75-90°C on Performance mode while gaming is a different story. That Ryzen 9 7845HX can pump out some serious heat under load, and in a relatively confined laptop chassis, those temps aren't entirely unexpected during demanding games. However, the fact that it's always above 65°C on AC power, even in Silent Mode, is a major red flag. This points to a fundamental thermal problem, not just expected behavior under load.
1) BIOS Updates:
- This is often overlooked but crucial.
- BIOS updates can contain significant improvements to power management, fan curves, and overall thermal tuning.
- Check the ASUS support website for your specific model and make sure you have the latest version.
- Sometimes, these updates address specific heating issues.
2) Armoury Crate Settings:
- ASUS's Armoury Crate software gives you control over performance profiles and fan speeds.
- Dig into the settings:
3) Operating Modes:
- Make sure you're actually in Silent mode.
- Sometimes, a simple restart or a glitch can cause the system to default to a higher performance profile.
4) Fan Curves:
- This is where you can fine-tune fan behavior.
- Experiment with creating a custom fan curve that ramps up fan speed more aggressively at lower temperatures.
- This might increase noise, but it could significantly improve cooling.
5) Windows Power Plan:
- Check your Windows power plan as well.
- Make sure it's set to "Power Saver" or "Balanced" when you want lower temperatures.
- A "High Performance" power plan will keep the CPU running at higher frequencies, generating more heat.
6) Ambient Temperature:
- This is a factor you can't control easily, but it's important to consider.
- If your room is already hot (above 25-30°C), your laptop will struggle to dissipate heat effectively.
- Consider using a cooling pad or improving ventilation in your room.
7) Blocked Vents:
- This is the low-hanging fruit.
- Make absolutely sure that the intake and exhaust vents on the laptop are not obstructed by anything.
- Using the laptop on a soft surface like a bed or couch can block the vents and cause overheating.
Now, here's the crucial part: You mentioned it's been like this since you bought it. This almost certainly rules out thermal paste degradation over time. It points to one of two things:
1) Factory Thermal Application:
The thermal paste might have been poorly applied at the factory, creating air gaps and reducing heat transfer.
2) Design Flaw:
The laptop's cooling solution might simply be inadequate for the Ryzen 9 7845HX, especially in a thin and light chassis.
Re-pasting could fix the first issue, but as mentioned before, it's risky and could void your warranty.
Therefore, my strongest recommendation is to contact ASUS support immediately. Document everything: screenshots of temperatures, Armoury Crate settings, BIOS version, etc. Explain the problem clearly and firmly. If they try to brush it off as "normal," insist on escalating the issue to a higher level of support. If the laptop is still under warranty, push for an RMA. This is a manufacturing defect or design flaw, and you shouldn't have to live with it.
