What is the maximum safe fan speed during GPU overclocking?
I own an Asus GTX 750 with 1 GB OC GPU, currently overclocking but worried about heat. I need to manually adjust the fan speed while gaming or under full load. Right now, at 100% load, the fan runs at about 2600+ rpm in "auto mode," keeping the GPU temp around 81*. I’m curious if I can boost it to 2900 or 3000 rpm by adjusting the slider in MSI Afterburner. The fan can spin up to 4100 rpm, but I’ve seen it making a lot of noise when pushed too high.
🙁
I’m looking for a stable overclock with temps under 80*. Could you recommend a suitable speed if it’s possible? Also, what would be the extra power usage with this adjustment?
Also, how much does the power consumption increase in this scenario?
Minimal impact overall, particularly if you use the fan profile only during gaming. It's more probable you'll upgrade your GPU before the fan fails. Reducing the GPU core temperatures caused by higher fan speeds offers a better chance to extend the GPU's lifespan than focusing on fan longevity.
You can operate at high levels as desired. At most, you might reduce fan activity slightly when running at high or near maximum, though it's more likely you'd upgrade your GPU sooner. Concerning power usage, the increase is limited to a few watts at most.
You can push performance as high as you want. The fan life might drop slightly at high or near maximum speeds, but it’s unlikely you’ll need to replace your GPU soon. In terms of power use, the increase is minimal—just a few watts at most. My fan ran at about 60% (around 2725 rpm) without overclocking, while my GPU stayed under 100% load and reached 80%. I’ve customized the fan curve to keep the fan at around 65% (2950 rpm) from 70% to 80%, and I’m wondering if this will affect fan longevity or have almost no impact...
