Clevo stuff is consistently available on taobao, AliExpress and eBay. The tradeoff being lower cost and higher risk of going direct, and more listings and availability on the Chinese sites, vs the buyer protections of sites like ebay.

 

Availability can often be the overriding feature of such niche parts and sourcing them.

 

BennyG my DM3 running my 1060M at 52 C and hot spot 58, mucked around with heatsink foam a bit .
Interesting your watercooling didnt change the DM3 temps much, the vapor chamber is a big piece of copper to offer a large cooling are and vapor volume.

I run fans full speed whenever laptop working, seems silly not to.

My intention of the ebay item was I think the DM3 heatsink is the best laptop cooling solution out there, and should be a upgrade kit for all the P870 series.

I have been experimenting with typeA mxms (older ones, had a couple of spares) so needed to remove 2 of the heatsink doublers on the DM3,
they are easy to remove with a stanley knife blade and a tiny hammer tap. Interestingly when I put the type B back in with 2-3 layers of thermal pad, it ran nearly 5 degrees cooler.

The doublers are held on with a silver adhesive (eg araldite like glue), was thinking that might be easier than soldering (BennyG), if I knew what that adhesive was !!!!!!

BennyG Quote from ypur DM3 water mod IMGUR

"MK1 the loop Shifted a bit even after left overnight... I think there was something wrong with the glue (Artic Silver Adhesive), it didn't set as quick as other tubes of AS epoxy I've used in the past. It usually sets very quickly, <10min. It is also easy to flick up the stray bits with a razor blade. Completely unlike normal epoxy. On the upside it'll be easy to remove and clean in prep for solder, that's for sure. <= later when removing this, it came apart waaaaaaay to easy, there was definitely something wrong with the glue."

Any other adhesive you have tried ?

The TM offers better VRM cooling and core cooling for the CPU. This is more important with a 6 or 8 core CPU.

 

The single best CPU modification you can do is a direct die vaporchamber mod. With it you should have a lot more overhead for OC, granted you have the TM1 heatsink as it has more heatpipes and VRM heatsink. Check out brother @ole!!! post about it here, which features a direct die frame and soldered vaporchamber.
