i7 4790k 1.188v 4.5Ghz temps
Following some undervolting because of elevated stock voltages and heat, I performed stress testing on AIDA64. However, the temperatures remain slightly high, particularly when comparing to similar configurations with identical voltages and clock speeds. After about 12 minutes of AIDA64, my maximum temperatures were recorded as follows:
CPU: 71°C
Core 1: 83°C
Core 2: 87°C
Core 3: 85°C
Core 4: 76°C
I have three intake fans—two positioned at the front and one at the bottom. The CPU cooler is a Corsair H100i GTX with the pump set to performance mode. There are two GTX 980 cards running at 40% fan speed, plus an additional fan for exhaust in the rear.
I recently bought some thermal paste and plan to replace it soon. I’d appreciate any advice if others have faced similar issues with their 4790K units. I’m confident my cooler is functioning properly and all fans are operating, but the temperatures still seem elevated compared to previous levels before the undervolting (they reached 90°C even during gaming).
Thank you in advance!
Do you have a place for the radiator to allow cool air to flow? If the CPU runs at its default speed and temperatures remain high, there will be serious problems. It might only work with forced air from the case if the radiator is fitted, or the pump could begin to fail.
The radiator is positioned on top of the case with the stock Corsair fans. The CPU runs at 4.5Ghz as mentioned in my initial post. I haven’t found a reason for this issue, so I’m changing the thermal compound to check if it improves things. The temperatures stay within the values I recorded, so it doesn’t seem like the pump is faulty.
It seems the exact wording wasn't included in the message. I only see the title, not the full content.
No worries man. I understand the CPU is fine even at these temperatures; I’m just curious if there might be air bubbles or poor contact with the block. I’ve cleaned my radiator and all the filters on my case. Thinking about where this chip ended up, I’m already quite satisfied—but everyone else with the same settings running ~20°C lower is puzzling me. If the thermal compound switch doesn’t help, I’ll likely switch to another cooler.
I don’t have your specific data, but I’m happy to help you figure it out. Let me know if you’d like guidance on checking your CPU temperatures or comparing them with others.
Aquielisunari shares his thoughts with confidence. He believes the CPU is safe despite the temperatures and questions about possible air bubbles or poor contact. He mentions cleaning the radiator and filters, and expresses satisfaction with the current setup compared to others using lower baffle temperatures. If thermal compound doesn't help, he plans to try a different cooler. He also asks about his own CPU temperatures during idle, gaming, and full load, noting idle ranges of 33-40°C, gaming up to 66-72°C, and full load in his initial post.
Nichaa: Aquielisunari: Nichaa: No problem, man. I’m sure the CPU isn’t in any trouble even with these temperatures. I just thought maybe there are some air bubbles or poor contact with the block. I’ve cleaned my radiator and all the filters on my case. Thinking about where this chip ended up, I’m already quite satisfied, but everyone else with similar settings running ~20C lower is puzzling me. If the thermal compound switch doesn’t help, I’ll probably just replace it with another cooler. What are your current CPU temperatures when idle, while gaming, and under full load? Are you asking about these voltages and clock speeds? Idle temps are 33-40°C depending on the core. Playing Battlefield 1 at maxed settings goes up to 66-72°C. Full load was in my first post. I’m assuming the stock settings. At 90°C after overclocking, gaming? Another H100i user had similar issues – you can check their answer here: So far, I think the issue is with the cooler installation and the variability of the silicon. Motherboard? CPU temps: 71°C Core 1: 83°C Core 2: 87°C Core 3: 85°C All at 100%? Check Intel’s Burn Test I linked to in the previous question.
Aquielisunari responds with a detailed analysis of the situation.
Nichaa replies with further questions about CPU temperatures under different conditions.
They seek information on stock CPU temperatures during idle, gaming, and full load, as well as voltage and clock settings.
Nichaa clarifies that 90°C is the target operating temperature and mentions past experiences with similar issues.
They also reference cooler installation and silicon variations as possible causes.
Motherboard is not mentioned as a factor in their current concerns.
Nichaa replied to the same question, expressing confidence that the CPU is safe despite the temperatures. He questioned whether air bubbles or poor contact might be causing issues, despite cleaning the radiator and filters. He noted the chip's location and compared it to other users with similar settings but lower temperatures. Nichaa mentioned past experiences with thermal paste changes and suggested considering a different cooler if the problem persists. He also referenced past temperature concerns for the H100i model and questioned the reliability of stock cooling solutions.
