I recently acquired the Phanteks PH-TC14PE to enhance my CPU cooling without needing a watercooling setup. I've read reviews from tweaktown and other sites suggesting idle temperatures around 27°C and load temps between 55°C and 60°C. Yet during my tests with MSI Afterburner, I've observed these readings.

I've already conducted some research and re-applied thermal paste using 91% isopropyl alcohol, applying just a small amount a few times. The improvement was minimal, only 1-2°C. I've also enabled XMP in BIOS and set my CPU OCd to 4.4 GHz.

Expecting these higher temperatures? My voltage is 1.19V.
My fan speed on the PH-TC14PE is set to about 500 RPM. I attempted to increase it to 1000 RPM, but the temperature remained unchanged and exceeding 1200 RPM was too noisy.
Additionally, I noticed the heatsink of the PH-TC14PE is slightly scuffed and scratched when I first opened the box. Could this be contributing to the temperature readings?
Thanks!
75C on a 5820k OVERCLOCKED TO 4.4GHz is excellent. I think you had a lucky outcome if anything. Depending on the thermal paste you use, you might achieve even better performance if you switch to a higher-quality one (especially if your current paste isn't very good).
Mr Kagouris:
75C on a 5820k OVERCLOCKED TO 4.4GHz is fine. I think you had a good chance if anything. Depending on your thermal paste, you might achieve better performance by switching to a higher quality one (especially if yours isn't already very good).
I understand. I’m okay with these temperatures, but I was a bit let down by the results compared to what reviewers showed. Right now I’m using the Phanteks PH-NDC paste, which seems to be of decent quality.
I think the TIM on your CPU is a bit below average.
However, these are 100% safe temperatures—it's regrettable you have such a powerful cooler but not better performance.
Do you believe it's safe and/or worth voiding your warranty to replace the TIM with aftermarket paste? Will your results change significantly?
No warranty? That's confusing. Swapping the TIM between the CPU and cooler won't cancel any guarantees. It might seem like a prebuilt unit but it doesn't appear that way. Regarding the thermal paste, Phanteks PH-NDC does seem quite good, so you probably won't notice much change unless you switch to a metal paste. Those are risky if not done right because they conduct electricity. Overall, you should be satisfied with these temperatures. Better temps might come from a premium AIO water cooler, but they're costly and make a lot of noise.
Mr Kagouris:
Warranty void? That's a question. Swapping the TIM between the CPU and the cooler won't cancel any guarantees. Perhaps if your build was factory assembled but it doesn't seem that way. Regarding the thermal paste, Phanteks PH-NDC appears to be quite good quality, so the difference won't be noticeable unless you switch to a metal paste—those are risky if not done right because they conduct electricity. Overall, you should be satisfied with these temperatures. Better temps might come from a premium AIO water cooler, but those are costly and can make a lot of noise.
Right, but I'm referring to removing the CPU cover and changing the TIM between the heatspreader and the chip. It can be dangerous since the CPU might get harmed.
Alright, I'm proceeding with this change. Delidding the CPU and swapping the TIM between the heatspreader and the chip itself is possible, though it carries some risk of damaging the CPU. I'm doing it now, using liquid metal pro between them—it's quite extreme and might harm the CPU. Are you okay with trying another one? If yes, it should help keep temperatures stable between cores. This won't lower core temps directly, but it will stop one or two cores from overheating consistently. I have a specific core in my 3930K that runs about 7°C hotter than the others, which is why I'm taking this step.
I understand the situation, but I need to clarify that removing the CPU and swapping the TIM between the heatspreader and the chip can be dangerous. It might harm the CPU. I’m proceeding with this change, using liquid metal between them, which is quite extreme and could cause damage. Are you okay with this approach? It should help balance temperatures between cores, keeping core temps stable without lowering them too much. However, I’m not sure if it’s the best path since my 3930K already runs significantly hotter than others. I might prefer sticking to the default settings first.

Warranty void? Not really. Swapping the TIM between CPU and cooler won't cancel any guarantees. Perhaps if your build was factory assembled, it might not seem that way. Regarding the thermal paste, Phanteks PH-NDC does appear to be quite good quality, so differences won't be noticeable unless you switch to a metal-based paste—those are risky if not applied properly because they conduct electricity. Overall, you should be satisfied with these temperatures. Better temps might come from a premium AIO water cooler, but those are costly and tend to be noisier.
However, I'm referring to removing the CPU and replacing the TIM between the heatspreader and the chip. That can be dangerous as it might harm the CPU.
I think the i7 Extremes are permanently attached to the IHS. The 115X models usually have poor TIM. The paste change I mentioned was between the cooler and CPU, which isn't really necessary since you already have a solid thermal paste.
