In the heat of the summer, I usually enjoy having a fan blowing on my desk. But I’m not so keen on the fan inside my laptop blowing at top speed. It seems like a sign of distress, especially if I don’t know the cause. There are several reasons why your computer fan might start blowing at top speed, ranging from blocked air vents to malware. Most likely, your CPU is just doing some very intense calculations and needs to dissipate the resulting heat.
But recently I’ve experienced high fan speeds when I’m not asking my computer to do anything in particular. I have the usual Adobe apps open but I’m not working on any documents. One reason this might be happening has to do with Creative Cloud Libraries, which do a lot of their work in the background.
As this article on Adobe.com describes, you can use the Task Manager on Windows or Activity Monitor on macOS to try and root out the issue. If you find that the process called CEPHtmlEngine Helper is using most of your CPU capacity, then CC Libraries may be the culprit.
The article details two possible solutions. One involves fixing permissions for a log file, and the other will have you doing a little brain surgery inside the Adobe application packages to replace some folders related to CC Libraries. I performed the latter on my machine and haven’t seen the fan issue since.
You need to replace the contents of this folder.
The Adobe article (dated March 2019) also mentions that they were planning to address the problem in a future update, though I went through all the release notes since then and didn’t find mention of it. In any case, if your computer’s fan inexplicably seems to think you’re working in the middle of the Sahara desert at high noon, try the fix in the Adobe article.
