Linux way way slower than Windows?
So I jumped ship from Windows to Kubuntu last night, and It's mostly been pretty good. However my general performance of the computer has been abysmal. Like it takes upwards of 5 seconds to open anything. All of my hardware seems to be running at max speeds, so I have no idea why it would be so sluggish? It's as if I'm running on 2gb of ram and a cpu at like 1.5ghz. My specs are:
i7-8700k at 4.7ghz max Amd Rx 6750xt 16gb ram at 3200mhz Linux is on an m.2
Any ideas? This is practically unusable for any normal operations, let alone any gaming.
Update: So it seems like my CPU is being throttled to it's min of 800mhz because the temp is just below 100c. Not sure why it's so high because I never got that high even in intensive gaming on Windows

Are your AIO fans, pump, etc. connected to the motherboard or through a USB hub?
OP this comment could be a major clue to whats happening with your AIO.
I have some fans connected via hub, but the pump and aio fan are connexted directly to the motherboard
That would be where I'd look first. A lot of AIO manufacturers only write drivers for Windows. There's an old Reddit thread that has a few things to try. If this is your first dip into Linux get used to googling things. A lot of things. Ubuntu or Kebuntu are great OS to start on because there is always a forum post or a Reddit thread that deals with exactly what you're dealing with. Once you are more comfortable I'd move onto Linux Mint or straight Debian. All those nice things that make Ubuntu easy to learn will eventually also hold you back.
If your AIO pump came with a hub you likely need to use it instead of plugging directly into the Mobo.
As an example my corsair AIO came with a hub and i didnt want to use it. Finished my build and found out i absolutely had to use it in order for the device to work properly.
Do you know what model AiO you have? Some models report pump speeds as higher since they have multiple magnets triggering the RPM sensor, so the 1600 might actually be 800 or even 400, which is way too low for the pump.
I would try setting the pump (and AiO fan) to 100% speed in the Bios for testing. Some pumps work well with a fan curve, some don't.
Edit with more technical details: Normally each revolution should generate 2 Pulses on the rpm Feedback wire. But Pumps don't always follow this spec so might over or underreport their actual rpm.
Look up CoolerControl I use it for my Corsair AIO, and my CPU cooler runs entirely off a USB header. But CoolerControl also supports motherboard headers.
You can use it to make custom fan curves and check pump/fan speeds.
