    Acer Aspire 5738G fan runs almost constantly

    Hi

    I bought an Acer Aspire 5738G last week and am very impressed by it apart from one thing ..

    When I power on, after about 5-6 minutes the fan (I assume the CPU fan) kicks in. However, it then seems to remain on constantly until the laptop is turned off, even if I'm only idling. This is slightly annoying, not just because of the noise, but also it seems to have quite a noticeable effect on the battery life.

    I have installed SpeedFan to keep track of the CPU temp and it seems that the fan kicks in initally when the core temps reach about 35 C, but then the fan does not switch off, even when temps drop back down to 25/26 C, which seems very cool.

    On every other laptop I have used (none of which were Acers), the CPU fan only comes on now and again, as and when it is needed.

    So, is this normal behaviour or is there possibly a fault with the fan control mechanism ? If so I will consider taking back to the retailer for an exchange.

    Thanks in advance for any help.

    I'm getting an acer 5738g next weeked, i'll let you know what my cpu fan behaves like.

    Other than that, how is the 5738g? Are the specs good for what you paid, is it powerful?
    Just want some opinions before I buy it.

    Yeh it's a nice laptop, looks good and very good specs for the price I paid.

    Are you buying in the UK? If so Comet are selling for £499, but you can use the voucher code "5300AW" for 5% off, and also cashback through quidco for a further 3.5% off. Brings the cost down to just over £458 which is the cheapest I've seen

    Viglen, welcome to the forums!
    Keep in mind that the fan cools not only your CPU, but your GPU as well - they share a common heatpipe.
    And there's also no guarantee that SpeedFan is reading your temperatures right. Try RMClock, HWMonitor, CoreTemp, etc.

    If you want, you can try to undervolt your CPU using RMClock to drop temperatures further AND extend your battery life. There's an excellent guide to do it here on NBR.
