Did i just decrease the fan life on my 1070?

[Vengeance_K1ng]

SO today i bought a MSI 1070 Gaming x edition, and i set a fan curve and i realized when i got back after a few hours of updates and idling, my gpu fans were constantly turning on and off, did i damage them in any way?

Its not an issue , its a feature!

Seriously, look up 0db fan mode

I know, but wont the constant on and off hurt the fan? seriously it was turning on and off every 2 seconds,

[ScratchCat]

No, some fans actually use this on and off to control speed called pulse width modification PWM.

I think this on and off every 2 seconds or so has been found in a few partner 10 series cards and is nothing to worry about.

Ill just see if i can confirm this.

Even though the question has been answered already I'll confirm that this won't damage the fans. Fans don't generally die unless you hit them hard enough to break the plastic.

Should prolly stick something in there to keep them from spinning or unplug them. They should last longer that way.

noooooooooo what are you thinking your motor will burn out completely its a feature and its meant to do that you never want to do that.

Motor won't burn out. If they did, that would also solve the problem.

PWM is a method of modulating power digitally and is used where having variable characteristics (motor speed, light intensity, etc) is required.  For example, if you want to run a 12V motor off a 12V battery at 50% speed, you would switch the 12V source off and on (for an equal amount of time).  The higher the frequency of this switching, the smoother the operation is.  In practice, this means the frequency to which this works is tens to hundreds of times a second, not once every 2 seconds. 

 

The most likely reason this is happening is because he's putting just enough load into the card that it passes the threshold temperature for fan stop, cools itself back bellow said threshold and repeats this cycle.

 

OP - The fans will be fine.  My concern is that the card would be reaching the fan stop temperature threshold at idle.  I would return the card to the factory fan curve and let the computer idle for a bit.  If it's still doing this, take note of the GPU temp and post it here.

If the fan motors burnt out, the card would die under load, stopping a fan from running by sticking something in it is never a good idea.

 

OP, it's fine 0db fan mode.

I like to run my fans at idle though, i am not happy with this 0 fan mode. i keep it at 20% and no more problems, is that ok to keep it at 20% at idle?

It would be a good death.

I don't agree with you here. PWM doesn't function that way. It sends pulses of 12V current to the fans, instead of supplying a constant stream of current to the fans. It uses pulses to control the fans as it allows the control to be more granular, but the fans should not be shutting on and off like that.

 

That being said, I might be wrong.

20% at idle is completely fine.  Just to be clear, it ramps up past 20% under load correct?

Except mine where the fan blade axle thing separated and threw it off balance

Came off my Trixx 290.. The clicking it made made me watercool it c: Now it can actually live through 1.46V
