Zero Fan Spin Below 50C - Do You?

[mealto]

Noticed the Asus Expedition RX 570 8GB defaults to no fan spin when GPU temp is below 50C. Basically, it idles at at 50C +/-. You can disable feature and the fan default sot 35% fan speed or so. This keeps idle temps at around 40-44C. My last card idled at 35C and those days are over.

 

Do you keep your fan at 0 until 50C or do you run your fan on all the time?

if I were on air cooling, I always kept my fans on with on my 1070 before I went water cooling and same with my 2080ti before I put a water block. I am not a fan of the zero RPM mode personally so I just enable a fan curve to have the fans always on.

I feel the same way. Wattman does not allow me to go below 30 or 35% of fan speed no matter the temperature. Pisses me off actually.

thats not wattman, its usually a minimum in the BIOS.

I tend to. I have a 1060 6GB. Even with the fan speed set to this, I never reach above 70C when gaming

With my MSI 2070 armour, fans don’t start spinning till 60c. Never touched the fan curve, and even if they spin, I can’t hear them. 

 

Left it all on auto and seen max temps of 71c after heavy benchmarks. In game highest goes around 69c ish

0db/ not spining at low temps are great.

the most fragile /easy to break is the fans on gpu, also accumulates dust.

it preserves fans much better for longer lifespan.

also consider what how often the gpu is at load compared to idle.

nothing can break under 60C

 

this was the main reason I chose msi gaming gtx970 over gigabyte g1

It's under 50c now? My 980 Ti only start spinning over 60c, card usually idle on high 30 or low 40 with no fan spin. Great feature imo.

29-34c when idle/normal web browsing/word etc for me

I am not worried about the GPU idling at 50C. It's more of the annoying heat the PC pushes out. Here is the real issue. When it idles at 50C, temps below the desk gets noticeably warmer! lol So:

 

1. If it idles at 50C and the PC exhaust fan will remove heat inside case. Rest of components are not hot.

2. This is an odd one and I may need someone with more understanding of thermodynamics. With a custom fan curve, the GPU fan is keeping the GPU cooler but is it because it has already removed that heat from the GPU and into the case already? If so, even idling at 40C, would this scenario still exhaust the same amount of heat our of the PC?

 

Also, at stock setting, gaming gets up to 77C. With a custom fan curve, it games at 71C which I like a lot better.

 

And it doesn't seem like a BIOS lock. MSI Afterburner can run a fan curve to make the fan spin below 30%, just Wattman cannot do this.

I see other RX 570 owners say the same thing. Do you guys have the Zero Fan option disabled so the fan spins 100% of the time?

I have a RTX 2070 armour. I never touched the fan curve on my card and the fans don’t spin up until 61c or so 

[dgsddfgdfhgs]

the feature is actually start to spin on or above 60C and stop at 55C
