noisy fan, what is the clicking noise

[tyliseea]

i'm trying to figure out what's going with my laptop. the fan was noisy, and it used to click periodically (like it was overheating?)

so i thought to clean it. it didn't look dirty, but i cleaned it anyway, and put new thermal stuff between cpu and heatsink, put it back together....the fan still runs noisy after a bit (5mins or so?), and so hot it seems.

i'm thinking to get a new fan next, but does someone know what the clicking noise is, is it indeed overheating?

If it's a laptop there might be settings that help you save battery, try these and the fan won't have to work so hard.

Mine does that too. It'll be quiet and then run at max at idle. Laptops have a tendency to overheat, so it's no surprise most get hot doing nothing to begin with. It's just the fan going up in speed.
