I have an issue with my laptop, it's always overheat, I have already clean the area of the processor and heatsink that will be the place where I put the thermal paste, before applying them, but whenever I use the laptop it's always in overheat situation.

My laptop is Lenovo Ideapad 100 14 IBD, Im running at

Windows 10 Home 64 bits Intel i3 5005u RAM DDR3L 2GB on board + DDR3L 4GB Kingston KVR16S11/4 SSD SATA 256GB

When I using the laptop on overheat situation, the air flow that came out from the fan doesn't even feel warm, then I check the heatsink, it's was super hot, but the heatsink near the fan doesn't even hot, I just wonder why this could happens, I already tried to clean the paste thermal area, clean the fan and even use an vacumm cooler.

  • A CPU heatsink is supposed to be warm. What behavior exactly made you believe your system is overheating?

  • Is the fan running? Did you connect it properly? See: youtube.com/watch?v=9Qh0SA3LB6o . Then make sure it was put together properly.

  • the heatsink that near the fan, it doesn't even warm, as the youtube video that @john mention, the heatsink shape like a pipe that curved long into the fan exhaust. I'm using core temp, then detect that the core temperature reach 100 deg celciuls.

  • While the heatsink part above the processor are hot, its seems like the heat doesn't transferred through the heatsink pipe

  • I playing few game like dota 2, which in low preset usually hits 40fps, but it constanly dropping from 40fps i count about 2-4 seconds its drop to 2-10fps, after 5-12 seconds it up again to 20-40fps and will drop again after 2-4 seconds. Not only on the game, every time my processor reach 100% usage about 2-6 seconds, its will became really laggy

While the heatsink part above the processor are hot, its seems like the heat doesn't transferred through the heatsink pipe

It appears that heatsink may be defective; for the procedure to check/replace the heatsink cooling pipe(s), see: Dell Precision 7510 overheating heatsink diagnostics (Part 1)
