Intel Core i5-4590 stuck at turbo speeds constantly

So, just like my title says, my Intel Core i5-4590 stays pinned at its max turbo clock speed all the time.
Basically, when I’m just idling—you know, just browsing the web or sitting on my desktop—it really ought to be down around 800 MHz. Instead, it’s constantly running at 3700 MHz, and honestly, it's starting to worry me. I realize the clock speeds are supposed to ramp up once I launch a game, but seeing it sit at full turbo while I'm just staring at my desktop is... well, it's a bit much LOL. I'm genuinely concerned here; is this going to fry my hardware, or is something else going on under the hood? Help me out!

Go into the BIOS, load the default settings, or just find the turbo boost option somewhere in there.

Since you didn't specify which OS you're running, I’m going to assume you're on Windows 8 or Windows 10, so give this a shot... You can find that specific window by navigating to Power Options -> change plan settings -> change advanced....

To be honest, I've never actually messed with my BIOS before, so I'm not really sure what could possibly go wrong by changing things.

Just because you haven't messed with your BIOS settings doesn't mean everything was perfectly configured right out of the box.
In the BIOS, you usually have the option to toggle Turbo Boost—though, if I recall correctly, it’s pretty much just an "enabled" or "disabled" choice. Honestly, there isn't any real reason to turn that off.
You should also check if Intel Speedstep Technology is toggled on within the BIOS. That feature is designed to scale down your multiplier when the CPU isn't under heavy load, which helps keep things efficient.
But look, there's a very good chance that neither of those settings is actually your issue—it's more likely that your CPU is simply running at max clock speed because it's actually busy. Just because you're staring at your desktop thinking you aren't doing anything doesn't mean there isn't some process spinning away in the background!
Try opening your Task Manager and taking a look at the Processes tab to see if any specific task is hogging the CPU (look for anything where the CPU column isn't sitting at 0%). If you stumble upon a process that looks suspicious—or even just unfamiliar—and you're not sure if it's safe to kill, try right-clicking it and selecting "Go to service(s)." This will pull up a list of all active services, highlighting the ones tied directly to that process. From there, you'll probably need to do a little bit of light Googling to figure out what each service actually does and whether it's safe to stop them.
It is also entirely possible that you've accidentally picked up a Bitcoin miner or some other nasty little program that's constantly taxing your processor. I'd recommend running a scan with Malwarebytes just to see if that clears things up.
