Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Why does my computer make grinding noises when using UE4?

Some really weird stuff is going on inside my PC when using UE4. I have never had this issue with any other application before.

When using certain parts of UE4, my computer (or I guess, harddrive) is making "grinding" noises. The noise differs from what parts of the application I use, which is absurdly strange.

At first, this just sounds like my harddrive dying. But I'm starting to question it, since it doesn't make this noise in any other application, even when using the same harddrive.

That's some weird ass sh*t. Does anyone have a clue what's going on?

The same thing happens to me! The noise even varies depending on which panel my mouse is hovering over. Super strange. I feel like my computer is dying. I have an intel i7 liquid cooled cpu, 16 GB of 1866mghz ram, and a gtx 780 nvidia graphics card, so I know my computer can handle it.
My gaming laptop also makes weird noises when using ue4.

Whats going on?

This buzzing noise when in the UE4 editor is happening to me as well, but only with my home PC, which has much more powerful hardware than my work PC (and this issue has not arisen when using UE4 on that). I remember something similar when playing either Rust or DayZ; I'll have to verify which one that was.

There are a number of posts that describe this same or a similar issue (links below), all dated 2014 and newer. Seeing as this is happening with my fairly new and powerful PC build, I'd be very curious to identify any hardware similarities in others' PCs that are encountering this issue.

Perhaps someone at Epic could organize a survey on whether they've experienced this and requested data collection on hardware specifics of the users, so we may be able to identify a pattern. It seems Epic really cares about their users, and I'm sure all of us would really appreciate the effort.

As it makes me a bit nervous to keep using UE4.

Interesting. That is a horrible noise in that video. Thank god my noise doesn't sound like that. My noise is more of a 'static'. My best guess is that it sounds like I can hear the electricity going through my processor, like a buzzing sound. And the sound varies depending on where my mouse actually is. Hovering over the content browser makes the worst noise.

Yeah. Its a common thing with coil whineing, i think its because of the fps change in ue4. My friend had that problem with stalker call of pripyat, every time he hovered over something the frequency of the whine changed.

I think you are right Ballistic. After carefully listening, I believe it is coil whining.

Have a great day badRadley

I hope this can be of help to someone else as this was very annoying for me, but turning off Realtime Rendering (CTRL+R) in the viewport has removed the coil whine (definitely coming from the PSU and only with UE4 in the Editor).
