Question Asus FX553 weird fan behaviour

[vipa415]

Got my hands on a FX553VD (GTX1050, 7300hq, 8gb ddr4) asus laptop. The fan (theres only one) has some problems, sometimes the BIOS cant read the fan speed rpm, reporting N/A. When that happens, the laptop fan ramps up violently and then is stuck there. This doesnt seem to happen all the time, the problem went away for one day after rebooting the unit. The fan problem came back, i opened the laptop, cleaned off in there and re-attached the fan connector to the mainboard. Fan has been behaving normally since, but i assume it is going to be a re-appearing problem. Would replacing the fan-unit resolve this issue? I was thinking it might be the fan-controller/sensor being bad (temperatures display correctly)- I have no idea though if replacing the fan-unit would resolve this issue.

its not a windows/OS problem, whenever it happens, its also doing it in the BIOS. temperatures seem OK-ish for a laptop, GPU is cool (below 70 at all times), CPU can reach above 80 while gaming in a warm room (sunlight on it aswell).

Any ideas?

Above 80C is Abbey Normal, your CPU likewise should be 70C or lower at peak operation.
If the controller is on MB, you're screwed. But you can try getting a fan that is above specs. in CFM (cubic feet per minute).

Over 80c is too high to feel safe for me aswell. Though ive never had a (gaming) laptop posting low temps (70 or below) when CPU heavy gaming or tasks, atleast sustained). Also laptop is in a 30+ degree room with direct sunlight close. With ThrottleStop ive managed to undervolt by 124mv and things are much better now (less throttling, more consistent, and better temps too).

Not too much the temperatures im worried about, im going to limit most games to 60fps or below anyways which makes the CPU not run as fast. Its the fan-speed trouble i had, it hasnt been a problem for 5 days now (since i reseated the fan-cable to the mainboard), but im not sure if that truly has permanently fixed the problem as the fan-cable was solidly attached to begin with.

I am not a fan of overclocking, it's just a quicker way of burning your PC.
Have you considered a fan pad ? Something like this: https://www.amazon.com/TopMate-C11-...9Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=

Not a fan of laptop-overclocking either. Im only undervolting, the GPU ran at around 1680mhz (nvidia max boost for the 1050). So i undervolted the GPU. sank the temps by around 10c celcius. The GPU is set at 1645mhz at around 0.950v.
The problem is MSI Afterburner does seem to take up too much system resources, CPU is active more and ThrottleStop reports a 30watt usage instead of 21watts just by starting ThrottleStop just doing CPU tests like prime95 and TS bench.
