Less temp are healthy for GPUs both in life span and hashing power, it's better to always use extra fan for cooling unless the GPUs aren't heating up much, anything over 60°C is hot for me, GPUs will happily work for you if they are less heaty, most of my Nvidia cards are running on 54-56°C and those with bad cooling stay focus on 60°C like gigabyte GPUs for example, just add extra cooling fans
There are two things that lower the temp of GPUs
1. The cooling system or well ventilated area where new cool breeze always comes around, this is why I love my garage, it's like natural A/C down there
2. Lowering power consumption as much as possible, GPUs tend to go higher in temp if they drawing high watts, for example my gtx1660 used to draw 70watt and temp goes up to 63°C but after Trex absolute core clock my 1660 now draws 50watt and temp goes down to 54°C
That's a big improvement

The temperature that components run is important and its true that the longer you run something at a higher temp you reduce its lifespan. This is particuaruly true with most capacitors, their life is shortened because on the temperature that they are operated at. However keep in mind that this is in the span of "years" and not "months". Most likely the GPU will be obsolete by the time that the capacitors start to go bad.
A bigger issue in my opinion when it comes to longevity of components are heat cycles. If you leave it running 24/7, I think you will have a longer life span from some gamer who plays a few times a day everyday. Basically the GPUs heat up and down multiple times and that is what shortens its lifespan. If you leave it running at a higher temp constantely then its better than heat cycling it on and off all the time.

living with a static ambient temperature of 17c is perfect for servers
Static humidity too. I recall a customer in Miami who decided to use natural wideband climate control, meaning
turning off the AC at night and opening all the windows. That experiment didn't last long.
Yes, you're right, the main factor is the lifespan, less heat, more lifespan of components
Yes every component has a thermal tolerance, if the threshold is past the lifespan shortens and there are levels for that, for example, if tolerance is up to 90c then if you keep lower that then lifespan will be more than what the manufacture said it would be, if is more than 90c, it shortens, keep in mind that while in summer and 24/7 components damage a lot but most dont break because needs a friction for that and the friction is a changing rapid environment, meaning if you live in a place where is very hot during the day and very cold during the night then that is where it really damages the hardware, meaning, living with a static ambient temperature of 17c is perfect for servers --> controlled air conditioner can do that but that is very expensive.
So it's true that temp isn't GPU mining friendly now I believe this is true, I have RTX3060ti that mine away at 61MH with 125watt and when browsing online I saw few people using same card with just 115watt, I really care about saving energy as possible so I decided to play with the GPU, mind you temp was 60°C but after reducing power down to 120 I lost 1.5MH, I was confused but the 5watt safe is not really much and I added a small table fan this make the temp dropped to 56°C and hashrate up to 61.5MH, it seems the more cooler a card works the better? By the way it's a gigabyte 3060ti non LHR, should I just buy a permanent fan for my rig instead? Or not worth it
I have a card like that one but is MSI and not Gigabyte,it is Ventus with 2 fans and not 3 fans.It runs really stable at 59.8 Mhsh and 120 watt power,also measured at the wall it is 120 watt with a Wattmeter.The settings of the card should be fairly easy:
Core Clock -200
Memory Clock maximum of +1200 but I keep at 1001 to achieve this result of 59.8 Mhsh I can go to 61.4 Mhsh at +1200 but it is not always stable
Fan speed I always keep at 83% but the cooling of MSI cards sucks big time
Yes the more cooler an electronic component works the higher its lifespan.
it seems the more cooler a card works the better?
Yes, you're right, the main factor is the lifespan, less heat, more lifespan of components
I remember some cards, polaris for example (RX 470, 480, 570, 580 and 590) works better if you did some undervolt, even in games, you can achieve more clock, with less voltage
Some chips works better with more voltage, but each chip/gpu is different
Are you running this card on a PC or rig?

I don't understand why you have such results.If the video card is located in a farm in an open case, then you need to increase the distance between the video cards to 15 centimeters and install additional 12x12 fans to supply cold air. If the video card is in the computer, then you need to add fans to the case.

well how much power does the fan use?
1.5 mh is about 12 cents a day.
lets say a kwatt costs 12 cents
so a 41 watt fan is 1 kwatt a day. Or break even.
But .5 amp 12 volt fan is 6 watts or 144 watts or about 2 cents a win.
spending 2 cents to make 12 cents makes sense.
the fan below is 3.5 watts

now if you buy it and it costs a penny a day to make 12 cents you clear 11 cents.
in 150 days you paid off both fans. it is a two fan pack.
note the fan company is not known to me. I picked it because the seller answered that it uses 3.5 watts.
