CPU temperature

[Mahmoud_1st]

I noticed sudden instability in the laptop processor, as it reaches from 40 to 100 degrees Celsius in one second(Without pressure like opening one tape in browser ), with throttling and severe performance interruptions. I tried running a new Windows and changing the thermal paste twice with two different brands, and the problem still exists. I have owned the laptop for exactly one year and two months.

@Mahmoud_1st,

Welcome to our HP Community forum!

Thank you for sharing the issue with your HP Victus laptop. Based on what you described -sudden jumps in CPU temperature from 40°C to 100°C within a second, even when idle -it is highly unusual and points to a possible hardware or firmware-level issue. Since you've already reinstalled Windows and changed the thermal paste twice, we can likely rule out software or thermal paste application as the cause.

Here are some possible causes and suggestions:

---

Possible Causes:

1. Cooling Fan Malfunction

   • Even if the CPU and GPU cooling fans look clean, one or more may not be spinning properly or at all.

   • Use tools like HWiNFO64 or HWMonitor to check fan RPM in real time and see if they ramp up when the CPU heats up.

2. Improper Heatsink Contact

   • Even with good thermal paste, if the heatsink is not aligned properly or there is uneven pressure, the CPU will overheat quickly.

3. BIOS or Embedded Controller (EC) Firmware Issue

   • Sometimes a buggy BIOS or EC firmware causes incorrect fan control or power management.

   • Check HP’s support website for your model and see if a BIOS update is available.

   • If the problem started after an update, try rolling back to an earlier BIOS version if possible.

4. Defective CPU Sensor

   • The internal temperature sensor in the CPU might be faulty, which can cause incorrect readings and sudden throttling.

5. Power Delivery or VRM Issue

   • A fault in the motherboard’s power delivery system can cause voltage spikes, leading to overheating.

---

Recommended Actions:

• Check live temperatures and fan RPMs using HWiNFO64 (Sensors Only mode).

• Enter BIOS setup (press ESC or F10 at startup) and see if the CPU temperature jumps there too. If yes, it confirms the issue is hardware-related.

• Try using the laptop without the battery (AC power only), in case the battery is affecting power delivery.

• Make sure you’re using the original HP power adapter with correct wattage.

---

Final Suggestion:

Since your laptop is just two months out of warranty, I strongly recommend contacting HP Support Egypt or try HP Support. If the issue is due to a defective fan, sensor, or motherboard component, HP may offer a goodwill repair, especially if you explain all the troubleshooting you’ve already done.

Kind Regards,

I only suspect them.
Defective CPU Sensor
&
Power Delivery or VRM Issue

What's the solution?
I contacted one of the warranty branches, and they told me they only accept devices with valid warranty.

@Mahmoud_1st,

Based on your suspicion of a defective CPU sensor or a VRM (power delivery) issue, and since HP Egypt has declined out-of-warranty service, here’s a practical path forward:

---

Step 1: Confirm the Hardware Issue:

Run HWiNFO64 (free tool — Sensors Only mode):

• Check if CPU temps instantly jump (e.g., 40°C → 100°C in one second).

• Look at “Distance to TJMAX” — if it suddenly drops to 0, thermal throttling is being triggered.

• Watch CPU Package Power and Vcore — are there sudden surges?

• Observe fan RPMs — are they responding normally?

Enter BIOS (ESC > F10 at startup) and stay there for 5–10 minutes.

• If temperatures still jump without any OS running, that confirms a hardware-level problem (CPU sensor, VRM, or motherboard fault).

---

Step 2: Repair Options (Out of Warranty):

Option 1: Trusted Local Technician:

Ask a qualified repair technician to:

• Inspect the VRM circuitry — unstable MOSFETs or chokes can cause overheating and throttling.

• Test the motherboard for abnormal voltage spikes.

• Reflow or replace faulty components (VRM or sensor related).

---

Option 2: Replace Motherboard:

• Open the laptop and note the exact motherboard part number (P/N) — printed on the board itself.

• Search for a replacement on eBay, AliExpress, or local repair shops.

• This may be more cost-effective than buying a new laptop.

---

Option 3: Re-escalate to HP Egypt via Social Media:

Others have successfully received help just out of warranty by doing this:

• Contact @HPSupport on Twitter/X or HP Middle East on Facebook.

• Kindly explain:

  • You're only 2 months out of warranty.

  • Severe throttling due to suspected CPU sensor or VRM issue.

  • You've reinstalled Windows, repasted twice, and tested in BIOS.

• Request a "goodwill repair" or a paid repair quote, citing all your troubleshooting efforts.

---

Summary:

Unfortunately, truth be told -at least based on my own anecdotal experience, it appears to me that your laptop likely has a hardware-level fault -either a failing CPU temperature sensor or unstable VRM components. Since HP Egypt isn’t accepting out-of-warranty service through normal channels, your best options are:

• Visit a local technician for advanced motherboard diagnostics.

• Consider replacing the motherboard using the correct P/N.

• Contact HP via social media and ask for an exception or paid repair.

Please keep me posted!

I don't think the motherboard is faulty.
Take a look at this I posted a while ago.

Spoiler

There are illustrative pictures in my profile.

I suddenly noticed instability in the CPU temperature after a year of using the laptop for studies and programs like Matlab. The temperature used to not exceed 70 degrees, but now it's reaching 100 degrees.

I changed the thermal paste the first time (the gray one). After the first week, the instability returned, reaching 100 degrees frequently with thermal throttling.
I installed Windows cleanly and updated the BIOS, but the problem persisted.

I changed the thermal paste again (the blue one, a different brand). After the first week, the instability returned, reaching 100 degrees frequently with thermal throttling.

I noticed the paste shifting away from the CPU and GPU.

I visited two different specialized centers twice, and they stated that there was a problem and I needed to go to the warranty center. I found out that the warranty had expired.

Please reply

Is this normal ?

[NonSequitur777]

@Mahmoud_1st,

No, that doesn't appear to be normal -let alone desirable.

I have given you all the feedback/recommendations I could come up with.

Have you actually pursued these recommendations?
