High temperatures during OC i7 4770k with liquid cooling?
Hello everyone, welcome! I’m new to OC. Back in 2013 I bought a PC from ibuypower with the following specs: i7 4770k @3.5hz (with liquid cooling?) GA Z87 HD3 motherboard, 16gb DDR3 RAM, and a GTX 760 which I upgraded to a GTX 1060 SC. It’s been a while, so instead of upgrading my CPU, I went ahead and overclocked my current one. When I increased it to 4.0hz and 1.16V, I ran ASUS realbench for 15 minutes and the maximum temperature reached was 100°C. Obviously, that’s too high—people say it should be below 85°C. I checked online and saw many users with a 4770k using just a Hyper 212 evo bump to 4.4, achieving max temps of around 80-85°C. So I realized something might be wrong with my cooling setup, and honestly, I hadn’t changed the coolant in years. Should I replace it and how do I do that?
I also ordered a Hyper 212 Black Edition and some Arctic Silver thermal paste. Is this the better choice? Or should I address the liquid cooling issue?
Here’s a picture of my cooling system:

I would switch off the fan on the radiator and check if it warms up; if not, it suggests the pump isn't moving the fluid properly. That indicates a possible issue with the pump itself. It could also be related to the coolant inside, though I'm uncertain about its lifespan since old coolant tends to degrade over time.
It's possible your pump is no longer functioning properly.
You should be able to achieve around 4.5 GHz across the entire core.

when the pump is functioning properly, adjusting the fan settings on the controller can help. setting the CPU fan to 100% ensures continuous coolant circulation, while configuring the system fan to a higher fan 1 curve aids in cooling the radiator effectively.
Alright so basically my radiator is FILLED with dust for the past 7 years. I pulled everything apart and cleaned everything, and ran realbench at 4.0hz and 1.16V and the MAX temperature I got is 82C. Sorry for the trouble I caused lol
Anyways since that is stable, what is a good and stable hz and Voltage combo, that can last me for a long time. I am not really looking to push my cpu to the max, just a good balance between performance and lifetime for my cpu!?
well i would still make sure the pump is set to a fixed speed to ensure it runs at its best, since the cpu fan header is probably set for a heat sink rather than the pump by default. just checking that most pumps run at 12v unless controlled by software, and getting your fan on the radiator to work at its optimal level could likely lower the temperature. 😏
You can verify if it's operating at a consistent speed by monitoring its performance metrics or using diagnostic tools to ensure stability.
when you start up and access the bios, there should be options to manage fan speeds such as tapping delete. i would configure the cpu fan header to maintain a steady speed of 90% rpm for the coolant flow, and adjust the sys fan 1 header to a higher rpm to help the radiator cool more efficiently, thereby reducing coolant temperature.
