A fan is $10-$15 to replace. Let that GPU burn up and see how much it costs to replace then! No reason a GPU should be ran at 76C or above unless you live in the Jungles of Vietnam.

Mining is illegal in vietnam xD
And i really love vietnamiees food <3 ;3

Nothing is illegal until you get caught, and who on earth is going to find you in the jungle?

So where do you guys buy replacement fans? It seems to be quite hard to find an exact match for the existing GPU fan.

I've found mine for sale on eBay, they are nothing special, just make sure the fitting and diameter is the same with yours and you should be fine. They won't make much or any difference with your genuine fans, don't spend a fortune on something consumable.

I've already contacted MSI (The gpus i got from) and they will send me Shudle with how much for each Fan + i will replace Thermo paste to stay them cooler for longer(Also msi will do that)
Only reason that MSI will do that they campany politic in my country is they only can replace Thermo paste for GPU or i void warrianty for example in UK u can change thermopaste without their premission and still having a warrianty(only if you phissicaly do something to card you void it) :/

Merit me or don't.

Mine are set at 37% and the temperatures are 51'C.

Auto is undesirable, initially video cards are not provided for mining, so only the manual mode, depends on how the farm is built, quite acceptable are 60-90%.

I'm using a fixed fan speed and set the fan of my AMD-cards to stay below 60°C.
Rx480 ------- fan 58% - 64%
Rx580 ------- fan 53% - 58%

P. S. The fan speeds I posted are shown in claymore, Sapphire Trixx values are lower.

There is no correct or right way to set the fan speed.
I have many cards from 2014 that are still running with an average temperature of 85 degrees. And they never had a problem.

Byt if you wanna be more careful you can trust Nvidia and use the temperature they advise, so 75 degrees.
I personally set the minimum fan speed to 50% because I want to avoid driver related problems

The simplest thing to say is that it depends on your preference. I'd recommend having the fan at 100% by 80C might be a good balance for noise reduction Personally, I have my XFX BE 7970 set to hit 100% fan usage at 60C, ramping up linearly from 30% fan at <= 40C.

I have always thought that is is best not to run them at full wack 24/7. I will usually see what the temperature of the cards are and adjust if they are too hot.

On the other hand it is cheaper to replace a fan than to replace a gpu.

Hello guys i wonder what fan speed is best for our GPU on mining?
100% or Auto ?

My opinion, do auto fan if high temperature we add another fan so that the VGA card fan is not easily damaged.
In southeast asia there are only two seasons of a dry season and rainy season, sometimes in very hot weather, I set 100%, depending on the weather situation.

100% will kill your fans.

Not sure about ATI cards, but Nvidia cards allow you to set a temperature threshold that lets the fans operate at whatever speed is required while limiting the amount of power the cards draw. Not quite auto, it's a bit more complex, but super effective.

Fans are consumables. Replacement fans time by time is much easier the replacement whole GPU. So 100% fan speed is not so scary. But using MSI AB for example one can setup fan speed curve from 40% fan speed at 50C to 100% at 70C temp

I think the best idea is to set fix speed of the fans - about 60-65%
by this speed I'm aiming to prolong the lifespan of fan's motor and it is enough to keep the card temperature around 65-70 degrees and noise level is also acceptable . so it is win to win

80 to 85 % or less should do ... that way you save the fans or they last longer and not a lot of noise, they stay cool enough.

mine are set at 75 to 85 % usually stay below 62 C all year long , i have 14 cards and always adding more, one or two cards every two month or so .

It depends on what situations you are faced, the main function of GPU fan is to keep your card cool. As long as auto setting giving your cards temps below 75, keep going with it. Except your cards temps going hotter with auto setting, you could maximize your cards fan speed. But remember 100% fan speed setting would make your cards fan more quickly damaged but a fan can be replaced with a new fan right?

Heres some free but good advice.... If you have windows in your mining room, cover the windows so the sun cannot shine into the room. The sun adds radiant heat and can heat a room up very fast! Use curtains, blinds or even tint, cardboard or paint the glass on the windows.

Use Auto with MSI afterburner. You can adjust the Fan curve to your liking. I like to Keep my gpus below 65c nice and cool. However most people keep it below 70c. Generally, I set it starting out 60 percent fan speed if gpu reaches 60c. If temps go to 75 degrees it will automatically set it to full 100 percent fan speed. So i have a straight line from 60 percent fan speed at 60c to 100 percent fan speed at 75c.

My gpus always stays between 62-65 degrees and fan speed always tends to range from 60-70 percent depending on time of day. I do have good proper exhaust fan ventilation.

I do not like fixed manual fan settings because if there was ever a hot day, or your box fans circuit breaker trips, your gpus will start roasting up and climb up in temps b/c you had no auto setting to ramp up the fan speed if temps go too high. Plus always running out fan speed at 100 percent will wear out the fans so having auto settings will slow the fans down if the gpu temps is low

Typically I set the auto speed vs temp. The ambient temperature in my mining room stays around 39C, and GPU's temp is quite stable at 47C. For manual setting, I always set it at 75%.
