How to: Fix for Dell G7 Over Heating – Dell G7 Cooling Advice

Important I am not affiliated with Dell and this is my personal experience with overheating issues on the Dell G7 17″. I am not paid by Dell and bought the Dell G7 17″ outright myself. If you find this helpful and want to say thanks, please buy me a coffee. It keeps this page ad-free. Thank you!

In our home, we have a 17″ Dell Gaming Laptop. It’s one of Dell’s G series gaming laptops, the step before you go to Alienware. It has great specs for the price but is prone to overheating.

I’m going to outline three things that may help you fix the problem. They have made a difference to us and we hope they help you too. The range from the basic to advanced. I don’t give any guarantees and I can’t provide you technical support if you try anything, this information is provided “as is” in the hope that our experience helps other owners.

I do recommend using HW Monitor to benchmark temperature performance. HW Monitor is especially helpful if you’re concerned about thermal throttling of the Dell G7.

Bonus: Dell G7 Memory Upgrade Tip

I have had a few people email me since I originally posted this asking if I have upgraded the memory on the Dell G7. The answer is yes! I have and it’s not difficult. I now run using 32GB of Memory from Crucial, but you can get it on Amazon. It’s about a 15-20minute job to upgrade the memory on the Dell G7. You do need to remove the back panel but it’s all standard screwdrivers. You will need a guitar pick or prying tool to remove the back panel.

3 Dell G7 Cooling Options to Stop Overheating

There are essentially 3 options for cooling your Dell G7. There are instructions or reviews below on each. I have had success with the first 2 and I know good quality thermal paste can make a difference, so it’s worth considering even if it’s more technically advanced.

  1. Upgrade the BIOS
  2. Use a Cooling Pad
  3. Replace the Dell G7 Thermal Paste

I recommend you try each of these in order, just to cover all your bases. The combination of a cooling pad and thermal paste will give you the best results.

Option 1: Dell G7 Drivers and BIOS Updates

The best place to start is ensuring you have the latest drivers and BIOS updates. These are typically automatically installed through Windows Update or the Microsoft Store. If you factory reset your Dell or removed any of the default software, you can download the official drivers here.

As of June 2020, the latest BIOS version for the Dell G7 is and it was marked as an urgent update.

It’s also really important to have both the Alienware Command Center Application and the Dell Power Management Software. Together these apps help balance performance while maintaining a more stable operating temperature.

Option 2: Dell G7 Cooling Pad

The Dell G7 fans are located more at the rear of the laptop, making it tough for the laptop to get good airflow. So I cooling pad is a must. So finding the best G7 Cooling Pad requires a bit of trial and error. The right cooling pad does make a difference and we had more luck with an unknown brand we found on Amazon.

We first used the Targus Chill Pad but it was not effective. Personally, I would not recommend the Targus Chill Pad and we only purchased it was in stock and because we could get same-day delivery. Never again. The Dell G7 still suffered overheating issues with the Targus. The problem with the Targus Cooling Pad is the 2 fans are underpowered and noisy. We “retired” the Targus pad. The Targus Cooling Pad was so bad we did not even get around to benchmarking performance – I mean if the laptop still overheats and shuts down, that’s all the benchmark you need. Also worth noting that the Targus has no USB pass-through, so you lose a USB port or you will have to run it from external power and it has no on/off switch.

Next up we tested the KLIM Laptop Cooling Pad. We had never heard of the brand but size-wise it seemed like a good fit. We opted for the one with white LEDs because while you can’t turn them off and the lights felt more subtle. It’s also the best-sized cooling pad for a 17″ Dell G7. This is because of the 4 fans on the KLIM, 2 are mounted further back and almost directly under the Dell G7 fan intakes. This is workable, even if the KLIM Cooling Pad is slightly smaller than the size of the Dell G7. One major observation of the KLIM is that it is whisper quiet, we leave it on all the time because you can’t hear it running.

I have benchmarked Dell G7 using a cooling pad in the results below. Please remember your results may vary because it really depends on your ambient room temperature, general laptop airflow, etc.

I will update this from time to time with any other cooling pads I test. If you make or sell Laptop Cooling pads and want me to test and benchmark its performance on cooling the Dell G7, contact me.

Option 3: Dell G7 Replace Thermal Paste

This is for more advanced users and I am not a lawyer but it could void your warranty. We have not taken this step, but it may be worth considering as a last resort. There is a how-to apply thermal paste on the Dell G7 video embedded at the end of this post.

You can remove the large blue heat sink inside the Dell G7. You will require the following

  • Prying Tool or Spudger, this is the cheapest  iFixit Prying Tool
    The prying tool is absolutely needed for opening the case. It is also useful (but not necessary) to remove disconnect the fans during the process but if you are careful, you don’t need to disconnect the fans.
  • Isopropyl Alcohol, you can get this one but if it’s out of stock, try this one.
    This is needed to clean off the factory default thermal paste. You’ll also need a roll of paper towels, but I am assuming you have that already.
  • Thermal Paste, Arctic MX-4 is my recommendation
    This is one of the better thermal pastes on the market. I have yielded good results on my fanless Raspberry Pi 4 and it’s got a good price to cooling ratio.

You will also need a screwdriver set.

Steps in the process, again a reminder this may void your warranty and I accept no liability.

  1. Disconnect from power.
  2. Remove the back panel on the Dell G7.
  3. Disconnect both fans (optional) from their power cable using the prying tool
  4. Unscrew and remove the fans.
  5. Remove the heatsink, following the numbered order (there are number markings at each screw point)
  6. Clean the old paste off the GPU and CPU chips and the large blue heatsink with Isopropyl alcohol.
  7. Carefully apply the Thermal paste.
  8. Reassemble.

Again, we haven’t done the above because we’re concerned it may void the warranty on our 17″ Dell G7 even though overheating is a problem. This YouTube video by SRC Tech does show you how to do it. According to reports, you can reduce the temperature of the Dell G7 by 5°C/9°F with Arctic MX-4 thermal paste.


I hope these tips helped you, if you’re using a different cooling pad and have had more success let me know.

I have not tested using free tools like ThrottleStop to adjust CPU power consumption. It’s easy to use but personally not a fan of this because testing for stability can be a nightmare. If you want to use ThrottleStop, this site has a good overview of how it works or watch this video. Just remember that if you use ThrottleStop you will need to also schedule it to run every boot (use Task Scheduler).
