    Adding a smaller fan you are unlikely to see a noise reduction.

    just have to put up with it. tbh right now the 2nd gpu fan is quite loud even though theres nothing its cooling other than internal hardware like ssd/mobo. cpu is very quiet, i wish i could up it a bit so my regular usage temp doesnt spike to 79/80c, basically doesnt seem to fan start to spin until like high 70c or at 80c, the software ccc simply wont work on server OS..which is literally just windows 8.1

    hope the added fan will lower those by 3-4c.. fingers crossed. fan should arrive in a few days, 42*50*5mm type, only 3.3v and 0.35A. just purchased other fans 6mm/7mm types .5v and .5Amps and will compare difference.

    below is 24/7 4.9ghz on default fan profile by clevo, auto fan profile.

    Clevo fans I tested have voltage protection set to 6V. On this voltage level fan enters "hiccup" mode.
    6V supply for 5V fan is 20% overdrive. For 3,3V fan this will be 3,95V max.

    so you would need a 6v fan?

    No, just 3,3V fan isn't good choice. Standard, 5V, 4-wire fan, like in Lonovo's, will work fine (of course, if this fan output is enabled in EC).
