Weird Temperatures on CPU (OC)
Weird Temperatures on CPU (OC)
I just put in an AIO water cooler with my CPU and before that I was OC'd to 4.4 GHz on air (Hyper 212 evo) on my i5 6600k. With that setup I had around 70-80 max load temps and 30-40 on idle, expecting much better performance from the cooler. I tried pushing it up to 4.7 GHz but the temperatures keep going past 90 and I’m not sure if that’s normal, even at 4.6 I’m seeing temps as high as 87.
I apologize for the misunderstanding. It seems an intake radiator would be the optimal choice for installation, and I wouldn't alter your current configuration.
Consider lowering your overclock to the pre-AIO level and observe the results. If performance doesn't improve compared to the 212 Evo model, there may be issues:
1. Thermal paste distribution
2. Faulty pump
3. Air pockets in the system
If the first issue occurs, use a thermal paste syringe, a cloth, and cleaning alcohol to inspect the CPU block for gaps between the paste and the AIO CPU.
If the second issue arises, contact customer support with an RMA. You should hear the pump operating normally, but if it's silent, press on the block and feel for any unusual sensations.
people generally assume AIO water coolers are instant solutions, but the truth varies. the model you're using matters—single radiators perform better than air coolers for overclocking, while bigger ones allow higher temperatures. however, pushing hardware to its limits brings it closer to its thermal ceiling, making it hotter. for instance, my I7 4790K reaches 95°C at 4.7, but only around 80°C at 4.6. i chose 4.5 for my overclock because it handles full usage during gaming without overheating. i also use a 240mm radiator with four fans.
The Paladin:
people usually assume AIO water coolers are magic solutions. First, which model you have matters—single radiator units aren’t much better than a top-notch air cooler when it comes to overclocking. Bigger models can handle higher temperatures, but pushing the hardware closer to its limits makes it run hotter.
For instance, my I7 4790K struggles at 4.7, but stays around 95°C. At 4.6 it hits the mid-80°C range. I chose 4.5 for my overclock because it lets me use full capacity during gaming (up to 100% usage) without overheating, even when it reaches about 80°C.
I also use a 240mm radiator with four fans inside the case, and two exhaust fans on the back and top. I know they’re not perfect, but I just hoped for a stable 4.5 GHz without overheating, given my air performance of around 4.4 GHz.
The 240mm AIO in push-pull setup should follow circles around the 212 evo. For instance, switching from Be Quiet! Dark Rock Pro 3 to a 280mm push-pull with front intake led to a 10-15c boost in load temperatures on my i7-6800k. Start with the same overclock settings as before, then check the temperature changes. Even a small increase of 100-200MHz on the CPU can noticeably affect the heat levels. Also, consider the radiator placement carefully—mounting it improperly, especially if the GPU exhausts heat into the case, can cause serious problems.

A 240mm AIO in push-pull configuration should orbit around the 212 evo.
For instance, switching from the Be Quiet! Dark Rock Pro 3 to a 280mm push-pull (as front intake) resulted in a 10-15c boost in load temperatures on my i7-6800k.
Start with the same overclock settings you used for the air cooler, then check the temperature differences. Even a modest 100-200MHz increase on the CPU can cause noticeable changes.
Also crucial is the radiator placement. If your GPU vents all its heat into the case, a top-mounted exhaust radiator could be problematic.
My setup has the radiator in front of the case and only two fans—what fan arrangement do you recommend?
Oh, my mistake. I misunderstood. An intake radiator seems like the ideal choice, so I won’t alter your configuration.
Adjust your overclock to the pre-AIO level and observe the results. If performance drops compared to the 212 evo, check these points:
1. Thermal paste distribution
2. Pump malfunction
3. Air pockets in the system
If 1 appears, use a thermal paste syringe, a cloth, and cleaning alcohol to inspect the CPU block for gaps where paste isn’t properly applied.
If 2, contact the manufacturer—silent operation suggests an issue.
If 3, gently shaking the AIO should dislodge trapped air bubbles. Each AIO contains air; the problem lies in its quantity or placement.
