Will eliminating dust filters influence laptop temperatures?
Hello, I'm looking to take out some plastic mesh from the lower cover of my Lenovo E560, which I think are dust filters for the fan. I was considering this because I want better airflow and cooling, though it might not make a big difference if performance isn't a big issue. I'm curious—will removing this filter actually affect temperatures? Has anyone else tried similar changes on laptops? If it helps, I plan to just take out the filter right under the blower fan so more air can flow freely. I know this isn't a high-performance gaming laptop, and maybe the idea is as impractical as cooling a notebook's heatsink with water. Please share your thoughts.
These aren't filters; they're just physical grills meant to keep debris out. Taking them off would be risky and offer no advantage. It's better to periodically blow them out using compressed air from a compressor or can. Just avoid letting components freeze. Short bursts are more effective than continuous airflow, which can cause frost buildup.
Clearing out the dust from a blocked filter will impact the cooling efficiency. Taking out the filter is unlikely to make much difference, and it may actually reduce performance since more dust will gather in areas it shouldn’t have reached before. In short, the fans in laptops don’t move enough air to cause this restriction under normal settings. I’m curious about removable dust filters—have you seen any examples? Would you mind sharing a picture of what you mean?
I get it, the temperatures stayed the same when I flipped my laptop over. Based on what you said, it seems like taking out the plastic mesh wouldn’t really help either. Here’s the photo with the blower marked in red:
Other vents on the left of the red square are exhaust, below that are passive vents for RAM or alternate airflow for the fan.
The plastic pieces embedded in the paint are likely fixed and well-secured, so they wouldn’t stop me from trying anyway. Also, note that this image comes from a teardown video, not a detailed breakdown of my device.

Yes, I understand that they aren't a dust filter. I'm not overly concerned about debris or dust, but Thinkpads must function in any environment while maintaining performance.
Since eliminating it won't improve airflow, I believe it's best to leave it as is and maintain cleanliness. Thanks for your responses.
I know I own an HP Envy m6 and experienced some thermal problems right after purchasing it. I disassembled it completely, thinking it might have a faulty paste application or airflow obstruction. Nothing turned out that way. I replaced the paste but saw no improvement. I opted to modify the chassis as you mentioned, but since the grills were already part of it, I used a Dremel to open it up again after another disassembly attempt. This change had no impact on cooling performance. It seems the design was inherently inadequate for some CPU models in such confined spaces. That’s the full explanation.
Of course, I've already applied some fresh paste and performed a thorough cleaning. Removing a small amount of plastic shouldn't solve my issue. I wonder if the outcome would be similar if I followed your approach.
