PC fan revs up while accessing Revit material library

[jackieg]

Anyone else experiencing their workstation fan "revving up" like it's been cleared for take off while accessing the material library in Revit? I have had a DELL tech on site a few times to replace the fan, but wondering if the community has found a fix for this, or an explanation as to why it is happening.  Thx.

Hi,

I have the same issue (non-issue for me) with my workstation. After watching my CPU usage I see that a process called "AdPreviewGenerator.exe" quickly increase CPU usage from around 6-8% all the way up to 97% for several seconds and then ramps back down. The description of this process is "Autodesk Material Preview Generator". I have a I9-12900K so it takes a bit to really stress it like that, however it is only for a couple seconds so it doesn't worry me.

After a quick google it looks like this is normal(ish) and that if you want to avoid it you can change your browser type to "Text View" instead of showing the previews. Apparently it has to load all the textures every time you open the browser, hence the high CPU usage. 

Hopefully this helps.

Can you adjust the fan curve in BIOS? What are temps, rpm and frequency on the fastest core when that happens? 

I think Intel uses a tool like XTU to see CPU activity. Use HWInfo to  monitor fan speed and temps

What happens is that one or multiple cores speed up to execute your task. that produces heat and heats up the CPU. That will increase fan speed. it is all normal. the only thing you really can check is see if the fan curve is too high (fan runs faster than it actually has to). Those CPUs can run at 95°C. So no need to try to cool them to much less under load if the noise is killing you.

Both of my work computers rev up and down all day long. It is to be expected but some fans are louder than others. I used to joke with my neighbor when I heard his ramp up, asking him if he was just getting around to getting something done.

@jackieg 

its called Rev it...so its literally doing what its name says Rev'ing the fans of your workstation up 😄 

Initially it was called "Charles River Software" but as they were not able to evolve past the single core processing issue, and CPU fans went nuts with every new feature they added, they must have had no other option but to rebrand it to REV IT .
