But, it may not be stable at all times, and your GPU may throttle down because of the increased temperatures if you don't have a good GPU cooling system in place. Yes, GPU overclocking can give you a 10-15 percent gaming performance boost. Always research your specific GPU specs and limits before overclocking. Please note that this is general advice and MakeUseOf is not responsible for any hardware damage that comes from overclocking. Most modern GPUs will cut out before anything truly awful happens.

This is usually a sign that you went overboard in overclocking your GPU, so pulling back the clock speed a notch should fix this up. But, if that sounds worrisome, the worst that will happen is a crash, freeze, or a blue or black screen, easily fixable with a simple computer restart. GPU overclocking can increase your operating temperatures, putting more stress on your GPU. Again, God knows why).Īlso, another bit of weirdness, when I disable the fan curve, or close Afterburner, the fan speed drops immediately in CPUID to 0.Here are some frequently asked questions about GPU overclocking and their answers. It only shows two fans but I gather this is normal for these cards.

(FYI I am using CPUID to monitor the fan speeds. However, this seems bizarre behaviour and I'm wondering what the problem is. This in itself isn't a big deal as I don't use the PC for gaming and it's unlikely the GPU will ever reach above 60C (today it's running at 31C, and 26C with the 'default' cooling). So in other words the fans do work, but I only have the option of them running at a set speed or them not running at all. As soon as I deselect the fan curve option, the fans go off again.If I enable a fan curve the fans do come on, but only at a constant 1070-1080RPM.This option allows customizing fan curve at GPU firmware level instead of doing it entirely in software. If I uncheck Auto on Fan speed, it doesn't matter where I put the slider, the fans don't come on. Added 'Use firmware control mode' option to software automatic fan control module.This is probably OK too, as I heard they come on from 60 - 65, although maybe someone can confirm ? I've only had the PC a couple of days but so far they have never spun (aside from when using config in MSI Afterburner, see below), although the temp has been up to 60 when I did a stress test. On my new PC (which I had built for me as I couldn't get my hands on a graphics card) I've a question about fan speeds on the GeForce 3070.įirst, I noticed the fans don't spin under idle, which I know is a feature.
