    Fan speed locked at 35%


    so I am using a laptop with switchable graphics card and I am just wondering if this is normal.

    these are the temps before putting heavy load on the gpu

    then these are the results after

    I noticed that the fans are always at 35% and it does not rev up even when the GPU is loaded

    Am I frying my hardware? I never changed any fan setting or something (the laptop does not have settings/software for it)

    Fan controllers go by temperature, not load, if your temps are good, fans should not increase rpm.
    Although, some measurement results do look screwy, GPU fan At 10334 rpm, ??? Which program are you using for monitoring ?

    I use HWinfo

    btw that test lasted for like 5 mins,

    If I play for hours, temps can increase to 70 degrees and for such a thin little thing like this im a bit worried

    Which GPU do you have ? Try : MSI Afterburner and see if it would show results better or even let you control fans.

    yeah I have that one, too

    when I start a game the fan speed registers at around 500-1800 rpm

    then at 60 degrees and above it throttles down

    is it okay to tinker with the fan speeds?

    EDIT: I guess it tries to maintain 65 degrees? i noticed the fans speed up if the temp goes up 65

    is that temperature range normal?

    If it would let you, go ahead, just don't lower it. It works differently on different GPUs, some get more options some less. I do have a MSI video card and still don't have all the options.
    Which GPU do you have there ? AMD for instance has direct fan control in latest 14.2 Driver control center.

    it's actually a switchable graphics card

    Radeon HD8530M

    asus has not released any catalyst update so im stuck

    but whenever i try to install the latest mobility drivers with the ccc it recognizes it as r5 m240

    You don't really need Asus for that. According to Download Drivers v14.2 should work.
    I chose: Notebook graphics/ Radeon HD Series/ Radeon HD8xxxM/ Windows 8.1 x64 and it offered to download 14.2 drivers. Those two graphic cards may share same GPU and that's why it's cross referencing to R5 240m. AMD has rebranded some video cards to Rx xxx. For instance, my R7 260 is rebranded from HD7790, all except for it's BIOS is exactly the same on both of them. Manufacturers (like Asus, MSI, Gigabyte etc) don't usually offer newest drivers which can be had from AMD.

    that was what I did last time and it didnt really work properly

    I mean the graphics was being detected as 2 separate graphic cards - intel HD4000 and R5 240m but the catalyst control center will not open

    additionally, the screen will constantly flicker at times and a notification balloon pops up saying display adapter has recovered successfully or something like that.

    If I'm not mistaken, you have an I3 processor with graphic (4000) on the chip and a separate AMD mobile card.
