Gaming on Laptop Dust: Life and Performance- 1/24/2023

Let’s be real: most gamers rely on performance and higher usage frequency to achieve success and move on to the next level. These are two factors to take into consideration when discussing why a computer, specifically a laptop, should be periodically cleaned. And I’m not talking about PUPs, bloatware, viruses, or other software stuff. I’m talking about hardware and dust and debris accumulation. And you can “game” the accumulation of dust at some point!

Here’s an example case

Last week I had a client come in with a high-end ASUS ROG gaming laptop. He complained about higher than normal operating temperatures, especially under higher than normal GPU loads. In my process of diagnosis, I opened up his laptop and noticed both the CPU and GPU fans were caked with dust, and the GPU fan was not spinning. My conclusion was that rather than clean the fans and heatsinks, the best plan of action, being that the GPU fan was bad, was to replace both the GPU and CPU fans. Most fans have a lifecycle, and it’s my belief that if a laptop has two fans, it’s always best to replace them both at the same time. They are rather inexpensive. This saves you the cost and effort of replacing the other fan shortly down the road. The client agreed, and we proceeded with the quotation for the work to be performed. In terms of fan replacement, traditional productivity laptops are fairly straightforward. However, higher-end gaming laptops are a bit more difficult and involved. There are multiple theories we can come up with as to why the GPU fan failed, but two theories come to mind in this case. 1.) The fan simply reached the end of its lifecycle. 2.) The buildup of dust and debris caused excessive heat and resistance on the fan. I’m more apt to think #2 was the case here based on the overall age of the laptop.

Not every case is the same

Now, I’m not saying that every case will require fan replacement. In most cases, you’ll only need thorough dust removal within the chassis. Taking a can of compressed air and blowing it through the laptop vents is absolutely the wrong approach. This just moves the dust around the inside of your computer, which blankets the motherboard. It can also cause dust to wad up in the fan’s spin zone, causing an obstruction. Doing the job the right way involves opening up the laptop chassis and disassembling down to the motherboard level, removing the fan(s), cleaning the fan(s), removing the heatsink, cleaning the fins on the heatsink, and removing and reapplying thermal grease to the GPU and CPU. We then reassemble the laptop and run it through a benchmark test to monitor temperature levels.
