Razer Blade 18 (i9 14900 HX) CPU temperature overly high.

Less than 1 year old Razer Blade 18. Using HWMonitor show CPU temperature hovering between 80c-90c during idle, and reach 100c easily if i starting even Chrome. 

 

Cleaned the fans and its cooling system (use compressed air) and no change.

 

Setting the system performance to low on Synapse still not helping. 

The upper case is hot to touch but the exhaust from fans is just slightly warm.

 

 

Does the system have issue with the physical heatsink itself?

Other than this, any other possibility of other fault? Hardware, software?

The system was running without issue until 2 days ago. 

 

Thanks!

    Hello evervisionDandelion665,

    Thanks for sharing your concern here. I understand that your Razer Blade 18 is overheating, with high CPU temperatures even during idle. Aside from cleaning and adjusting performance settings for your laptop, have you also tried the troubleshooting in this article? If the same problem persists, please PM me and help me gather the following information below:

    • Have there been any recent software updates, installations, or changes to system settings around the time the issue started?
    • is there adequate ventilation around the laptop, or is it placed on a surface that may block airflow, like a bed or couch?
    • Are there any processes using an unusually high amount of CPU resources, even during idle?
    • Does the laptop exhibit any other power issues, such as rapid battery drain or unexpected shutdowns?

    Also, fill in the following:
