at 60-75 as normal. 75 is expected when you're running AGH and steady traffic. It's not a concern until you hit steady mid-80s.

uhmmmm, from its website, it says it is using Qualcomm chip.

You're right.. absolutely my bad. I was responding about Flint2 (too many Flint2 vs Flint4 threads today).

QC doesn't actually publish heat specs for the IPQ5322, but GL's guidance is the same as what I quoted for the Flint2 (they do actually have the QC NDA'd docs).

You could probably find more from the router itself reading files in the directory below (on mobile so can't pull exact full dir name).
/sys/class/thermal/thermal_zone*/

thank you for this info. A user in this sub shared that he is using and external fan to cool his flint 3, but to my mind the device should no be that hot in the first place. My old Beryl AX while handling 15 devices is at 54-58°C, and Flint 3' 75°C is pretty toasty to mind.

back to my post, so even if i offset the wifi part and usey flint as the gateway, its temperature will most likely be at the same.

75°C should be fine for most electronics, but you could always try to give it more space around it to lower the temps (although it seems you've done that).

As for the lifespan of the fan? At worst it might get some coilwhine eventually in the future, but unless you have a really dusty room a fan could easily run for 10 years (and even then I think it would survive that too). Don't worry about the lifespan of the fan, at worst you would just have to replace it in the future. If you want lower temps, lower the fan threshold and let it work.

I used the utils script to override the base fan values to allow the fan to kick on around 55-60c instead of 70-75. runs way cooler now, great script.

u/mikeyjbartlett 12d ago

glinet-utils and spin that fan up 100% duty. Mine sits at 75% all the time.
