W520 loudfan3/20/2023 ![]() ![]() ↳ Forum Notices, Questions and Suggestions.FORUM RULES, HOW-TOs and FREQUENTLY ASKED QUESTIONS.this tends to be a "less is more" type substance in my experience. I hear Lenovo is a bit generous with their thermal paste use. how long do you think I can blast the hell out of my W520 at these temps before either the CPU, GPU, or fan bearing burns up? If the rest of you don't get temps like these I'm thinking I might have to crack the chassis open and re-goop everything. However there is noticeable fan noise now. TPFanControl immediately spun up the fan to 4500 RPM and the CPU is down to 85C and the Quadro is down to 70C. As davidhbrown mentions it is not optimized for the W520 but at least it kicks the fan into overdrive. Then I reinstalled my favorite old program from my T61p. Fan noise was negligible but the exhaust was HOT. Since some of the science apps are also compatible with nVidia Fermi GPUs like our Quadro 1000M/2000Ms I can get a good idea what this box runs like at full tilt.Īfter about 5 minutes of 8 threads running and my GPU maxed out, temps were at 95C on the CPU and about 75C on the Quadro. My preferred burn-in programs of choice are the various scientific research projects at BOINC in Berkeley - SETI, Milky Way, PrimeGrid, and the like. "Performance" for both battery and A/C), but it looks like they'd just the fan run more (more often and/or faster) - I'm pretty sure "Balanced" is the default that's where mine is for both.ĭoing some burn-in on my W520 and things are pretty toasty. There are probably better threads on this board for discussing that program.Įdit: There are also some thermal management settings in the BIOS ("Balanced" vs. I'm not sure I'd want to use it unless I knew it could respond to, say, a hot GPU while the CPU was somehow still relatively cool. It hasn't been updated specifically for the W520 logic board - when I tried it, it couldn't show more than an single system temp - but in theory it would allow a more carefully modulated response to temperature than the system BIOS. You can find a third-party program called Thinkpad Fan Control that allows you much more control over the cooling fan. If you go to the Power Options control panel, edit plan settings, click the advanced settings link, scroll to "Processor power management," open that group, then open the "System cooling policy" group you'll find you have two options: "active" (fan on pretty much all the time the default for many plans) or "passive" where the CPU will slow down to reduce heat before the fan will come on (the default for some battery/energy-saving plans). Pretty much, yeah, but it also depends on the power settings. Even after normalizing the file (the loudest signal is me speaking quietly), the fan is imperceptible and I have to turn the volume way up to hear my typing. I tried to make a recording of the full-speed fan, but the noise canceling on the internal microphone is too good. SpeedFan reports lots of temps, but no fan speeds. Manual speed 1 is about 2050 RPM and still close to silent. ![]() now it's saying 0 RPM which would certainly be hard to hear. In "Smart" mode, it drops it to RPM (less?) and I'm not sure I can distinguish it from the hard drive. At full speed, it's definitely noticeable, but not objectionable. I can hear the fan in a quiet room, but at idle it's quieter than typing on a keyboard. My SPL meter doesn't register below 60dB. When I set it to manual fan speed 7, it reports just under 4000RPM. TPFanControl 0.62 is reporting only one CPU temperature so I'm not sure I trust it (there should be 4 temps for the 4 cores, plus GPU, battery, ?), but at idle in BIOS mode, it's reporting a fan speed of a bit over 2700 RPM (docked). Good question not entirely sure how to figure that out. ![]()
