I fixed the PGG27UQ Fan noise...

[TrevorR]

After using the monitor for close to a year, it has gotten to the point where the fans speed up and slow down constantly. My monitor is perfect, no backlight bleed or dead pixels so instead of submitting for an RMA and getting another panel. I decided to see if there was dust in the fan that I could clean up, so I took off the back panel.

Nope, fan is dust free.. So I took off the Gsync module and disassembled the fan.

Why did ASUS use poor quality thermal paste? It literally peeled off like a sticker and did not *have any type of consistenc whatsoever nor was it completely covering the chip... It was dried up.. My Monitor has a build date of August 2019 so its a little over a year old.





I put some noctua thermal paste and spread it evenly on the chip itself and then put a dot of it in the center for good measure. Using the monitor as I type this for the past 6 hours, the fan is quiet now. I kind of forgot how quiet it used to be.

Hello, nice job mate! My fans on the same LCD gone a little wild so I used RMA and they clean out all dust and fans are now silent, but your way is so good too.
Can you provide more pictures of disassembly back plastic plate and G-sync module? I was wondering about how to remove too but I was so afraid of damagind these covers.

Thank you.

This article has some teardown shots of the insides. I'm interested in doing the same with my PG35VQ, not sure what the differences are inside but I imagine the G-Sync module is largely the same. I wonder if changing out the fans helps too? Looks like they are mini-PWM headers for both the top (intake I think?) and the exhaust over the heatsink.
