![]() I would disassemble the laptop, and possibly tape around the CPU with painters tape. Liquid metal performs best when you have very high quality component finishes and generally liquid coolers with high mounting pressure for the waterblocks. On a socketed chip you can remove the cooler and then remove the chip. I would never, ever, ever, recommend it on a BGA (soldered on) chip as removing it you risk it spreading to other components. Liquid metal is dangerous and mostly a gimmick. The point of regular thermal compound is to fill in those gaps and make up for that. The CPU normally doesn't make ideal contact wiht the heatsink, and that's because it wasn't designed to be the best possible. OEM PCs are not built to very strict tolerances, nor to the highest contact pressures. You've been watching too much YouTube, and Thermal Grizzly is one of the biggest sponsors of tech YouTubers. Steps are fine imo, but you can still dump LM from the start, seems pointless and thermal paste under normal conditions (proper contact) should do just fine.Įdit: btw from the pictures the gap between the die and cooler plate is towards those pads (there's more paste there while the other half of the chip seems paste-less, it had contact). However if that cooler extension where the screw goes through alreadu touches the screw nut that's on the PCB then there's not really much more room to further "push" it downwards, i.e. When the screws and plate are in the same direction the washer can be added between the screw head and cooler extension for the same effect. They just add a washer on each screw on the bracket effectively causing the plate that is on the other end of the pcb to come closer since the screws are now pulling it harder. Washer method is something that some people use on GPUs to increase mounting pressure on the die. TL DR: Liquid metal not cooling laptop correctly, what is wrong? So the questions going through my head are: Did I do the liquid metal application wrong? Did I overtighten or undertighten the screws of the heat sink to the CPU? Are the thermal pads on the capacitors in the way, causing a gap between the CPU and the heatsink? My conclusion is, is that the CPU is not making proper contact with the heat sink, thus the liquid metal cannot do its job, but to me, it seems like I did the application properly. That did not help much.Ĭurrently, my laptop's CPU is at 55'C - 65'C when using Chrome with no video playing - the ambient temperature is 21'C.When playing a 4k video for 30 min, the CPU temp instantly shoots up to 94'C and then fluctuates between 75'C and 95'C over the 30 min. I put a 4k YouTube video on for 30 min in an attempt to further "settle" the liquid metal. After the fans ramped up, the temperature dropped to 55'C. The problem is I saw that the temperature instantly shot up to 95'C. I turned on the laptop again and with a sigh of relief, it booted to Windows. So I decided to wait a few minutes for the liquid metal to "settle". I was very careful with my application so I knew this was not the case. I got a very big fright thinking I spilt some liquid metal on the motherboard and fried something. I closed the laptop again and it wouldn't boot. I removed the thermal paste and applied liquid metal - Thermal Grizzly Conductonaut - see pictures at the link above. This weekend I opened up the laptop and took a look under the hood to see that the stock thermal paste was not properly applied and that half of the CPU had no thermal paste on it. Laptop: Lenovo Ideapad C340-14IWLCPU: Intel i3-8145U 2.1 GHz (2 core, 4 threads)iGPU: Intel UHD Graphics 620 I am trying to fix the problem by replacing the thermal paste with liquid metal. While at these high temps, the video stutters. streaming a video), my laptop's CPU temp shoots up to 93'C and stays there until I close the application.
