Am I worrying too much? (PC related.)

[Ferth]

You probably are worrying a shade more than most people would but if shutting your pc down when it starts to get warm makes you feel safer then you aren't hurting anything (unless you are excusing yourself from parties to restart your pc...)

In short if it helps with your own peace of mind to be extra careful, go for it.

Ok, i am too a paranoid person when it comes to the fan noise.
I have built my computer recently and i have no problems running the game, but fans on the other hand..

Anyway, if you are using a program called smart doctor which comes with asus motherboard package (It's in the disk) i would suggest you to shut it of, because A: It adjusts the gpu fan speed automaticly/manually, that is unnecressary feature to the already build in auto adjustment.

(I myself have disabled smart doctor and i'm running the other fan speeds via AI suite from asus and the temperature and noise are reasonable.)

If your game is being slow or whatnot it's because your gpu or cpu is overheating and therefore makes the game slow down, it may also occur when the ram capacity is reached..

Check your computer cooling system and stay with the normal fan speed 50% fanspeed or auto speed, do not hastle with them if you want less noisy fans

Get more fans better cpu, check the thermal paste on your cpu (clean cpu with 100% alcohol) and put new thermal paste on the cpu and better fan on the cpu after.
