Toasty Flint 3

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
