I had an issue with my processor overheating even when using normal clocks with every cooler I tried. I tested the basic cooler, a homemade one, and a thermal contact pad 21. It was running at 98°C (200°F). Now it’s still getting hot with a water cooler at 4.7 GHz, operating around 80°C (175-180°F). This isn’t normal for the cooler I own (Coolermaster Master Liquid 240), which has a TDP of 210W. Other components include 10GB RAM, an Intel i5-1250H, and a 550W power supply!

If you've customized without altering the Vcore, you're likely drawing significant voltage from your CPU, which probably explains the high temperatures. Idle performance is low since speed-stepping is in effect, but during load it will require a lot of power. A 4.5 GHz configuration might be nearing its maximum capacity at those temperatures.

You're referring to the CPU's performance at regular speeds before moving to higher overclocked levels. The amount of RAM mentioned seems unusual, possibly a combination of smaller modules. How is the overclocking being done? What is the room temperature in your environment? The standard Intel processor shouldn't reach such high temperatures, particularly at default clock rates.

i'm pushing the bios just like everyone else, but i haven't adjusted the voltage. my room stays between 25-30°c, and i've got a corsair vengeance and three hyperx blues running at 1333mhz each. during idle, temps are around 30-50°c with my water cooler. at 4.5 ghz.

80c at 4.7ghz feels typical for adequate cooling. The result really depends on your vcore.

What exactly is that? Core voltage. You should look into overclocking guides if you're not familiar with it.

It seems like the BIOS is being adjusted for performance without changing the vcore value. This could be a quick tweak rather than a significant change.
