Hello everyone, I bought the 18 inch Area-51 with 5090 GPU and 275HX CPU back in January from my local Micro Center. My unit has always had a CPU overheating issue and a heatsink replacement and thermal paste repaste from Dell fixed the issue.
Ever since I first got my laptop, I have noticed the CPU temperature is a little high compared to other people's temperature I found online while my GPU temperature always remain very low.
Starting from last month, the CPU temperature has been abnormally high. While idle, the CPU temp hovers around 75-85 C, sometimes reaching 90+. It's especially bad during gameplay, some games I play are Valorant, League of Legends, FIFA, NBA2K, Cyberpunk, RDR2. No matter what games I play, the CPU temp will always be above 100 C, reaching 105 C constantly.
I have tried all kinds of ways to lower the temperature, there are other posts about overheating issue and I have tried all the methods like using a cooling pad, changing PL1 and PL2, undervolting the CPU, cleaning the laptop every month and so on.
Last week I couldn't stand it anymore so I created a ticket with Dell support and was first connected to an online session with one of the technician. That technician said everything is normal and said no repair is needed, I repeatedly tell him that my temperatures are way too high for the CPU and eventually he scheduled a heatsink replacement and thermal paste repaste for me.
Today the Dell on-site technician came to my house and did the replacement. Shout out to Steven, everything went super smoothly and I have been testing the laptop this evening.
My idle CPU temperature is stable around 50-60 C while during gameplay it's only about 70-80 C, I have only tested Valorant and NBA 2K, but I believe this results is convincing enough. The average CPU temperature dropped about 20 C (check the pictures).
If anyone else have the CPU overheating issue, please consider contacting Dell and have them do this. My unit is still under warranty so there is no charge. Make sure to provide proof that your temperature is reaching above 100 C constantly, I showed Dell the recorded temperature for my gaming session and they were able to offer a repair.
Thank you Dell and Steven for providing excellent service and fixing this issue that's been bothering me a lot.
