Safe GPU RPM Speed?

[jiyeon]

Hi, so recently, I've gotten into the idea of running a custom fan curve for my GPU so I have less heat being generated by my graphics card and also whilst I'm folding.

 

This is currently what my fan curve looks like:

These are the statistics I'm getting from MSI Afterburner, this is full load on my GPU, which is folding at max fold power.

Now, I have my RPM quite high at moderately-high temperatures. What is the safe RPM area that I should be aiming for? I enjoy these mid-60's temperatures and it even gets to low-60's usually but today's quite a hot day and so it's picked up by a few degrees tonight.

Without a custom fan curve, my GPU tends to max out at 1900RPM and my GPU thus reaches temperatures of around 70°C.

The fan on my GTX 970 runs at 2800 RPM when I'm running F@H.

 

Honestly, people mined with GPUs at max RPM for months, so running F@H at less than 2000 RPM should be fine.

it's an electric fan

100% speed is safe , it's not a car engine , it's made to run at 100% speed much like a lightbulb can run at 100% brightness

What about from an electricity standpoint? Will I incur any additional utility bill increases from a higher fan RPM? Say for example, my default 1900RPM versus my 2600RPM.

Before i went to my custom loop i tended to run a smooth curve up to a set noise level and temperature balance. So say for example 60% fan was as loud as i liked it, and under normal conditions at load that would result in 70c, that would be fine.

Then i would flat out the curve from that point (70c to 85c no fan speed change, stays at 60% max) untill the temp hit like 85c and it would then quickly ramp up to max fan speed (85c = 75% fan speed 87c = 100% fan speed).

Dont worry about power usuage for fans, they use very little even at max speed, and are design to run at those speeds without any issue.

no , a regular lightbulb even an led one left on will effect your bill more than the gpu's fan speed inside your machine

the only thing fan speed affects is noise. no power bill (mabye 1 cent in a couple years).

i'm comfortable with 70c+ gpu temps during games.
