If you not having any other airflow issues it sounds like the pasting of your CPU is not done correctly. You are correct that the cooling should support the turbo mode. Mine does as well as many others
As I said, the fan is too slow. I presume its the increase in temperature of the CPU cores which is supposed to speed the fan up, so I doubt that its anything to do with the Heat Transfer paste. What temperatures does yours reach? I use "Core Temp" to record max temps.
- first - download Throttle Stop - there you can disable Thermal Throttling
- second - if you want to manage fan - download HWInfo, and you have "Fan Control" option which works with Dell 3793. You may choose between 0, 2400 and 4800 rpm
I feel you, OP. I’ve been fighting the same thermal insanity on my Dell.
PL1/PL2 settings on these laptops are… a joke—PL1 at 22 W and PL2 at 51 W, which is actually more than the adapter can even supply.The BIOS is ridiculously restrictive: every time I try to push PL1/PL2 to sensible levels via QuickCPU or HWINFO, the system just blows past my settings.
It’s incredibly frustrating—feels like I don’t even own my hardware.
The fans are way too slow, the heatsink is laughably small, and yes, temperatures approaching 100°C are “normal”—if by “normal” you mean the CPU throttling itself to avoid frying.
You can reduce temps by limiting PL1/PL2—20 W for sustained loads and 30–40 W for bursts works well—but anything higher just panics the VRMs and EC.
Through some weird testing with benchmarks like 3DMark, I’ve noticed even small things—like wallpapers in Windows 11—can impact CPU scores while leaving the GPU almost unaffected. It’s hard not to get angry, because it feels like the system is designed to push you toward buying a newer “AI PC” instead of letting you control what you already own.
One practical thing that really helps: debloat your operating system. Cleaning out unnecessary background processes and bloatware noticeably improves CPU temps and stabilizes performance under load on this Inspiron 3793 with the i7-1065G7. For me, this makes a bigger difference than it probably should, but it’s one of the few levers we actually have.
At the end of the day, fan curves and monitoring software only go so far. Controlling power draw and cleaning up the OS are the only real ways to keep this laptop from panicking under normal use.
P.S.: One of my favorite debloat tools is Chris Titus Tweaks—just a PowerShell script you run, no problems whatsoever. It’s perfect for a power user and optimizer like myself.

I have 2 solutions for you:
- first - download Throttle Stop - there you can disable Thermal Throttling
- second - if you want to manage fan - download HWInfo, and you have "Fan Control" option which works with Dell 3793. You may choose between 0, 2400 and 4800 rpm

if there is dust near the fan , just blow it up with a hair dryer
