Front case fan stopped spinning for while

[Robinskix]

Alright so i woke up 2 days ago and noticed my Front case 200mm fan wasn't spinning I gave it a light love tap and it started spinning at its regular rpm. My hard drive temperature usually is 30 degrees on idle and load since it never spins down but that day it was 33 degrees celcius. my ssd was 24 degrees as usual.

It the fan has been spinning normally again for 2 days since and the temperatures in my case are normal aswell. Also the fan hasn't made any wierd noises either

Temps are celcius
cpu idle 35 and 44 load
gpu idle 30 and at 100% load its around 75 degrees with a fan profile of 80%
room temperature is around 22

Is the fact that the fan wasn't spinning that day something i should worry about? And what could be the cause? There is no dust in the fan and it gets cleaned monthly. Sorry for asking this but I havent been able to keep it out of my mind since. I do have a fan controller on the fan and i can speed it up and slow it down as normal. Should I be worried?

I wouldn't be too worried about case temps. Your fan is either on its death throes, or your fan isn't getting enough voltage. Without giving the fan a love tap, does speeding up the fan through the fan controller make it come back to life?

I turned of the pc and started it again and the fan spins itself up on its own.I haven't had to give it a love tab since it stopped. The fan controller basically just slows it down or speeds it up. It doesnt turn it off or anything. I usually have it on the lowest setting for noise purposes. But if i speed it up in the controller the fan does speed up.

All fans have a "stall voltage", where below that threshold, they just don't have enough power to move the fan. 200mm fans have quite a high voltage threshold, since the motors in them aren't often as beefy as they should be in fear of high noise and power consumption. Your fan controller probably doesn't have a stall voltage limit, or if connected to your motherboard, your motherboard isn't configured to read it, so the controller only knows to provide a preprogrammed range of voltages, not accounting for different loads and voltage requirements.

33C on a hard drive is perfectly normal. I've seen hard drives run for nearly a decade, 24/7/365 inside a DVR inside someone's dusty cabinet, starved of airflow, at nearly 50C.

Okay so i should stop worrying and just wait until it really dies. And when it does just replace it i guess? I noticed that even without the 200mm front fan my other temperatures in the case dont rise with it. So i guess the case airflow on its own is pretty good.

With the way case airflow studies have typically concluded, it's far more crucial to have exhaust fans than intake fans. PC fans aren't very good at generating a ton of positive pressure, as noted by how few fans work well with radiators, and how expensive they are. Balanced airflow within a PC enclosure is ideal (equal intake and exhaust), but under extremes, having only an exhaust is preferred to only having an intake, especially since cases are designed such that the exhaust fans are very close to the hot components, but intakes are kind of far away.

Don't worry about that thing until it actually grinds to a halt. Fans don't die that suddenly anyway (unless you stuffed silly putty into the motor housing).

Alright thanks for the help.
