Help to diagnose temperature problem on X201i?
Hi all, so I have an old X201i (bought 2011) and it's running ok but the bottom side near the exhaust fan (see image below) is getting quite hot even at idle, while the rest of the laptop seems 'normal' temperature. Checked actual temperature readings using HW MONITOR (attached) with very few apps running. Any ideas on what the real source of the problem is, and what to clean/replace if opened up? Thanks in advance.
