Linux Vst Plugins

Hi all,
I have been working with OBS for a few weeks now and habe been pretty amazed by its features so far. Congratulations to the developers!
The only thing that has been bugging me is the fact that, when running OBS, the fan of my workstation is getting annoyingly loud at times. Of course, I can easily filter that noise out of the recorded stream in a post-processing step: I determined the frequency of my fan to be somewhere between 700 and 900Hz, so I just use a Band Reject filter and all is fine.
That post-processing step, however, needs a lot of time, so I have been wondering, if it's possible to apply a Band Reject filter during recording. Sure, the Noise Suppression filter in OBS does a good job, but if I set it as high as needed to remove all fan noise, the overall audio deteriorates quite a bit.
So, I found the possibility of using VST plugins (I'm pretty new to all this audio stuff). I'm working on Linux, so I do know that there might be a few problems getting that to work, but I'm dedicated to trying it. In a nutshell, my problem ist that the entry 'VST 2.x Plug-in' that's mentioned in all the tutorials doesn't turn up, when adding a filter to my audio signal. I'm using 19.0.2, so it should be there, shouldn't it? I even reinstalled another version from git... still no luck. I put a few of the VST files ('.so') in the correct directories (following this page: https://github.com/jp9000/obs-studio/wiki/Filters-Guide), I even installed Carla (http://kxstudio.linuxaudio.org/Applications:Carla), thinking that OBS might maybe require a host application to be installed... still no luck.
Any ideas as to what else I could try to get the VST plugins to work? Or are there other options for adding a simple Band Reject plugin?
Any help would be much appreciated.

A list of open source VST (and other format) plugin/app projects. The intention of this list is to catalog open source plugins or apps which are fully featured or are useful examples which have non-trivial features.

Linux

To a degree, VST support under Linux already exists. The FST and DSSI projects provide utilities to open and run Windows-specific VST plugins. Those projects do work, but they are dependent on WINE. ABOUT LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform.

The main benefit of having Open Source plugins/apps is that the code itself is preserved for the future, so when the author(s) stop updating it the community can continue using and developing the software. Open Source projects are also a great way to learn how different audio FX/instruments are created.
