    Control CPU & GPU fans?

    So basicly i was wondering it is possible to make my cpu fan run at a small level at all times? I have a Zepto Nexus A15 which fan often starts running like crazy and its so annoying.. and this is one just doing nothing! Ive underclocked my pc and only using one multiplier (RMClock)..

    Some of you might know theres a BIOS update for those Zepto laptops with this problem which allows you to choose when the fan shall kick in (55, 65 or 75 celcius) But it doesnt make sense because if i choose 65, it just starts when its around 65 celcius and if i choose 75 it does the seem.. it just increases but it doesnt get above..

    So instead of running A LOT once in a while (often), i was wondering if theres a way to make it run at all times but not so much, like just to keep the temperature down a bit.. and if its needed it will increase and cool even more (and make more noise)


    Any respondses appreciated!



    Thanks

    The fans are controlled by BIOS instructions, so it isn't possible to use software to control the fans unless you have a Dell. Besides undervolting, you might want to consider applying thermal compound and cleaning out the computer for any dust that may be stuck in there.

    Well its probably not the issue, because it does just start when it hits whatever temperature ive select.. When it starts it quickly decrease the temp on both gpu and cpu with like 10 celcius.. but they slowly go up again and repeat...

    Hmm, could you explain some more about thermal compound?


    Thanks

    Thermal compounds are substances that are applied in a thin layer onto the CPU die. The purpose of a thermal compound in the context of a computer is to ensure maximum heat transfer between the surface of the CPU die and the surface of the heat sink. This results in lower overall operating temps for the CPU.

    Applying some TC yourself is beneficial because many manufacturers skip on using high-quality TC and sometimes use thermal pads instead; the result is that more heat builds up on the CPU and less of it is transferred to the heat sink. This in turn can cause the fans to turn on more often because the CPU temp is higher.

    Applying TC is very easy if your laptop provides easy accessibility to the CPU/heatsink assembly. Head over to the Hardware forum and search the general hardware sticky for the cooling guide; it'll give you the specifics on how to go about applying TC.

    Many manufacturers aren't exactly clear on what is a consumer upgradeable part and what is not. However, for most manufacturers it does void the warranty... if they were to find out. Applying TC is a fairly low risk upgrade if you ground yourself, be patient in dismantling the machine, be systematic, etc.
