Laptop Fans - besides cleaning, is it possible to get better RPM's with oiling or something?

MSI Raider GE75 - specifically the 10SE model (thanks Costco!)

 

Working well, but fans should be at 6000+ RPM on their 'full speed' mode.  Have cleaned them out a few times and get better temps/results and short of repasting (which I'm not inclined to do right now) is there anything I can do to get them back to their original 6000+ RPM's?  There are (2) fans one on each side and currently after last cleaning one is at 5500~ and the other at 5200~.  Am I doing it wrong? lol...

 

Oiling?

Swapping seems like huge project for little return investment . . .

 

Anyone have experience with this kinda thing?

If you can remove the fan blade from the pin it rests on you can try cleaning the pin. That would probably make a bigger difference than oil, but u could try adding a tiny bit of oil at that point if you want to.

Bit of a late response, but the main way of getting a higher speed out of those fans typically lies with either software or a BIOS update. I would definitely start there.

Scalling with rpm is not linear i don't think that from 5200 to 6000 rpm their a big airflow difference. And normally fan without oil spin faster till they heat up and seize.

Cleaning the fans, oiling them, and re-timming the heatsinks always helps.....well, until its too late and it doesn't.  

 

If the motor itself is starting to wear, no you'll never get the RPM's back.  If the above doesn't do enough, it MIGHT just be about time to do a full replacement.  Up to you of course, I mean its still working at 5200RPM, and you'd likely see a better temp drop from a TIM change than getting those extra 800 RPM's back.

While this is not a "helpful" post, your talking of fan improvements for me thinking of the below video. Problem is, it may make your laptop a little loud.

Did u monitor the rpm at full tilt when u first bought the laptop?  If so what was the original max rpm?  I'd replace the fans if u feel they aren't pulling rpm like before but u can tell if there is damage to the bearing if the fans are hard to turn by finger or feel any friction.  I would personally replace them and if u don't have a software option to force to full tilt while under load or creating a custom fan profile.  Just snip the PWM wires, the blue wire usually or u always have a red positive wire, a black ground wire, a yellow rpm sense wire, and a pwm wire could be green but usually is blue just cut it and forget about it on both fans if u cant control the fans by software in the operating system.  This will yield peak performance on the CPU & GPU on all tasks all the time.  Good luck
