For most of the test, temperatures were no more than a mere 118-124 degrees.īut the CPU fan was excessively loud, as well.

With an HWiNFO-regulated maximum Noctua fan speed (which for the C14S fan is 1,250 RPM), this maximum temperature was reduced to a relatively amazingly low maximum of just 126 degrees. Without HWiNFO64 (with the un-regulated Noctua fan running at a mere 314 RPM under unadulterated Dell hardware), Dell's 15-minute 100% CPU stress test produced 184-degree F temperatures. and the imperative need for fan-speed-controlling software. So we can understand the very poor performance of the installation (just maybe 10 degrees cooler than the stock Intel cooler). My high temperatures with the Noctua CPU cooler were a result of virtually no air passing thru the Noctua ratiator at 314 RPM. This resulted in a fan speed of approximately 1,250 RPM, whereas the original pre-HWiNFO64 speed was approximately a mere 314 RPM. Once I had the fan nomenclature sorted out by experimenting with manual settings for each fan and listening for which fan ramped up or down, I used the manual fan speed configuration to turn my CPU fan up all the way. but I wouldn't assume the same applies to every system without knowing that this order is the intention of HWiNFO engineers.Ģ. On my system, the first listed (Fan 1) turned out to be the CPU fan the second (Fan 2) turns out to be the case fan. I had the side of my case off the whole while, and was ducking under the desk at the time with a stethoscope to identify which (ambiguously labeled HWiNFO-identified) fan was which. You don't want to be running very long in that condition. I am not sure that there is some hardware or other limitation which precludes running my PWM case and CPU fans at other speeds, but at one point, I found the far left setting actually resulted (in respect to whatever other conditions) in turning my CPU fan off. a) 0 at the left end of the slider, b) the mid-point of the slider, and c) the right terminus of the slider. When I first tinkered with the Manual fan parameters, I was a bit befuddled to find that my PWM Noctua CPU fan could only be set at three speeds. I believe a well-reasoned approach to configuring just one set of 'Custom Auto' fan parameters will produce the kind of behavior you might presume require multiple configurations:ġ. With the stock Intel CPU fan and aluminum finned heat sink, we had temperature spikes as high as 212 degrees F in sometimes several cores, and sustained temperatures of up to 195 degrees F under 15-minute 100% CPU stress tests. Our machine features an Intel i7-8700 6-core CPU. I have just installed a Noctua NH-C14S CPU cooler in a Dell Inspiron 5680.
