CPU overheating issues

So, I’m running into some pretty annoying overheating issues with my CPU. My idle temps are sitting above 40°C, and once I actually start putting it under any kind of load, they spike past 90°C... it even gets bad enough that my PC just shuts itself down sometimes.

I'm running an Intel Core i7-4770K with a Cooler Master Hyper 212. I've already given the cooler and the fan a good cleaning, and I even applied some fresh thermal paste. Plus, the case itself is clean and seems to have decent airflow, so I'm honestly stumped on what else could be causing this.

I'm attaching a screenshot from Core Temp taken about 10 minutes after I rebooted the machine following one of those sudden shutdowns.

You might want to double-check how you seated the CPU cooler... especially since the rig is totally dust-free and you used a fresh layer of thermal paste.

Everything seems fine with the cooler, I think it fits the CPU pretty well.

Maybe your cooler just kicked the bucket—like, the heatpipe leaked its gas or something—or maybe your motherboard is just reading the temps wrong...

The cooler is about a year and a half old now, so I’m really not sure how much life it has left in it, I guess. As for those temperature readings, the heatsink feels incredibly hot to the touch, and honestly, I can barely even get near the VRMs without feeling the heat. So, I don't really think the readings are fake or anything.

Were temperatures lower when they were running at the same voltage before?

It’d probably be easiest to run some tests using that Intel stock cooler if you haven't tossed it yet

If everything was running smoothly before and suddenly isn't, don't assume something broke on its own. It usually boils down to one of three things: you either applied too much or too little thermal paste, the mounting pressure is uneven, or there's an actual defect with the cooler itself—like a faulty base or a bad heatpipe—just like fadedorca66 mentioned.

So, I lowered the voltage and everything seems fine now. It's kind of weird though... since when is the default voltage 1.4?

Nah, I don't have one. This is my only cooler, I guess.

Everything seems alright on that front, really. But, now that I've dialed back the voltage, is there some kind of software I can use to monitor my CPU frequency under load? Afterburner is acting up on me for some reason.

You can actively monitor the clock speed through Task Manager by hitting
ctrl + shift + esc.
If you don't want to hover over that window constantly, you can rely on hardware info tools to log the minimum, maximum, and average speeds. Just a heads-up: make sure to disable any "cool and quiet" settings in your BIOS first. Otherwise, those power-saving modes might log an 800MHz idle state as your baseline, which completely ruins your data when you're trying to diagnose thermal throttling.

A second option while you're actually gaming is to fire up MSI Afterburner. If you head into the hardware monitoring section, you can enable clock speed tracking there—since MSI Afterburner uses RivaTuner for its monitoring overlay, it’ll show up right on your screen.

Many stress testing utilities also come with built-in graphing tools specifically designed to track clock speeds in real-time, such as OCCT.
