Note : The CPU average temperature can be expected to reach 95°C (203°F) under cool mode for the Alienware m15, m15R2, m17, and m17R2 computers. Example: Performance mode Example: Cool mode Alienware m15 R3 and m17 R3 Note: Reference this article only after the computer has been diagnosed with the onboard diagnostics (ePSA). CPU Performance Behavior on the Alienware m15 R3 and m17 R3 In general, the CPU frequency goes higher than Intel CPU's high frequency under Performance mode and Balance mode. CPU Model Name i5-10300H i7-10750H i9-10980HK # of Cores 4 6 8 # of Threads 8 12 16 Processor Base Frequency 2.5 GHz 2.6 GHz 2.4 GHz Fan control modes Full speed mode: The fan runs full speed to support the CPU operating at turbo frequency for a longer time. A noticeable fan sound can be heard. Performance mode: The fan runs aggressively to support the CPU operating at turbo frequency for a longer time. A noticeable fan sound can be heard. Balance mode: The fan runs in a moderate manner. Fan sound is less noticeable, but the period for the CPU to operate at turbo frequency would be shorter. Cool mode: The fan runs in a moderate manner. Fan sound is less noticeable, but the GPU and GPU performance is limited for better comfort and battery life. Quiet mode: The fan runs in a more quiet level than Balance Mode. Fan sound is less noticeable, but the period for the CPU to operate at turbo frequency would be lower and shorter. Note: Regardless of what mode, the CPU temperature can go above 99°C (210.2°F) and trigger a Thermal Event (TCC) under heavy load. TCC is activated and adjusts the CPU Power Limit 1 (PL1) frequency down by a couple hundred MHz. This decrease to the temperature rise allows the computer’s thermal control mechanism to catch up to the computer's best thermal performance balance. This is a general design of all gaming laptops. Verification Process First verify using the ePSA diagnostics that the computer has an overheating issue. Set the test environment and plug the AC adapter to the test unit. Open the Alienware Command Center (AWCC). Select the HOME Page on the Alienware Command Center main page. Set the thermal mode to Performance . Using the preinstalled Dell SupportAssist software, run the CPU stress test . Select the FUSION Page and monitor if the CPU Frequency and CPU temperature of Performance Mode CPU perform within the specifications of the below performance table.

Example: Performance Mode Example: Cool Mode Note: Third-party tools may show the temperature in red when the CPU T is greater than 90°C (194°F). However, being red does not indicate that there is an issue. When the Thermal Control Circuit (TCC) is activated at 100°C (212°F), it adjusts the CPU Power Limit 1 (PL1) frequency down by a couple hundred MHz. This decrease to the temperature rise allows the computer’s thermal control mechanism to catch up to the computer's best thermal performance balance. This is a general design of all gaming laptops. Common Questions Why does the computer Diagnostic Tool post High CPU temperatures in idle mode? When the computer is idle, the computer is not truly idle. There are background tasks operating in high frequency still, and they induce short period high CPU temperatures (less than 1 second). Then they lower down to a lower average temperature. Does the CPU get damaged when CPU temperatures reach 100°C (212°F)? No. The CPU operates well under the Intel CPU specification: Tjmax=100. (Intel) Processors supply a method (Digital Thermal Sensor or DTS) to report real time die temperatures below, equal to, or above the Tj(max). While the die should not typically run above the Tj (max), a temperature value above the Tj(max) may occur occasionally under normal operation. (Tj(max)=100) Why does the Diagnostic Tool post High CPU temperatures in a gaming application or a graphic stress application? Some gaming and graphic stress applications that are combined with heavy CPU activity causes high CPU temperatures. Is the CPU peak temperature under balance mode lower than under performance mode? No. Under Balance Mode, the CPU can still boost to its highest frequency in short periods and induce high peak temperatures. The CPU high peak temperature is expected when you set it to grab the best performance, no matter whether performance mode, balanced mode, quiet mode, or cool mode is chosen. Alienware Area-51m and Area-51m R2 Note: Reference this article only after the computer has been diagnosed with the onboard diagnostics (ePSA). CPU Performance Behavior on the Alienware Area-51m and Area-51m R2 In general, the CPU frequency remains higher than the Intel CPU's base frequency.

Cool mode: The fan runs in a moderate manner. Fan sound is less noticeable, but the GPU and GPU performance is limited for better comfort and battery life. Quiet mode: The fan runs in a quieter level than Balance Mode. Fan sound is less noticeable, but the period for the CPU to operate at turbo frequency would be lower and shorter. Full speed mode: The fan runs full speed to support the CPU operating at turbo frequency for a longer time. A noticeable fan sound can be heard.

The Intel eighth generation (Coffee Lake) processor supports a higher clock rate than seventh generation (Kaby Lake) or older processors. That means these computers noticeably generate more heat compared to any previous generation of computers. Because of this, Dell's engineering teams have designed the computer to tolerate higher temperatures.

You can get contact details from the link below: Contact Us Note : These computers are designed to maintain stability when the CPU temperature reaches a set temperature (termed the Thermal Control Circuit activation point). The Thermal Control Circuit (TCC) is activated and adjusts the CPU frequency down by a couple of hundred MHz to reduce the temperature rise. This allows the computer’s thermal control mechanism to catch up. The frequency never drops below the Base Frequency Mode. This slight drop in frequency can sometimes be mistaken for a performance drop. It is a design feature that is common to all gaming laptops. It helps to optimize the performance and prevent computers from exceeding 100°C (212°F). The TCC point for the following computers is: Alienware 13 R3, 15 R3/R4, and 17 R4/R5 - TCC = 97°C (206.6°F) Alienware M15, and M17 - TCC = 100°C (212°F) Alienware Area-51m R2 - TCC = 100°C (212°F) If none of the information above has affected or been responsible for your issue, there is another setting to check. The mode set in your Thermal User Profile can also affect the fan noise and the computer thermal temperature. Reference the mode types below and confirm that you have the mode enabled that works for you. All Models: Performance Mode: The fan runs aggressively to support the CPU operating at Turbo frequency for longer periods. The fan is noticeably heard to run. Balance Mode: The fan runs at a more moderate rate, which allows the CPU to operate at Turbo frequency for shorter periods. The fan is still heard but is quieter. Cool Mode: The fan runs slower and the fan is quieter, but the GPU and its performance are also limited to increase battery life. Quiet Mode: The fan runs slower than in balance mode and the fan noise is less noticeable than in cool mode , but the GPU performance is limited. The time that the CPU can operate at Turbo frequency would be lower and shorter. Alienware m15 R3, m17 R3, and Area-51m R2: Full speed mode: The fan runs full speed to support the CPU operating at turbo frequency for a longer time. A noticeable fan sound is heard.
