Yeah, the fans operate silently.

Amazing, did you do both fans? Are the fans hard to disassemble and add the lithium grease too? Apart from an SSD upgrade I have not messed with much laptop hardware.

Hi No need to replace the fans. A friend of mine recommended a product for getting rid of the rattling noise, which worked wonders in my case. It is lithium grease, that costs about 4 dollar a pound, you can buy it in any auto parts-, or DIY store. You have to apply a really tiny amount, where the arrow points to, then put the fan back in its place. And that’s it. Been using it for about a month now and it is completely silent.

Thanks for this tip, is it still working?

I bought mine in March (i5 version with MX150) and has been working great. The “normal” fan noise on the latest bios was better, in my case I don’t do heavy load most of the time and whilst travelling I use the battery saving mode which means passively cooled (no noise whatsoever). The problem was when one of the fans started making grinding noises, which was solved temporarily by applying grease. After few months it started making noises again and the one on the other side too. I ended up purchasing 2 replacement fans from Aliexpress and replacing both today, and I am so glad I did as the noise has gone back to normal. The replacement fans had metal blades rather than plastic ones, I am not sure if that would make a difference. On the battery, I get 6 to 7 hours during normal usage, and 9 ish on battery saving mode (no MX150 and processors running at 1 GHz tops). I don’t regret the purchase of the price, I love the keyboard, the screen and the speakers. I install a 970 512 SSD and it flies since, although I am still running to original OS in the original drive. Cheers

Hey I also have this grinding noise, only started recently, it pisses me off so much! Are your replacement fans still working? Were they hard to fit? Have you got a link to where to purchase?

Thanks

Thanks man.

I tried this but it didn’t work so then I contacted the manufacturer and figured out my monitor does not actually support HDMI 2.0 so 4k/60 over HDMI is not even possible, only 4k/30 is possible, so the only way to get 4K/60 is over mini display port.

So what I think I need is actually this, which is basically the same as the other choetech HDMI adapter but supports mini display….

According to benq that model should support 4k60 8bit over HDMI. Yeah I think it uses the onboard graphics by default, but for heavy graphics it should automatically switch to rendering on the mx150, similar to how the internal display works (as far as I know). Now that you mention it, I remember I did have to make a custom resolution profile in the intel graphics control panel for my display specifically. I think it was with CVT-RB 3840×2160 and then try 60hz or 59hz if 60hz is buggy.

The thing is when I try and output from the cheotech adapter to the HDMI of the monitor, 4k60 is not even an option. Which makes me think the HDMI’s on my monitor dont actually support 4k60 maybe? Or that i’m not using an HDMI 2.0 cable maybe?

It is also not possible to get an hdmi to mini display port adaptor that works in that direction, it only works if you are outputting from a mini display port to an hdmi monitor, not the other way round. So not sure how this will work. Im sure it would work with a usb-c to mini display port cable but then i cant charge at the same time..

Honestly I’m not sure, you’d have to try it out. Are you sure the HDMI port on your display supports 4k60? My display only has two 4k60 ports and two 1080p ports, so it might be a specific port or your display might only support it through dp mini. And is your hdmi cable high speed? Some of the older HDMI cables dont support 4k60.

Yeah i mean it says its 4k60 not sure about the hdmi cable. I think it maybe only supported through dpmini. This is the model of monitor…

On the Notbeook pro is it correct that it is using the onboard graphics not the mx150?

Hey guys, been following this thread. I bought he cheotech adaptor but it can only output at 4k30 to my monitor over hdmi. When i check setting it says it is using intel integrated 620 to output, is this correct?

I have had problems displaying 60hz on my 4k monitor before using hdmi, so had to use the mini display port. If i get a mini display port to hdmi cable then connect to the cheotech that way do you think that would work?

 

Thanks
