G551JW Replacing Thermal Compound?

post #1 of 7
Thread Starter 
Hello!

Nearly 1 year ago, I bought a G551JW with 960m 4GB, 4720HQ, 8GB RAM, SSD 128GB. I jumped from a GTX 670 (Desktop) to this laptop and I was really disappointed with the performance of it, now that I started to play more games lately, I started monitoring clock speeds and noticed insane thermal throttling. For example, CS GO which is known to be CPU limited game, actually is GPU limited for me even tho I play at 720p. The GPU starts at 1170 MHz and very quickly drops down to 540, sometimes to 405 MHz. I read about replacing thermal compound and this guy seems to have insanely good results with that - click.


I want to ask, as I still have warranty left on my laptop, does opening it voids the warranty? Anyone has had first hand experience with ASUS on that?

If it does void the warranty, would you recommend me doing this? I have 1 year and like 2-3 months remaining of my warranty.

What thermal paste would you recommend me to use?


Thanks!

Last time I opened up an Asus laptop it had tamper-proof stickers over the screws on the heatsinks that invalidated your warranty if they were damaged. Of course this was a while ago with an Asus G51VX-RX05

It depends on your country/support center, but here you can indeed repaste it and not loose the warranty IF you dont damage the board when doing the repaste.
Call/send them an email and ask about that, OR with care and pacience you can lift the sticker from the screw head and then put it back, you cant remove the whole sticker because it will tear, just heat it up a bit with an air drier from distance and start peeling away until you have it off from the screw head and a couple mm back.

The problem with that laptop is that is as zero ventilation grills..
If you want decent temps and get the expected performance from the 960m you will need to drill it..
Asus is going down the drain quality wise, and those "low" price ROG "gaming" laptops are just rebranded N series with black and red painting, they have coolers designed for 950m/850m gpu's and even those will throttle down.

But even repasting will only buy you a couple minutes before the stutter fest starts again, without drilling in the fan zone so it can pull fresh air its a lost cause.

Thanks man, awesome reply. +rep'd

And, I think it's the paste because I am looking at YouTube videos of how supposedly my laptop plays this or that game and it seems to play them a lot better than mine. Those videos could easily be fake, no way to know if it's played on this laptop, but yeah. Just seems weird for it to throttle down to below 850m. I got a friend with another ASUS (seems to have exact same cooling), he has same CPU but 850m and on stress testing, I start off a lot better than him, but after like 5 mins, I get lower FPS. =/

Is returning it to ASUS for repasting an option?

Yes, you can ask them to repaste it for you, but they will use the same paste, it might help.
And try to update your BIOS to the lateste version, they tweaked the fan profile a bit and it also helps.
And you can undervolt you CPU, it will help you a lot with the heat problems, you dont loose any cpu power, you just lower the voltage bit by bit till it crashes, up it a tiny bit and call it a day.
Install Intel XTU e start by lowering core voltage by 50mV and start from there, some people can get it down to -200mV and end up with a final CPU TDP of 25Watts vs the stock 45Watts, its amazing how low some can get.
